Summary: I won't waste time saying how amazing this thing is, just look at the spec's. Take note my case has many fans in it and is big! Idle times: 18 - 22 Degrees. During Games: 25 - 35 degrees. With my stock cooler I was always 30 or 35+ idle or not. Madness how low this thing keeps the cpu. Zalman's stuff has yet to disappoint me.
Pros: Big! Quiet and cool LED. It definitely looks like its doing its job.
Pros: the zalman is easy to install and comes with attachments for the different size chipsets. once installed i noticed a consiterable change from my old heat sink. it was one of the square ones with a fan. this cooled about 3-5degrees cooler idle and under load. this heat sink gets close to 10 degreese cooler than the factory intel heatsink.
Cons: hard to clean. since all the fins are close and rather sharp you should get a "throw away" tooth brush to use as a duster. it is also because there is not much space to clean between the fan and where the dust builds up.
Pros: Has been cooling a i7 920 for three years now. Nice icy cold temps even with mild overclocking. Has a blue led that is pleasing to look at when i take my case cover off every 6 months or so. Tall enough to not interfere with ram sticks.
Cons: PITA to clean after years of use, but i don't imagine that any air cooler would be easy to clean.
Summary: I actually had to watch a video to get the installation instructions straight in my head. Much more involved than my last cooler, but definitely bound to the CPU for efficient heat transfer. It's quiet, all copper and blue. I have to take a star only because of slightly more involvement of installation.
Summary: This is one of the best. Good finish. Does the job well. Depending on your case( if your CPU underside is exposed) I installed it on an existing system without dismantling.
Pros: Easy to Install on a Intel 1366 board. Good fit and don't look at the size of the box as this will fit in any regular ATX case. Putting the fan in the center makes the size compact. Ideal for Southbridge as they tend to run hot.
Cons: If you don't get cuts with the fin you are lucky. Keep the plastic cover on until you are ready to install. Takes a while to center it on top of the CPU.
Summary: I really like the cooler and it keeps the CPU (i7960) at a good temp. Max temp after hours of gaming so far was 47 C / 116 F. Might get a bit higher in the summer. Large cooler so make sure you know it will fit before purchasing. Fit with a bit of room to spare in my Antec DF-30 case. Happy I went with this one as i did not want to get into liquid cooling.
Pros: good temps, like the look
Cons: not a con for me but it is very big so make sure you have room
