5 out of 5 eggsTop of the Line Quiet Heatsink

Pros: Not gigantic like the dual towers. Still big, but in another way.
Better than liquid cooling kits at similar or higher price range.
Quiet and cools well.
Great mounting system. Also simple and not a hassle. Instructions are fairly clear.
Does not block memory slots.
Good amount of accessories and includes a very good thermal paste that is better than most. Even includes a screwdriver!

Cons: Color Scheme (Some may mind, I didn't)
Blocks first PCI Slot - Had to move my sound card to a lower slot.

Other Thoughts: Packaging includes support for a second fan, but does not include the second fan itself.
With small FFT Prime95 running, I had 4770k at 4.2 GHz at 1.22v (Have yet to trim the voltage). It ran hot at 90+ C, but on normal loads like gaming, it runs well under 65C.

5 out of 5 eggsBig cooler with bigger cooling

Pros: Great cooling with low fan speeds

Cons: -Huge! Make sure you have room for this monster in your case.
-Fan color scheme is early eighties--brown doesn't fit my build style -much.

Other Thoughts: This fan has been installed and running for six months; has been ultra-quiet and provided consistently cool temperatures (below 40ºC) on my slightly overclocked i5-4670k (4.2 MHz).

5 out of 5 eggsAmazingly Cool and Quiet

Pros: It's quiet and keeps my AMD FX 8350 nice and cool.
I would even compare this to a closed loop water cooling solution.

Cons: It is big. But I knew that when I bought it.

Other Thoughts: Just barely fit inside an Antec 900-2 case without any modifications.
Corsair dominator Ram fits just fine if using the outside slots, but looks like the inside slots would fit too but would be very tight. However, the fan can be moved to the other side of the heat sink and then you'd have plenty of room for all your ram.
No issue with Video card clearance, plenty of room for me on a Sabertooth 990 motherboard.

5 out of 5 eggsIt keeps things cool

Pros: High quality heatsink with just about the very best 14 cm fan on the market. An outstanding cooler, outperforming most 'kit' water coolers. Easy to install, even though this thing is huge.

Cons: Size. Only could mount it 'horizontal', since otherwise I wouldn't be able to use the main PCI-16 slot of my motherboard. Not a major issue to me, since it's performance is hardly affected in my opinion

5 out of 5 eggsNoctua Quiet and Efficient

Pros: We chose the downward-firing version of this cooler for our vintage Core i7-965 Extreme Edition because the components surrounding the cpu socket benefit from having some air blow across them. The ol' 965 is a 130-watt heat monster, yet the Noctua maintains idle temps. of 32-36 deg. C. and peak temps. while gaming for a hour or more never exceed 64 deg. C. It manages this while running at only 900rpm (using the speed step-down option), and it's so quiet we use the system as a home theater PC. This result is achieved with 1 x 120mm front intake fan and 1 x 120mm rear exhaust fan, both running at a quiet 700rpm. The model on this page - NH-U14S - is about 2 deg. C. more effective due to the fact that it blows directly towards either the rear exhaust or top exhaust vent (instead of blowing downwards like our C14 version).

Cons: none except price!

Other Thoughts: n/a

2 out of 5 eggsDisappointed

Pros: Decent construction quality, excellent packaging, wonderful instructions. The actual mounting system for the heatsink itself was absolutely the easiest I have encountered yet. Which is odd considering the fan mounting system is absolutely the worse thing I have ever seen. If not the cheapest, it's like they're design department just threw their hands up, and when with the cheapest thing possible to mount the fan to the heatsink.

Cons: The problem is, that this cooler just will not work for me in a push/pull configuration without an annoying buzzing noise, loud enough to be heard across the room, inside a case with 6 other fans running at full blast. I have installed and reinstalled the provided fan and another noctua 140mm pressure optimized fan in push and pull and push/pull configurations, and no matter what I do, cannot get the buzzing to stop. With 1 fan in the cooler seems to work ok, but that leaves me with an extra noctua fan just laying around, since I have no room in the case for it :(

Other Thoughts: The fan mounting system for this cooler is absolutely terrible. I don't know what Noctua was thinking, using such a tiny little wire to mount these nice fans. That's the reason for the 2 star rating, from a company that manufacture's such high quality (although they're still hideous) fans, I expected a lot more than I got. They need to go back to the drawing board for the fan mounts (and the fan colors, but they've known that from the beginning and just dont care)

I can't really recommend this cooler, not with the buzzing sound it makes in push/pull, and not with such a half a**'ed fan mounting system.

5 out of 5 eggsFantastic !

Pros: not too big for an aftermarket cooler. easily clears my sniper ram on all 4 slots on my gigabyte z97 black mobo.
Every fin was perfectly aligned , not a single thing out of specs or even a single blemish. actually the packaging was better then some of the competitions actual product as far as the thought and detail that they put into things - total pro's . Every one know about Noctuas cooling abilities - I have two black Noctua 2000rpm industrial fans in push pull on a 14S and I will put that up against a H100 water cooler anyday.

Cons: not a fan of the color of the fan . replaced with 2 140 Noctua industrial black fans running at 1500 rpm

5 out of 5 eggsExtreme Awesomeness

Pros: This heatsink is out of this world amazing. Shipped in exceptional packaging and there was no damage to the product including the delicate radiator. It was also fairly easy to install with easy to understand instructions. This was my first time installing a tower heat sink and there were absolutely no issues (except one see cons).

My temps dropped 25C under load not going any higher then 56C. I'd recommend this or any other Noctua products to anyone; I'd even by a bedroom fan if they made one... do they make one?

If you are looking for a non-liquid heatsink, this is the one. I have only the stock cooler to compare it to but this thing rocks. Whisper quite and it looks like there is a motorcycle engine on my motherboard... no really it looks cool. Awesome.

Cons: This is a big unit so make sure it fits in your case. I measured prior to ordering it and I still couldn't believe the size when it arrived. For reference, imagine that you are mounting your face over your CPU.... maybe not quite that much but you get the point; it's big. I guess that the large size is one of the reasons why it works so well.

One small thing; the install was easy but there was a slight, minor issues getting the mounting screws to catch... probably because I was worried about pushing hard.

Other Thoughts: Buy this. You will not regret it.

4 out of 5 eggsGood Fan

Pros: Decent fan and comes with a lot of accessories, rubber bumpers, rubber mounts, extension cable, etc.

Cons: Not as quiet as the Noctua NF-A14 FLX. One of the 3 I bought had a rather unpleasant noise when given any voltage from my Zalman MFC. Swapped the troublemaker out for an extra NF-A14 FLX I had.
