T43/T43p fan noise vs T42/T42p fan noise

[wiesl]

Hello!

There are a lot topics about fan noise in the T43 series.

I want to buy a T43p UC3G2AT. I was at a thinkpad center and made some CPU benchmarks (100% CPU usage for about 10 minutes) on the machines but couldn't see any loud noise on both the T42 and T43 series.

As far as it was told to me the BIOS was up2date.

Are there any differences with latest BIOS updates?

Ciao,
Wiesl

You won't notice it if you are somewhere in public. But... as soon as you get in a classroom, library or work with the lappy in the evening in a quite room, it'll drive u nuts. I have the notebook for more than 3 weeks and I can't get used to the noise. I have contacted the author of CHC and offered help, but he is on vacations for the next 2 weeks... anyway it seems he is aware of such problems and is working in this direction.

like, trying to get CHC to control thinkpad's fan? That would be awesome. Dell and Toshiba laptop users can control their fans for ages.

Pardon my ignorance but what is "CHC"?

CHC is "Centrino Hardware Control," a free utility that can be used to undervolt a Pentium M processor.

You can get it here:

It seems to work well for most people, but it is freeware and there are no guarantees.
