Seems like a fan is needed for my device.

Do they have full contact to the chips?
What is the material of the heatsinks?
Yes i have thermal compund between heatsink and alu plate. Heat transfering is ok, with ir-gun heatsink is 60c under load. It is just so much heat for a passive fan to get rid off, i see no way to get this to below 60c without a fan.
And this is with the pcb outside the case even. I see our boardlayouts are not exactly the same.Last edited by Trhuster; 02-21-2015, 17:31.

Waiting for mine Pipo X7 to arrive and was wondering if anyone has removed the factory thermal pads and aluminum and stuck heatsinks directly to the cpu, pmic, and ram? Wondering if anyone could give me the size of the of the cpu, pmic, and ram chips. Thinking about installing the heatsink directly to the chips.

It is obvious that you do not have proper contact between the chips and the heatsink. By using a large continuous heatsink, you may have lifted the metal plate a little bit, so the stock thermal pads do not ensure proper contact between the chips and the metal plate. Remove the metal plate and replace the thermal pads with good quality ones. You may have to use thicker thermal pads, soft enough to be able to be compressed. If I were you, I would try using some compressible Phobya Ultra 1.5mm or even 2mm ones.
But i shall change out the thermal pads just in case it and see if it helps anyway.

So its obvious that you don´t have proper contact between the alu plate and the heatsinks.

So much heat.

So much heat.
2. Take a voltage stabilized power supply (maybe from an LED).
Look her:
C'est confirmé, les chargeurs livrés avec les Mini PC Pipo X7 sont responsables des pannes rencontrées sur la machine ces derniers jours.
3. Did you change any UEFI settings. Maybe you load optimized defaults.

Just a question, as I'm still waiting on my box from GearBest for 1,5 month now.
Is there a reason no one has tried to take a strip of aluminium or copper and connect the center to the heatspreader and the ends to the top of the case? That way the case can be used as a heatsink (as Pipo should have done in the first place).

PS! I took this picture when fans spinning full speed, impressive camera!
