Quietest cpu cooler? - Page 2

post #11 of 71
Personally I'd still have one fan, you can get some fans that produce something like 10db, which is pretty much dead silent.

Especially because these 3570K's do get toasty under load. So passive cooling may be outta the question redface.gif

No vibrations on my Noctua either. AND I'm using 1 clip per fan, see sig rig. No room otherwise it'll short by touching GPU PCB

The issue isn't so much fan noise, but vibration on the case. The rig is on a glass top table which doesn't dampen vibrations but (just my theory) instead kind of reflects them back into the case.

I'll see how the cooler sounds at 900rpm i guess.

Maybe get a sheet of that sound deadening foam and cut it to the base size of the PC, stand the case on it
Meh

Look at my rig. It's 3 feet away from my desk. It's really quiet, I use speed fan and even at full blast at gaming they only run 1200rpm and Noctua's @ 1200rpm? They sound very quiet. Any less and they are utterly silent.

I came from a fractal r3 and the noctua fans comfort my need for silence. silentpcreview is good too as a resource if you don't know about it already

DeepCool Aeolus Big Frost

Which is also very big and weighs in at over 1kg, so perhaps could be used without the cpu fans installed. This rig has no discrete gfx card either so that equals less heat inside anyway.

My point was: one Noctua fan @500rpm will most likely be quieter than your case fans, therefore it makes sense to use one slow running fan on the Cooler. BUt obviously the best way to get to a defininite conclusion would be to just play around a little bit with and without a fan to see what the best suited config is for your specific situation.
The Deep Cool cooler will probably do the job too.

FYI my noctua fans aren't audible until they hit around 1100rpm...

between 500-1100 i don't hear anything increase in noise from 3 feet away, even with side panel off. i have them idle around 500rpm, any lower and speed fan loses control of them.

You need the neoprene gasket material between the fan and the cooler...

The way I solved it was to have all PWM fans and control them all with PWM signal from motherboard CPU fan socket. Set idle speed as slow as fans will run (a good cooler needs no fans at idle) and set fan yooer rpm to keep CPU stays below maximum temp. On mine that's 650rpm idle and if a cores are at 100% load fans spin 950-1000rpm with CPU 45-50c.... 20c below conservative safe 100% 24/7 use.

I doubt system runs loud enough to hear more than 2-3 hours a week.
