We check out two different Noctua cooling units. One tower that leaves room for a GPU in the first slot and one beefy small form factor cooling unit.
Noctua has been on or near the top of the list when it comes to quality. Here we have some updates and iterations on other popular designs. The Noctua NH-D15S is basically an NH-D15 that has been shifted to make room for 1st slot graphics cards. The NH-C14S is an improved NH-C14.
Check out the video for all the details, overclocked benckmarks, etc.
Noctua makes excellent cooling solutions in general imho.
My only beef with them is the coloring/branding? that they insist on (same as Logan said on the vid). I get it, they want to stand out. If they gave more options as to color schemes that would simply make a lot of people happy. :)
Still though I insist. Great fans, low noise, feel solid and not too bad heat pipes as well.
Edit: My manners...geez...loved the video, as always nit-picky and to the point. keep it up, and thank you :)
I've got one of the low profile coolers in a HAF XB case. Push pull fans blowing downwards (the case is horizontal) and with ambient at 20-22 DegC I get 31 DegC idle, 42-44 DegC gaming and 50 DegC using Prime95 on an i5-3570K OC @ 4.2 GHz.
