me9atr0n Posted November 15, 2015 Share Posted November 15, 2015 I have a brand new Corsair H100i GTX making an annoying rattle. Doesn't seem to be the fans, definitely coming from the pump. I made a short video, you can hear the sound get louder the closer I get to the pump. Is this a case for RMA? **edit** I originally thought this was in Quiet Mode, but after figuring out the Corsair Link software, this is in fact Performance Mode. It is dead silent in Quiet Mode, the noise only happens in Performance Mode. However, should I be alarmed about this noise that it makes in Performance Mode?

kakisgr Posted November 16, 2015 Share Posted November 16, 2015 I have the same problem when the 3pin is connected to the CPU_FAN try the CPU_OPT but check your motherboard manual first. Link to comment Share on other sites More sharing options...
me9atr0n Posted November 16, 2015 Author Share Posted November 16, 2015 Ok, I'll give that a try. Am I correct in assuming that I should disable any speed throttling on the pump header? Like Asus Q Fan control? Also, should I be powering the 2 fans with the cables coming out of the pump? Or would it be better to plug them into motherboard headers?

red-ray Posted November 16, 2015 Share Posted November 16, 2015 Yes, you should disable Q Fan control. The optimal setup seems to vary depending on which motherboard you have, so add your PC specs to your profile. Link to comment Share on other sites More sharing options...
me9atr0n Posted November 17, 2015 Author Share Posted November 17, 2015 Ok, I have updated my pc specs. Most importantly, my motherboard is an Asus Z97-Pro. I have tried switching the pump cable to the CPU_OPT header, and it still makes the same noise. But now I notice that in the Corsair Link software, it only shows that one of the 2 radiator fans are spinning, even though they both definitely are, so in that regard it was working better before, while plugged into the CPU_FAN header. While doing other troubleshooting steps, I unplugged all fans to eliminate any other noise sources, and the rattle still remains from the pump. This can't be how this is supposed to sound, I would expect that a liquid cooling system on "quiet" mode should be completely silent. Should I just assume that this one is defective and get an RMA? Will they ship me a new one before I send the broken one back, so I don't have to be without a CPU cooler? Link to comment Share on other sites More sharing options...
Corsair Employee Corsair Dustin Posted November 17, 2015 Corsair Employee Share Posted November 17, 2015 You can get an advance RMA; you put a credit card on file with us, we send you a replacement, then you send your broken one back. Link to comment Share on other sites More sharing options...
me9atr0n Posted November 17, 2015 Author Share Posted November 17, 2015 Wow, so I feel really dumb. I just didn't know how to use the Corsair Link software properly. I was clicking the task tray icon and selecting Quiet Mode there, thinking that was putting my whole system in Quiet Mode. But I noticed that my pump was constantly running at 2900 RPM, never changing. So it turns out that selecting Quiet Mode on the task tray icon only changes the speed of the 2 radiator fans. Now I see that you have to click on the pump and go to configuration and select Quiet specifically for the pump, which dropped the RPM to around 1800, and shut that rattle sound up completely. Now I can't hear a thing! So my question now, is that a normal sound for Performance mode? Should I be worried about any potential failures?

0nur Posted November 18, 2015 Share Posted November 18, 2015 I have same problem with you. Quiet mode is silent but when I set performance mod, there is same noise. I can't make sure about it is defect or not. [ame= ] [/ame] Link to comment Share on other sites More sharing options...
Corsair Employee Corsair Dustin Posted November 19, 2015 Corsair Employee Share Posted November 19, 2015 So unfortunately some of the coolers are a little noisier than others. If Quiet mode gets rid of the pump noise and you're comfortable with that, go for it. However, if you're not, you can always contact our customer service department.

me9atr0n Posted November 19, 2015 Author Share Posted November 19, 2015 Ok, thank you for the responses. I'm going to try it for a few weeks and see if I have any more issues. Just wondering, is there a chance that older H100i GTX's would have had issues that were cleared up on newer revisions of H100i GTX's? Because I bought this cooler from Best Buy, and I assume that they don't sell very many of these, so maybe it could have been sitting on a shelf for a very long time. I'd hate to RMA it if this is normal, and a replacement does the same thing. But judging from the videos I've seen on youtube, mine seems to sound worse, it's definitely annoying in person.

Corsair Employee Corsair Dustin Posted November 20, 2015 Corsair Employee Share Posted November 20, 2015 Older H100i GTX's were definitely more prone to noise than newer ones. You're welcome to see if a replacement fixes the issue for you, just contact our customer service department. Link to comment Share on other sites More sharing options...
