One of my fans is driving me nuts

post #1 of 13
Thread Starter 
Hey guys, I have a Gigabyte z77x-ud5h motherboard in a HAF 912 case with a Hyper 212 Evo in it. Basically, my problem is that my back case fan (System Fan 3) is always loud and goes non-stop at 1200 rpm. I unplugged the fan to test it and noticed how dramatically quieter it is with it off. I have tried messing with the Bios settings setting the case fans to "Quiet Mode." It has done nothing. Easy Tune 6 has not helped at all either. Also, Speedfan does not seem to be compatible with this. This problem is driving me nuts! Any suggestions you guys can make?

In order to control fan speeds in speedfan go to configure>advanced>IT8728F at $A30 on ISA (or something similar, probably same since your board is almost the same as mine) then set the PWM 1, 2, 3 etc to software controlled or on/off. Then you can control the speeds and set percentages on the main window.

Just spit coffee on over my keyboard! biggrin.gif

What are your other fans driving? thinking.gifthumbsupsmiley.png

What fan model is on the back?

In all honesty you could get a fan controller installed, they are relatively cheap and being able to crank the fans down to their lowest settings when your just browsing the web and want some quiet time is brilliant smile.gif

If you can and/or have money for it replace the CPU and case fans

I only have the fans that came with the HAF 912 installed. Both are 3 pin. So I might just have to get a 4 pin 120mm case fan.

Loud? Umm ... i think what you have there is ... your ears are a bit OVER-sensitive or it's a dud, maybe because it's high-pitched. Because CM's fans are usually very silent apart from H212's fans of course
I mean i use 34db deltas and they don't even bother me because they are very low-pitched and i have very sensitive ears as of now ... the fan i have on my HSF is quiet but extremely noisy because it emits coil whine that people can't hear apart from me

I'm pretty sure the reason it's loud is that it is constantly running at 100%. Not that my ears are oversensitive. The fan on the front of my case isn't loud at all and it's the same fan just running at a much lower RPM.

You are talking about the stock 12cm fans? Those are almost dead silent. There must be something wrong with the fan if it's that load.

You could buy a cheap fan controller and hook all the fans up to that if you dont want to replace the fans
