toddnunez94 Posted July 24, 2014 Share Posted July 24, 2014 I've posted here a million times and I still can't figure this out. I have my H100i mounted in the top of my 750d, in a push pull setup using the SP120 HP PWM fans. No matter which way I install them (different screw methods) I still get this very annoying vibration. I've even added rubber mounts that came with the case. NOTHING... I can't tell if it's the top two fans vibrating off the radiator, or if it's the top fans vibrating on my case. however, when I press down on the top of the case, the noise slightly goes away, and sometimes it will be gone until I remove my finger. Upon startup of my computer, it will make an annoying vibration sound as if it's clinging to metal. PLEASE PLEASE PLEASE I HOPE SOMEONE HAS HAD THIS PROBLEM IN THE PAST, SO I CAN BE HELPED. IVE BEEN DEALING WITH THIS FOR TWO MONTHS, AND ITS MAKING ME PARANOID... This noise only happens around ~1300rpm and sometimes it will happen at different speeds, but always at 1300. I've had RMA'd my h100i twice (different reasons) and RMA'd my fans like 6 times (due to the strong force needed to install-- stripped out screw holes, and grinding sounds), so I know it's not the fans. My only belief would be the case. Link to comment Share on other sites More sharing options...
Faithh07 Posted July 25, 2014 Share Posted July 25, 2014 The SP120 fans aren't that great in absorbing noise. It only has rubber where the screws goes in thats it. Noctua's for example have it like this: http://ic.tweakimg.net/ext/i/1320939662.jpeg Thats just much better for absorbing vibrations imo. Link to comment Share on other sites More sharing options...
toddnunez94 Posted July 26, 2014 Author Share Posted July 26, 2014 Well I figured out what the problem is. I've been readingsomewhere else, and people claim that it has to deal with the fans being mounted horizontally. I've done quite a few RMA's on them, and no matter what, I still have the same issue. I love these fans and corsair, but I'm asking them for a refund on them. I really want to pick up some of the Noctua NF-F12's but they are twice the price. Almost $115 for 4.

iflo Posted July 28, 2014 Share Posted July 28, 2014 I have 2 Noctua NF-F12 and I was getting the annoying case vibration noise too. Pressing on the top of the case (a Haf-x) would solve the problem. I purchased rubber grommets to mount both the radiator and the fans but they made no difference. In the end I ended up ditching the screws and attaching the radiator to the case using wire cable ties. That completely cured the buzzing for me. Worth a shot as a cheap fix before you splash out on new fans. Link to comment Share on other sites More sharing options...
