Cooler Master Seidon 120V Buzzing

[Magnet_man16]

Attached is the sound. I have just downsized from a full sized corsair 750D case to the 400c. In doing this I bought some new case fans however my gigabyte motherboard (gigabyte ga-970a-ud3p) only has two PWM headers.

 

I used to plug the pump into a PWM header, even though it only requires 3 pins, to avoid this noise its made since purchase. However now I dont have any (Already splitting both 4 pins already) Its making the attached buzzing noise. Constantly. 

 

It seems to only do it at 12v, which is strange as this was the voltage it was designed for.

 

Anyone have any solutions? I can't find anywhere in the bios to lower the voltage on the SYS_FAN2 header. My previous Asrock motherboard allowed this...

It's probably just the pump. If it really bothers you either RMA it (if you can) or replace it.

Right. Oh its started twittering now. Really doesnt like the 12v one bit. Might leave one fan unplugged and put it back on a PWM header. Doubt it will get RMA'd as its over 2 years old now.

Got up this morning. Turned on PC and it shut it's self down after a minute.

 

RIP Pump. It's reporting 0RPM in the BIOS and when I touch it there's no vibration.

 

It's dead Jim...
