Low RPM AIO for GTX 970

post #1 of 3
Thread Starter 
Hi,

I'm considering an AIO for my 970 to quieten it down. Temperatures don't generally go above 70°C - but fan speed is such that it's too noisy for me. If I were to pick up say a Kraken G10 and a 240mm AIO system - would this be sufficient to keep it cool (<70°C) with the rans running at a maximum speed of around 800rpm do you think?


PS - I'm aware the PWM will need cooling also, but want to see if it's a viable solution for me first.



Thanks

It's not the PWM that would need cooling, it's the VRM. You can solve that by using the Corsair HG10 N970 instead of the NZXT Kraken G10.

Yes, it is a viable solution, though if you get a 120/140mm rad you might need more than 800rpm. A 240/280mm rad would definitely be able to cool a 970 at 800rpm.

NZXT's AIO line has pumps that can be a bit more geared towards noise. Their fans perform well, but I wouldn't consider them particularly quiet. If noise is such a concern, you may want to replace the fan(s) that come with it.

I would recommend an EK-Vardar for pwm-control or Gentle Typhoon for voltage-control for the radiator in 120mm size.
I would recommend a Noctua NF-A14 PWM for pwm-control or Phanteks PH-F140SP for voltage-control for the radiator in 140mm size.

Thanlks for the reply - I did mean VRM not sure why I put PWM doh.gif

I've got room for a 240mm AIO in the bottom of the case, or a 140 at the front. 240 would seem to make more sense to me as it would allow a lower overall noise level (I would assume). Alternatively I could mount a 280 at the front set to exhaust and have 2 120's in the bottom for intake.


I'm assuming I can control the pump RPM via the fan header on the gfx card, and fan control I can look at via a motherboard header.
