1 out of 5 eggsUpdated review

Pros: Cooled OK while it lasted. Cheap.

Cons: I removed the heatsink to re-apply the thermal paste in hopes to drop the temps a few degrees. The crossbar nut threads are now stripped out.

I am very careful and always gradually tighten or loosen nuts/bolts on heatsinks as to avoid any uneven pressure.

The threads on the crossbar nuts are simply not built to take the pressure required to hold the heatsink in place.

Do not buy if you plan on removing the heatsink or are worried about the heatsink potentially falling off because of the low quality nuts.

Other Thoughts: I've never had any major issues with other Xigmatek heatsinks, until now.

I have used the SDT-1283/Gaia/Dark Knight on many builds because they cool great and were inexpensive, build quality was always quite good as well.

I have used the Dark Knight for a few years and have removed/reinstalled it on my build at least 10 times without any issues whatsoever.

1 out of 5 eggsBuyer Beware Not Good for FM2

Pros: none at all

Cons: FM2 bracket needs to go back to the drawing board.
the H.D.T. doesn't do its job.
Big Pain in you know what trying to put pressure on the screw crossbar.
My stock cpu heatstink works just has good has this one but more easy to install.
Cpu Idle at 42 Celsius even with Arctic Silver
Huge Cpu heatstink not working has it should
Poor installing instructions
Kinda felt like i almost broke my motherboard

Other Thoughts: First off i install the heatstink but not satisfied with the temps. so i thought maybe not enuff contact between the cpu and heatstink seeing it move when u put a little bit of pressure on it. i took it off, tighten the bracket, put little bit more thermal paste, try to put the last screw on the crossbar with no luck, i check the screw and to my eyes some thread got stripe do to me putting pressure on it trying to screw it on but kept popping off. So i just gave up and got me a Cooler Master Hyper N520 my cooling problem solve.

3 out of 5 eggsDisappointing

Pros: Inexpensive, decent cooler

Cons: I was expecting an improvement coming from the Dark Knight. The temperatures are exactly the same with my i5 750@4ghz (1.35v) (~40c idle, 72c load), idle temps might even be slightly higher. I even added a 2nd high power fan with very little difference (1-2c).

5 out of 5 eggsGood Cooler, Very Quiet, Very Large

Pros: DOES fit an AM3+ socket for any who are wondering, they are the same (in physical shape).
Quiet with low rpm
very effective at keeping cool
not too expensive

Cons: It is a bit hard to get in, but only takes about 5 minutes to have the whole thing assembled and ready for gaming.
It is very large, this was not a problem for me, but it includes the large heat sink + the additional height of the fan (18mm)

Other Thoughts: This cooler is very good at what is advertised, it is very effective at cooling, for me at least, I don't o.c. It is quiet, as long as you change the fan settings in the BIOS, otherwise it will likely run at %100 all the time. I noticed that it wasn't that quiet, but then remembered the Q-Fan control on my Asus motherboard. Not a problem with RAM being in the way, it is about 16mm above the RAM. All I would make sure to do before buying is do a measurement from the motherboard to the side of your case, and make sure it is more than or about equal to 175mm.

5 out of 5 eggsAmazing Cooler

Pros: Amazing cooling, amazingly quiet. I have an i5-2500K o/c to 4.3 GHz. I put this in replacing a Coolit Eco ALC (liquid cooler). The computer is far quieter now, and running Prime 95, the core temps never went over 65 C.

I did add a second fan, which I had lying around. This may have helped its amazing cooling prowess.

Cons: It only comes with one fan.

It is rather large, so make sure your dimensions are okay before ordering.

Xigmatek's rubber fan mounts are not the best.

Other Thoughts: It would be great if Xigmatek included two of their amazing 14 CM fans (see - these fans are amazingly powerful and quiet.

1 out of 5 eggsNOT compatible with LGA2011

Pros: Lovely construction -- looks well built
Right size for my new I7-3930k

Cons: NOT compatible with LGA 2011

Other Thoughts: Upon arrival, the box did not have New Egg's stated LGA 2011 compatibility marked on it. Sure enough, when I went to the manufacturer's website for LGA 2011 instructions, though 2011 instructions were there, it pointed to the use of standoffs/brackets/screws that were not in my package.

Apparently -- as with many other "LGA2011 ready" coolers (check the forums on this) -- it is the right size/specs to support 2011 hardware but the manufacturers didn't put the 2011 hardware in the box. In this case, New Egg didn't bother to tell me that.

So, in a nutshell, I can't mount it. A return is imminent.

New Egg, I understand that some manufacturers don't offer new SKUs for these small changes (leaving two versions of the same SKU on the shelf), but these changes *matter* to your customers. If you get the newer version in with the right hardware, do us a solid and clean out the old inventory or find a way in your system to specify which version is which. You cost me a week I'd like ba

4 out of 5 eggs

Pros: Cools pretty well!
Good if you want a heatsink with some puzzle action.

Cons: Its very large and with the fan mounted on one side it gets in the way of the ram on the motherboard. Had to mount on the opposite side. The fan is a bit weaksauce, it would be a better idea to replace it with one that produces more flow.

Installing took longer than I wanted it to. That was mostly do to the pretty bad instructions which did not state how to tighten the bolts. I spent a good amount of time just trying to build the mount. Mounting this thing was the hardest feat of any heatsink I ever owned. If you tighten the bolts on this thing before you put on the heatsink on the bolts you will not be able to get the bolt close enough to tighten it without extreme pressure.

4 out of 5 eggsDescent CPU cooler

Pros: Descent cooler that has a relatively quiet fan. Looks snazzy.

Cons: Massive in size. Directions are poor and give no advice on tightening. Base isn't perfectly flat but it does keep overclocked 2600k relatively cool. Ran Prime95 for 1hr 4.5Ghz @71*C on hottest core(ambient temp 22*C) . Can't overclock much more than that or it'll hit 80*C. My case has 3 fans.

Other Thoughts: Only recc'd for ATX+ size boards due to it's size. I got better temps turning the fan backwards thus extracting air from the fins rather than blowing into them. 5-7*C cooler on average! This faces the chrome fins towards the cooler(unprotected fin side)
I think you could achieve much better cooling if a faster yet efficient fan is used. This fan is efficient but spins relatively slow and is actually too big for cooler which IMO hinders flow from between the fins.
