Big, Ugly and Cool

Darryl S., Newegg
2 weeks ago
  • Summary: I was amazed at this thing when I opened the box from Newegg. It is a massive cooler and barely fit the case. It was put on an AMD processor that was overclocked to the max and it cooled it down to just above the mid range supported by the chip maker. Since it has the capability to add a second fan, if necessary, I thought it would e a good fail safe unit. As it turned out, I only needed the single fan.
  • Pros: It does its job well and can e upgraded to dual fans, if necessary.
  • Cons: This thing is HUGE! I put it in a mini tower and it was a close fit!

Works great on a non-supported socket!

  • Summary: I purchased two of these to use in a push/pull configuration on my server turned gaming rig. By using the backplates from the previous heatsinks and making some custom mounting brackets I was able to mount these on a socket 771 system. MUCH quieter than the original coolers and they do much better as well. Load temps are way down which is critical as the server CPU's don't take heat well at all. Very pleased with this product.
  • Pros: Quiet, lots of surface area to dissipate heat, fans move a decent amount of air. Dropped my CPU temps by 2-3 degrees C at idle and 10-15 C under load.
  • Cons: Very big. I have a Rosewill Blackhawk Ultra super tower so it isn't really an issue, however, the heatpipes do just barely touch the side panel fan frame. I also had to measure to make sure everything would fit around other components on the motherboard. Also the heatpipes aren't flush with the sides of the aluminum base which leaves small gaps. Hasn't been an issue so far though. Thermal paste most likely filled the spaces.

  • Summary: Used this bad boy in my first build cooling an AMD A10-6800k. I would have to say that this device went above and beyond the call of duty when it managed to keep the CPU under critical temperatures even after I mistakenly forgot to remove the plastic cover from the contact area before I installed it. The A10 didnt even need to throttle down to protect itself. After I corrected my tremendous mistake the unit performed leaps and bounds ahead of any sort of stock cooler.
  • Pros: This is a big, effective cooler. Don't expect miracles, but this is a must if you need some peace of mind in terms of temps. If you need some space filled in your case, this cooler will definitely do that. The option of installing a push-pull configuration is a plus, too.
  • Cons: Again, this is cooler is pretty huge. It only fits in my NZXT Source 210 with the tips of the heatpipes resting against the case window.

Heh, yes, this cooler is pretty huge

Christopher K., Newegg
27 August 2014
  • Summary: As nearly every other review has mentioned: this thing is gigantic. I'd figured I'd be fine with my full-size tower case but it turns out that my case just isn't "tall" enough for this guy, alas! Be sure to measure it out and compare versus the specs. The cooler itself looked extremely solid and well-made.
  • Pros: Real solid-feeling construction, looked well-made
  • Cons: n/a

  • Summary: This WILL NOT fit a micro atx board. I had tried to measure out the dimensions for the board and cooler before buying and it looked like it would be a tight fit, but a fit. Was not the case. The brackets you need to install will not fit due to some caps (At least on mine) by about 1 cm.
  • Pros: Its very well built and sturdy but not super heavy for the size so the stress on the motherboard should be less than others.
  • Cons: Read other

A Must Buy

Cecil M., Newegg
20 August 2014
  • Pros: it works very well and is very quiet, so well i was able to lower the speed of my case fans and now I can hardly hear it. it dropped my CPU temps down to 35c idle and 38 under load.
  • Cons: it's big, it almost did not fit in my Antec 900 case but i knew that before i got it.

What a Cooler!

Steve J., Newegg
14 August 2014
  • Summary: The mounting brackets are rock solid and the sparse diagrams and instructions are accurate. I had to screw and unscrew the screw-spacers into the brace bracket holes before mounting after discovering how tight they were while trying to do it with the brace bracket beneath the motherboard initially.
  • Pros: Excellent cooling. Robust mounting system. Quiet fan. Price.
  • Cons: None.

Awesome! ...but a tight fit

Joseph P., Newegg

  • Summary: This is a big cooler in length and depth, but it is also surprisingly squat and not overly tall, so this cooler is a great choice for powerful, compact builds. Just be sure to do some measuring before you purchase and keep all of your shipping materials when you receive it in case it doesn't fit and you have to return it. If you can manage to plan and fit it in your case though, this is probably one of the best air coolers I've ever used and seen.
  • Pros: Amazing! - Beastly air cooling - Some of the lowest air temps I've ever seen. I'm getting better temps on this than I did with a big Spire Thermax heatsink. I don't know how or why, but I am. - Solid construction - Great quality fan - very quiet on the lower fan RPM's - Comes with separate thermal grease that isn't pre-applied so you don't have to clean off the heatsink if you want to use your own Arctic Silver.
  • Cons: The edges are sharp and can be crushed if you aren't careful! This can also be tricky to install. On my motherboard specifically, with the orientation of the heatsink/fan I needed to use to vent air out of the back of the case, the fan had to be on the memory slot side of the CPU socket. Although everything fit just fine, it was a very tight fit. I had to remove the memory sticks (Ripjaws), attach the heatsink, then put the memory back in. If the fan was 1mm deeper, m...
