CPU Temps and Rattling Fans

[vp49p3]

Hi--P3dv4.1 on a 6700k oc'd to 4.6, W7, Nvidia Titan Pascal and 16gb DDR 3200 all on an  Asus Maximus Formula VIII board. The video card is also oc'd, with the original fan.  Whole rig is about a year old with a large Cooler Master HAF case.

The CPU is watercooled by a Corsair H105 horizontally top mounted.  About two months ago the Corsair fans became really noisy at high speed and then started rattling, even at idle. CPU Temps at idle are in the low 20's and at high load in P3d run 60-70 degrees, with one core going into the 80's occasionally.

I live in Florida and the room is rarely cooler than 80 degrees F. There are three other fans in a push-pull arrangement in the case ( front, rear and side). There is ample room for airflow around the case.

Do I have anything to worry about heatwise other than the noise from the rattletrap fans?

Sounds like it might be fan bearings. Fan bearings sometimes act up when mounted at the top of a case, rather than upright at the front. Something I always consider for top fans. Bearing type is a considerations. Surprised you would have that issue with Corsair fans.

Make sure nothing is loose on the fans of course, and make sure cables aren't getting in the way of the blades.

If it is fan bearings, what about RMA'ing them? They should be under warranty.

I had the exact same issue after about 3 months use with the Corsair H115i fans when top mounted.  Those fans are VERY high speed units. Personally, I'd swap the fans out for Noctua items.  Much better at doing the same job for much less noise;-)

Thanks much.  Will try your suggestions.

Any particular Noctua 120's?

I like the NF-F12 focused flow fans. Have several of them. Bearings are great in top mounted config, quiet, cool great. Work well on my daughters H100i V2. 

They do them in black now too if you don't like Noctua colours. :)

Thanks Martin and Dougal--will try those Noctua's.

Naaaa. That rattle is an "undocumented feature" that works really well. When the rattle stops, you'll know it has kicked the bucket and needs replacement. Other fan companies charge extra for early warning failure detection. It's like SMART for fans.

Not funny!
