Any "nays" in regards to the Noctua NF-F12? The case is a Define R4, Seasonic PSU. Want to stick with the silent motif.

Personally I would get the Scythe Gentle Typhoon, but Nocuta is still a great choice.  Here is a good read http://www.overclock.net/t/724577/the-well-dressed-megahalems-65-fans-and-112-setups-56k-warning.

GT was out of stock at Newegg, so I just ordered the Noctua. I really hope this solves the problem, and no other PC issues materialize. I may even need a beefier UPS soon...

I know you already ordered your fan(s), but yeah, that sounds like you just needed a replacement fan.

FWIW, I recently purchased two of the 140mm Cougar fans (highest end model without LEDs). They're practically silent in my R4 at 5V or 7vV. At 12V, you can only really hear them if no other electronic appliance is running at the same time in the nearby rooms.

Now, outside of a case, the 12V setting has a decent amount of volume to it, but surprisingly little given the amount of air it pushes. 5V and 7V are still great even outside of the case in terms of volume level and airflow.

That CoolerMaster 212 fan is dead. That early bearing failure means either it was a serious imbalance in the fan or a manufacturing defect in the bearing.

I can vouch for Noctua NF-S12 (case) and NF-P12 (cpu). Superb fans, very high performance for the inaudible noise they make. (even nice nonannoying wind if fully turned up)
NF-F12 is also pretty good, but not as quiet. You won't need that unless your radiator is very dense or very tall necessitating high pressures.
With low fin density heatsinks, like Noctua's NH-D14 or NH-C14, you can even use NF-S12 without any issues.

I'm using 3x S12 and 1x P12, none has failed or gone loud yet for 1.5 years, which is quite a feat considering I had major dust due to renovations.

I picked up the NF-12. Was a bitch to attach the clips used to mount on the CM's heatsink, and it's not completely quiet. BUT, no rattle.

Are you running it full speed? Noctuas generally aren't "silent" with 12V because they mostly run at speeds comparable to "medium" fans made by other silent fan manufacturers. Noctua (last I checked) doesn't make fans designed to run at very low, completely soundless speeds when fed with 12V. Fortunately they include resistors in the box to cut the power down to I believe either 9V and 7V or 7 and 5, I can't remember which. It's probably the former though as a lot of fans have trouble starting with just 5V. Use the "ULNA" lead between the fan and connector and the motherboard fan header and the fan should slow down enough to be pretty much completely inaudible.

It's not too bad, and it has been quite hot these few weeks. I have it connected to the PWM or whatevs. Never changed the stock fan settings in the bios.

Is it a PWM version or 3-pin version? If it's a PWM you can just tell bios to run the fan at like 50% until the processor hits 70C, that'll do it

To be honest, I tried once and didn't really figure out how. I actually worry that there's too little airflow in my case, my room is frequently hot.
