Corsair H100 / H80 / H60 noise, grinding pump - *fix* + official Corsair response - Page 20

post #191 of 1647
I got my fan controller today (NZXT Mix). Unfortunately I did not have a molex to 3 pin female adapter. I thought I did but I may have used it on someone else's computer.
Anyway, a couple of questions...

Is this adapter going to do the job?
Where should I plug the fans in? Right now they are both plugged into the motherboard on a Y adapter (COUGAR CF-V12HPB)
Will running the pump on the fan controller create any issues with monitoring it?

And on a side note - I had to replace my PSU because my wife's was acting up. So she's got my Corsair 600w and I picked up an OCZ-ZX 850w.
I had 12.192 on the +12 with the Corsair, the OCZ is 12.096. The RPMs do still seem to be high (2246)
Best part is, the pump now seems to be silent. The loudest thing I can hear is a cheapy 120mm fan that's getting replaced in a few days.
The humming pulsating noise is gone.

Should I still go for using the controller to lower the RPMs of the H100? I'm leaning toward yes because the voltage is still a bit over and the RPMs are a bit high.

EDIT - I found a cheaper adapter on Amazon. Looks like exactly what is needed

Both adapter are suitable.
If the pump is silent, leave it as it is, but get the adapter just in case. If it starts the noise again, you'll have a cure ready.

The lowered voltage will not interfere with the pump's RPM reading on the 3-pin connector coming from it.
You can have the fans connected where you like, including the H100 - but if you use a fan controller to slow it down, make sure that the fan controller has enough power output on that channel.

I just installed a new one and it's been running fine about 10hrs with no rattle. I think I'm going to take your advice and get a remedy ready just I case the noise starts. So much for this being a low cost, simple,alternative liquid cooling solution lol. If it wasn't for you I' wouldve lost my mind by now. Thanks for all the info in your threads.

I got my H100 installed in a new build this weekend, and while I wouldn't describe the noise as grinding or rattling like a HD read/write, the pump has a high pitched whine that is annoying and quite audible even with the case closed. In addition, the fan controller appears to be borked as I can't get the fans to change speed on any profile. So since I also ended up with one bad stick of Vengeance RAM that I needed to RMA, I called up customer service to discuss that RMA as well as an advanced exchange replacement for the H100.

When she checked stock, the Rep found that they had no stock on the H100, with an ETA not until May 30th. She was surprised and said after entering many RMAs on the H100, it was the first time she had seen it out of stock and with an ETA so far out. I'm not trying to look into this too deeply, but I wonder if they have a new build lot coming that has at least tried to address the issue.

With that said, is there anything on my current unit I should take note of besides the Lot # and maybe the pump RPM that the BIOS is reporting for comparison purposes?

A picture of the PCBs, for comparison purposes with the one you might get from the supposedly new lot wink.gif

Or don't, I have those, but take the pictures of the replacement biggrin.gif

I had a H60 for 4 months, cooling an AMD Bulldozer, although in dual fan set up with open case at al times cooling performance is not that spectacular with pump @ 100% = 4300 RPM and corsair and zigmatek push-pull fans @ 1200 (fan noise threshold) = 40 degrees Celsius.

Pump makes huge high pitched whine noise at 100% (4300 RPM) and is the most noisy hardware in my case, I was able to control it's speed by changing Asus Cross Hair Formula V motherboard CPU controller to DC instead of PWM, almost silent at 2500 RPM, sometimes decently humming @ 85% (3800RPM) but tricky to get to, dropping from 100% to 85% (asus software or better speedfan) will not do it most of the times you have to go from lower speed (2500 RPM) to the 85% !!

What I am trying to say is that for the H60 at least, for a given pump rotational speed (displayed at least by software as the same speed) the noise level could be radically different, so take your time playing with the pump speed "transition" from lower or higher speeds to the desired one until you get lucky like me(happens frequently ! ) and land on a sweet spot.

other thoughts: I am thinking tightness of the H60 to the mobo and how level and balanced it is attached might influence noise level.

Keep in mind that the actual speed of the H60 is half of what you're reading, so it's 1900RPM not 3800RPM, and that's the speed at which most H60/80/100 stop the strange noises that they do.

Also I agree, the mechanical stress from the way it's mounted, i.e. the screws not being uniformly tightened, might contribute to the problem.

Thanks for the info about RPM, just to add that in my experience the RATTLING noise happens sometimes between 95 and 75% depending on how you get to that point of RPMs but disappears after you do couple speed " transitions"; in my experience same RPM could be quiet or noisy that happening in a semi random manner!, but the 100% speed has definitely a constant high pitched noise to it.

I have been having the hard drive noise grinding problem with my H60 for a while now. I decided to try to plug the pump to my case's built in fan controller. The 650D fan controller is a 3-switch one and I leave it on the highest setting all the time anyways and my pump is now much quieter. Currently monitoring my temps to see if they change.

Just built a new rig this weekend with no knowledge on the H100 issue. Got the H100 from Amazon; batch 12129043. Grinding noise is there and it is extremely annoying. Louder than anything else in my case. Sound is much less noticeable when the case is on its side, but this is not a compromise I am willing to accept.

Going to give wlw wl's fix a whirl and report back!
