I keep the profile on balanced and the noise has been a non-issue as my case is under the desk

The stock water cooler was making an awful noise every time the temps went up.

Holy crap, this thing makes more noise than my factory fan

just for the scary noises is not perfect.

Makes a horrible grinding/rattling noise

No more loud fan noise for me.

(continued) after a couple of months i just tried again and noticed that i was missing a piece that i did not know where to put now with that piece i was able to assemble it and now it works perfectly (the instructions where not very clear to be fair) its awesome, no noise at all and it actually looks cool.

I bought it January 2015, a month ago it started making a terrible noise

Note: the first time I booted with this cooler installed, I heard a bunch of loud gurgling noises and thought for sure it was raining liquid all over my PC

About noise the H55 it is very quiet in order to give the best performance/low noise radio, about the H80i GT the SP120L fans are so much louder but you must consider 70 CFM of flow and 4,65 mmH20 of pressure, and that means power and you see clearly the results (check GPU-z screenshots), about pump noise I read some reviews here warning about pump noise, in my case with the H55 pump (1500RPM constant speed) and H80i GT (1850 RPM quiet 3000 RPM performance), so far I have not heard any noise, very quiet both pumps

But since some months from now, If I let the PC turned on for 6 hours or more, this thing starts to do some weird noises, like if a cable were touching a fan (?), and if I turn off the PC and turn it on again the sound goes away inmediatly

It makes little noise, and works great

: Well, the darn thing sounds like something has broken within the pump as there is a terrible grinding noise that gets louder as the temp goes up

This new H55 model does not seem to be made as robustly as the old, and the low noise silent fan that came with this unit is anything but.

just for the scary noises is not perfect.

However after a few months of use it started making this horrible rattling / clicking noise

Liquid cooler itself is fine and does its job well but the fan that came with it started to make noise after 3 weeks and ruined the whole "quiet" experience.

It also is not a pleasant 'whoosh' noise

The stock water cooler was making an awful noise every time the temps went up.

The noise was so annoying that I decided to replace it

Both started out fine, but now make a super-annoying rattling noise.

It make some odd ''gurgling'' noise every so often, but no leak thus far.

So if noise is a concern better to have a quieter fan available just in case

This Corsair brand fan is much quieter then the one I

Now when I encode videos, the hottest I've seen my CPU get up to is
