This is a fantastic cooler with a poorly engineered mounting system.
Fwiw: i am using a 2600k overclocked to 4.4ghz, and was previously using a corsair h60.I'll get right to it: the assembly itself is straight forward, but i'm decking it a star because the mounting system is terrible. I'll get to that in a minute.If the cooler happened to not come with instructions, you could fumble through it and figure it out. The plastic bracket for the back of the motherboard is fairly confusing. The bracket is labeled "intel" and "amd". Don't look at the pictures in the instructions and just look at the thing to figure it out how to mount it. (if you're mounting it on an intel cpu, have the word "intel" facing you if you were looking at the back of your motherboard). As well, the bracket is plastic which is a blessing and a curse. They include two-way adhesive stickers so you can stick it to the back of the board. Metal would be better, but as well heavier and render the adhesive strips useless. After mounting the bracket, you'll need to put the threaded pins through the mounting holes on the bracket, which in turn feed through the mobo. I'd strongly recommend super gluing (or using strong tape) on these threaded inserts. You'll just end up pushing them out when trying to screw down the cooler since they don't really "lock" into anything on the bracket.As for the mounting of the cpu cooler itself...Oh boy...Where to begin...The cpu cooler itself has a metal bracket that you must slide little metal adjuster things on, depending on whether you have an intel or amd board. It's probably the worst designed thing i've ever had the pleasure of dealing with. After choosing amd/intel on the sliders, you clip the bracket onto the cooler and feed screws through the bracket into the previously mentioned pins in the plastic backplate.Those little levers i mentioned above? There doesn't seem to be a way to lock them. It took me (i'm not exaggerating) about an hour and a half of fumbling before i was able to get the sliders to stay in the intel position and the metal pins in the plastic backplate to stay in place before i finally was able to get a single screw threaded through. After that, i was able to (fairly easily) get the other screws in and wrap up the install.If i had to do it all over again, i'd absolutely have a tube of superglue with me to glue both the metal bracket into the intel position, and the metal pins to the plastic as well, remember how i said the plastic backplate is a blessing and a curse? I mentioned the blessing part (adhesive strips), but the negative part is the threaded metal pins...It's super easy to "over-tighten" the screws and the metal pins to pop out of the plastic on the back and just free-spin. This could easily be fixed if antec included brackets for each of the sockets it supports instead of the universal one that is cumbersome and annoying.Performance wise, it cools way better than the h60 (as it should, since the h60 is 120mm vs 240mm)the antec logo on the cpu cooler itself contains a led, which can be controlled by the terrible software that's included with it. The software works, it's just hideous.If you were to start a stopwatch from the time i popped off my h60 and finished screwing this new one in (stopping the stopwatch during times of frustration when i just had to get up and walk away from the thing), it probably took me a little over two hours.Unacceptable in my book, which is why i decked it a star.I would strongly recommend superglue and/or a friend to help. You simply need more hands to hold everything in place while you work.Edit: after writing my review, i looked for other reviews on hardware sites. One of them mentioned little plastic clips that you can wedge between the amd/intel levers so they don't slide. Sure enough, they're in the same bag as the backplate adhesive strips. I'm leaving my star deducted, as the manual doesn't mention these little clips at all. As well worth noting, the pump makes an audible hum while it's running. I tried orienting the cooler a little bit differently (as well as the radiator) and it doesn't seem to make a difference. I'll update if it gets worse/better.Edit 2: the rattling is starting to drive me insane so i opened an rma with antec. Pretty simple. They required an invoice from when i purchased it, and then i had to call into their support line and provide credit card info so they can do an advanced rma. (aka they place a hold on your card and ship one immediately, so you aren't sitting without a cpu cooler while it's in transit. I'll update this with my findings on the replacement when i get it.Edit 3: the replacement i received today seems to work fine. Installation was just as annoying the third time around as it was the first. Now i have to pay return shipping back to antec, which works out to about $17 for the slowest/cheapest via usps (the unit is over 5 lbs.) as well, i have never been able to reproduce the same temperatures i got when i initially installed the thing. I'm running about 5-6c hotter now than when i initially installed the first one. I doubt this is the fault of the cooler, but probably due to poor ventilation in my case combined with warmer temperatures. I'll keep an eye on it.

