Hi everyone,
I have a Noctua NH-U14s installed on a 4670k, right now it only has one fan installed on it. Basically i'm wondering if adding a second NF-a15 fan will help with performance/cooling under load, or if adding another fan won't change the temps. or anything like that.
Thanks in advance!
 
Solution
yes but only by 2-3'c, 5 at most.
if you do go a second fan then get a fan controller. as you can undervolt the fans to run them slower when the pc is idling which helps reduce case noise while watching movies.

Thanks, about the fan controller though, I have a define r4, will the built in fan controller be good for cpu fans, or is that only meant for case fans?
