One of the Radiator fans making humming sound

Turtle Rig · April 17, 2019

This might go to the Air Cooling section, but I decided to post it here instead since it involves my AIO. One of my Rad fans makes a humming noise and is very annoying. Maybe people who are def might not hear it but it is soo obvious. All my other fans don't have this humming annoying sound. Should I buy a replacement or should I put the fan at 450rpm. At 450rpm it doesn't make that nasty humming noise. Anything higher and the hum begins. Thanks in advance.

So your radiator has 2 identical fans, but one makes the noise, but the other doesn't?

I would first try remounting the fan carefully, maybe try it outside of radiator, and if the noise is still there then RMA/buy a replacement, something wrong with the fan.

Yes per my signature. I have 2x Noctua fans identical for rad, and noctua for intake and exhaust. The fans barely make any noise, except for one of the Noctua fans just gives the humming when above 450rpm

But if you mount that humming fan to the front, do you still get that noise?

Also if it is noctua you should be able to get a free repair, as those are expensive fans.

Thank you Origama Cactus for your post. Yeah its weird I got back luck with one of my Noctua fans. The intake and exhaust make no humming noise nor does one of my fans on the Radiator,, Im going to see how the cooling is at 450rpm anything higher and the hum starts. Thanks again in advance.
