Corsair H100 / H80 / H60 noise, grinding pump - *fix* + official Corsair response - Page 3

post #21 of 1734
ok yeah i read on forum that by tapping on the hoses can help, i heard a couple of bubbles get passed though the pump. But still noise persists i'll give it a month see if it stops
thanks for your advice

I think that if it were air bubbles, slowing down the pump wouldn't work to begin with, at least I don't see a reasonable explanation to this. Sure, in some cases it may be air bubble, and in these cases slowing down the pump does not help, but in most cases it does.

I'd personally like to thank wlw for the voltage dropper. I really recommend this if anyone is having a pump-grinding sound from your Corsair coolers.

I experienced similar problems with everyone with my h80 pump making an HDD-like scratching sound. Corsair advised me to leave the case on its side and let the air bubbles be slowly removed from the pump. We'll i've been waiting for over a month now and nothing worked, so I decided to go with the voltage dropper fix. Here's a before and after video.

Delivery was extremely quick, shipped out last tuesday from Poland, arrived in California today (monday) Thanks a bunch! thumb.gif

Hey friend, that's beautiful!

The noise is super irritating because while it's not very loud, it can be heard over anything else and is quite disturbing.
I'm glad it worked for you so well. thumb.gif

And that's a nice PC too smile.gif


For some folks the effect isn't so dramatic, the noise is lessened but not completely gone.
I've analyzed the internals of the Hydro series units and I see a couple of points for improvement, in particular one that could fix this problem once and for all.
I'd need one of those units that I can't sacrifice for testing but that I can't do so theories will remain theories.
I don't know however why Corsair hasn't officially addressed this noise issue yet...

A small update.

I've been running with the dropper connected for 4 days now and it is still oh so wonderfully quiet! tongue.gif

Although I don't have a fancy video like ilikepie45290 does here is a before and after image of the temps of the CPU in idle mode.

The text is in swedish though. redface.gif

I have had my H100 for about 3 weeks now, no grind yet but I will stay posted. If it does happen, I will PM you on the fix.
post #30 of 1734
I own the H100 with the grinding noise
First I tried what's suggested on corsair forums which is laying the computer on its side for a while and gentle hits on the pump and tubes in case its because of air.
I noticed that the pump was quiet when the computer was down on its side but as soon as it was back to normal position the pump was back to the grinding noise.

I RMA'd the H100

Received the second one a few days ago, same grinding noise, and again no noise when computer on its side (I'm starting to think it was designed and tested only in that position before going retail rolleyes.gif )

Today I tried the diode fix, which dropped the RPM from 2163 to 1953 but it didn't go quiet like other peoples here. mad.gif

Just got a 2nd RMA approved (fortunately I don't pay shipping for RMA with NCIX).

I don't mind doing RMAs as I still have the cooling that came with the cpu and as long as I don't pay for shipping (thanks to NCIX) but it's a bit a pain in the a.. to get the radiator in and out of the case everytime.

I wish the next one will be better or that at least the diode fix will make it quiet, I like the look of the H100 in my case.

BTW Thanks to wlw wl for sharing its knowledge ! thumb.gif