Good cooler - when you get it installed
The install of this product is a pain. I recommend removing the springs from 3 screws and using them to hold the cooling head on the cpu while you get the 4th screw with the spring attached, then one by one put the springs on the screws and install each one. I'm right now having to send my cooler back for a faulty fan controller causing one of the fans to not spin (works fime when plugged straight into the motherboard). The temps are good but it is loud.

Good cooler, but backplate has a problem.
1250 design problem - the backplate. The thin plastic around the 4 flush nuts is not strong enough to retain the nuts without becoming stripped. The other reviewer's comment about superglue might be a good workaround, to hold the backplate retaining nuts in place. A last retainer nut started turning in the plastic holder while tightening one of the four cooling head mounting screws. There's a 5.5 degree celsius difference between asus motherboard bios cpu temp reading and the antec grid temperature control program, so heat transfer may not be optimal. Antec said grab the nut with a needlenose and tighten the screw, a workaround, but only one edge of the nut is exposed. The retaining nut is flush in the plastic backplate. Grabbing one edge of the nut and the other plastic side, and the nut still turns while trying to tighten. Antec eventually said they would order me a new backplate, but didn't mention how long it would take. I suggested they redesign the backplate to avoid this easy to duplicate problem. The backplate securing method appears flimsy, and it is. I should add that 3 of the mounting screws firmly attached to the backplate inset nuts. Not so with the fourth, and yes, i did follow their instructions in how to tighten the screws. I'm trying to protect a very expensive cpu and i'm just not getting the cooling that i feel is available. Just be careful in tightening those cooler head screws. It's very easy to strip the plastic holding the retaining nut for the cooler head screw. I was careful and it still became a problem.

Perfect cooler

Good cooler so fare
I like its performance. Im running a amd phenom ii x6 1100t processor overclocked to 3.71 gh. While gaming was running at 65 c to 72 c. Now running at 45 c. Big improvement. Installation was ok. Read the reviews on people having trouble with the screws. If you can use the stock amd mounting plate. Theirs screws for both stock and the aftermarket one. As well take the springs off the screws and crush them with pliers than put them back it will make them easier to put in. As well the unit is really big and cant fit into a case very well. I modified may case and mounted it on top. If you don't mind a little noise the pump as a little noisy. Im happy with the cooling performance and the software included. It as well came with pre-installed thermal compound looked like arctic silver 5.

Revision a beware...
Really really want to give this more stars. I am on my second one. Keep getting revision "a" version (second buy) that always ends up with a controller that fails and the fan (either) will slowly stop working, little by little until it just twitches occasionally.Hit up antec, they kept question for receipt, emailed it numerous times. Then they just stopped emailing me.Thanks guys.

Great while it worked.
This worked great for about a day but then i starting getting clicking noises from the pump. It kept my processor nice and frosty, but i've since returned it for a different cooler.Pros: keeps the processor extremely cool and when it's not clicking it's extremely quiet.Cons: a pump malfunctioned within 24 hrs, mounting it to the board was more difficult than some other coolers.
By Hanna Ford
A pain to install, then it doesn't even work right.
Edit: 3/16/15the working fan went out after two days, so now my computer is unusable until my new cpu fan comes in.This cooler was a pain to mount, like most people have said. Then, when i finally had it mounted and turned my computer on, only one fan worked. I guess i should have tested it before putting all that work in. After the hassle that this was, i'm not even bothering replacing it, i'm just ordering something else. I am giving it two stars because even though only one fan worked, it kept my processor fairly cool during none intense applications.

Purchased two of these brand new and both made loud clicking noises when in use. After tweaking with the software and getting nowhere, i looked around online and it seems others have had this issue too. Was unacceptable and had to return.
