T42 overheating problem

[t6bras]

T42 type 2373-9xg
P M 1.8GHz
ATI Radeon 9600

The fan is working at the same speed all the time. I have tried to manually change the speeds with tpfancontrol but nothing works. The speed used to be 2800rpm before i cleaned the fan and heatsink, after that it is around 2200. CPU is idleing at 50+ degrees. For example if i run 3dmark 2001 the CPU will go up to 86 and GPU will go to 91. Usually the system will just shut itself down after the heat gets too high.

Are there any ways to repair the fan or do i need to buy a new one?

Welcome to the forum!

I'd get a M10 long fan, and apply AS again, to see how that works...

Good luck.

I'm a total newbie to TPs and TPFanControl, but did you go into the INI file and change the default 'levels' - these let you set what fan speed to use at what temperature threshhold?

The default settings are very high (60-85 C / 140-185 F) and are for a T61.

Download one of the earlier versions, 0.25 or 0.33 which were made for T43/p and you should be OK. I couldn't even get the fan started on my T43p with the latest one...

Did you tighten the screws enough, and did you tighten the screws in the correct order? It could be that the cooling assembly isn't touching the CPU/GPU.

I'll try different versions of TPFanControl, maybe one of them works. Don't remember the exact version i had.

Most likely you need a new fan. I just got my T42P back from service, same symptoms that you had, system just sitting there will be around 65 and goes up to the mid 80s when I watch a video. IBM / Lenovo service replaced the fan and now the starting temp is just around 50 to start.
