Corsair H60 Noisy in Push / Pull

post #1 of 3
Thread Starter 
Greetings,

I'm finishing the setup of a new system for a friend of mine. For CPU cooling, I've installed a Corsair H60 with two Scythe S-Flex SFF21G in push / pull configuration. The problem is that when both of the fans are running at rated speed, it's incredibly noisy. It sounds like a CD/DVD drive running at full speed. When I unplug one or the other, but leave them both attached, the noise goes away. That tells me that the fans themselves are not the problem, but rather how I have them arranged. They're installed in a Lian-Li PC-9F at the top rear as exhaust fans. From outside to inside, the configuration is:

Stock Fan Grill | Case with Stock Rubber Grommets | SFF21G | H60 Radiator | SFF21G

I've ruled out the obvious, such as the fans running against each other or at different speeds, so what could be causing the problem? How would you suggest that I solve it? I've considered installing a fan shroud, but would that be effective? If it's worth trying, where should it be placed?

Thanks in advance for any assistance you can offer.

You should definitely use a fan shroud. Try moving the fans away from each other until the noise goes away to determine what the length of the shroud should be.

here's someone with the same problem:

I just finished making and installing the shroud an hour or so ago, and you are correct that it fixed the problem. Thanks for your help, and for finding that thread. I did search, but I just couldn't find anything related.
