Hi, kamel_hail:), naveed68:).

Good cooling kit - better than attaching an original little 60 mm dreambox fan to hdd-casing fan holder.

My new fan is situated exactly at same spot, as the fan from cooling kit on photo is - but it´s no dreambox fan.

I bought this one

http://www.amazon.de/Noctua-NF-B9-P...KYPE/ref=sr_1_1?ie=UTF8&qid=1340156569&sr=8-1

With the included 4 rubber fixings, I attached the fan to the dreambox´s metal case on top. I first pulled the rubber fixings through the air inlets and afterwards through the screw holes of the fan. The fan sits tightly as if it was glued onto dreambox and it is placed exactly on the same spot, where it would be with dreambox kit on photo.
My fan blows same direction as on photo, too. Usually a fan blows in direction of its own label/power cable - which means in this case, it blows warm air outside the box. When I hold my hand close above my dreambox, I can feel the airflow although I can´t hear the fan.

Perhaps I should make photos, too, when I attach next fan to next box (Will have to wait for extra rubber fixings to come - ordered new ones, because I tore two original ones to pieces. Should have been more patient ...

Must quit now - it´s getting late and I didn´t have much sleep the last nights.
(Didn´t even have time to play a game, today:mecry:. Still pllaying Thief3 fan missions. Will take some time until finished ... After I saw, how many good missions other people have built, I tend to quit building the one of my own, that I had started with - it´s lot of work.)

:)hi ara hi kemel thanks for the useful posts on cooling systems i think the kemels fan gets my aprovel ara ..

allthough im not to keen on fans being on top of boxes as you may as well be just be collecting dust and filling your dreambox up every day with dust .

i think the best solution is 2 small 6 vault fan motors attached to the side housing of hard drive case sideways and pointing towards power supply and processer and solderd to main board and a fan like kemels but blowing the air out ill rig something up soon when i get some more time.

thanks ara for testing on 0e2 i hope you can stick with it ara and resolve the issues and stick with oe2 as i have found your help most useful :thum:

Hi, naveed68:).

Yes cooling kit is very good - I looked for it at amazon, yesterday - it´s available.
If I had known, I would have ordered it. But I´m not sad about that.

My own solution does the same - only , without the fan being attached to hdd cage but attached underneath housing cover of the dreambox.

You misunderstood:
My fan is inside the box - not on top. (On my photo above, you can see the four tiny little rubber fixings - all you can see from the outside of the dreambox - but the fan really is INSIDE, already)
My fan doesn´t collect dust - it blows out the dust exactly the same way as the cooling kit fan does (it blows air into the same direction).

advantages:
My fan costs only half of cooling kit, but has same cooling efficency
No hdd fixing screw from hdd cage needs to be removed as with cooling kit.
When you open dreambox - the fan is attached underneath the cover. Just unplug it from its 30 cm extension power cable and it is completely out of the way for maintenance purposes.

disadvantages:
- you can see the four heads of (silent) shock absorbing rubber fixings on top of the box. (I don´t mind, they are tiny and one shouldn´t place any other devices on top of a dreambox anyway.)
- My fan is open towards mainboard and not covered by protective wire frame like cooling kit fan is. So cables on mainboard should be out of its way.

Well - I´m very satisfied. I don´t hear anything. I always think the fan is not working, but when I touch my dreambox in standby, I think it is in deep standby - very cold where it always used to be very warm:D.

---

For heaven´s sake don´t ever attach two small 60 mm fans to dreambox, naveed68 - you will hate it - you´ll have the noisiest box you can get!:eek:

One 60mm fan is bad, already, but two?
Noise is why I replaced my original 60mm dreambox fan by Noctua 92 mm - dreambox with one 60 mm fan sounds like a cheap crappy box.
I once had an Abcom IPBox9000HD as loud as this - I´m glad, I don´t have to use that one any more ... you always heard it, when it was switched on.

---

When all components, that I ordered, will have arrived (new rubber fixings + 2.5 to 3.5 hdd adaptor), I will insert new hdd plus Noctua 92mm fan in my second dreambox. Perhaps I have time to make photos and upload here.

