Suspiciously low temps

[vinuneuro]

Just ran tpfancontrol on my new to me T60 and the temps being read out seem unusually low, enough for me to wonder if I've done something wrong with the software. T60 w/ X1400, tpfancontrol 0.18. The laptop is completely stock/unmodded, bios mode.

Idle:

CPU: 43*C
GPU: 46*C
3435 RPM

These may be normal temps on idle, depending on the environment temperature.

Talk about looking a gift horse in the mouth!!!

Seriously, though, these temperatures are fine. At idle, neither the CPU or the GPU are doing much of anything so the temps should be in this range. I think many T60's have some dust clogging up the works and Lenovo didn't appear to build much reserve capacity in the T60 cooling system, hence the many reports of overheating.

But they advertised the T60 as our "coolest laptop ever".

My T60 cpu idles at about 53 degrees... and it's just 1.66Ghz with integrated graphics.

Although the T43 was reputed to be hot, oddly enough my T43 with X300 dedicated GPU is the coolest among the T-series laptops that I currently have. It's typically in the 40's and usually stays below 60 even under heavy load. But always loud fan noise!

They did? Can't trust anyone any more!

I have year old T60 with same GPU. My temperatures used to be around the same, 43C for CPU and 45C for GPU, 3000RPM and ~22 ambient.

I think your and my T60 have different heatsink than other/older ones that were reported to have very high GPU temp. I think the difference is that the heatsink has better connection between GPU and CPU parts or it has better contact with GPU, because other temperature follows the higher one very closely. People who reported high temperatures had high temp only in GPU, like it didn't affect CPU temp at all. At least this is what I concluded and remember.

Recently I noticed my temps had suddenly rose to 51C CPU and 52C GPU, probably because I once screwed out heatsink and it lost some contact.

If you enable ATI powerplay you can probably cut down a couple degrees.
