Missing parts

Janos D., Newegg
7 July 2015
  • Summary: Purchased 2 of these. In both boxes the above listed items are missing. This is rather disappointing for such an expensive CPU cooler.
  • Pros: Have not used it yet.
  • Cons: Several items listed on the included installation manual are missing: - no thermal compound - no anti-vibration strips - no screwdriver - no fan clips - no short screws

eggsellant

Richard L., Newegg

  • Summary: If you don't have a big enough case this heatsink fan combo could be an issue. I planed for it and it worked great. This is the second one I have bought from this company, and I love their products.
  • Pros: size, and heatsink quality
  • Cons: size.

User Review

Troy W., Newegg
22 May 2014
  • Summary: If I was able to use this product I would have rated it accordingly however the low rating is more due to the product listing since I am not able to use the device as intended.
  • Pros: I was not able to use this heatsink due to the wrong mounting alignment or lack of bracket as noted below however you can tell just by looking at the construction and materials involved that this is a quality heatsink/fan combo. The instructions and supplies included are plentiful and helpful com...
  • Cons: When purchasing this heatsink/fan combo I hastily ordered the item when i saw it was on sale. In the Product title it is listed as "A3 AMD" and NOT "AM3+". This Item will NOT fit on those boards with the included items. This seemed misleading albeit I should have looked closer on the product spec...

Noctua

Nolan L., Newegg
26 January 2014
  • Summary: Seems like a high quality product.
  • Pros: Runs quiet and cool. Even without the included noise dampening power links.
  • Cons: I'm not complaining but these monsters are HUGE. There's 2 fans, 1 blowing into the heat sink, and 1 sucking air out. When sitting the fans evenly on the heat sink the fan can get in the way of other components such as RAM chips. However the fan location is adjustable so if I expand RAM later on ...

Best C32 cooler

Anonymous, Newegg
22 January 2014
  • Summary: Inclusion of the tall hex key is thoughtful. Two of these together on a SuperMicro H8DCL means you'll have to only have fans 'pushing' since there will be no room to mount them if you have the heatsinks mounted inline with airflow (front to back of case).
  • Pros: Very easy to fit once assembled* Fan attachment is simple yet effective (no rubber things to pull through) Heatsink is a thing of beauty
  • Cons: *Attaching the processor brackets (G34 or C32) with the small screws is annoying since they are slick and cannot readily be thumb tightened.

HUGE, but awesome

Ryan F., Newegg
26 November 2013
  • Pros: I have two of these cooling Opteron 4334s and they work great. These CPUs running numerous VMs never get hot.
  • Cons: Very large. Only 3 pin connectors.

Strong CPU cooler but HUGE!!

LOUIS-PHILIPPE A., Newegg
2 November 2013
  • Pros: This CPU cooler simply is AMAZING! Quality is phenomenal and it ships with way too many accessories but I guess for the price tag its alright. Cooling performance is also phenomenal. Under full load on all 6 cores, my Opterons 4334 are kept at around 35C which is pretty low if you ask. The fans a...
  • Cons: The instruction sheet is garbage. Most of the pictures are totally wrong (not showing the proper component options for the socket C32) and it is cryptic to follow. Thanks to my experience assembling computers, I did not use the instructions at all. The thermal paste that came with the heatsinks i...

My second one

Scott R., Newegg
30 September 2013
  • Summary: if they just designed the fins so that the Allen wrench could go through them to the screws, the problem would be solved with minimal loss of cooling (might even help having the extra holes in the fins).
  • Pros: I used this with G34. beautifully constructed (engineering is another matter), flow can be directed in any direction (brilliant). good materials, comes with various resistors for fan speeds.
  • Cons: the one and only con, has always been attaching the mounts to the base - its a total pita. You can barely get the screws in between the fins and the base let alone turn them. When you do finally get them in, the wrench will only turn about 50 degrees before having to reposition it.

It's HUGE

Paul P., Newegg
25 September 2013
  • Summary: I went with two other heat sinks prior to this. The CPU was either overheating or on the edge . Due to this, it caused capacitor whine on those two boards. Now that I have the new board, the capacitors didn't whine and the CPU just flagged overheat in the BIOS. That's not the case any longer
  • Pros: Ok... I've seen big, but this thing requires at least 3U. It is massive, has two fans and it is QUIET. Not only that, it keeps the CPU (C32 4334) below 45C at full tilt. I read a lot of the reviews on this and people couldn't figure out how to put it together? Really? Let's stop being guys and be...
  • Cons: It's massive. The board I have is a dual proc and I'm seriously doubting that when I go to add the second CPU I'll be able to put another of these next to as they will probably hit.
