Corsair H100 / H80 / H60 noise, grinding pump - *fix* + official Corsair response - Page 37

post #361 of 1734
This is seriously ridiculous.... I have gone through 3, yes 3, not 1, not 2, but 3 H80, still, all 3 of them have the same pump noise issue... to think that I am losing my mind over a cpu cooler!
I don't know Corsair, I really don't, it's been a while since I have been through such a terrible experience. My only hope now is wlw wl's solution, guess I will just have to wait and see...

To say that I am disappointed from such a magnificent company would be an understatement. It's a shame.

I recently installed the corsair h100 for my fx-8120 in my nzxt phantom black case,performance wise im very happy with it,temps are incredibly low.But...as many of you i also suffer from the rattling noise coming from the pump.But when i lay the case on its side,its completely silent,but this isn't really an option for using it 24/7. When i boot up my machine when i have the case standing up,the noiseof the pump is very audible,but the sound get less and less when i use my pc for a while.

I own the Corsair H80 cooler, and while I don't currently suffer from the "really bad noise" issue I have a slight issue with the noise the pump makes as "normal".

Note I did experience the "really bad noise" when I first got the cooler - I tried it outside of the case just running off a MOLEX connector and when horizontal I got awful noise - a really loud screech noise, rotating to vertical cured this as did tapping and generally moving about the hoses.

Anyway, while I think that is a significant issue with the system it's not the reason for this post.

The pump I believe is working correctly for me, but I can still clearly hear the pump operating over all the other noises my computer makes.

The rest is by no means silent, I'm running the standard Corsair H80 two fan setup and my case also has another 120mm fan mounted at the front. The PSU also has a large fan. The graphics card has two fans on it. So in total I have 6 spinning fans in my case.

Even with that I can clearly her the drone noise of the pump in the system, it is a very clear sound, much higher pitched than the fan noise.

From monitoring I can see the pump is running at 2083 RPM.

As a test I made a cable to run a molex off an adjustable fan controller and got the following results.
Voltage was measured using a multimeter, RPM was from ASUS AI Suite II monitoring.

Voltage RPM
9.5v 1376
10.0v 1513
10.5v 1634
11.0v 1781
11.42v 1890 (Maximum voltage fan controller could output)
12.18v 2083 (Connected directly to PSU Molex)

At 9.5v (1376) the pump was essentially silent even with my head in the case.
At 10v (1513) the pump was noticeable over the rest of the case components, but when the case side was on it was not detectable
at 10.5v (1634) you could just about here the noise
at 11v (1781) the pump was clearly audible when sitting normally, but not a nuisance noise - i.e. if you listened for it you could hear it.
at 11.42v (1890) the pump was a nuisance noise - the drone was annoying
at 12.18v (2083) the pump was not much louder (perception) than at 11.42 - it was still annoying and by far the loudest perceived component in the case.

My computer was build to be quiet, but not silent - I've got standard fans as provided by the case, PSU and graphics card manufacturers, yet the pump is clearly the loudest component of all.

I guess I'm asking is this normal - reviews seem to describe the pump as silent with the fans being the loudest part of the H80, but on low setting and idle the fans for me are pretty silent.

Thanks in advance!

@Marcus

From what you described, I believe the pump noise you are experiencing is not normal or intended. From personal experience with my H100 pump, it makes an audible noise that is louder than all 7 fans in my PC combined at anything over 1800RPM. At 1770RPM the pump is dead silent, and my CPU temperatures have remained roughly the same. Interestingly, my pump noise starts to diminish as it approaches max RPM, which lines up with what Corsair George said about their testing and being able to eliminate the noise below, and above, a certain RPM threshold. I believe that if I had a way to push my pumps RPMs past 100%, the noise would also drop to silent.

I believe your pump is falling within this resonance threshold, although you're having to drop the voltage more than I am to eliminate the noise. Mine goes silent at about 10.9v, or 1770 RPM. This may be due to differences in the H100 vs H80 pumps (if any).

The only thing making noise in my cabinet now is the water pump on my new H-60. I thought at first it was the old video card with a huge air cooler that was the problem, but the noise still persisted after I switched it for a new Asus gtx 670.

It's a grinding noise like many here have reported and I'm keen to know the outcome of this. I will return my unit to the shop I bought it and hope to get one without the noise problems.

My H100 makes a noticable noise. I have 3 H5O and none of them make any noise at all.

Has anyone tried laying the case side to side while it's running to rule out air bubbles stuck in the pump?

so i guess its normal for a h100 to stop working after a week?

I suggest that people that still have the rattling problem after RMA and lowering voltage to 12.0 volt should replace their PSU

That is sad.

As I already wrote a few days ago, can you just let us know where and how did you find your data to build this small-talks statistic? if you can't disclose it, that's just a bad marketing trick.
I've just RMAed my sixth H60, don't know which is the worst of them but my flatmates have been really laughing like mads for a month, and I guess they won't ever ever ever buy a corsair product. BTW, because of this, I bought samsung memory instead of corsair, which in the old rig just gave me problems.
