Is there a way to monitor the fan speed for thinkpads ?

[nrj45]

This could be a good base to compare fan noise perhaps... I searched but didn't find any software that was able to show the fan rpm. I tried speedfan, motherboard monitor.

Do anybody have any idea ?

Thanks

I haven't found any either, but agree this would be a great way to measure relative noise levels.

If MBM doesn't support it, then the outlook isn't good.

I think a dB meter is best for this.

You'd have to specify the weighting, angle, distance, surface, environment, and meter to have anything comparable at all.

I'd settle for fan speed since the sound-making parts are all more or less the same for a given notebook size and model.

has anyone figured out if Lenovo is using different fans on the August 2005 T43 models? My 2686M7U (15") is quiet and I should be receiving a 2686M5U (14.1") next week so I'll post my results.

somehow, Lenovo managed to get rid of the annoying pitch of the first two T43's I tried, which makes me think they're using a fan with a different pitch at a slower rpm, or something along those lines.
