Cooling my Meshify C

neil_g · 20 Jan 2020 at 11:45

I don't know whether I'm overthinking this, any help would be appreciated..

Currently I have the Meshify C with everything running off motherboard fan headers:

Front Inlet - 2x 12cm Noctua NF-S12B FLX
Top Exhaust - 1x 14cm Noctua NF-P14 FLX
Rear Exhaust - 1x 12cm Noctua NF-S12B FLX
CPU Cooler - Corsair H80i + 2x NF-S12A FLX push/pull

"Hot" Components - i7-4770k, 980ti WindForce

Frankly it's all a little loud even at idle. The H80i isn't doing well at keeping temps down, even idling.

Was considering:
BE QUIET Dark Rock Pro 4 135 mm Silent Wings CPU cooler
Front Inlet - 2x be quiet! Silent Wings 3 140 mm PWM
Top Exhaust - 2x be quiet! Silent Wings 3 140 mm PWM
Rear Exhaust - 1x be quiet! Silent Wings 3 120 mm PWM

Don't know if this is
a) Overkill
b) Going to be any quieter on the motherboard headers and if so..
c) Are there any good budget fan controllers capable of 5x 4pin

So just 2x 14cm intake and not a single exhaust. interesting idea i'll take a look at that.

what fan profile are you using from your mobo? I think that all fans sound loud near to 100% of their max rpm, at 40-50% fans are usually reasonably quiet. For my ryzen 5 3600 I want the cpou temp to be <65ºC to allow the cpu to auto boost to its max - therefore I have changed the fan profile to being 50% from 20 to 60ºC and then to ramp the fans up to 100% from 60 to 65ºC (on my esports 34 duo air cooler). Most of the time the cpu temp is less than 60ºC and therefore is on 50% fan speed and fairly quiet. I suggest that you do the same/similar (perhaps you could even stay at 50% fan until 75ºC with your intel).

It's a Maximus VI Formula. Standard, Silent and Auto are all much the same. I've not tried the manual option yet.

Aren't those Noctua fans the low static pressure ones that shouldn't be used on coolers and filtered intakes? If so that could be your issue. I have the same case and it's silent at idle, it goes noisy under load but temps are good.

Noctua say P14 fine for coolers, cant see anything on the S12 one way or the other.

To said you had them as intakes, from what I remember they are no good for filtered intakes

yeah I cant see anything in the Noctua blurb that says that.

Both the redux and current version state low impedance applications, I just edited my post after a quick Google

right, I've found what you mean - https://noctua.at/en/which_fan_is_right_for_me

interesting they say they're okay for case cooling, but what case doesnt have filters these days.

to be honest, the H80i wasn't the best even with the old corsair fans. might just go back to air and try the 2x 14cm intake as mentioned above.
