I wonder how they would sell any other coolers than this one. According to HH's test, it's cooling practically just as good as the D15, yet it's more quiet... I like silent / quiet cooling very much, but I don't really see any sense in buying anything else than a D15S now, pretty much making their top products obsolete... this is somewhat odd I'd say.

Nice review HH thank you Best cooler I have owned DH15 dual fan silent and cool prefer it to my old H100i

Of course you're right fox, but if I test the same cooler on the same CPU, even average it out with multiple turns of TIM applying differently, it shows that the D15S is better than the D15... and it's 10€ cheaper here too. So if you can take a cheaper product, with pretty much the same performance, and a fan less to make it even more quiet, why should I take the D15 then? 🙂 Does the D15 allow turned installation, and the D15S maybe not? But why would you want the D15S turned if it is built for better compatability and spacing? Please help me figure this out 🙂

They need to stop releasing newer coolers it making me regret buy my D-14 before I bought the CPU and Mobo lol

You will get better cooling only using two fans on the outside of the cooler, blowing towards the middle of the cooler. This is how I have had my NH-D14 setup for a few years now. After extensive testing, the only way I have found to drop a couple more degrees with this style cooler is to set up a ductwork with a fan sucking the warm air from in between the towers... but that wasn't worth it because it took up to much additional space in my case.

so you would say having the 2 fan that came with the D-14 blowing air on to and out the back is best/?

Nice review but i never ever bother myself with these kind of cooling solutions again. I got a nice AIO water cooling. Much better and less hassle life since then 😀 This is my past regular cooler: http://www.thermalright.com/html/products/cpu_cooler/silverArrow_sb-e.html It was nice and cool but it is nowhere to my water cooler.http://www.coolermaster.com/cooling/cpu-liquid-cooler/nepton-240m/

I bought it with my new i7 6700K, i had NH-U12P SE on the i7 920 so i can't compare it with something relevant, but it's quiet and i can overclock stable to 4.9GHz with it.
