Yep I agree with daniSAUR. I have the 650D and my problem was fixed with a fan controller. If you don't want to go down the route of modding the case yourself a fan controller would be your best bet.
Yeah when air passing trough with high restrictions, the sound can be pretty loud. Recently got rid of my H70 because of the noise.
Yes I thought about buying a H100 but after seeing the review on yt I dicided against it![]()
Other reviews mentioned a realy loud pump as well. Now I want to get a nh-d14.
I think I will get some sort of those anti-fibration rubbers... thx for that tipps.
