Corsair H80i Pump Whine

[AirwavesNM]

I've had this cooler installed since I built my PC around a year ago but the other day I decided to swap the fans that came with the unit for the new SP120 green ones (as it's a green build) and I wanted those as the finishing touch.

 

I'm starting to wish i hadn't. Since I installed them onto the unit and fixed it back into place the pump emits a high pitch whistling sound. I did stop both fans it see if it was the bearings on one of those but it's definitely the pump.

 

Any ideas guys? I can still hear the noise now even though my PC has been off for about an hour.

Ummm.... what? If it's off, it should be off.

swap the stockers back and see if the noise persists

as speed said,if it were truly off no noise could be emitted

try unplugging the hydro to isolate the noise origin...

By me saying I can still hear it I meant that it's a high pitched noise that stays with you. Much like when you attend a rave or nightclub and you can still hear the beat of the music in your ears when you get home :p:

 

In any event it's cured. It wasn't the fans themselves just when they were mounted to the radiator, I have no idea why. I had thought perhaps the increased airflow produced a whistle as the air went through the radiator fins?

 

I now have the original fans mounted like before and it works fine. If Corsair ever bring out green Quiet Editions (why the tell have they not) I might get those and try it again but for now my ear are enjoying the silence!
