Which one's more quiet?

post #1 of 7
Thread Starter 
I am building a new rig and I am stuck between the H70 and NH D14.

Since my goal is to keep the machine on 24/7 in my room, where I sleep (my room is rather small too) I am trying to find the quietest solution possible but at the same time being able to adequately cool a OC'd 2600k at 4.4GHz.

So between the two coolers which one is quieter?

I also heard you can mount a 3rd fan on the D14? Is it worth having that extra fan (assuming my case will have enough clearance for it)?

Go D14. H70 is decent, but can get load. I have a Corsair A70 and im super happy. But D14 is best u can get, without getting an actually water block.

D14 uses quieter fans than the H70. The only significant advantage of the H70 is use in a space constrained case. D14 will cool significantly better than the H70 with the same airflow amount.

The third fan on the D14 can make a 1-2 C difference but it depends upon the fans. This is ehume's testing:

Didn’t sound as loud as its SPL.

Putting a third Noctua fan on does not make a difference at all. It is probably better to reduce noise and save money by sticking with 2 fans.

Yeah, I have two systems running the H70. No doubt it's a good cooler and looks good too but the stock fans are terrible. I replace them with Gentle Typhoons.
