Noctua NH-C14S, Premium CPU Cooler with NF-A14 PWM 140mm Fan (Brown)

It is pricey but doesnt compromise on anything. Super easy installation process and they even include a long screwdriver just in case you dont have one that is long enough. Plenty of clearance for ram and top pcie slot. Also the included fan is awesome: high performance with low noise.

Arguably one of the best air coolers out there for an SFF build. (5900x)

Cools my i7-4790K better than the stock cooler. After installing this cooler my CPU temperatures actually dropped several degrees which is great. I do not overclock my system but feel confident that if I needed to this cooler could handle it.

Big, beefy cooler for my OC needs. Definitely worth the price.

I am using this on a 2700X CPU and a Tomahawk B450 Board and right now it is running at 105 degrees F ... It is quiet but then again I am not a gamer but it seems to do the job ... even when my CPU is maxed out I have only seen the temp. in the 120 Degree area, wish I could say the same for my GPU ... but it is a older one, to be replaced soon... If you have a M/ATX case it wont fit, I can tell you from experience ... one way it gets interfered with by the Blue Ray Drive and the other way by the rear fan... it is a big unit ... I see people complain about the colors of the fan, if that is the case order a 140MM that you like but I really like a quietness and I have maxed it out.... You can mount the fan on the top or on the bottom and yes it clears the memory .... Hope this helps guide your decisions ... I am really beginning to think on these reviews that some people just like to downgrade everything ... I am happy with everything in my system

Absolutely Amazing Cooler. It Looks So Cool In My Case. Installed Easy. Did I Mention That It Looks Cool?

It fits like a glove when you need a low profile, premium air cooled heatsink. This fit just barely in my Corsair Air Carbide 240 MATX cube case and on a Gigabyte GA-Z170MX-Gaming 5 MATX mobo. I had to mount the fan on the bottom side to meet the clearance of the case, but if you have more space, you could add a second fan so that there are dual fans in push-pull config. I have it cooling an I5 6600K which is currently OCd and with Prime 95 running, Im still under 60C.

Mounting issue. When I lay the case flat down horizontally like a HTPC or rack server, the performance is almost as good as my Noctua D15s. Once I shift the case into normal vertical orientation, temperatures went from 63 to 72 degree Celsius real fast (Ive remounted and tested this multiple times). Ive also tested this with the heat pipes facing in every possible direction except for top-to-bottom, as instructed by Noctua. I guess this cooler is more suited towards HTPC chassis such as Fractal Node 304, because performance takes a hit if you use it in a tower case. My theory is that either the concave base loses optimal contact with the processor when positioned in a vertical orientation, or the bent heat pipes have trouble in that configuration, which might also explains the varying results from many different professional reviews on the Internet.

Average Temperature of CPU dropped ~10F with this cooler. Absolutely quiet as well.

I am giving the product 5 stars but not the customer experience. I received this, bought brand new, and gave as a gift. I was extremely embarrassed when the recipient opened the box and parts were free floating in the box. Two of the plastic bags parts were supposed to be in were ripped open. There was heat compound all over the metal plate. This was an obvious return no one bothered to check. While the part itself is great it took an additional 30 minutes to clean it and make sure all parts were in the box. Installation was fairly simple. I was impressed with that. My partial refund has yet to be credited to my account 24 hours later but that is an amazi problem, not a product problem.
