Be Quiet Dark Rock TF with Noctua fans = silent, cool system?

[miha2]

Hi everyone. I'm thinking to "upgrade" my Corsair H80i, with the Be Quiet cooler. Why? Well, at times, it may be noisy in the summer, when it's really hot. But will it support 140mm fans? The official web site says it has 135mm fans, but... there is no such size on Newegg or Amazon. From well-known brands, even Be Quiet itself...

According to this web page: https://www.tweaktown.com/reviews/7444/quiet-dark-rock-tf-top-flow-cpu-cooler-review/index6.html the Be Quiet is pretty good. Maybe not as good as the Noctua NH-D15, but for my small case (Thermaltake Chaser A21) the Noctua is a little too big. But the Be Quiet "should" fit in; my gpu is wider.

Also, is it worth swapping the fans? The Noctua is (supposed to be, at least) quieter, faster (CFM is better), but... larger and so will not fit?

It's more out of the interest; it's not like I'm looking for what to waste money for, or anything like that; I just want to have a good, reliable, cool system, which will stay quiet at all times.

Corsair H80i

Noise level: 37.68 dBA
, I would bash my head against the wall if I had that in my system

Be Quiet Dark Rock TF

Noise level: 11.9 - 26.7 dbA
Noise levels are logarithmic. 26.7dB at highest RPM means it's at least it 10 times quieter than 37.6dB. 11.9dB at lowest RPM would mean more than 20 times.

I don't think changing fans would make much of a difference. You have to consider air pressure as well because high CFM is mostly used for the case fans, not the cooler fans.

Did you find Corsair's noise level on Newegg? The Tweaktown's review sounds more reasonably - when the cooler works at 100%, it makes a lot of noise; like someone speaking louder than usual.

Would installing the fans to the front help in that case? Or a larger case? I have a mid tower.

Corsair's own site.
57 on tweaktown. Forget bashing head, I would have done this instead.

Also, that's nearly equal to AC or Speech like you said.

They can help but not much. The biggest effect is the heatsink + more airflow inside the case. An exception is a soundproof case.

I also have a mid tower with 5 (3 intakes, 2 exhausts) running 100% molex + 1 heatsink. Never had any issues with noise while sleeping 6-7 feet away with the PC on. Heck, I can hear a fly spinning around me but I can barely hear the fans. (60CFM/19dB case fans, 22dB cooler).

Also, I use closed back headphones while gaming/watching. Definitely can't hear it with that.
