XIGMATEK Aegir SD128264 Mega Killer Double HDT 120mm Long Life Bearing CPU Cooler Dual Fan LGA 2011 I7 i5 775 1155 1156 1150 Haswell and AMD compatible

Pros: It looks like a decent cooling setup.

Cons: Newegg lists it as compatible with 2011. On Xigmateks site it has instructions for LGA 2011. However the cooler I got must be an early model as it does not include the screws listed on the instructions for LGA 2011 mounting. I've emailed Xigmatek to see if they will just send me the required screws. If not it's going back to newegg, and I'm going to get something else.

Overall Review: Beware, even though it's listed as LGA 2011, Newegg may send you one that's not LGA 2011 ready. (Even if your order contains an LGA 2011 mobo and cpu, common guys!)

Pros: * Fits in a Cooler Master HAF 932 Advanced on an EVGA Z68 For The Win mobo with Gskill Ripjaws X RAM with push-pull fans; PLENTY of room between heatsink top and case side *CPU idles in low 30s and manages up to mid-40s during load. * Includes Xigmatek brand thermal paste * Push/Pull possible - I use Cougar 120s with PWM * Stout mounting system with backplate - all plates, mini-wrench and nuts included - though I ended up using my own rachet set * Installation made sense - dont know why people seem to have issues with it * You can install this without a second pair of hands unlike other CPU coolers I've seen * Comes with eight rubber holders for two fan installation

Cons: * Fins are a little delicate around the edges, particularly where you will be fitting the rubber holders in for the fan so you WILL bend some of these edges in the process (no biggie though) Aegir JUST fit onto my EVGA board (east-to-west orientation) but it rests on the NB heatsink and the fan touches up against first RAM slot (without pressure though) - all works and I can use all four slots. Remember to measure highest thing on mobo - mine was NB heatsink at 41mm and RAM (40mm on own, 42mm when installed) - so the bottom fins clear it. This thing sits about 36mm from base of pipes to bottom fin but is narrow enough for E-W placement and the mount had some wiggle room to it, allowing me to move it away from the RAM some, then I just fit the push fan between the heatsink and RAM - I actually use 2 x Cougar 120s in push-pull and keep the Xigmatek as a VGA cooler. It helped me to get the mobo first to have my measurements made, then got the cooler.

Overall Review: Had to reseat four times to get temps just right - thermal application that worked seemed to be two less-than-pea-sized dabs on inner most pipes (four are exposed); Arctic's "tinting" suggestion on their site proved a real mess; went with the Xigmatek paste myself after clean up. Aegir is certainly not a water cooling system or a Noctua but it seemed to score well enough in all the CPU cooler reviews I've read - I researched coolers for a week before settling on the Aegir. To the guy that fried his mobo and all the people razzing him, I read that the first Aegirs shipped with a different bracket that did not have the black padded backside - so shorting was possible! Once alerted of the issue, Xigmatek engineered a new bracket which we are all now using. I assume he used an original bracket then judging by his tech level.

Pros: This is a great heatsink! I replaced my stock cooler on my i5-2500k with this monster in my NZXT Phantom case(yes its huge!). I could barely close my side panel door because of my mounted 200mm fan and this heatsink. Lets cut to the chase and show some real numbers using Prime95 and RealTemp 3.4 on Windows 7 64-bit. -Stock heatsink and fan look like this at idle temps 29C 33C 31C 29C -Stock at full load 74C 78C 79C 76C With this new heatsink and fan -Idle temps 24C 28C 26C 24C -Full Load 54C 60C 61C 56C AMAZING EH? I couldn't believe it either.. but its true!

Cons: It was a little bit of a pain installing. However, the instructions are very clear on how everything comes together. Maybe it was just me, but even as big as my case is it was all pretty snug. It comes with one fan with an optional push fan you can purchase to put on the other side. So I bought an identical fan so I could have the push and pull air combination. My second fan sat right on top of one of my RAM sticks. Not too big of a deal but you better have plenty of room for this guy cause its going to use everything you got. My ASrock z77 isn't necessarily a full-size ATX either.

