First build- strange cooling issues

post #1 of 3
Thread Starter 
Just built my first custom here are the specs;

Mobo- MSI 990xa-GD55
Cpu- AMD FX 8 core 8350 unlocked
Ram- 16GB 1866Hz Patriot Viper 3 (x2 8gb)
Gpu- Gigabyte HD 7970 OC 3GB (x3 fans)
Psu- 1000w OCZ Z series
X4 case fans (one exhaust, three intake)
CPU cooler- *Cooler Master V6 GT* push pull- situated to exhaust out the top vents
Case- Thermaltake MS-i cmdr snow

Now the reason I'm writing this is because I'm having an issue with the CPU fan. I notice when it's on, (even idle) that I get horrible vibrations being sent through the heatsinks. So I tried disconnecting one of the two, and they stop. Making sure it wasn't that particular fan, I switched the disconnected fan with the other one and it stopped again.
I get the following temps when playing crysis 3 very high settings and x4 msa;
Avg 25-30 fps
CPU -45 c
GPU- 58 c

That's with one fan disconnected.
Was wondering;

1) is this dangerous for the rig at these temps and one fan being disconnected?
2) how to stop the rattling?
3) should I invest in another cooler? Liquid?

I'm not OC yet, but maybe in the future, but not by much.

Any advise would be greatly welcome.

Are these bad temps??

temps look normal. you could have gotten a better cpu cooler for OCing tho. the vibration is abnormal. is it just 1 particular fan? or disconnecting either one of them stops the vibration?

could be a strange harmonic effect with both fans spinning but it's extremely rare to see that. just double check the cooler is secured onto your mobo correctly.

I made triple sure the fan was secured to the mobo-
And yes- disconnecting either fan stops the vibrations, leading me think its the rare harmonic frequency. I don't know of a better cooler for the price I paid for that one- I was thinking of going h90-100 or something but I don't like the idea/risk of ruining all my components from some bad manufacturing issue (like this one).
If I touch and hold the fan, my body absorbs the freq and stops. If I speed the fan up 100%, it stops- I was told sticky weights strategically placed could help- but I have no idea where "strategic" is for this massive fan.
