How to control fan speed?

[marshal11]

i have just bought a new case fan, it is PWM and the RPMs are 600-2000. i want to know if there is a way to control the fan speed because every 3pin/PWM speeds it up to 100% and it is very loud at this speed. how can i control this without a fan controller, or do i need one? can i do it right from my UEFI BIOS when my computer is done? (my computer is not done, i still need a SSD, HDD, and the CPU.)

i have a MSI Z77 GD55 by the way, i have still yet to see the BIOS, i'm currently using a 7 year old ASUS pentium D extreme set up (originally was a pentium 4) and i can't do anything in there. i can't even OC. forget changing fan speeds either.

I had the same problem. I use two programs.
One I downloaded from my Mobo website: ASRock EXTU.

Also I downloaded a program that any platform can use: Speedfan

http://www.softpedia.com/get/System/System-Info/SpeedFan.shtml

They have a setting that allows me to reduce my Sys, FPU, Aux: I reduce
those to 50% (not gaming) and Check "automatic fan speed" That keeps my
fans running at around 1200rpm, not 2000 (full auto)

I highly suggest this program. Try this first.

your case came with PMW fans? what case is this?

?? you should read the first sentence again.

ah my mistake. can't return the fan?

no unfortunately, I baught it at my local store and I don't think they will take back anything already opened. what is the difference between a PWM fan and a 3 pin fan anyway?

and moles fans are just uncontrolable without a fan controller correct?
