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

4 out of 5 eggsSupreme air cooling, but not a free lunch

Pros: The results speak for themselves, at this moment this is the premiere air-cooling solution. You simply can't get better results without moving to more "exotic" methods. Well constructed and visually appealing. Who would have guessed that a couple of extra pipes could yield such an improvement over the non-Extreme version?!

Cons: At $90+ after adding a quality 120mm fan and some AS-5 you're getting into the price sphere of some decent water-cooling solutions. The absolutely *massive* size and weight demands a large case and some "shoe-horning." Once your case/mobo/CPU are upright you swear this thing is going to rip the socket right off the motherboard. There just has to be some "gaping" with on its side. Fan clip system looks cheesy, but seems to work satisfactorily. Fairly difficult and time consuming to install properly. Questionable reward for the size/weight/price penalty when all is said and done. I could not recommended this for the casual user/OC'er.

Other Thoughts: With the introduction of a number of excellent liquid cooling solutions so close to the price of this HSF I really question my decision to use the TR120x. That said, however, I'm 100% satisfied with the performance, as their simply is not a superior air-cooling solution on the planet at this time. It's mammoth, can be (and was) difficult to install, costs close to $100 once you factor in a quality, matching fan, appropriate interface paste, and shipping, and demands a LARGE case with meticulous attention to detail during installation. I *think* I would opt for water if I were to do it over again, but the potential of pump failure has always been my concern. If you want to stick with air, and can live with the negatives, the TRU120x *IS* The Big Bad Wolf. Period.
