New Thermalright MUX-120 Black and Getting CPU Fan Error on boot up?

post #1 of 6
Thread Starter 
I decided I would oc my new i5 system. After installing my new Mux-120 I seem to be getting a CPU fan error on boot up. I can push F1 to continue and the pc loads fine. My idle temps at stock mhz are about 22C and at full load 45C so I think my cooling is fine. I do see the cpu fan running also.

I also had a stable oc to about 3.5mhz with max temps on prime of 51C after 6 hrs, but Ive gone back to stock settings until I figure out if this CPU fan error is serious...

Any ideas?

There are 3 wires usually on the connector, one of them is the speed sensor wire. make sure you have your CPU fan plugged into the connector on the board that is specifically meant for the CPU fan. The mobo should say CPU FAN next to the plug.

edit: i'm very close to being able to sell my gear in the marketplace. I need 3 more reps!

I checked the fan cable from the MUX-120 Fan, it has 4 wires. I have it connected to the motherboard on a 4 pin connector labeled "CPU fan".

Still getting fan error F1 to continue on boot up...

Did you try resetting your BIOS? Unplug and remove the battery for like 5 min also could use the reset jumper.

check your BIOS if the CPU Fan is set PWM fan, not DC Fan, or your fan speed might be too low at start-up.
If non of the above, set your fan speed IGNORE(BIOS).
