5 out of 5 eggsHuge but cool

Pros: This is a well built cooler with a very quite fan. I installed this on an i5 2500K with and MSI P67-G43 motherboard with all RAM slots filled with G. Skill Ripjaw X modules with the tall spreaders and even though the fins hang over the first two slots they clear the RAM coolers by a few millimeters. It's a tight fit but it works. I have a Cooler Master HAF 912 case and it fits just fine with still bit a room for excellent air flow.

Cons: Installation is fairly simple, but getting the screws to thread into the backplate bolts is a bit of a hassle. The included spanner tool works just fine but requires more effort and time than using an ordinary screw driver, but unfortunately due to the size of the cooler it is required to use the included spanner tool. This will definitely require you to remove the motherboard from your case for installation. Any motherboard headers near or under the cooler will require special tactics to plug, such as case fan headers and the CPU power port.

Other Thoughts: I knew the installation would be tricky going into it, so I wasn't caught off guard at all. If you are patient and willing to take the time to install this cooler then I would highly recommend it. Smaller coolers such as the Cooler Master Hyper 212 are definitely easier to install. With a mail in rebate this is an great deal for $29.99 after MIR, but at full price I might have looked elsewhere.

5 out of 5 eggsGood

Pros: This seems to be a great cooler. It's built well and is reasonably priced.

Cons: none that I see.

Other Thoughts: It will not fit in a corsair air 240 case. (no fault of the cooler)

2 out of 5 eggsGreat price, poor design.

Pros: Six copper heatpipes.

Polished Copper base.

Aluminum cooling fins are about as large as could reasonably fit inside a mid tower case. Fins are raised just high enough so as not to block low profile memory with a few mm clearance.

The cooler is designed for a lot of different chipsets for both AMD and Intel. Instructions for 1155 work for installing on 1150 boards.

Cooler arrived undamaged, no bent fins or visible quality control issues.

Cons: The copper base was slightly tarnished when it arrived. Zalman should have installed a sticker on the base to prevent contact with air until just before installing the cooler.

Installation is hard. For my motherboard, the MSI Gaming 5, I could not install one of the retaining screws without removing one of the factory installed power distribution heatsinks. The instructions in the manual appear to be written by someone who is not a native English speaker. The diagrams are small and not sufficiently clear.

Mail in rebate was declined despite including all documentation, so this cooler cost me $20 more than I expected.

The provided fan is 135mm and has no bracket! When the fan is running at full speed, you can feel the air escaping through the open ridge and not through the aluminum fins. This is a poor design choice.

After installation, CPU temperatures still hit as high as 99C and throttled when running Prime95. Not sure if this is any better than the stock Intel cooler.

5 out of 5 eggsgreat heatsink

Pros: Price is really good

Cons: design is somewhat poor. Heatsink is so huge, my hand is too big to tight screws. I have to take motherboard out to install the heatsink. But for this price I don't think it is a con.

Other Thoughts: I paid $30 for the heatsink. Took me 1 and half hour to install it. I am satisfied with the performance, now my 4790k work under 70C at full load (was 78% with my old cooler master).
Some reviews said the screws are too short, it is not true!!!
If your screws are too short, you must assemble the back plate incorrectly.

1 out of 5 eggsHarmfull Heatsink

Pros: Does a very good job for cooling.

Cons: Very hard to install due to large size. The space left beside RAM is 1 mm or less. Got problem on startup of my mobo because the screws were too tight. Nightmare if you have to install this twice.

Other Thoughts: Would not buy this again. Get another heatsink model.

5 out of 5 eggsWhat more could you want for 10 bucks?

Pros: 10 dollars after rebate so as long as I get the rebate I'm more than happy despite any cons. This thing is HUGE. 6 heat pipes and an all copper contact. Free shipping took 48 hours. Others have said this thing keeps up with water coolers and I believe them it is a MONSTER.

Cons: May be hard to install because of the size and other people have had issues with the hardware. 950 - 1350 RPM for the fan is a very small range and probably negligible but I will most likely be putting a different fan in there anyway. The fan design is kind of poor because it does not force air through the cooler. Even with something like a 212 you do not get an amazing seal from the fan to radiator and the air leaks are not helping your cooling but the fan in the middle of this thing is a joke but I imagine due to the size of this thing you could go fan-less and as long as you don't overclock you will probably keep pretty cool.

4 out of 5 eggsMassive, not easy to install, cools well

Pros: Installed on my 125W Q9550 in a cheap Thermaltake V3.

-Great value, $10 after rebate with free eggsaver shipping: recieve it in just one day, surprisingly

-Cools very well. 33C at idle, comparable to the much noisier stock-style 92mm CoolerMaster it replaced

-Much quieter than the Intel Stock fan

-Very light weight for its size

-Full copper contact surface

-Not TOO tall, fits the Mid ATX V3 very well, height-wise

Cons: -Massive. Truly a huge cooler at 160mm across.

-A major PITA to install. Removed mobo, from start to finish it took about an hour to get everything lined up correctly and torqued down. Don't waste your time trying to install it without removing the mobo, seriously. Even in a full size ATX case.

-The install instructions were fairly well laid out, but there is an error. If installing on an LGA775, do not use the rubber support on the mount, just the double sided tape. Otherwise, the bolts are not long enough.

-I'd recommend using your own thermal compound of preference over the included stuff.

-Did I mention this thing is gigantic? I have it positioned on my MSI mATX venting upward instead of out the back. It is about 1, maybe 2mm away from making contact with the top of the case and wouldn't fit any other way. I also had to relocate the rear fan. But it does fit.

Other Thoughts: Overall, this is a great cooler, and I got it for a phenomenal price. It's very well built, if not terribly well designed for ease of install.

3 out of 5 eggsInstallation is just pain

Pros: It's huge and comes with 6 heat pipes
It's 10 bucks only
It does with it does. 5~7C lower than Hyper 212 plus.
212 plus:
1045T 3.2Ghz. idle 32. Loading: 55C
idle 33. Loading 47.
Still quiet .

Cons: The fan is not controlled by the MB quiet fan function no matter how hard I try to adjust it.
That thermal compound sucks.
Use Arctic Silver 5 instead.

Other Thoughts: I wonder what kind of school the designer went to.
Or may be they hired a "smart" person to do the job.
I mean, did the designer ever try to install that thing by himself? Did he ever try to install other brand HS? Really?.
Difficulty on screwing it right: >LV 90000
Lots of people and review demonstrated it's performance is worst than a 4 Heat pipe 212 EVO. Probably because of the installation. It is very hard to align the base hole with the HS and the pressure is just not right.
But if you get it right, it works well.
