A few months ago I purchased a T7600 CPU to replace the T2600 on my T60p.

I kept hoping it would magically install itself, and nothing ever happened, so today I decided to tackle the project. It really wasn't a big deal although the assembly took quite a while when the cord to the power brick on my T61 (where I had the T60 HMM on the screen) sent my carefully arranged piles of screws all over creation when I moved the wrong way. Dragging a big magnet over and under the couch and the rug eventually came up with all the screws and four I didn't recognize.

This upgrade raised the Win7 "experience index" for both the processor and (surprisingly) the memory from 4.8 to 5.5. That really isn't earthshaking, but the machine does feel a little snappier and there was a definite improvement in my ability to logon via fingerprint reader while the disk is going berserk for the first couple minutes after booting - Symantec AV running hard along with several other processes. So I'm happy.

I'm really pleased that the air blowing out of the machine doesn't seem particularly hot; I didn't know what to expect given that I didn't purchase the bigger fan unit that some people have recommended for upgrades to the T7x00 processors.

Is there any tool available that would prove that things aren't running too hot? I wouldn't mind some quantitative proof of the temps being reasonable.

Is there any resale market for a T2600 CPU?

Interesting program, although it doesn't show any fan speeds!

I ran the Lenovo CPU diagnostic, and it certainly raised the temps to an alarming level. It shows four items, labeled Temp1, Temp2, Core 0 and Core 1. Temp1 never changed from 45 degrees C. Temp2 went as high as 95 degrees C. during the test, and returned to values between 53 and 61 degrees thereafter. The cores started in the upper 40s, went into the upper 60s during the test with bursts into the 80s, but are now sitting at 60 and 61 ten minutes after the test was complete.

I suppose anything under a hundred degrees C is acceptable, given the brief nature of the tests, but I would have hoped for a little better cooling performance. I had put a tiny dab of Arctic Silver on the CPU while leaving the existent thermal pads on the two video chips.
