Cool 'N' Quiet not working on new MSI board

I just installed a MSI 785GT-E63 motherboard in my first build (While still using some original components from a HP OEM). Almost everything works like it should, but I'm having trouble with the CPU fan always spinning at 100%. I want to slow it down.

Here are my specs:

  1. Rosewill Challenger case
  2. AMD Athlon X2 5600+ Winsdor 2.8GHz stock (OC'ed to 3.08GHz using the built-in overclock switch on motherboard set at 10% increase of FSB [200MHz to 220MHz].
  3. Stock OEM CPU cooler
  4. New MSI 785GT-E63 motherboard
  5. 3GB DDR2 PC-5300 RAM (2X1GB and 2X512MB)
  6. BFG GTX 260 Core 216 overclocked
  7. Existing version of Windows 7 64-bit


I went into BIOS to enable the AMD Cool 'N' Quiet thinking it would lower the fan RPM's abit. I toyed around with the hardware monitor Smart-Fan settings as well. No luck, the fan is still at its peak RPM range. Upon the first boot into my existing Windows 7 OS, I noticed that windows began installing the different chipset drivers of sorts. After this process finished, I decided to reboot Windows. There's no change.

I then tried the software-method with Speedfan and AMD OverDrive. Those did not work either. Speedfan detects the fan, and the RPM's but I can't alter the CPU fan speed. Same goes for OverDrive, moving the sliders has no effect.

I'm stumped... and this noise is irritating me.

Note: The CPU fan is a 4-pin, same as the motherboard input.

First, make sure you plugged it into the proper fan header on the motherboard. Then, check the BIOS for something like "Smart fan control" and make sure it is enabled. If it still is spinning at 100%, maybe something is wrong with the motherboard or fan...quite unlikely, though.

I re-checked the fan header. Fan=4pin mobo=4pin... And I also have the SmartFan feature enabled in the BIOS. There's still no changes to the fan speed what so ever.

I checked to see if there was perhaps a BIOS update that I could do... unfortunately, my board came shipped with the latest version already. I checked the CPU support list on MSI's page, and what I found was rather interesting.

I see that the 5600+ Brisbane 65W is supported... but no Winsdor 89W?

Could it be... since Winsdor is not on the official list which means that my CPU is not supported, hence I can't control my fan settings?

I don't have much experience with MSI boards other than two old Intel/Compaq/MSI boards from 7 years ago or so, and I also didn't quite make much use of the fan control on my NF750-G55 before it broke, but it did fine with the little use that I did.

Back to this, I think that it should be working fine even though the CPU isn't listed. Maybe the mobo is (somehow) broken? My NF750-G55's CPU fan header broke in such a way that fans hardly spin or don't start at all. I don't know what to say.

Keep in mind, when I said to check that it was in the proper fan header, I meant to make sure it wasn't one of those constant +12v ports, though if it's 4-pin it probably isn't.

Wow, I must be a derp of some sort. After looking over my CPU fan cable for a more closer examination, I find out that it is a 3-pin connector instead of the 4-pin pwm connector which I thought it was in the first place.

I feel ashamed... :D
