Controlling fan RPM?

[Thors.Hammer]

I currently have TPFanControl installed on my X301 and have been experimenting.

By default the X301 fan runs at about 5000rpm. Thankfully the fan design on the X310 is unique so 5000rpm isn't as bad as you might think from a noise level.

If I set tpfancontrol on manual with a setting of 2, it runs at about 4500rpm and keeps the temp at 47C.

If I set manual to 1, it knocks the fan speed down to about 1800rpm but heats up to 58-59C.

Is it possible to specify something in between? I would like to run the fan at 3500-4000rpm. Do any of the tools allow you to set the RPM?

Not posting a solution, but why does it run so hot at 1800RPM? I just tested mine by setting it to BIOS, which causes it to run around 1800RPM and it only brings my temps up to 46-49C.

Are you using a X301?

yeah I have an old one that I just booted up. It is running Windows XP though...

On two of the desktop machines that I built, I use SpeedFan that offers minute control of fan speeds vs. CPU temperatures. It's only because I was being cheap and bought Foxconn mobos that have very rudimentary BIOS. Anyway, I set up SpeedFan as a scheduled process that runs right after the desktop appears.

It is running Windows XP though...

If XP runs cooler, then I guess Linux runs ice-cold.

Thanks. I will look into it and see if it handles what I want to do.

I doubt Speedfan is compatible with Thinkpads though. I use to LOVE Speedfan until I started to get newer laptops which didn't have support.

yup I should try Linux since I never use this laptop anymore. It's the U9400 CPU with Windows XP.. also I told a fib, I have it undervolted too.

That might be one reason for the difference in temps at certain fan levels.

Might as well undervolt anything you can. Only benefits, no drawbacks.

[not.sure]

At some point I was (under Linux) fiddling with PWM to control the fan. Not sure any more whether that worked...
