Thermal mod and temps

[Pigman Rocker]

i have done it with 1 shim and some thermal padding my temps are almost never above 60 degree its a must if you ask me

The processor gets 62 degrees celcius and a single score: 2378 and multicore: 4531.

I was using google docs at the same time.

I personally think it’s the ‘optimized’ bios as since I’ve flashed it I find the tablet slower, benchmarks are also down a little and boot up time is increased by 30-40%.  I’m looking for a way to go back to the original bios if you have any ideas.  I’m not sure how you used heat pads to stick the copper shims on as it would be way to thick, I just used 6 1mm copper shims, thermal paste one side and thermal adhesive the other.  Haven’t checked my temps since flashing the bios as for me it has totally ruined my tablet and I hate it 🙁

I used this http://arvutitark.ee/prodpics/31/31870/original/39628.jpg which is just 0.3mm thick. I think the original pad sitting on top of the heatsink was 1mm thick so my 1mm copper shims + the thermal sticker aren’t much different in thickness. I did not however put any paste on top of these coper shims, maybe this was a mistake?

Anyways, I find the performance on the newest optimized bios to be good even though I really think XTU does not work for me at all. I think I’ve seen around 160fps in Legend of Grimrock when I pulled all the settings to low leaving the res at 1920×1200.

I think I might downgrade bios to the stock one once I find out how to do it properly just to see whether this makes any difference at all.

No issues with the custom bios on my device.

And even with the slightly lower performance due to throttling, things liked the fixed pwm frequency outweighs this.

Edit: seems like the custom bios is by default at 7W, so there shouldn’t be any throttling if the temp is <80°C, otherwise it will throttle to keep the temp at max. 80°C

Hi Chris,

Did anyone ever attempt to replace the aluminum stock heatsink with a copper one, like it can be seen here:

I was trying to do this full copper heatsink mod, but I cant get the schematics to print out correctly, since the DPI number that Wootever gave seems to be wrong…

Anyone ever did that mod and can help me??

[BoORD_L]

have a look on 4pda.

What I've used and what I've got:
TECLAST X98 AIR 3G, TECLAST X98 AIR II, TECLAST X98 PRO,CHUWI HI8, CHUWI HI12, CUBE I9

Can you post a pick or can you explain better???

You putted 6 cooper shim around the heatsink? Have you covered the entire heatsink?
