very good idea to flip it it never come to my mind .
now i know what i want , only thermal pads and flip it over
i will try that when i got the pads

I flipped an unmodified unit over and placed it on an angle (chimney effect to increase air flow). Running Hulu under Chrome, with 20C room temperature, the core temperature is alway less then 13C from TjMax (about 55% processor utilization). Running the unit "un-fipped", it would overheat in about 20 minutes.

i just Googled it and that's what i found about chimney effect

In principle, a chimney stack is a tall pipe. Hot gas, from combustion, enters the chimney and rises to the top. The chimney is sealed against the furnace/fireplace and the only way for fresh air to get in is on the draft side of the fire. The rising air in the chimney stack creates a vacuum and air is pushed in, by the ambient pressure, into the system.

is that means i should make the device stand vertically on it's side ??

As not to block the side ventilation slits, I have the unit leaning at about 75 degrees.

I had the same issu like you do, same board 1.3
I put this on Thermal pad XT 1mm, 7W/mk (120x20mm) Phobya

http://www.****.co.uk/itm/Phobya-The...-/331498394896

Now I have 52 C at full load for 30min

So all you changed was the thermal pad on the processor and you dropped to 52 degrees? I did the same thing + heatsinks and I'm still pushing 70 degrees...

You're on the right track. You did like me and ordered prior to receiving the Pipo. I ordered the same heatsinks from ****. They are about 2mm to tall but will work, they are in mine currently. I have since ordered another set of heatsinks with dimensions of 25x25x12 mm so that they fit a little better. Good luck, Kevin

hi friend,
what is the model thermal pad you used in your mod,
can you share link with us,
thank you very much

I've modded my Pipo X7 with a 5mm thick CPU VGA heatsink silcone paste thermal pad, placed on the underside of the motherboard, placed 8 14*14* 6mm aluminum heat sinks on the CPU (I removed stock cooler pad), placed on top of the metal cover. Streaming a 1080 movie on Kodi over 1 hour and unit is running way cooler.

Yes that was all I did. The original therminal pad is a joke.

I can't get the link to work. I would use the 100x100x5 mm, 5w/mk, blue pad posted by Loko yesterday. I don't believe my pad is a very good one because they do not display what w/mk the pad is. As a matter of fact I will be upgrading my pad to this one. Good luck my friend.

Hi everyone,
it's there anyone who already order this thermal pad
http://www.****.com/itm/EC-360-BLUE-...68&mfe=sidebar
and like me will not use more then 30mm*50mm
Scooby-Doo post 126,

and it's agree to sell what are it's left from the thermal pad!
Don't understand me wrong I just want save money,
because I'm pretty sure there is no one here,who are thinking,
will have to mod his box and gave maybe 1/2 from the real price of the box!
I hope you understand me what I wanted to tell,because my English it's very bad!
Thank you

I would use the blue pad you were asking about.

Finally, I got good thermal results.


I bougth 1 mm pad: http://www.****.de/itm/121159893475


Pictures of thermal pad, heatsinks 12 mm and 15 mm





For the box cover downside, instead this pad mix I put 5 pad pieces of 1 mm pad, that was very useful.

Now, only extrem stress* goes up to 70º, normally 50º-60º on heavy load.

And here another cap comparing Netflix running with chrome and IE, the higher are chrome, the lower are IE:

I am glad to hear about your improved performance. By using a 100x100x5 mm thermal pad on the bottom, I believe the temp should drop by another 15-20 degrees Celsius . Good luck. Kevin

There are some tiny holes on the metal plate, so you cannot use Arctic Silver 5, because it may enter the holes and short some circuits underneath. The chances of this happening are close to zero, but better be on the safe side.
Make sure that the heat sink cannot slip out of its place, because it will short some circuits and fry your device.

I'm not sure if I did a right thing by buying a Silver Alumina Thermal Adhesive to connect heatsink with metal plate. On official webpage it says:
"It is NOT intended to be used between a CPU and the CPU heatsink. On a CPU please use a thermal compound such as Arctic Silver 5, "
What do You guys think?
I've also read opinion that removing a metal plate can be difficult and it's better not to do so unless it's required.
But than again isn't it more risky applying thermal adhesive on metal plate without removing it first? I mean this can result of getting thermal adhesive inside metal plate via the holes as you don't have any control.
In my opinion it is more reasonable to firstly remove the metal plate, stick heatsink and than remove overdosed Thermal Adhesive.
Can You please guys advice how to remove metal plate? Can I do it with just fingers (pushing in specific direction) or do I have to use specific tool?

Thanks in advance.
Michal

I just took the plate off with my hand
