Summary: Cools great. Looks great. But I don't know if I got a bad unit or if their fans are just junk. I've had it for about 6 months and most of the time its running at idle speed. The last couple months the grinding noise has been getting worse. I tested all the fans in my case, and manually ran the speed up on each one, and it is this unit that once it hits about 1500rpm the grinding noise goes away.
Summary: I have had this (blue model) on my PC for about two years now. I run an AMDx6 1090T overclocked to 3.7GHz. This idles at 24 degrees C and running Prime95 for hours result in max temps of about 43 degrees. I recently picked one up for an AMD A8 quad core. This is a 100W quad core APU and running Prime95 I could not get the APU to go above 38C. Amazing considering how quiet this is. It's big, gorgeous, and performs like a champ.
Phenomenal performance but extremely difficult to install.

Summary: The Good To put it simply the performance is spectacular. Though there was only a 5-6 degree drop in my idle temperature there was literally a 20+ degree drop in my temp at load. It went from 50-60 degrees to around 40 degrees. The Bad It is extremely difficult to install - frustration incarnate. It took me 6+ hours to install. Other Be careful with the directions. They are not difficult but If you don't follow them closely you can easily make a mistake.
Summary: This Zalman cooler is beautiful. The red led accents the heatsink in a way that it looks like it's glowing. As for performance, I rated it 4 stars because the heatsink is being used with an FX 8350 -which by nature is a warm processor; the heatsink performs well at cooling the CPU, but at a minor overclock 4.3Ghz..makes my idle temps around 40C which is not terrible...but I feel it is a little warm for a higher end heatsink.
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.
Summary: I did my home work and made this choice because of the design. It is fairly quiet. Processor temp remains below 40 °C, here in the desert south west with no air conditioning. The install was a easy twenty minute job. Bigger is better when over clocking.
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.
Works great for cooling, but the design is terrible.

Summary: Ive had mine for about 6 months or so and it cools great, but the fan wobbles now so you always have this little ticking noise whenever the the computer is on. Super annoying. I am switch to another fan.
