i just think that fan pulsing issue maybe needs new thread here because some major problems pointed here http://forums.lenovo.com/t5/X-Series-ThinkPad-Laptops/X220-fan-constantly-on-revving-up-and-down/td-... are with new bios (1.16) solved.
So, as many user may experience - thinkpad x220i (i3), but also other x220 series have this fan pulsing problem. If you put your ear at the fan area you could notice every 3-4 sec some sort of pulsing/beating. This pulsing is gone between 1954-1972 RPMs by my x220, but at all other RPMs i can hear it, or even feall it with my hand on keyboard.
I uploaded the sound of this pulsing fan here:
You can hear it with headphones an 100% Volume. Hopefully we get this problem solved...
Solved! Go to Solution.