Overall Review: As I mentioned earlier I installed an additional fan so I could have one on both sides of the heatsink. Not sure I needed it but it surely can't hurt. They provide the extra screws in case you choose to do so.

Pros: This is a great cooler. The design is good, it have a lot of cooling power. The mounting kit is well thinked and it secure the beast perfectly on the board. I bought it to cool my FX-8150 8-cores 3,6GHz cpu, and i'm able to push it to 4,6ghz with a little margin for the hot days that are coming this summer. This is great as i was using a water cooling system that i made myself that i used for my 3 past computer, and this time it was barely able to withstand the cpu at standard clock; this cpu make a LOT of heat. I almost always have AMD cpu in my machine, so i'm used to the heat that they generate, but not till i buy this one. So if you want extra cooling power, this cooler is for you.

Cons: When you will install the backplate to the motherboard, make these 2 step test that will spare you some diagnostic hours. First, install and secure the backplate to the motherboard with the nuts. After, take a look at the backside of the motherboard, in the rectagle shaped hole though the backplate. The little smd capacitor may be touching or be near to touch the backplate. If the space between the caps and thye backplate is less or equal to 1 millimeters (3/64"), then you will need to remove a mm of material on each side of the plate before installing it. The reason for this is that when you will install the cooler and you will secure it by thightening the hex nut on the other side, the board will bend a little bit, and if you don't remove some material, the backplate will make contact with the caps, and the computer won't boot, or will fry. So take great care before the final assembly. My board is an ASUS M5A99X-EVO. It may not apply to all boards, but be cautious and it will pay.

Overall Review: I don't have enough place in the Cons too finish what i have to say, so i will write it here. I have also one things that i want to say that made me a little angry. I work as assembler/welder, so i'm used to see metal of all kind. When i saw the base of the cooler, i founded that the base was cut with a saw, but was not finished in any way! The finish is very coarse... For a cooler of this price, this is totally unforgivable... So if you want maximum performance, you will need to sand, and polish it before the mounting... You can mount it without finishing it, but you will need a lot of thermal grease to make a good fit, and it's not a good thing.... So this s a very good cooler, but that have some flaws that need to be corrected in future productions. The overall experience for my first newegg buy was great, the shipping was made 1 day after the buy, and it arrived here 2 days after. So 5 eggs to Newegg!

Pros: 1. Very light weight 2. Very good performance overall temps are in the sub 30C. 2. Fan mounts are unique 3. Install was Amusing (see cons)

Cons: 1. This cooler because of the AMD mount holes required modification using a Dremel to fit the ASUS P8Z68 DELUXE/GEN3 LGA 1155 Intel Z68 Board. In short the AMD mount holes for the rear plate had to be cut off and ground down as they struck a mounting screw on the asus board, causing the cooler not to seat properly. The screw was located out side of the Intel mount are but in the exact area where the metal mount fin for the amd hole was. 2. The second major problem came when once i got it to seat right the barrel screws in my kit were not threaded correctly. I had to re-drill 2 of them as the threads on the bottom were malformed. 3. The fan shipped with my cooler had a loud bearing wine to it, so I swapped it out with a diff fan I had on hand. 4. There were 2 sets of instruction in the box, one for a cooler that was an older model (i guess) and one for mine.

Overall Review: The rear plate required an additional modification to fit the Asus board, I blame this mod on Asus more than I do XIGMATEK, I had to remove some foam to clear another mounting screw. However this screw was in the Intel mounting area, Asus should not have put it there or made it thinner. Overall, I love the cooler its performance is excellent and i love the fact its ultra light. But some of the problems I had could have been avoided. Instead of making a universal plate they should just have 2 plates, one intel, one amd. The amd mounts on this dual intel/amd plate effectively set you up for not having an Intel compliant cooler for an Intel install, as there in vastly different positions. It also would have been nice to have a few extra screw parts to avoid the re-drill. And the fan, well its a good thing I have many fans on hand. In short it cost me nothing to fix these issues but the kit was a disappointment for its install and any cost associated with the fan

