5 out of 5 eggsVery good heatsink

Pros: Destroys the CNPS8700, CNPS9500, CNPS9700, Tuniq Tower 120, AMD and Intel stock coolers, and basically everything else I've compared it against. It was a good 5-6°C cooler than a Phanteks PH-TC14PE, when tested with the same fans on both heatsinks. I have used this heatsink on a lot of different platforms (AMD sockets 754, 939, AM2, AM2+, and AM3) (Intel sockets 775, 1366, 1156, and 1155) and I have never been disappointed by the performance. Various different versions of mounting kits, that improved on older versions.

Cons: Wire fan clips require a bit of fiddling to attach, and have a tendency to fall off if you put them on before you mount the heatsink to the processor/board. Original AM2/AM2+/AM3/AM3+ bracket is difficult to mount with and can only mount in one direction, thankfully the second revision of the AM2 bolt-through kit is considerably better and allows mounting in multiple different directions. Socket 775 also has two versions of mounting kits, one is a X-pattern mounting bracket (revision 1), and the other is a spreader-bar that mounts across the heatsink and attaches to two bars you mount to the motherboard (revision 2). It's nice to have the choice in which one you want to use. There are some better heatsinks on the market now that use newer technologies, but they are also considerably more expensive. The Silver Arrow SB-E Extreme did beat this heatsink by about 2°C in my testing.

Other Thoughts: I'm really glad that Thermalright made newer revisions of mounting kits to support newer platforms (and older ones in the case of 754/939). It's nice to know that if when I'm swapping my heatsink to a different platform and I don't have a mounting kit for the given platform on hand, I can probably find one for sale in a store or online somewhere.

5 out of 5 eggsdestroys the hyper 212+

Pros: I was getting 100c at 1.55 volts on my 2600k on the hyper212+.
I thought I installed it wrong, but I made it as tight as physically possible, even used the side of my case additional pressure, and laid the case on its side and still didn't help.

The thermalright ultra 120 extreme at the same settings?
67c on load

Cons: the mounting system sucks, but you can buy the vx vtk II and it fixes it. 20$ well spent

Other Thoughts: amazing

5 out of 5 eggsNice

Pros: solid, fins don't actually bend, unlike other coolers

34 C - 45 C range, gets a bit hot in my room at night with 4 computers running all day

I took my time putting it in, packaging is simple and nice.

Cons: the process of adding the fan with the clips had me for 10 mins.

Other Thoughts: I have the air shooting straight through this and into my PSU fan, then out. Other words air going up and taking a hard left, it helps out.

Lost the rubber strips to sit the fan in, it makes no difference though. I also slightly bended the clamp to "hug" the heat sink more. Once you have it you'll understand why, but you don't have to though.

shame of me not getting this off Newegg, but it was out of stock at the time, and I sav'd a few bucks. Very nice cooler

4 out of 5 eggsGood heatsink, but...

Pros: Effective cooling provided a well-known manufacturer. Very good quality build and good engineering.

Cons: In the last week I bought two of these. Thermalright STILL has not fixed the quality control problem of not ensuring a flat heatsink base. Both of my Ultra 120 Extremes required lots of sweat, wet-dry sandpaper, and time time spent lapping to get the heatsink bases flat. Come one Thermalright! Your good reputation won't last forever if you keep doing this. These complaints are nothing new. Also, Thermalright needs to work on the screw-in retention clamp. It is just not rigid enough and does not put enough downforce on the heatsink base-CPU.

Other Thoughts: If you think this heatsink is "huge," you obviously have not used top-tier heatsinks before that are designed for high performance CPUs. As far as size and weight go, the U120E is nowhere near the largest or heaviest. I'm getting about 2C cooler CPU operation with the U120E compared to the Tuniq Tower 120; 3C better compared to Zalman 9700NT. System used for temperature measurement/comparison: Abit IP35-E, Intel Q6600 at 3.5GHz (1.1GHZ overclock) running at full load, very well ventilated case.

4 out of 5 eggsCooling Performance

Pros: Mounting is solid and secure

Cons: Size, Weight

Other Thoughts: Just wanted to explain a little about this thing. Yes it is huge, which can be a pro or a con, depending, but if you buy this you should already know that. Taking this straight from the box and attaching a 120mm Panaflo to it gave a drop of about 8 to 10 celcius over a Zalman 9700. With the cooler lapped, temps dropped another 8 to 10 degrees. With the processor lapped, temps dropped another 5 or so degrees. A 5000+ Black Edition overclocked to 3480MHz and running below 27C idle, is quite an achievement for air cooling, and in turn, this cooler paired with a good fan and some time and knowledge, outperforms or matches some water cooling setups that could be 4 times the price. For $100 or less, this WILL surely make your temps drop significantly keeping on par with water setups for half (or more) the price.

5 out of 5 eggsWow

Pros: Wow this thing mounts on nice and tight... Way more secure than stock intel HSF.
Keeps my O'C E8400 at 42C full load. 30C idle

Cons: It doesnt make my house cooler!

Other Thoughts: I got a nice 3-speed variable antec case fan... when adjusting the speeds you can see the temps lower in speedfan.

5 out of 5 eggsInsane Cooling

Pros: This is slightly smaller than the Vanessa cooler on my old system yet it does a phenomenally better job.

Cons: The fan clips are a bit finicky

Other Thoughts: I have a Q6600 G0 stepping OC'd to 3.005ghz (25% overclock) and the cooler holds the idle temps down to ~32C and the load temps to ~47C
