T400 thermopad thickness

[JAJO]

Hello.

I would like to change this a little part of thermpad.

I've bought Phobya Thermopad 1mm thicknes.

How do U think, does it enough or should I buy thiner?

Thx for help.

That should be "OK" but there are a lot of variables. The cooper heatsink for example can be easily and accidentally twisted and bent out of shape. The best way is to use the old overclocker's method of stress testing and monitoring temp after a change. If temps are better after the change, then it's great, stay the same is OK, while higher temp is not OK.

I've installed before 1,5 mm thermopad and the temp. was a little to high.

After installing 1 mm thermopad the GPU temp R about 80 *C and CPU about 90 *C in high stress and fans start working.

In normal work the CPU is about 65 *C and GPU 70 *C. In my opinion it is a little to high.

I don't remember what was the temp. before changing thermopad cause I changed CPU too (from P8600 to P9600) and used Arctic Silver 5 thermal paste on both CPU and GPU.

What do U think about that all?
Is there any support site where is written how high should be thermopad for T400 with GPU?

Those temps seem too high. I use paste.

I used paste too, Arctic Silver 5, which is good, I think so. When the temp. R really high my cooling system always cool CPU/GPU to lower temp.

Those temp. R when I switch to High Performance mode and I'm in warm room. When I switch to Energy Saving the CPU temp is max 55 *C and in stress maybe 65 *C. The GPU is in this mode turned off so it shouldn't generate any heat.

I read all temp. from TPFanControl. What software R U using?

Don't use paste with a pad. Every layer transfers heat with less than 100% efficiency
