Thinkpads Forum

Hello Everyone!

Three months ago I bought my first ever laptop-
Thinkpad W510 4389
i7-720QM
4GB DDR2
NVIDIA Quadro FX 880M +latest 1.45 BIOS, Win7 x64

As I know nothing about computers and my English is poor I`d like to ask You for some help regarding the Power manager settings and constant fan noise of a Thinkpad.

The PowM`s version is latest 6.65 plus the CPU`s power management is disabled by me because of the cpu`s whine/hiss.

Here are some screenshots of the settings in the Power Source Optimized Plan in use:





The machine is for these purposes: browsing with Mozilla (often more than 10 tabs opened),movies,using installed dictionaries,no gaming.

I would really appreciate any help and suggestions.

As soon as W510's have warmed up, the fan will keep running, usually above speed 2.

Making it stop or stay at speed 1, is not straight forward, we can't give you a ready made solution.
It requires testing and proper configuration of a fan control app, like TPFanControl, some hardware mods can also be done.

The GPU can also be forced to stay at it's minimum power state, but this may very well cause other problems.

Disabling CPU Power Management will limit the max CPU speed, in your case to 1.73GHz, rather then 2.8GHz.
It will also increase idle temps making the system even more noisy, but will lower max temps during most kinds of loads.

There is no simple solution to this problem.

The simple solution is to use Tpfancontrol. I wouldn't disable CPU power management, it helps the CPU stay cool at idle. The best way to go about it is set the CPU speed to adaptive, fan control to balance all parameters, CPU power management enabled, and use Tpfancontrol. Tpfancontrol is actually pretty easy to use.

I believe "optimize fan control" actually controls Intel's Dynamic Overlocking. If you have it set to "balance all parameters" it won't use turbo boost, if you have it on "maximize performance" it will use turbo boost. Since you disabled CPU power management I don't know what it does in that case.

These are the Tpfancontrol settings I try to use to keep my T410s in fan 1 mode, since fan 2 and up is loud.
