I have to agree and disagree at the same time. I have myself, same as you, speculated some time ago that the PSU might be contributing to the issue, based on the replacements presenting the same problem for many people, but the H100 I had was grinding on a Corsair HX 850W (powered off 230V) that produced a perfect 12,00 V (measured with volt meter). That's why I have previously speculated that perhaps a voltage noise (ripple) might be a factor in conjunction with the voltage. The extreme case was with a man from Poland also, who also had a Corsair PSU (AX 1200 I think) and he RMAed the H100 7 times, each time getting the same issue, and ended returning the unit for a refund.
Based on my statistics I do agree that the issue is more common among people with "12,3V PSUs" but it's not exclusive to that condition.

I can reassert that this isn't necessarily a voltage issue. My PSU is putting out a constant 12.288v. My H80 is making the aweful grinding noise... I built the voltage dropper, which dropped my H80 pump speed from about 2238rpm to around ~2000rpm. The grinding noise got *louder* after I used the voltage dropper. Maybe I didn't drop the voltage enough... I know some people have had success when the pump is around 1700-1800rpm (using a fan controller).

Either way, hopefully Corsair come out with a fix soon, and I can do my 5th (and final) RMA to resolve this problem!

Sorry to quote myself but I was thinking about this more this morning. I assume I would need to get the second cable on the H100 patched into the Molex power cable so that it essentially creates one cable with both power and the tachometer that I could then plug into one header on the fan controller? Would this require cutting and soldering or are there Y cables out there that can bring the two together? I wish I knew more about this stuff. I've been building computers for a long time, but have never taken the time to really dig into power, voltage, fan connections, and what all these wires are actually doing. I really should have a better idea of the power and voltage aspect of a PC.

To be honest, I'm still fairly surprised. I don't monitor our forums too closely or work in our customer support, but I do see our RMA rates, and they aren't anything out of the usual. I'm working with our in-house engineers and with CoolIT in Calgary to come up with a fix for this one - we're pretty sure you guys have the cause nailed down, so we'll verify it and fix it.
For those of you who've had multiple bad units, all I can say is that we'll do you right. I'll work out something once we have a fix in place. It's absolutely unacceptable to have multiple failures back to back, and it seems there's some lot code differences, so once we nail down the root cause and have a fix, I'll be sure to get you guys the info.
In the meantime, I appreciate your patience. I appreciate your troubleshooting skills, and I apologize again for the stress.
I've been at Corsair for 8 years, ever cooler, power supply, fan, and case has my input and personal seal of approval and it pisses me off when something like this happens.
Email me if you have questions: redbeard@corsair.com
I'll post back here when I have a fix - which will be provided free of charge to those of you who want it. I can't provide more details until I know more, but I'll have more info as soon as I can.

This is one of the best responses from Corsair on this issue, I really mean that CorsairGeorge, a lot of us have been really going through some issues with the new H series coolers. It wasn't that Corsair was not being responsive, but the attitude of the responses. WWLW was banned from Corsair's website when he started talking about the voltage dropper, which he made for free for instance. I am glad someone at Corsair is really looking into this, thanks for your response. I am on the 2nd RMA, and it is pretty quiet so far.

JayWill411 - It would have to be something like this:

http://www.angela.pl/galerie/a/aab-adapter-4pin-molex-3_14070.jpg

only with a female 4-pin Molex, not a male one.
Or maybe his controller can regulate one fan output while showing the RPM from another, then you could connect it easily.
I don't know what the guy on that video used, try asking him maybe.

After a conference call this morning we have a couple of paths to work on - it's not 100% a voltage issue. We've actually been able to eliminate the issue by dropping the pump RPM to ~1800 AND by upping the pump RPM to ~2700. Which means there are a couple of possible solutions.

I'm on this - it'll get fixed. Thanks for your patience guys.

Glad to hear it's being worked on.  I'm still convinced that it's more a mechanical issue:

 

1) Resonance

2) Critical speed

3) Bearings

4) Mis-alignment

 

Any of those could be "solved" by adjusting the speed, but that doesn't mean it won't crop up later after some wear and tear.

 

Looking forward to hearing about a solution though :D

This is great news! It does pose a question though. So I called Corsair customer service on Monday regarding my RMA, and the H100 is out of stock with an ETA for May 31st. The Rep recommended I call back on the 31st, to complete my advanced exchange on both my H100 and the bad stick of Vengeance RAM I have.

So my question is, should I hold off on the H100 RMA until we hear back from you on the status of a fix and how replacements will be handled? Common sense and my gut tells me yes, but I was hoping for some guidance to confirm.

This is indeed great and relieving news.
And I can't tell you how glad I am that there has finally been some official word on this.

I think that someone should drop an official word over at the official Corsair forum too - I can't, I'm banned from there for the adapters.

Ahh excellent thank you. In looking at that cable, I'd guess the tachometer side would need to be a male receptor, so the H100 cable can plug into it like it would on a motherboard header ... in addition to the 4pin molex being female. Basically a flip flop of the image you posted.

I'm pretty sure I get it now ... I needed to see a visual to piece it all together. Now it's time to dig around for a cable.

Thanks again wlw! Your support on the H100 has been invaluable.

Nice to see that they're taking this issue very seriously, I was just about to email them regarding the annoying noise.
