Flashing red led and loud CPU fan

I bought a refurb mobo on newegg: https://www.newegg.ca/Product/Product.a ... 9BS6JX1679

All of the I/O appears to be working (I'm typing on it now) except the CPU fan is VERY loud and there is a led is flashing red.

Is this a "bad" motherboard or just a really noisy CPU fan (it's a Cooler Master Hyper T2 CPU Cooler)?

SOLUTION: Configured CPU FAN is BIOS settings

1. if you are not having any stability problems with it, then it's working fine. have you run any stability tests on the new board?
2. by "power LED", do you mean the LED that's on the case? have you connected the the PWR LED and HDD LED cables from the front panel of the case to the correct corresponding positions on the motherboard?
3. as for the CPU fan, the first thing is to check the fan profile settings in the BIOS. did you also buy the CPU fan recently?

1. Not sure what to run.
2. I think it's the HDD led... oops.
3. Yes, it's a brand new Cooler master and noisy AF. I didn't realize I could configure the CPU fan.

Went into BIOS and set min speed to 0%.

It's running very quietly now. Thanks a lot for the help.

try AIDA64 for stability test. you can stress the CPU, memory, and GPU (is you have one) simultaneously.
