5 out of 5 eggsQuiet & Cool

Pros: Quiet, efficient, inexpensive

Cons: It's slightly smaller than a Buick

Other Thoughts: I installed this on a Core-i7 5820k 140w (not OC'd), and ran OCCT for 1 hour, no core exceeded 76c, and the average was about 70c, all this in a fairly cramped mid-tower case, even under load it was very quiet. I don't think I would overclock with this, but for us non-OC'ers It's quite adequate

3 out of 5 eggsAlmost perfect with 1150 CPU socket

Pros: I didn't buy it myself, but I'm installing it on a MSI H97 mobo (mother board) for a friend

1- Installation is a breeze, in less then 10 minutes : the time it took to look up the included manual, apply the included MX-4 thermal paste and drive in the included 8 screws. IMHO, Their manual is "the standard" by which all other CPU heat sink manufacturers should go.

2- Comes with a very good quality thermal paste - Arctic MX-4 -, enough for much more than one usage (if you have to remove the heat-sink or modify its orientation, whatever the reason, you'll have more than enough paste to install this 3-4 times).

Cons: 1- (-2 egg) When oriented towards the back-chassis outtake fan (in a push config towards the rear), as it should be by most air-flow chassis "standards", the fan overlaps over the first memory slot (DIMM1). It's like they've designed this to be hosted on a mobo having memory cards without any heat-sink, which is unrealistic and poorly thought IMHO. Consequently, in a dual-channel memory mobo, this cooler won't allow for 4 DIMM of memory but only 2, thus downgrading the mobo to a max. 16Gb of RAM instead of 32GB! I've read that this geometry around the a 1150 CPU socket is not a particularity of the MSI H97 mobo, so no excuses there : -2 eggs.

2- (-0 egg) The little sticker pads on the back plate were useless in my case, the hight of the back plate being a bit higher than the mobo's plate (assuming "hight" is perpendicular to the mobo), but no con here : the shape fits perfectly, so just turn the mobo over with the back-plate under it and then drive the screws in, easy. Of course, if the mobo already sits in the chassis, you'll have a harder time if you don't want to take it out...

Other Thoughts: I didn't need an uber heatsink since this is targeting an H97 (no over-clocking whatsoever, while hosting the new breed of Intel's CPU involving less heat dissipation than previous"tock-tick"). In regards of "benchmarked" results by reviewers, I'm already confident about this very affordable heat-sink to be more than enough for the current system I'm building and its context (my friend don't want his computer for playing games).

I would recommend this heat-sink only if you don't need more than 16GB using one memory bank (not more than 2 DIMMs of 8GB each for a dual-channel configuration), be aware of this.

I've made that friend go through the Newegg's buying / shipping process (1st time he bought "important" stuff on-line), and so far he's very pleased by his experience, kudos to Newegg!

1 out of 5 eggsARTIC Freezer i11 CPU Cooler

Pros: Small, nice compact cooler.
Intel specific.
Delivered on time.
Decent price.
Good mounting hardware.

Cons: Does not support 150W or even half of that.

Other Thoughts: Installed this on a Intel 3570K and 2500K LGA 1155.
The Xigmatek Loki it replaced did better. Zalman finally did the job. There are better choices here at Newegg.

5 out of 5 eggsArtic Freezer i11 CPU cooler review

Pros: Excellent cooling solution. Very quiet and keeps the CPU nice and cool. Respectable temps even under a load. I have used Arctic cooling case fans and CPU coolers on my current build and on past builds and will continue to use them in the future. I highly recommend one of these if you are in the market for one.

Cons: None.

Other Thoughts: My build;
Asus X79 Deluxe MB
Intel core i7 3930K CPU
Artic Freezer i11 CPU cooler
EVGA Supernova 1000 PSU
Asus Xonar DX 7.1 sound card
G. Skill Trident DDR3 1600 (32GB)

5 out of 5 eggsAmazing cooler

Pros: Easiest install I could have ever imagined. some people say the sticky tape doesn't stuck well on the bottom. you don't even need to use it just put the cooler base under the socket and place the mobo on a table and just screw the heat sync in bam done. and the socket 1150 takes the longer screws.

Cons: none absolutely none. amazing cooler.

5 out of 5 eggsJust what I needed

Pros: Overall, a huge improvement over the stock Intel heat sink and fan. Much quieter, and I have yet to hear the fan spin up at all from the lowest speed. I would hear the stock fan spin up regularly. I installed it to blow towards the exhaust fan in the rear of the case, so I'd bet my PC is now better at getting hot air out of the case. The stock fan blew straight down towards the motherboard so there was a fair amount of warm air recirculation inside the case.

Cons: I had to install it myself with some of the limited free time I have :)

Other Thoughts: I've been running a Core i3 with the stock heat sink and fan in a media center PC for a few years. Recently the fan started making more noise than usual. Without checking for clearance I ordered a Hyper 212 Plus, which I had installed in a desktop build and was quite happy with, especially for the price. Turns out the 212 won't fit in a 3U media center case, duh. So I looked for a similar unit with smaller dimensions and this one looked like a good choice at a similar price to the 212. The install went without a hitch, and it is noticeably quieter than the stock fan ever was.

Just remember to be smart in you case choice. With my desktop case I can have both sides off and easy access to the front and back of the socket area of the motherboard by removing 4 thumbscrews. My media center case made the process significantly more difficult. 11 screws to remove the top, 4 screws to remove the cross brace, then I had to disconnect all the cables and mounting screws from the motherboard so I could pull it out to access the back side for mounting the new heat sink.

Swapping heat sinks isn't something you'll do regularly, but the suboptimal access of my media center case turned what could have been a 10 minute process into a 90 minute hassle. But at least this product is working like a champ now. Certainly no regrets from me, other than me continuing to use this media center case with poor access :)

5 out of 5 eggsReally nice CPU cooler

Pros: Keeps my i7 4770K nice and cool. Idles at about 26C, doesn't ever go over 50C even under stress
Easy installation
Inexpensive investment for the benefits it gives you

Cons: Thermal paste instructions are a little weird, but go nice and light with it and it works fine.

Other Thoughts: I'm really happy with this cooler so far. As long as you make sure you've got the fan oriented correctly with the airflow through your case, it'll keep your CPU nice and chilly.
