Dreambox 800 HD and SE cooler embedded

[Triad]

Ok, since there were needs for infos on how to install laptops 5 volts cooler into dreambox 800 HD, I decided to give this info to other users who are willful and brave enough to implement this procedure, which is quite easy, into their HD "pet beasts"

I'd like as well that this thread be put to sticky as this is quite good job that will considerably prolong life of your HD pet beast!!!

So here we go:

##############

In short i connected scart behind in order to get cooler to turn off when I turn Dream over remote control. That method is much better then the one mentioned somewhere where the guy connected it simply on 12 volts on USB internal slot! When connected on scart it is connected on 5 volts, not 12 since Enigma only needs 5 volts to operate while 12 is used only in reset process while Enigma is booting up (you can hear cooler ramping up in high speed while Enigma in boot mode) as soon as Enigma enters some channel area cooler is quite noiseless and in 5v volts mode as well!

Temperature is down by even 50%!!!

While cooler is concerned, I set it up with black tightening cables which I've got with dream in it's original packaging. With the cables, from within in the inside of the dream cover of the housing I connected and tightened 2.5 x 2.5 cm AMD cooler.

It is positioned a few millimeters of the tuner in front of the red cable which needs to bi gently pushed backwards so cooler can fit in nicely.

There needs to be POINTED OUT: COOLER NEEDS TO BLOW THE AIR OUT, NOT IN !!!

If you position the air blow fan current inside or in the processor area, you'll only worsen all the job!!! To clear that out first!!!

All you need to do is to solder Scart [B][COLOR="Red"]Pin 8[/COLOR][/B] or 12V current + with black (12V) wire of the cooler, and [B][COLOR="Red"]Pin 21[/COLOR][/B] or ground wire with the ground white wire of the cooler!!!

So cut the old scart cabel and open the Pin housing, by the diagram below find Pin 8 and Pin 21, and connect pins solder it with cooler wires!!!

Description of the pictures:
Picture 3 is Scart diagram, where Pin's are located, pay notice to pins 8 or 12V current and Pin 21 or ground wire!!!
Picture 21 is Scart housing opened and connected with Pin 8 Red wire and Pin 21 Black wire
Picture 1 Is the cooler and scart connected.
Picture cooler 4 Is connecton of the cooler from inside the housing positioned to blow the hot air out, and fastened with black tightening cables.
Picture cooler 3 Is the same description as previous picture but with clearer 90 degree view!
Picture cooler 2 Is Dreambox 800 HD connected and fastened with black tightening cables from outside. you can see point of entry of the scart cable into the cooler in the housing as well !
Picture cooler 1 Is the same description as previous picture but with different angle view!

Cheers and don't be afraid or hesitate in any way to try and do this !!!

i suggest that you use a imagehost like photobucket ETC
or else the pics will disappear in a month or 2

Re: Dreambox 800 HD and SE cooler embedded

you can get 5v power supply from the sata connector:

__http://en.wikipedia.org/wiki/Serial_ATA

with

Pin Function
1 3rd 3.3 V
2 3rd
3 2nd
4 1st Ground
5 2nd
6 2nd
7 2nd 5 V
8 3rd
9 3rd
10 2nd Ground
11 3rd Staggered spinup/activity
(in supporting drives)
12 1st Ground
13 2nd 12 V

so, pin 7 and 12

Hi aplok

Can we use the e-sata port from outside in order to connect an external fan?
Are the pins the same?

Re: Dreambox 800 HD and SE cooler embedded

there are many SATA variant connectors: SATA, eSATA, eSATAp ...

here is a description of some of them with pics

__http://en.wikipedia.org/wiki/File:SATA2_und_eSATA-Stecker.jpg

for

3 Cables, connectors, and ports

3.1 Data connector
3.2 Power connectors
3.3 eSATA
3.4 mSATA
3.5 M.2 (NGFF)
3.6 SATA Express

and this can help

__http://en.wikipedia.org/wiki/ESATAp#cite_note-3

where i read this

eSATAp combines the functionality of an eSATA and a USB port, and a source of power in a single connector. eSATAp can supply power at 5 V and 12 V.

and sometime all of this confuses me, just as following:

__http://en.wikipedia.org/wiki/ESATAp#.2B12_V_issue

There are only two versions of this port. Most laptop computers do not have +12V power available, and have an eSATAp port which provides only +5 V. Desktop computers, with +12V available, have a port with two additional pads, placed against the plug's "horns", which provide +12 V. Some manufacturers refer to these ports as eSATApd, where d stands for "dual voltage". Some devices, such as 2.5-inch drives, can operate off the +5V supplied by laptop eSATAp ports. Others, such as 3.5-inch drives, also require +12V; they can be powered from a desktop eSATAp port, but require an external +12V power supply if used with a laptop computer. This can lead to confusion if users are not aware of the distinction.

conclusion:
this issues needs some careful investigations
