“Corsair has now tracked down and fixed a rare and hard to reproduce issue on some of our Hydro series coolers, specifically the H60, H80, and H100 when used in combination with certain power supplies in certain circumstances. The failure will present itself as a buzz or hum, similar to a hard drive seek noise, and may disappear and reappear at random times. This issue affects a very small number of units, and typically is more prevalent on power supplies that provide higher than +12.2V on the +12V rail, which explains why some users have experienced multiple units with the same issue – they’re plugging them into the same power supply.

Regardless, this has since been corrected and we are now shipping units that do not experience the issue. If you’ve got a noisy H100, H80, or H60 unit, and the noise is coming from the pump (not the fans), we’d like to offer you a selective RMA. Please email us at RMAservice@corsair.com with the subject line “Hydro Series Buzz” and include your name, phone number, shipping address, and email address. We will contact you to start a replacement with a known good unit.

Thank you, and we appreciate your patience as we corrected this issue. “

The main question is how audiable should the pump be, its a noticable buzz I have, its not unbearable but definately noticable over the 7 case fans I have installed

Had my H100 a few days now and I am experiencing the same thing.

The noise is definitely coming from the pump and it is very audible, much more so than the fans. It sounds like a hard drive read/ write, but constant.

Any way to quieten the pump noise? Thanks.

edit: I should note that the cooling performance is fantastic. But the noise is doing my head in more and more!

Glad its not just me or my ears, sounds the same as me, im guessing the button only controls the fan speed and isnt anything to do with the pump then.

Again the same as you the performance is great, ive managed a 5ghz stable overclock on my i7 2600k which I couldnt do before, although it needed around 1.5v which isnt great for 24/7 having said that load temps didnt seem to go above 68C and thats using the stock compound.

No its not just your ears, i have had all the fans off completely to isolate the noise, and I can confirm it is the pump (the main head unit).

I have 4.1 ghz on my i5 750 with a vcore 1.37. With this cooler with fans set to low i get avg temps of 42 C. Med setting and i get high 30's - excellent. The fan noise on balanced is perfectly acceptable to me.

I am using the stock corsair fans to "push" air onto the radiator and out the top of my Fractal Arc Midi. I am so pleased with the performance I am not going to bother getting additional fans for push/pull.

But that damn noise.. I hope there is a solution I really don't want to return the H100.

I have the same problem on the H80. Im pretty sure it wasn't like this when I installed it. It was fine for a week and now its making this noise, as you describe, like a constant hdd read/write.

Out of interest if you turn your case around 30 degrees or so is the clicking less audible?
Mine is better with the case on its side but of course I cant leave it like that.

RAM GUY · #7 08-15-2011, 02:56 PM

Are you sure its not just some air trapped in the pump, have you tried moving the system around while its running?

That's interesting, if I lay my case on its side the noise is still there, but certainly quieter. Using the constant hdd read/write sound analogy again, with the case on its side, the sound appears slower and somewhat quieter, albeit still audio-able over the fans on balanced.

Confused

It may just be some air in the pump then and should work it self out over the next few days.

I have just 'cradled' my case like a baby and swayed it back on forth a few times (with the system running). It hasn't made any difference.

Does that mean it is not air in the pump? For your information the sound is very consistent.

Thanks.

RAM GUY · #11 08-15-2011, 03:10 PM

If you lay it on its side and the sound changes then it is likely some air but I would give it a few days and see if it subsides if not then you can always request an RMA and we can replace it. but the pump will not be totally quiet but should not be so loud you hear it over the other fans in your system.

Thanks - i understand the pump won't be totally silent but at the moment it is very much louder than the fans! I am happy to give it a couple of days and report back.

Thanks again.

I ran mine on its side for an hour or so over the weekend but the noise is still there. Maybe I'll take the cooler out and give it a few gentle sways.

One thing to check is to make sure all your fans are tightened down well.
I've seen/heard a very slightly loose fan make a vibration and thus produce a buzzing type of sound, many a time!

Make sure all your screws are nice and snug

That's a good point but sadly that is not the issue with mine. To test the theory I have turned off all of the case fans and the H100 fans keeping just the pump on. The noise was still there, coming straight from the head unit.
