Tool for Linux to manipulate the fan on Thinkpad?

I'm trying to locate a program that adjust / manipulate the fan on my thinkpad.
I know this is possible for Dells laptops, but there doesn't seem to be a Thinkpad alternative.

The only thing I can do is to watch what temperature the CPU has for the moment.
It would be cool to be able to lower the temperature manually through gkrell.

Fan control is part of the IBM-ACPI, listed as being part of the 2.6.10 kernel.

Can I manipulate the fan via Gkrellm?

If you install the lm_sensors package, the fancontrol utility (for automatic control based on CPU temperature) is included. You can adjust the temperature thresholds as part of the configuration with pwmconfig.

That seems to be much work, just to be able to control the fan.
Why use I2C for lm sensors?

Anyway, the IBM-ACPI that comes with 2.6.10 kernel doesn't contain all the features for some reason.

Shouldn't there be more tools to use?
The tools I'm refering to are the experimental drivers.
