New Case Fans, Please Help?

post #1 of 9
Thread Starter 
Hi everyone, so I just built my first rig last week and while I love the performance, the rear exhaust fan that came with my Corsair 300r is pretty loud. So basically I want to replace that fan and buy 3 140mm fans, two to mount on the side to cool the gpu, and one as a top exhaust. I will be using a fan controller (NZXT Sentry Mesh). So I need 1 120mm and 3 140mm fans that move a decent amount of air, but will be dead silent when turned down on the controller as I will be sleeping in the room with my computer on. Oh and sub $15 would be great. Any suggestions are welcome. Thanks.

HI,

I've faced the same question in the past month. Finally, I decided on the Noiseblocked PL-2s which are 120mm and until now I really like them. On 50% they are dead silent and moove a decent amount of air. When you are gaming you can turn them on 100% when you start to hear them but the amount of air pushed is bigger. For 140mm My brother has Corsair Sp fans that are again great and even make your interior of the case look better (if you think that's important).

The NZXT fan controller has 5 channels so you could keep the rear exhaust and just downvolt it. For a good review on the noise level and profile of fans at different speeds, definitely check out silentpcreview, as they have 2 140mm fan roundups and 2 120mm fanrounds. The last 140mm roundup has results from all four roundups on the last page. That should point you in the right direction in terms of the fans you're looking for, how loud they are, what kind of sounds they make, and how they perform at different rpms.

I am also guessing you mean $15 per fan? Or sub $15 for all 4 fans you're buying?

Thanks, I'll check them out.

Thanks. Also nice idea about using the fan controller for the rear fan, that would save me money. I will check out silentpcreview, thanks for the tip. Also It's 15 per fan but that can stretch to 20 now that I have to buy 1 less fan smile.gif.

You could use all PWM fans and a PWM splitter with molex power and control them all with PWM signal from CPU fan socket. This way the fans ramp up same as CPU cooler does when CPU temp increase. I've been doing this for years and am seeing more doing this all the time. wink.gif

I considered that but the two side fans will be for graphics card cooling not cpu so manual fan control makes more sense. Also, I don't really like the pwm control on my motherboard.

Assume your graphics card has PWM fans (most do now) you can use it's PWM signal to run fans too.

Hmm interesting. How exactly would I do that?
