W520 high CPU temperature

The temperature of my W520 reads at 59+ C at all times and the fan speed is always high at 2,915 RPM. When I installed the TPFC, the smart option would keep the temp at 71 degrees and the fan speed at 2,175 RPM. The temp seems high to me compare to the other info I've read on this forum. A youtube video in HD takes the temp up to 70 with BIOS setting on the fan control and raises the speed of fan up to 3,555 RPM. 

 

I have 24 GB of RAM and a docking station with two additional displays hooked up. 

 

What additional info do you need to give some clue on the this issue?

Re: W520 high CPU temperature

what if you disconnect the two additional displays? also have you tried cleaning the heat vent and fan?

Re: W520 high CPU temperature

It does not make a big difference. Only 3~4 degress!

Re: W520 high CPU temperature

Do you have the 1000M or 2000M?

When did you last repaste/clean out the fan?

Re: W520 high CPU temperature

Thanks for the reply. I have 1000M. I have not repaced or replaced the fan yet, although Lenovo has sent me one to replace. i did not want to send my laptop so I asked them to ship it to me. Is it too complicated to replace it?

Re: W520 high CPU temperature

It's not too difficult on the W520. You can follow the W520 HMM to replace the heatsink yourself.

 

Usually, there's nothing wrong with the existing heatsink, but rather the vents may be packed with dust.

Re: W520 high CPU temperature

What should be the normal temp on W520?

Re: W520 high CPU temperature

Mine is running around 40C on the CPU right now. I don't have the discrete graphics card active though.

Re: W520 high CPU temperature

You could also send it to a local PC shop have them repaste the heatsink and clean the fan if you dont have enough experience. They love to maintain ThinkPads because it's so easy.
