Corsair H100 / H80 / H60 noise, grinding pump - *fix* + official Corsair response - Page 25

Not all Corsair vendors are premium vendors IMO as reflected in the number of defective products shipped, recalled, etc.

I joined this forum specifically because I recently bought a H100 and was experiencing the grinding noise (batch 11499403). After reading this thread (prior to the post from CorsairGeorge) it sounded as if Corsair wanted nothing to do with it which 1) made me not want to RMA the unit [fearing receiving a unit with the same issue] and 2) dropped my estimation of Corsair across the board.

I PM'ed wlw wl and have to say, as many have previously, a massive thank you - I received the adapter today and it has eliminated the noise completely. Previously the rpm was ~2200, it is now stable at 1950 (steady 12.192v on a 750W modular PSU).

For the price, and my personal customer expectation of Corsair, I have to say I was desperately disappointed with this product. Thankfully, due to the kindness for a fellow tech enthusiast, my issue is now solved - but at an additional cost (no disrespect to wlw wl) that should never had been needed.

I am glad to see that a representative of Corsair is now actively involved in discussion for a solution and that this issue has now been 'officially' recognised on the Corsair forum. I hope that this will lead to changes in Corsairs internal processes to prevent such failures occurring again in future.

Appreciating CorsairGeorges' comments, having since read them, and appreciated the non-vertical integration and growth points I still have to say, in my opinion, it does not excuse a multi-national company such as Corsair from making such a fundamental mistake for a major product line.

All that being said the main thing I want to come from my first, and probable last post, is a huge thank you to wlw wl. 5 GHz here I come!

Thanks corsair George! Bought three H coolers, 2 x H80, and 1 H100.. only my last H80 has the "click"/grind.. It isn't "loud", but it is still audible even with fans going @ around 1000-1500rpm . I'll give it a shot with a diode in a few weeks if the noise is still there.

Hello all overclockers I recently bought this low reputation h100 cooler and I also got the same grinding noise from it. Well first thing I did, contacted wlw wl for one of these adapters. Didn't work for me though. Then I contacted the seller and they told me to bring the unit to them and get replacement. Did that and got replacement straight away but when I got home and tried if it had the same problem and there it was. Grinding louder than previous unit that I had altough it isn't grinding always as I'm tapping the pump the noise dissappears and when tapping again it instantly starts grinding. Seems to me that there's some part that is loose inside so when tapping the unit some of the parts inside gets out of it's place and starts grinding.... Now I'm asking them to get my money back and will never touch these closed system units again. Sorry for the furious text but im pretty unsatisfied right now about these coolers. Gonna try the good old air cooling for a while.

ps. sorry for bad english.

Honestly I think some sort of "fix" is already out. After returning my grinding one for another I got one that doesn't grind. But Instead it surges when I boot up my computer if I have the fans plugged into it. I seem to be the only one with this problem though so maybe mine is a different issue. But definitely after reading the representatives post I feel somewhat better and not ripped off. Maybe I'll give this company another chance..

I returned 2 H100s with the same noise. Either were purchased from Frys or Microcenter. Shame on Corsair, such an awesome product but the HDD noise is bull when I have only an SSD in my rig.

Okay quick update guys - we've tracked down the root cause, it's a tolerance issue in the ceramic bearing around the pump shaft. It affects only a small number of units, but we've immediately tightened the screening process for these components so we can assure this won't happen any longer in production.

Once we have the new production units in-house, I'll post a method for those of you who want them to RMA your unit for them.

Keeping you updated as promised - I'll post more when we have the units in-house.

I can tell you the overall return rate on H100 is very, very low single digits. Like, below a mortgage rate. I realize that doesn't help those of you with the problem, but if you haven't purchased one yet, keep in mind that for every person with an H100 problem there's almost 100 people without a problem.
