Which Noctua heatsink?

[ElectroShock]

So I am looking for an Air cooling solution that would keep my i7 4790k relatively cool, and I've narrowed down my search to those two models:

- NH-D15S + NF-P12 PWM (it would be running in two fan config, much like standard D15 or D14)

- NH-D14

 

The difference in price is marginal, and I already have the NF-P12 in my system (running with Macho HR-02)

Which one is better, when pure performance is considered?

NH-D15s. It is bigger and therefore, has more cooling surface area.

i believe the d15s is very similar to the d15 but comes with just one fan, if you stick two bad boys on it will be essentially a d15.

nh-d15 get it be happy

Both ship with two fans.

im so confused, i never wrote d14 and d15.

 

the d15s only comes with a single fan.

My bad. I though you made a typo. You are correct, the D15s does ship with only 1 fan.

ive got a better solution, get a cryorig r1 ultimate, in the uk its usually 10-15 pounds  cheaper than a d15 and performs the same if not a tad better, dno about eu prices.

NH-D15.

D15S! Performs as good or better than D14 even with the single stock fan, so with the additional P12, you'll get much better results. Also note that the D15 doesn't support PWM.

The fans come with D15, NF-A15, do support PWM.

my nh-d14 is amazing! a nh-d15 is slightly better so if the price is close I'd go with the d15.  I dont know if you can put 120mm on the d15 easily.  I know it comes with 140mm but have never used the d15.  Just looking at it it looks like it'd fit

I have a D15S cooling a 4790k - because I had the fans already I added an A15 and an F12 fan either side of the bundled A15 to make it into a triple fan cooled monster.

If you have the clearance adding a second A15 turns it into an NH-D15 with better compatibility - thus the reason I got mine: I simply could not use my previous model with both the top PCIe slot AND all 4 RAM slots populated. On an ATX motherboard setup this would be less of an issue to me, but having moved over to mATX with my last build this became a serious problem.

The D15 was already best in class, so since you have the spare fan already, get the D15s. (Essentially the only difference cooling-wise is the single fan it ships with).
