Quiet high performance fans? - Page 2

post #11 of 56
Heh, hit submit instead of preview, and no edit function.

Your Delta 3200RPM fans are the source of the noise. I must ask... why did you start out with such high RPM fans... and why are you doing a knee-jerk reaction by going from super noisy to "silent?".

BTW, moving parts = not silent.

Why not use a fan controller (or motherboard controls) to reduce RPMs with your current fans? Reducing to under 2000RPM should decrease noise significantly over 3200RPM, while not impacting temperatures that much. Reducing to under 1200RPM would be downright quiet for most people accustomed to noisy computers, though temperatures would start to rise. You can balance noise with temps to find your own comfort zone.

More fans = more CFM without significantly affecting noise.

7 140mm fans at 700rpm? Tons of airflow.

I run 4 140mm fans in my fractal design R4 case. I have one thermalright x-silent, and 3 fractal design silentseries R2 (I got these 3 free).

I wouldn't put too much thought in the reviews of fans by other people.

I did a write up on that here.

The short of it is, the build quality on fans in general varies significicantly, and also changes in the shipping of the fans. Cougar fans might be great for someone else, but then you order a set, and every single one of them hums at 800rpm. (my experience). Even the slightest drop during shipping, either to you, or to the store you bought them from, can crush the bearings.



Some people might consider this blasphemous, but I turn my overclock off in the summer, and undervolt.

Drop to stock clocks for cpu ang gpu, disable turbo on my i5. I can undervolt a good 0.125 volts offset, across the entire spectrum.

Beyond that, I use EVGA percision X ideal settings to make my GPU have limited clocks. I also permanently undervolted the GPU (year round) at idle. It gives you only the clocks you need for a set FPS. Turning on adaptive Vsync is pretty useful too.

Back before I had a geforce 660, when I had a 260, I permanently, year round had the idle clock on the GPU underclocked 50%.

i have two NoiseBlocker BalckSilentPRO PL-2 in my build
120X120X25mm
1400RPM
56,5 CFM
11 dB/A

i love it how well they perform and how quiet they are smile.gif

High performance = good air flow or pressure. I would recommend Noise Blocker B12-PWN. I personally own these and think they are the best fans, personally.

Yes also Nosiblocker Multiframe or SP120@7V, not really silent btw good fan Noctua NF-F12

Yeah, I know they're the source of noise. I was about to go WC before and then I opted out so I'm stuck with them I guess.... Well, I just decided I love it dead silent, it feels better and I can actually hear crap rather than playing games with fans blasting in the background. I think 1600-2100 RPM is suitable for me, but I don't want fans that are horrid at dissipating heat nor do I want to spend a fortune on Corsair/Noctua fans...

Those fans are pretty expensive for the performance they have.... I'm not sure if it's worth the investment.

Are the Corsair AF any good? Thinking of getting some for myself ^_^

Very nice. I might consider these. already using the Fractal Design Silent Series R2 FD-FAN-SSR2-120 which are very similar. but 15 dB/A but only 40.6CFM but they seem to do the job.. I'm not sure that i would even notice 4dB/A per fan. maybe i would? but thats a decent ammount of more airflow. however im not too big on the fan color of the noise blockers

I believe the Cougar Vortex does a better job for the price and it appears to be a bit quieter too.

It's 60 CFM + 17.7 db
