Corsair H100i - noisy

[skaftisveins]

Hi guys,

 

I've seen people talking about how they can't hear their Corsair H100i unless they put their head inside the case or something like that. My H100i is definitely audible from about 1m away when it's closed inside a Corsair Obsidian 450D case. Does this mean I have a defective pump? I don't think it's the fans although the ones im using are Corsair (2x SP120 QE PWM-4pin) which are both running in quiet mode in Corsair link (1000 rpm) and the noise is still audible. In HWMonitor the pump is said to be running at 2300 rpm.

 

Fans in case

Two Corsair AF120 Quiet Edition (one in the back and one is sitting at the bottom) - Both running around 1000 rpm

Two Original Corsair (in front) - Both running around 650 rpm

 

PSU is Corsair AX860

GPU Gigabyte 760GTX

Cooler H100i

 

It's a gentle whirring sound, but high-pitched enough for me to find it annoying. I tried capturing the noise with my phone, let me know what you guys think about it.. https://www.youtube.com/watch?v=mBx-ue8GarI

 

Thanks!

Video is private  put it to 'unlisted'

Can you stick your head inside the case and tell me where the sound is coming from?

Unplug both your H100i fans and see if you still hear the noise.

 

Also, how new is the H100i?

well, the h100i is a pretty loud cooler anyway, try  unplugging the pump while its on and seeing if the noise goes, then that will determine if its the pump for fans making the noise.

I have an H100i and I can't hear it unless my fans are on max speed.

The video should be set as unlisted now, please try again

 

The sound is coming from the radiator area or the fans which are mounted on it pushing the hot air out of the case.

 

I got the  H100i in July, so brand new.

 

I'm not so sure about unplugging my pump when the computer is turned on =/

 

also not comfortable to unplug both fans in same situation.

Yeah for me it sounds like the fans. I guess to get less noise you have to run them under 1000rpm. BTW; even with my NF-F12s (not a full speed ofc) I can hear fan noise because the densely packed finns of the rad create quite some turbulance.

A noisy pump usually rattles, and in your video I did not hear that noise my faulty unit produced, so it should be ok.

Here's the funny part. When I play with speed on those monsters in corsair link i can get them as low as 350 rpm. Still the noise is there and does not change at all. Is the H100i pump really that loud???  <_<

How did you mount the rad? Maybe the case vibrates and amplyfies the noise? In this case some rubber washers could help... In my case I really can't hear the pump outside the system.

[skaftisveins]

it's mounted in the top of the case with push set-up. The radiator is fastened with 6 screws at top which all have rubber-washers. The fans sitting upside-down on the radiator are fastened with 8 screws. What else could I do to ensure the setup is not vibrating.

 

if you want to see the same setup running at 350 rpm's then go ahead

 

This is so strange

I'm 90% sure it's the fans. The stock PWM fans that come with the H100i didn't work for me either. They made a grinding noise, but when I turned them up to their max speed the noise would go away but the fans were extremely loud.

I would try replacing your fans, and that will probably solve the problem.

[skaftisveins]

well here's the thing, i'm not using stock PWM fans

 

I bought sp120 3pin. although what I got in my case is sp120 4pin PWM (the store obviously gave me the wrong box, sine my receipt say SP120 3pin.

 

same as here

You think this PWM version of SP120 could be acting like the one that come with H100i ?

[Spannerhands]

Just unplug the fans, turn the system on, listen, and then you will know! Simples!

[skaftisveins]

If i stop both fans nothing changes.When i unplug the pump the noise goe away. Faulty pump with annoying whirr whirr noise.
