Hi folks,

 

Just a quick question. Noise of standard corsair fans really annoying so looking to get some Noctua fans for the radiator  to replace the supplied one. Do I get 3 pin or 4 pin fans? I know it's a dumb question but using corsair link to run things...

 

It's payday tomorrow so will pull the trigger but what are the pros and cons of 3 v 4 pin fans???

 

Thanks in advance!

Are the current fans on the radiator 3 or 4 pin fans? Where do you have them plugged in? if you have them plugged into the motherboard or a fan controller that has 4 pin PWM then go for 4 pin fans. 4 pin > 3 pin since 4 pin has its own fourth channel for speed control. They tend to be a bit less quiet because of speed fluctuations or something.  I recommend getting a 4 pin unless you only have 3 pin connections on your motherboard, or you have a 3 pin fan controller you want to keep using.

step three - admit that she is right for the sake of your safety

step four - realize that you have accomplished nothing and she still thinks you were wrong and now she thinks you are even more stupid

Look at the current ones...

4pin fans support pwm which is one way to power a fan as opposed to dc which is used for 2 or 3pin fans. With dc, voltage is lowered to control rpm whereas pwm uses 12v pulses to control rpm. Since fans need a certain amount of voltage to start, pwm generally allows for a wider range of control. That being said, 4pin fans can also be controlled using dc. Which you should go for will depend on what type of control you have available whether it be a hardware fan controller or headers off of the motherboard and your own preference. 

Either is fine with the only thing to watch out for being that pwm fans tend to cost a bit more. If that isn't an issue, just go with the pwm version.

Fans using dc can be noisier than pwm or vice-versa depending on the fan model. Ticking noises occur in most pwm fans due to the pulse but can be mitigated by smoothing the signal and dc fans tend to have a higher min rpm.

Hi, whatever you do,  don't add CoolerMaster Jetflo fans to the H100, there are multiple reports on Corsair's forum about dead units after combining both. I'm on the same boat, Instead of changing the fans I had to adjust the curves/profile to reduce the noise, make sure you are on the latest firmware and if you end up getting new fans please report back on how they work with your rig, I'm really curious about it. good luck mate!

Ordered some noctua nf-f12 four pin fans......used them on a previous build but these are the industrial ones which look a bit better.....Will post when I get them in and check temps. Hope it's a good solution............these ones are driving me nuts!
