Help me make my PC silent

Hi all,

My main rig is great and I'm really happy with the performance of my Corsair AF120 and SP120 quiet edition fans.

The thing is though, it's quite loud. I can't tell if it's the fans or the airflow that's making the most noise so help me out.

I've got a Corsair 540 Air case with x3 AF120 front intakes at 7V.
Corsair H100 pushing out of the roof with x2 SP120 fans.
x1 AF140 exhausting out of the back.

I was considering going through the Noctua route, or removing my H100 and going for a good old fashioned air cooler. Space isn't an issue. The H100 looks tidier but it's just so noisy.

Or should I just replace my H100 fans for now? They seem to make the most noise.

Any help appreciated guys.

Alex.
 
Are the fans running at 100% all the time? If they are pwm, do you have them plugged into a 4-pin pwm header on the mb? You should be able to slow the fans down on the H100 to make them quieter.
 
Corsair link doesn't work with the H100 does it? You need an extra cable. I think my fans are running at 100%. They are not PWM. If they were could I control the speeds in the BIOS?

I'm a bit of a newbie when it comes to fan speeds. I have a Gigabyte Z77 D3H motherboard.
 
I went from a h80 > h80i to h100i and after yet another fail, went for the noctua nh-d15 - it's a beast and can only fit 1 fan on it but i don't regret it - very quiet and has been perfect.

PWM fans can be controlled in the bios, but also by programmes like speedfan. If the fans aren't 4-pin pwm then you might need to look into getting a fan controller...

Easiest way to make it 100% silent is to buy a 10m HDMI cable, some usb extenders and audio lead then put the PC in the loft or under the stairs and enjoy :)
 
Have a look at what fans you can control with speedfan. Then set custom curves for said fans and set speedfan to startup on logon and everything should be gravy.
 
They have to be running at 100%? as i am currently running 18 Cooler Master JetFlow 120mm fans in my water cooling setup, with PWM control i can get them as low as 750rpm and they are all silent?

Check your motherboard to see if it supports PWM and then have a play :D
 
Non-PWM fans may still be managable from the motherboard headers. You didn't mention what model of motherboard you have, but do have a look through the bios?

I run CPU, 2x intake, 1x front exhaust off the Asus Impact VII's headers, and it is almost inaudible at idle (Mechanical hardrive significantly louder than any other component).
Only the CPU fan is PWM!

Man, that sucks, only having one PWM header, I'm running the asus p8z77-v premium, every fan header on the board is PWM, so it's awesome for fan control.

I still think that the fans must be running at 100% to be the way he describes the noise...

It is not as bad as it sounds. I don't think the 200mm Bitfenix Pro is PWM at all.
The 2 120mm Parvums are, so it is a shame the headers aren't...

Even without PWM they go all do go down to inaudible (300-350 rpm) managed by BIOS based on CPU temps.



So I think @Wahzy needs to look in the BIOS to see if there is fan management there. If so, hook up everything to appropriate headers maybe using splitters.
