Which cpu fan replacement should I get?

Last response: in Overclocking

I need a fan to replace my hyper 212 evo fan. I need something that is really quiet. This is how the cooler looks like.

These are the fans I found to be really quiet.

If you have better fan suggestions tell me. But those 2 above are really great options. Don't worry about the money. I just need something quiet to not bother me. Also, my i5 2500k is overclocked to 4.0 GHz if that matters. My pc case is the CM HAF 922.

~Thanks.

Also if it is possible, is there a quiet VGA cooler that I can use to replace on my EVGA 560 Ti? The 560 Ti doesn't allow me to get its fan speed lower than 30%.

of those 2 fans, the cougar has a higher CFM and a lower DB lvl, so that's probably the better choice

edit: ct1615 has a better answer :p

completely meaningless. CFM and DB are placed on a package by the sales/marketing dept. not an independent test facility. i can place 100 CFM and 15DB on a fan package that hardly turns and makes noise like garbage truck. Noctua, antec, and scythe are more accurate then some other companies (cooler master). i have a scythe on my cooler master 212+ evo, works fine and is silent.

Woah that's interesting. I was just about to buy the cougar 120mm. The scythe goes up to 26.5 dBA, but the Noctua is lower than that. Should I just go with the Noctua?

something to consider is that the scythe fan above has more CFM than the Noctua at 54. Do you think 54 will be enough on an overclocked i5 2500k OCed to 4.0 GHz? I am using this fan to replace the hyper 212 EVO cooler's fan. I plan on putting this cpu on a considerable amount of pressure.

my scythe fan cools just as well as the evo fan. gaming, my 2500k does not break 50c. it is at stock settings but then again the fan rarely spins at top RPM.

the real issue is; a fan can only do so much and the evo is a budget cooler ( a very good one). if you really want to push your CPU in OC, perhaps you should look at a heavier cooler.

Do you think a fan with 54 CFM is good enough to replace my evo's fan? I want my 2500k to be at 4.0 Ghz overclocked, the evo does just the job for that, so I don't need to change my cooler.

the noctua will do the job. maybe your CPU runs 2-3c hotter with it but the noise will decrease and it's not like you lose FPS with your CPU going from 52c at load to 55c.

P.S. my EVGA 560 Ti only gets noticeable at 40% RPM. why do you want to drop it below 30%?

Oh the noctua nf-f12 is a pwm fan. I think this is a great selection then. it is 120mm right? I want to get lower than 40% rpm so that I can sleep with the 560 Ti on.

Get the Noctua NF-F12. Quiet, high Static Pressure, long life bearing, 6 year warranty. I've got 7 Noctuas in my rig, couldn't be happier.

Not sure about the 560Ti. Might be able to edit the GPU BIOS to allow lower fan speed.
Or get something like this,

Choose very carefully, you never know whether it's gonna fit.


MSI Afterburner lets you adjust it too, and its less dangerous

I use MSI afterburner, and EVGA told me the fans don't go past 30% speed, and this is with a graphics card firmware update.
