Woah! H100i Pump Noise

Hello all,

I recently purchased an H100i figuring the pump issues were worked out O_O, everything installed fine and temps are good. I noticed there was a Corsair adapter for the fans to plug into the pump. It turns out that when the fans are running off the pumps SATA power connection I hear pump noise and it does not go away no matter position etc. I have tested this and it is running quietly now when my fans run off motherboard 3-4 pin connectors. Seems as though running the fans on the same power source as the pump has some kind of power draw that is causing the issue. I'm not sure whether this is the same issue the other poster had below me but I have found a temporary workaround for the issue at least for me that I thought I would share.

We thought Corsair has solved the pump noise problem. Sad to see it is rearing its head again in H100i

I believe the H100 had this problem when not getting enough power as well? I don't know why this has not been fixed yet. You'd figure the second iteration would've went through QA testing for this. It's not a total deal breaker cause I can bypass the issue but it basically means I can't run the fans off the pump or control them via corsair link commander.

echosky - any chance you can provide a video? I'd like to check it out and see if I can isolate the sound.

I will try and put up a YouTube link later. It sounded like the noise was coming from the radiator though near the tubing connectors.

Here's the YouTube link RAMGUY. I also noticed that the noise occurs once any fan is connected either one or two onto the pump block. It is definitely not as noticeable with one fan connected, but once both are connected it gets louder. I have also tried supplying the the pump connector with a dedicated SATA power cable with no other devices feeding off it but it did not make any difference. Hope this helps.

What you suggested works... it's a shame that the H100i didn't include fan cable splitters.

I'm glad you tested it on your unit as well, that confirms it happens on two separate H100is. Hopefully it is not a widespread issue.

I am afraid that it might actually be a widespread issue--for this first batch of H100i anyways. My replacement H100i has the same issue and producing the same type of noise right this moment.

I have the same issue, the noise definitly come from the fans when they aren't at full speed (that explains why it doesn't happen when the fans are plugged on the motherboard). Once they slow down, there is a sort of "vibrating" noise very annoying, if I stop the blades with my finger, it continues for several seconds before stopping.

Installed mine and can confirm same issue. Pump silent, fans noisy. This is the same issue i complained about months ago using the Link. If Corsairs fans are not running at full speed they make a light "grinding" noise.

Seeing the above it would be prudent to revert back to older type of fans with 7 static pressure.

Yeah it sucks because the Corsair Link program has much better fan control than speedfan or some random HW monitor :/. Idk how they could fix this though considering the product is already shipping.

Same issue with mine. The pump is silent...but the fans plugged into the H100i make a grinding noise. Unplug the fans from the H100i and onto motherboard headers, all good regardless of speed. Not sure what to make of it. Also, back cpu bracket had one of the screw holes with bad thread. Couldn't use it at all. Simply used the bracket from my H100 which works fine. Where's the quality control Corsair?
