T42 overheating because of slow fan speed

Anyone know what could be the reason behind this?

You know, when you start a Thinkpad up, the fan does a swift acceleration right before starting Windows. Well, my laptop doesn't do that anymore. It's (according to Thinkpad fan control tool) spinning around 2.8k all the time, and when I use CPU (or GPU) intensive programs, they are heating up to dangerous levels.

Also I tried to manually speed up the fan with the fan control tool, but it didn't do a thing? I mean, the program said that the command was ok, but the fan just kept running on the same speed.

If it's still under warranty, I would give a call to Lenovo support. It sounds like a hardware problem to me.

I did, it's in service now...Waiting with thumbs up

I was just asking if anyone else has had similar problems. I think it could be the fan, or the embedded controller.

Just got if from service...Now it's working again

It was the fan that was broken, at least they had changed it.