Must quit for now.

hi ara as long as you have the fan pointing upwards and blowing the air out its ok as it will extract the heat from the dreambox.

a lot of dreambox member have reported just using a usb fan just sat underneathe the box actualy cools the underneath of board and works better but i yet to try this

but it doesnt matter if your fan is on top of the box or underneath the lid its still on top of your box as long as your fan is blowing the air out you have nothing to worry about i hope..

yeah ill leave that idea i think but the fans are not the sought your talking about there half the size of kemels and there only 6 vault so less demanding i could fit them to the sides of dreambox inners if i wanted to but like i said my temps are with in range of maximum temps for proceesers and boards etc without the aid of fans so i just leave them off


im sure that dream multi media would of tested the dreambox to the hilt with every single port being used and internal ports and where quite happy to sell there flagship model with out fans
personaly though i think all talk about fans on dreambox 8000 comes from the old 7020 when they had heating issues and power supply problems the dm8000 is a long way away from the old 7020 and i dont have any issues my dm8000 is left on 24 7 temperture in there 50s been like that for 3 years aprt for a few months when i got a bit paronoid after reading people complaing about no fans on dm8000 ..


but i removed as there noisey and cause extra strain on power supply and there not needed..

you should know this from pc you have made tha processers and board can quite happily run run and run at 52 celsisu 54 etc

for instance when playing 3d games on my standard fans on pc my temps would reach 60 celsius and they would go higher if i let them so i had my pc set to switch of if temps reached above 60 i never had any issues even at them temps but to be on the safe side i fitted a water cooler and now temps never go above 52 celsius when im playing high demading games and in 3d which are even more high demanding i have my pc proceesr running at 4.2 ghz it just eats everything i chuck at it i have been thinking about a satellite pc card for a while now but not sure which one i would get but i bet my pc could wipe the flooor with dreambox or any other sat box that is ...:thum:


anyways im going to call you captain ara from now on in your motorised leather chair haha:)

its just an idea but dream multimedia should have some software on board that warns you if temps are to high and they should be more info on limits for all the reading you get from your fan control plugin as i think that would stop a lot of undue worry :)

Hi, naveed68:).

When you install a fan and control it with plugin "FanControl2" - you can set warning options. So there is warning software, already.
But better, if warning without installing a fan possible. You´re right.:thum:
Don´t know if a plugin/function exists.

Without fan dreambox can show hdd temperature, I know. (e.g. in GP3 Blue Panel) There may be more plugins that show temperatures. Don´t have the time to search at this moment.

You are right - pc components work ~ up to 70oC without failure.

But, dreambox works better, when cooled down.
In cool dreambox no "Tuning Failed" messages.
Hot dreambox "Tuning failed often.



but i removed as there noisey and cause extra strain on power supply and there not needed.. ... And you were right to remove these small fans! They really are loud!

Bigger fans are silent. (Can´t hear mine.) Bigger fans are not too demanding for dreambox. They run at lower speed. Small fans must run much faster:
60 mm/6 vault fan with 3300 rpm = loud
92 mm fan with 1300 rpm = silent plus cooling is better


kamel-hail´s cooling kit uses a 92 mm fan = good and silent
In my box1 is a 92 mm fan = good and silent
only difference is, how installed in dreambox

In my box2 I still have old 60 mm fan. It is bad and loud. I will replace it by 92 mm fan. Then I will make photos.
I also will attach new 2.5 hdd and make photos.
(Have to wait - still must buy some parts.)

Why XFS filesystem instead of Ext3/Ext4? - you once asked.

Better performance - have a look here (all pages - on first page, XFS is not the fastest):
Compared with Linux kernel 3.0 - which is in OE2.0.

captain ara? :laughingmouse:

"Ara" in german is a "parrot" (macaw) = one of these nonsense talking coloured birds.
The name fits / is suitable :D:D

:cool: haha now i am a big fan of you ..

ara in german is parrat haha i was thinking ara short for ararat..

but now im thinking your half parrot half rat haha :eek:..naw naw



thankyou for your most usefull post i think this has well and truly cleard the fan situation out now i once emailed dm to get response about temps and limits but i got no reply...

i suppose i could heat them up to find out but ill give that one a miss untill im ready for an upgrade :nana:

i think i might invest in one of kemels fans then but i never get tunner message fail but i dont have a 3.5 in my dm so that might explain why as 2.5 equals better airflow throgh dreambox ..
however i did notice some jumping on fta channels last night only verry very slight jumping and it was prolonged so maybe you could be right about the temps interfering

ill have a look at your xfs info later thankyou for sharing the info its allway appreciated as allways :)

cheers hav a groovy woovy day:thum:

Hi, naveed68:) and all:)

(If your box runs fine, naveed - why change anything? Never touch a running system;). Only if your box has problems like e.g. "Tuning Failed" or faulty recordings.)

Finished an hour ago assembling new 2.5 hdd plus 92 mm fan into dreambox2.
Made many photos - then reduced photo´s size to 25% on pc - and zipped them - 12 pics.

