Windows 7: Mobo not controlling fan speed?

Mobo not controlling fan speed?

Hay, I bought a scythe fan for my case to go on the side, i've tried plugging the 3 pin connector into the PWR_FAN(3 pin) and CHASIS_FAN(4 pin), it gets detected in the bios and in speedfan, and various other software to monitor the fans.

Its running at 3,000 RPM which is way to loud for me, i've tried ASUS AI suite, amd overdrive, speedfan ect to try and turn down the RPM but none of them effect it, its going at 100% non stop and wont slow down no matter what, and even in the bios when i selected 'silent' mode it did not budge in speed at all.


Mobo: ASUS M4A87TD EVO AM3 AMD 870 SATA 6Gb/s USB 3.0 ATX AMD Motherboard
Fan: Scythe DFS123812-3000 "ULTRA KAZE" 120 x 38 mm Case Fan


Anything i can do to make this software or bios adjust the fan to the correct speeds? If i bought a hardware fan speed controller would that work?

I was looking at something simple like this: Newegg.com - Sunbeam PL-RS-PCI Rheosmart PCI 20W Fan Controller

But i'd rather not buy if my Mobo or some software can adjust the speed for me.

You can use speedfan to set the percentage speed to control the fan but speed fan must be open at for this work. Only fans with 4pins and mobo's with 4pin slots will utilize the built in fan controller....that's what the 4th pin is for. Other wise you will need a fan controller of some sort. I haven't used on myself but that one looks fine

I don't think you are going to get motherboard control of that fan's speed if it is not a "PWM" fan. A quick look at Newegg's spec doesn't mention PWM.

Newegg.com - Scythe DFS123812-3000 "ULTRA KAZE" 120 x 38 mm Case Fan

I've never used fan controllers, but they may work on it--or just get another Scythe that is PWM.