Pros: Cools CPU effectively Bottom is smooth & flat even with direct contact heat pipes Very secure mounting mechanism Installation very straightforward Big- but smaller and lighter than many

Cons: Intrudes on RAM slot one on my ASRock P67 Pro 3 ( a "value" priced motherboard. It would be possible to overtighten the mount on the CPU

Overall Review: I tried overclocking my Intel I5-2500K to 4Ghz with the stock cooler and after only a few minutes some of my cores were reaching into the 80's. I decided the stock cooler was insufficient. I started shopping around and purchased this cooler after seeing the review of it on FrostyTech.com, where it received an excellent rating. I am very pleased with this cooler. The intrusion on slot one is not an issue for me, as I was already using only slots 2 and 4. If this were an issue, I could mount the fan on the other side of the cooler in a "pull" rather than "push" configuration which would allow clearance on slot one easily. This heatsink also supports dual fans in a push / pull configuration,although it only ships with one fan. The review on Frostytech was based on the single fan in a push configuration.

Pros: I hope Xigmatek beings the Aegir SD128264 back to the U.S. as they claim it is still available in some other markets. I have used this HSF on an overclocked FX-8350 running @ 4.7 GHz. 24/7 for well over a year and it is by far one of the best HSFs ever offered for sale. Independent scientific cooler performance testing by numerous reputable industry sources confirm this. Needless to say it out performs most closed loop liquid coolers also while costing only a fraction of the price. Newegg's price was running around $60 before they sold out. That's a very good price for a top of the line tower cooler that can handle seriously overclocked FX processors. Most of the other top HSFs are in the $80-$100 range.

Cons: Not many cons to mention other than Xigmatek's e-mail response is very slow. The product itself is top quality however and highly recommended if you can find it. Lack of current availability in the U.S. would definitely be a "con" though.

Overall Review: A lot of technically challenged people have been duped into buying closed loop liquid coolers because they haven't bothered to actually check CPU cooler test data to see how poor most closed loop coolers are in comparison to a quality tower HSF. What's really amazing to me is the people who pay more for a closed loop liquid cooler and end up with an inferior cooler over a lower cost HSF. Why would any educated person do that? The other issue that strikes me as down right technically ignorant is introducing a liquid cooler inside a PC for cooling purposes when a HSF works as good or better, costs less, is as quiet or better and a HSF never leaks coolant to damage PC hardware as liquid coolers have been documented to do. If you haven't read owner comments at the liquid cooler forums like Corsair, do yourself a favor and educate yourself. It's a shame how many people are easily deceived by advertising hype and that they never stop to check the facts until after they have a significant issue with a poorly designed product.

Pros: It works very well if you manage to actually install it. Keeps the CPU cool and the fan is very quiet.

Cons: I have DX79SI and if that's what you have I would not recommend you buy this. It will be a huge pain to install it. The instructions are TERRIBLE. First of all let me save you some trouble if you don't listen to me and get this anyway. The LGA2011 instructions were not included, and I had to look them up myself, and here they are: http://www.xigmatek.com/product.php?productid=99&type=support Notice how it's very hard to read them. Then which one is it Xigmatek do I have LGA2011 type 1 or LGA2011 type 2? I had type 2 which I figured out through trial and error, very irritating. Then, because this thing is so huge I had to hit it with a hammer to bend some of the fins so that they don't hit the RAM (my ram has heat spreaders which make it a taller and they were hitting the heatsink). Then, when you finally figure out how to set it up, it will be extremely difficult to tighten the screws because of maneuvering room.

Overall Review: If you like overcomplicated installations, and want a very decent and quiet cooling solution than this is for you. If you have X79 chipset my advice is to got with a PHANTEK solution because those were designed specifically for x79. Sure they are more money, but I am guessing they aren't as annoying to install. I didn't want to give this 3 eggs because I believe for other boards this may be a good cooler, and if you do get this to install it works very well.
