Thinkpads Forum

After replacing the CPU from T2500 to T7200 CPU temperature ranges from 70-85C. It seems to me high, I think about replacing thermal grease or thermal paste application. What's better? Do away with the original gray ribbon and attach a new heatsink or better smear toothpaste?

If you reused the same thermal paste, it can be the cause. It is generally recommended to apply fresh thermal paste every time the heatsink is removed and reseated. I found it non-mandatory, but in some cases it may be. Also make sure the heatsink sits correctly and is level and all the screws are tight to ensure good contact.

Welcome to the forum!

As noted by dr_st, you really need a fresh application of thermal paste. I've done dozens of CPU upgrades using a very thin application of Arctic Silver 5 with great success. Going from a T2500 to a T7200 in a T60 should probably lower temps, not raise them. Good luck.

I undressed everything.
Termopad that is such a tape to the touch reminiscent of plasticine I'm only on the heatsink in place where contact with the graphics chipset and motherboard bridge. while in the place of contact with the processor heatsink does not have the tape and there was never.
So put on a new paste Zalman ZM-STG2 and max CPU temperature is 70C. between 68-70. That is decreased by about 10 degrees.

Generally, most heats up the CPU, VGA and chipset layout are cool. Tube heat sink from the CPU heats up quickly.

I do not know or is it better to give a paste 3M double-sided and best left as it is with the ZM-STG2??

What do you think about COOLLABORATORY products:

I am thinking if I use LIQUID METAL PAD CPU or LIQUID PRO will help better than ZALMAN ??
