I want to increase the rpm of cpu fan. currently it is running @ 1800 rpm
is there any way to increase the fan speed so that cpu temp can decrease?

its automatic on any modern system and looks after its self (pwm etc)

your cpu should run under 60ºc which is fine - no need to worry

The automatic fan control usually don't works very well. In the BIOS you can find the option for rise the fan at 50%, 60%, 80% or 100% all the time.

It also depends on the max rpms of your fans.
Increasing the fan speed from my experience doesn't drop the temps that much.
Maybe only 2 or 3 degrees C max.

I've seen better results by switching the thermal paste.

A combination of the 2 will noticeably drop your temps.

Or a better heatsink.

I have changed the setting in BIOS for my CPU fan to aim for 40 degrees all the time, and set the min speed to 87.5% but still it sits at around 2050 RPM all the time - it is supposed to have a max speed of 2500 :/ 

Its Arctic Cooling freezer pro 7 rev 2.

My i5 750 @4GHz CPU is usually 38-43 degrees at very low load/idle and at the other end it hits 75 in intel burn test on maximum.

Any ideas why I'm stuck at 2050?

Sorry for thread necro but I figured if a similar thread already existed why make another :/