Now my two dreamboxes are really cool and absolutely silent. Nothing to hear, even when both are recording:D. Hopefully recordings get flawless, too.

1TB 2.5 hdd with XFS is even MUCH quicker than 2 TB 3.5 hdd :) (maybe because of cluster size).

I didn´t format my new hdd with my dreambox.
I used Knoppix CD and created movie folder with Knoppix (hdd must be opened as root, of course).
I´m telling about this, because some users are complaining on DMM board at the moment that formatting and mounting is not possible with OE2.0.
I had no problems - but only because I formatted with pc/Knoppix when hdd was outside of the dreambox.
So, if somebody wants to attach new hdd - download Knoppix - burn it on CD, boot with it, format hdd with e.g. XFS or EXT4 (EXT3) and create "movie" folder.
Then hdd can easily be mounted with dreambox. (Don´t forget to choose your harddrive in Settings/System/RecordingPaths or else no recording possible.)

hi captain ara :) hows the recordings going and hows the leather chair..

i can just picture you sat with yer feet up twiggling your toes reading this thread haha :rolleyes:

i can not find any eveidence to suggest that xfs is a better file system than ext 3 all the research i have done sugests that ext 3 is faster so i think i will stick with ext 3 for now unless i encounter problems.
im telling you this as you are going to a lot of trouble to get flawles recordings and you once said that someone on dm board told you not to use ext3 (my honest opinion to that is if this was true why havent dream multimedia implemented it as standard maybe someone at dm was just palming you off :eek:

i did have probs mounting my hd when i first setup image some 3 weeks ago but i think that problem was resolved after software update as now i have just reflashed image and i was able to format and mount straight away without any issues.

maybe you might want to try setting your dreambox to 720p as did you know that all satellite broadcast are 720p and not 1080i so in theory all the dream box is doing is upsclaing and doing overtime to upscale to 1080i .. setting your dreambox to 720p will help to keep your temps down to witch in thoery you shouldnt have to run your fan and you will have more power from dreambox . im not saying that this will correct your issues but i have read of many probs with dreambox satellite tunners in the past so maybe your issues may lie there i have had a 2.5 sata with box set to 720p and i allways have flawless recordings.

cheers all have nice weekend :thum:

:)hi kamel hope your enjoying your weekend

auto resolution plugin i love this plugin as you can set it acorrdingly to broadcast which means your box isnt upscaling .

i am no fan of upscaling as for me its just fake and just makes your box work harder

enable auto resolution = yes

s/d 25/50hz interlace mode = 480 i ( this setting is used automaticaly for satellite standard def broadcasts in europe which are broadcast at 480i this setting would also be used for any recordings you have made onto your hard drive from standard definition channels.

s/d 30/60hz interlaced mode 480i ( this would be used for an american satellite sd broadcast in america) your dreambox would automaticly use this if it reconised a 60 hz signal coming in which doesnt effect you if you live in europe only in usa as there electricy mains run on a 60 hz signal.

s/d 25/50 hz progresive mode= 480p this would be used automaticaly if you put a dvd standard definition disc into your dreambox most standard definition dvd discs are 480 p

ok i will leave the 60 hz settings out now as it only applys to america

hd/ interlace mode = default ( the default setting for drambox auto resolution is 720p this is what hd satellite broadcasts in europe is broadcast in (again your box would automaticaly use this for hd broadcasts and any hd recordings you have made onto your hard drive.

hd/ progresive mode = default this is for any hd dvd discs you may have i do set this higher sometimes it depends on the disc.

ok the rest of setting are for bluray files on my hard drive


i personaly use these setting for my panosonic tv as i get better performance on smooth playback at 24 hz seting on my pani in 3d settings but you can set these acordingly to your files and tv ( as for me these are not as important as interlaced mode settings

enable 720p 24 mode = 720p at 24
enable 1080p 24 mode = 1080p 24
enable 1080p 25 mode 1080p 25
enable 1080p 30 mode = 1080p30
refresh rate 720p 50hz
refresh rate 1080i 50 hz
show info screnn yes
delay x seconds after service starded 1 sec

ps im not sure about any other type of formats you may have fttp to your hard drive as i dont use any other than bluray ..

ok for av settings on box i leave every thing as default the only things i set in there is (video output = dvi and mode = 720 p
i also set refresh rate to 50 hz as europe runs on a 50 hz signal from the mains electricity so best not to set your dreambox to 60 hz

hi naveed68:), kamel_hail:) and all:)

720p / 1080i HDTV - both are being broadcasted (about 50% each in my case).
720p many FTA HDTV channels / 1080i some FTA HDTV and some SKY
Setting a dreambox to fixed 720p would therefore be no good idea.
---

But, as you already know, one can use plugin "Autoresolution" to set everything to one´s own needs, if necessary.
---

My faulty recordings are not due to hdd recording speed (XFS - see down below).
My recordings get spoiled, because I have two dreamboxes connected. You don´t have the problem with only one box, naveed68. Me too, I don´t have faulty recordings any more, if only one box is running separated from the other (no matter which one - both work ok., alone).
It´s an emu-requests-over-the-network problem that you don´t have, naveed.
On one of my boxes I already get 100% flawless recordings again, the other box has improved - most recordings o.k.:).

