Pulsing/accelerating fan in T60

I have a new T60 that is exhibiting the seemingly well-known problem of the fan "pulsing" every few seconds. I thought this was an old and fixed firmware problem going all the way back to T4x models?

I've checked that I'm running the latest firmware. What gives? Anyone else having this problem?

Have you tried running the T43 fan control program? That might help. I use it while gaming or during sessions where the hard drive is accessing heavily to keep temperatures down.

Unfortunately that tool doesn't work in Vista

Wound anyone know where I can get a copy of the FAN CONTROLER program?

I think this utility was made for the T-43 which still may work with my T-60, since I'm running Windows XP...........

Thank one & all.

try NHC (and get an acpi file for it)

What a great little app!

Found an ACPI XML for Thinkpads and it's working very nicely - nice to have the granular control over all settings.

However.. the fan is still pulsing! I have disabled the Lenovo PMU services, but are there any other services/drivers shipped by Lenovo that control the fan speed?

There's no drivers or services you can disable. The fan is controlled by the Embedded Controller.

No response from two separate calls logged with Lenovo on this. Anyone else got any ideas, or any indication of whether this is normal?

Thanks

I had a T60 and don't recall the fan pulsing noise problem. On my T41 though, it's definitely present under certain conditions. What I did to alleviate it was to set CPU performance to 'adaptive' for the A/C setting in Thinkvantage power manager. This (in addition to the fact that I replaced a hot running Banias with a cooler Dothan CPU and used 'arctic silver' thermal compound) significantly reduces the CPU temps, and as a result the fan speed/noise. The CPU (1.8 Ghz) idles at 600Mhz now on A/C adapter. While this is not a good solution for a power user who is constandly maxing out CPU utilization, it works great for casual web browsing, email, etc. At 600Mhz I can barely hear the fan and 'Mobmeter' says my idle CPU temp is 44*C. It runs like this all day.
