Great cooling, not so great instalation on an AMD board
26 March 2014
Summary: I love Zalman products, great cooling, really quiet. I installed this on a AMD AM3+ motherboard. Like others said, the screws are too short, so be prepared to go to Home Depot (bending and pushing will not work, you will damage the motherboard). Otherwise I use this to cool an FX-8350 overclocked to 4.4 Ghz, and the CPU at full load reaches 49 C only with the fan spinning at about 1300 rpm. I give it a 4 out of 5 just because of the installation.
Summary: This is hard to install as AM3+ the screws to attach the heatsink are to short if you want it to work you have to first put the first screw in while placing the heatsink at an angle then place flat pushing hard and constant pressure place the other screw in only put the screws in a few threads enoff that the screws will not strip out these screws will strip out very easy on the threds and even more so at the head use extreme caution when tightening the alen head will...
This thing is phenomenal at cooling, but is a major head ache to install

Summary: My i7 4770k is humming away at 25c with this thing spinning on top of it. I'm really happy with it now. Conversely, I was so irritated I almost threw it out the window while I was installing it. It literally took me two hours to install; it took me more time to install this than to put together every other piece of my PC combined. It would make things easier to just completely take your motherboard out when you install this. Lining up the pins with the screw holes...
Summary: I bought this cooler a few months ago and it performed flawlessly when I was using it. Installation (for an intel cpu atleast) is fairly straight forward. I had it on my 4670k which is overclocked to 4.7ghz. Idle temp is ~30-33C, and at full load with something like prime 95 temps never went above 70C. I bought this before I decided to go with a red/white/black color theme, so the blue led obviously didn't match (yes I am a bit crazy).
Summary: Pros: Quiet, pretty blue LED, Looks impressive in your rig (if you have a window to the mother board). The temps are doable, seem to be cooling the system enough under stress w/o any abrupt shut downs. It's not obstructive on a ASUS Z87 Pro motherboard for RAM. (a big problem with aftermarket CPU coolers) Cons: Dear god Zalman put out a new backplate adapter for the 1150 boards. This one was a pain to put on. I got it on, but wasn't happy the time and cussing it took me.
Looks and works well, but don't discount the size of the thing

Summary: After measuring a couple times I knew this thing would fit and it did, but this thing is huge. I'm using this on an Asus z87 pro with a new 1150 socket intel. Des not impact memory slots. Make sure your case is large enough.
Summary: I've built several rigs for myself and others, and this was one of the more difficult heat sinks that I've ever had to install. First, you really don't want to consider this if you have anything below a large case. Medium cases can fit it, but they will be tight and there could be any number of things that might prohibit proper installation. At any rate, I followed the installation guide to the letter. I found it to be mostly clear and easy to understand.
Summary: Pros: -Does an excellent job at cooling. Dropped around 15-20c from the stock cooler on my i7-2600k -Is relatively quiet, I can't notice it over my other case fans. Cons: -Was a pain in the $%# to install. I nearly bent both my motherboard and the fins on this thing trying to get it screwed down. I had to get a second person to hold the thing down while I screwed it in.