-----

XFS´s advantage is not recording speed. Ext3, Ext4, XFS all are fast enough to do multiple recordings at the same time.
It´s all about how efficient CPU is being used. Especiallly important since OE2.0 firmware. It´s about 40 MB bigger (~ 92 MB) than OE1.6 (~ 52 MB).

XFS is already inside OE2.0 - you only cannot choose it in menu (,yet), but one can use it with telnet.
After initialization of an hdd with Ext3 in menu and after unmounting that hdd in telnet with umount /media/hdd
e.g. you can format a 2TB hdd with XFS in telnet
mkfs.xfs -s size=4096 -L hdd -f /dev/sda1
if your harddisk is "sda1" (you can find out with: fdisk -l -u )
("size=..." - necessary for 2TB hdd - otherwise big clusters and very low performance)

howto XFS in telnet:


The "guy palming people off" at dmm is programmer/developer of Enigma2;) - of course he doesn´t have the faintest idea of, how Enigma2 works :D.

-------

By the way XFS: initialization, mounting problem with OE2.0:

Problems with mounting HDDs on OE2.0 can as well be overcome with flashing box anew.
AT FIRST START ONLY OF THE BOX AFTER FLASHING, IT´S NO PROBLEM TO MOUNT AN HDD.
Mounting will work correctly, automatically.
Same counts after flashing and restoring your old OE2.0 (not OE1.6) settings.

So, you may find my Knoppix solution mentioned in my post above helpful only, if you don´t use GP3 and don´t want to flash your box with new firmware.
(In my case Knoppix was just the easiest way. I had to open my dreambox and remove hdd anyway for installation of a fan.


YOU CAN AS WELL USE GP3 TO MOUNT HDDs AND AFTERWARDS IGNORE MESSAGES IN CVS DEVICE MANAGER
(... telling you, you have to initialize your hdd. Don´t do that, if you mounted your hdd with BluePanel of GP3)

Mounting procedure should (hopefully) be improved in future firmware.
------

"Tuning failed" - no more message since installation of fans in both my boxes.

-----

Have a nice weekend, all and fun with EM.
I´ll watch in my leather chair;):D.

Hi, naveed68:) - the naveedgator:D
kamel_hail:), tomcat:) and all:)

Read this: http://en.wikipedia.org/wiki/High-definition_television

Where I get the information from, which tv-channel broadcasts what standard, 720p or 1080i?
Easy.
Press menu button on your remote control - choose "information", choose "channel" and there you´ll find all the information about the channel, that you are just watching;).

If you receive Astra 19.2 oE, try fta channels like "Servus TV", "Anixe HD" and you´ll be very surprised to find 1080i.
I´ve got 16 fta 720p channels in my HDTV bouquet.
I´ve got 6 fta 1080i channels in my HDTV bouquet (some only 1440 x 1080i, some 1920 x 1080i)
I´ve got 15 HDTV 1920 x 1080i channels in my HDTV bouquet from SKY pay-tv.
I probably forgot a few.

I just recorded Once Upon a Time in the West - Italo Western - Sergio Leone - if you know, from free to air channel "Servus TV" on Astra 19.2 in 16:9 _ 1920 x 1080i _ Dolby AC3 5.1.
Later I ftp-ed the recorded ts-file to my pc.
There I cut the movie, removed unneeded audio and converted it into MKV (and, NO - the resolution of the movie was NOT upscaled by this conversion - it had the same resolution before).

I attach a txt-file here for you to read - it was made by a program called "media info", which tells what video and audio is in a movie.
Important are the figures behind "Width" and "Height", which are 1920 and 1080.

I sometimes write such movie-files to disk (with disc writer in my pc) and play them with bluray player.

Satellites don´t have the bandwidth for 1080p (better: providers don´t want to use up too much bandwidth for only few broadcasts - it´s a matter of costs) - but it´s no problem with 1080i. But, you are right, that it really needs more than 720p.

My leather chair is calling ....;):)
