Summary: Exceptionally quiet and very efficient, I was running about 80C with the stock fan (on an Intel i7 4790) during gaming sessions. The stock fan was pretty noisy, too, so I switch to this Zalman. The result is impressive.
Summary: Buy this CPU cooler if you want to keep your processor cooler and eliminate the noise from the stock cooling setup. As a side-note the large copper fins look great and the product feels like it was built with great quality.
Pros: I made a mini ITX gaming rig from the EVGA Hadron Air and decided on this so I could push the air out the top fans (many smaller coolers simply push air up from the socket not angle it toward a case fan). This CPU cooler is keeping my i3-6100 @ 4.4 GHz under 55 C during gaming whilst being silent...
Summary: Always Trust a Zalman Never had a problem with any of there products and they always seem to cool almost as good as a liquid cooler my buddy had the almost seam setup i do and i am almost cooler than him or with in a few degrees
Summary: not as good as a water cpu cooling solution. but works great, at quite cool temperatures. without as much maintenance. it's large weighing a pound, so be careful when moving your computer after it's installed as any jarring can damage the motherboard. very happy with how it performs.
