Recently bought an A88m g/1.3 mobo and an AMD 7870K chip to build an HTPC. I have 4 chassis fans and one CPU fan. The CPU fan control works fine - speed is adjusted normally, however the 4 chassis fans always run at 100%. These are the chassis fans - http:// I found a review on a German website here (use google translate) http:// that says 3 pin fans always run at 100% on this motherboard, is that correct?
I bought this to be an HTPC, so fan noise is a big issue for this build. All 4 chassis fans running at 100% makes this almost as loud as a rack-mount server. I have adjusted BIOS fan settings and used A-Tune application, but the chassis fan speeds never change. I have already tried updating A-Tune, Mobo BIOS, and tried using software control through SpeedFan application but none are able to change the chassis fan speeds. I have the chassis fans connected to the two chassis fan 4 pin headers, each has a two way (4 pin) splitter to accommodate 4 fans off the 2 headers.
Any help here would be greatly appreciated, I really don't want to spend more money buying all 4-PIN fans but will if i have to as the noise level is unacceptable for use in the entertainment center.
