Pros: I have AMD Phenom 9850 2.5GHz with stock cooling. I never cared about the CPU temperature since the stock cooling was big, had 4 copper pipes and the base is made out of copper. When I played games in Summer for an hour or more, the computer would slow down and freeze from time to time. Then I went to my mother board website and downloaded the temperature regulator utility and got a reading of 50C CPU temperature in IDLE. Now I know 70C is where I should worry about so 50C is not a problem, but still I did not like it at all. So I bought this cooler and installed it (1 hour process). When I turned on my computer and went to the BIOS the CPU temperature was 25C . I wanted to get my eyes checked by the doctor but I asked my bro to take a look at it to verify that my eyes were not deceiving me. Then I went to windows and the temperature went down to 23C at IDLE and the operating system is running more stable with no freeze up in game. How could a simple cooler do so much!!!

Cons: Installation is a little hard but it's fun. For AM2+ I started from the Heat Sink then worked my way to the mother board. If you have extra set of hands then it becomes easy to install. You will have to take out the entire mother board in order to install this heat sink. Also if you want to upgrade your CPU then you will have to take out the mother board again for AM2+ Depending on your case you may not be able to close it if you have a side fan (Full Tower). I took off the side fan from the inside and installed it to the outside and the problem is solved :)

Overall Review: The heat sink secures very nicely and tight. After you install it you get the secure feeling that you can not take it off easily unless you take out the mother board. Since its all screw in, you get to choose how tight (making it very tight is not recommended) or loose you want it. And the screw are long enough to reach every ends. The Arctic Silver thermal past is not high quality (not Arctic Silver 5) but hey 23C is more then what I asked for from air cooling (I am not complaining). I most definitely recommend this product because its worth the effort after seeing the result and the price is just right. [I wish newegg.com allowed posing images with feed back]

Pros: CHEAP! Works very well...

Cons: Instructions, junk thermal compound.

Overall Review: The Vigor Monsoon III was sold out when I purchased this item, I'm glad I bought it. I used Zalman STG1 instead of the junk that came with this product and it keeps my i7 920 at 30 degrees celcius while idle. The instructions were a little funky, but the diagrams were dead on, this helped tremendously. Has great clearance on a Gigabyte GA-EX58-UD4P, all memory slots are still useable. Buy this product and you won't regret it.

Pros: very nice heatsink, very quiet especially when compared to the old stock cooler, looks nicer too. compatible with almost every socket. picture instructions are very easy to follow. could pass as passive cooling, but i'm using the fan at 600 rpm just because it's included, barely audible

Cons: almost did not fit in my case, it has less than 1 cm of clearance from the side panel. if you put the fan over on the RAM side, you will block out at least 2 DIMM slots. The heatsink is raised high enough that you can still use the slots, but you wont be able to install any fancy heatsinks on your RAM. fan mounting brackets looks very flimsy but it gets the job done

Overall Review: have this installed on an asus m4a79 deluxe over an amd phenom and temp never goes above 30C, but then again i haven't run any stress tests yet. before i bought this I knew it was going to be big, but this thing is HUGE, newegg photos do not do this HSF any justice fan mounting brackets looks very flimsy but it gets the job done like everyone said already, installation was a pain, but when you manage to get it right, you will feel a new sense of pride. Good job Scythe

Pros: IT'S BIG. It actually cools quite well. Dropped about 10 degrees celsius, when I upgraded from a cooler master hyper tx2. The average temp when under load is about 53 degrees. Back plate is a definite plus. I strongly dislike pushpins for two reasons: 1. It is hard to push push pins in cramped cases. 2. Back plates prevent motherboard flex. The included fan is nice in the fact that it is pwm, so I can control the fan with software.

Cons: IT'S BIG- I was worried about clearance issues, but everything worked out fine. Not the installation process - In order to make installation a lot easier follow these tips: 1. Place the cooler upside down on the table 2. Place the box that the cooler came in about 6 inches apart from the cooler. 3. Carefully lower the upside down motherboard onto the cooler and the box. The box should be positioned near the edge (usb headers, front panel headers, etc.) of the motherboard so that it lies even, thus allowing you to place and tighten the screws.

Pros: I bought this in conjunction with an AMD Phenom II X4 940 Deneb 3.0 GHz quad core, it was a pain to install but it was so worth it. First off, it's huge so there is a lot of area to dissipate heat. Secondly, the fan can be mounted on any said facing any direction. This thing keeps my processor so cool it's ridiculous. The ambient temp in my room is well below 20C and the processor was at 16C when I first turned it on and booted into the BIOS and remained there for a few minutes. I booted it up and everything worked perfect. Comes with all the tools needed even thermal paste even though I used arctic silver 5 instead.

Cons: It's a pain to install. If you're upgrading you have to remove the motherboard and add a custom backplate and screw it in. Very tedious work but it's interesting and very very worth it.

Overall Review: It would be nice if this were to come with a clamp easy install but since my processor is idling between 15C-25C I'm not going to complain about the 1-2 hours of work it took to install. Fantastic heat sink, it's huge! HUGE!!!! This thing barely fits in my ATX Full Tower case but it provides FANTASTIC cooling.

Pros: Excellent cooling, it's been tested against the best and it comes out on top (except for the new 3 fan Thermalright IXF-14 - check out xbitlabs . com for a review of some 1366 coolers).

Cons: Installation is a bit involved, but it's worth it in the end!

Overall Review: I'm running an Asus P6T with an i7 920 and used this cooler - OC to 3.6Ghz doesn't push it more than 65 C at max load!

Pros: This cooler took the temps on an ASUS P5-GDC-V (Socket 775) from 60C - 69C down to the low to mid 40's. Excellent design when you consider how many motherboards it will fit. The bolt on design beats the hell out of those lame plastic insert designs.

Cons: Not really a con but as some have stated, this cooler assembly is huge, is not your typical install and may be a challenge to some.

Overall Review: I acquired this mobo with a 3.6 Prescott from a guy who bought it and could never get it right. I remembered reading about how Prescott cores ran really hot. After installing and testing I found temps over 69C. I took a chance on this cooler. It really does the job - No more lock ups or random re-boots - Thanks

Pros: Great performance. I used to get 95C load on the stock cooler. I now get 73C. That's a serious temp drop! Those temps are both with my i7 920 clocked at 3.9 GHz on stock volts. I couldn't go any higher on the stock cooler, but with this cooler I can probably hit at least 4.2. Extremely low price, especially considering how other top-tier coolers easily cost twice what this costs.

Cons: The installation is ridiculous. Dumb, dumb instructions with the washers. Install the screws a quarter of the way into the backplate first, then put the washers on to the screws. Requires motherboard removal, unless you have a backplate cutout in your case. Also, it requires removal of the CPU retention mechanism, which makes you a bit nervous about dropping the screwdriver into the pins...

Overall Review: The cons aren't so bad as they seem, I got the cooler installed in under 20 minutes and the performance was great. All for under two dubs!
