Default Pipo X7 - Anyone has tried it ?

Hi !
i would like to show you a little and cheap pc that i have found in the web

Pipo x7 Windows 8 1 Intel HD Quad Core Smart PC Internet 1080p TV Box 2GB 32GB | eBay

Click the image to open in full size.

It comes with Win 8.1 Bing preloaded (very nice feature indeed. The OS alone costs almost like this pc).
i have the feeling that it has a high potential for audio in particular.
The sound is better than with my other win 7 bigger pc.
Problem is that the cpu tends to get hot. I reach 80 C during normal use and i guess this is too much for reliability.
I am attaching a picture of the board (the cpu is under an aluminum lid without heatsink).
The space between the board and the top cover is very limited.
Any idea about how to cool this cpu down a little ? possibly with a passive system ?
Thanks a lot, gino

Looks like they're using the black thing as a thermal interface to use the entire chassis as the heatsink, which is a smart choice. However then the 80 degrees would not make sense as a good contact between CPU and case would result in the case reaching 80 degrees too which is not safe. There is some contact problem somewhere, fix that first.

Hi and first of all thanks a lot for the kind and helfpul reply.
Yes, that would have been a smart choice if the thermal pad were in contact with the aluminum chassis, but it is not. There is about 1.5 cm gap above the thermal pad and the actual chassis.
Moreover the board is mounted on a plastic frame (of course not conductive) glued to the top cover.
No thermal contact at all between the hot parts and the metal box !!!
Let's say that the thermal aspect has not been treated with the due diligence.
And the cpu Temperature shows clearly.

Thanks for the suggestion. But i see in many boards cpus and gpus having small passive heatsinks above them.
something like these ... in copper.

I wonder how much effective can be. For sure they are better than nothing.
And i have seen bare copper little plates like these ones here ...

I am going through all this work because as i said at the beginning i am impressed by the sound coming out from this unit. Honestly.
Very good indeed.
I guess a lot has to do with Windows 8.1 being better than 7 in this regard.
Thanks again, gino

Maybe a rectangular cut in the case and then a bigger radiator will solve the problem.

Hi i have actually done something similar.
I bought some low profile (5 mm) copper heatsinks adhesive on one side.
these ones here ... as a 1st try.

8x Copper Adhesive Heat Sink Cooler for CPU GPU PC Laptop RAM DDR Cool MC 200 | eBay

better than nothing i hope.
These heatsinks will go on the aluminum metal plate in the picture attached below
I will check the core Ts with CPUID HWMonitor that i have been told is quite reliable.
If i will be able to keep cpu cores Ts around 60 C it should be enough for system longevity, i hope.
Thanks again, gino

Hello .
Is the operating software embedded on chip and does it have a hard drive or can one be fitted?

thanks

Hi
the OS (i.e. Windows 8.1 Bing version) and all the SW is installed in a 32GB eMMC memory soldered to the board. Like the one here (this is not the Pipo. In the pipo is under the metal cover in the picture together with the cpu)
Click the image to open in full size.
There are also 2GB of RAM.
Of course is not very powerful (is not at all for 3D video games or HD video streaming), but for audio is very good. I like even the front headphone out's sound, just figure. The only ports are USB and one HDMI.
No memory slots at all.
Regards, gino

I liked the idea of putting linux on it to make a media pc.Can you over write the emmc memory?.
I like a fanless pc,I had a via one once with a low power 1ghz cpu that I played dvds and cds on.

Yes, something like Lubuntu 14.10 or if just for audio use then the Daphile.

I think in this case you just need some thermal pads. At my old workplace we had some extremely thick pads meant for use with power supplies, not easily available on ebay it seems.

So, get as thick thermal pads you can find, and find a block of metal - can be anything including a southbridge heatsink - sandwich the metal block between the two pads then sandwich that combination between the CPU and the chassis.
