Not getting the performance promised

Raphael P., Newegg
11 February 2012
  • Summary: I upgraded from a brevious build to a socket 1366. I had bought this Noctua cooler for a core duo system, and it worked fine. Upon finding out that I could order a mounting kit to use my cooler with new mobo, I contacted Noctua to order kit.
  • Pros: Build quality, amazing silent fan, mounting system is easy, fantastic customer support. Asus P68d Premium can fit all ram slots and there is good clearance everywhere.
  • Cons: In my case, not getting the performance others are raving about.. Hence teh 3 stars.. Asus P68d Premium can fit all ram slots and there is good clearance everywhere.

Perfect Fit!

Anonymous, Newegg
8 December 2011
  • Summary: If you are buying this product it's because you have an LGA1366 Xeon 5500/5600 CPU. Please take the comments from people with i7 processors with a grain of salt since these coolers were designed specifically for Intel 1366 Xeon's.
  • Pros: Perfect Fit: 1. In my case (HAF 932: Clearance on side case fan by 1 inch) 2. For my CPU's (Dual Xeon 5620's) 3. For my RAM (KVR1333D3D4R9S/8GHB)* 4. For my cooling needs** 4. For my lifestyle (Sysadmin) * The fans to have to be removed from the heat sinks in order to get good clearance on the sl...
  • Cons: I could see you having clearance issues if you had those RAM sticks with the crazy extended heat dissipating fins, depending on where your RAM banks are in relation to your CPU.

Noctua Devotee

BURK S., Newegg
24 November 2011
  • Summary: Would buy again with certainty. Will probably buy newer versions with 140mm fans or something for next system, but the one I have I love still. If it fits the system this is a superb cooler.
  • Pros: LOVELY and QUIET!! I have owned http://www.newegg.com/Product/Product.aspx?Item=N82E16835608002, which appears to be the identical older model of this fan. IT HAS BEEN AWESOME for years now since 6/3/2009. I am a Noctua convert after using. I find the users here that have knocked the product have...
  • Cons: None for me.

OK but not great

Anonymous, Newegg
25 July 2011
  • Summary: The compatibility is sketchy at best but this seems geared towards a Xeon and did not perform well on my i7. When I first seated it, I was getting temps of 49C at idle. I scrapped off the Noctua thermal material and applied some Arctic Silver and tried it again. It dropped to 46C.
  • Pros: Nice looking, good finish and quality, very quiet fan, nice dual fan capability, fits nicely on an Asus Rampage Formula MB (capacitors usually get in the way of other coolers). Generous amount of decent thermal paste.
  • Cons: Confusing clip for fan, poor documentation (for fan attachment). Look at the website pictures for a clue at how to clip the fan on. Hard to get to the bottom of the fan clips when installed (required, for me, long needle nose pliers). Poor performance relative to other heat sinks, expensive for t...

Nice

Anonymous, Newegg
23 July 2011
  • Summary: Very big. Its hard to tell in advance whether this will fit in your case. It overlaps the memory in my case, but it is high enough up that its ok. It also comes within an inch of the side cooling fan build into my case, so make sure you case is tall enough.
  • Pros: Very cool. Very quiet. Works well. Includes thermal paste.
  • Cons: Size: but if you want this much cooling of this type, that's kind of inherent.

If yoru target is a Socket 32, don't bother

Joseph M., Newegg
19 May 2011
  • Summary: For $75, I expect it to work, and be tested.
  • Pros: Quiet operation
  • Cons: You need to make sure your RAM does not have cooling fins, otherwise they may not fit on some motherboards. I bought it for an AMD socket C32, but I had to re-engineer the assembly. It's supposed to screw into the CPU anchor, but the screw does not reach. I tried applying a vise to the spring, bu...

Amazing temps. This product delivers!

Anonymous, Newegg
5 March 2011
  • Pros: Like I said in the title, I'm getting amazing temps on max load than I had gotten with my old intel stock heatsink. It's a huge change. Heres the comparison Intel Stock idle: 45C load: 70C Noctua idle: 29C load: 40C This is a must have!
  • Cons: ***THIS DID NOT COME WITH THE BRACKETS*** I put it in caps so people would notice this. I'm not mad or anything. It was a hassle to go and order it on amaz*n, and then I had to deal with the horrible UPS service. Just make sure to order the brackets along with the heatsink.

User Review

John C., Newegg
3 February 2011
  • Pros: I was worried that these wouldn't fit in the ASUS Z8N-D6 dual Xeon board, since it was standard ATX, but they fit fine. Installation was a breeze, no problem at all, easier than other large CPU coolers I've had.
  • Cons: In the ATX board I have, it would not be possible to put two fans on both of the heatsinks, you could put two fans on one of them, but not both, that's not really Noctua's fault, but just in case you are wondering.
