Summary: I'd say after I installed this my cpu temp dropped almost 20 degrees. Staying in the 30s with light activity as before it was in the low 50s. Just know the install requires a plate to be installed with screws in the back of the mother board. I had read the reviews so expected it. Pretty easy install, it is very large though but I have a normal size case. If you have a tiny case may look for something else. Oh and the fan is pretty quiet.
Summary: This was great for my computer. I was concious about the amount of space I could take with a fan, and this fit nicely. It also gets the job done. It has a great amount of air-flow for the fan size, and it is entirely silent. Great product!
Summary: Zalmans with the heat pipes,and fans with this configuration have always workrd well..this one is of no exception..A little smaller then then the 9700 abd 9900,this works great for some HTPC builds.. I used in a a couple Silverstone builds..perfect height,quiet,pwm..does the job..Zalmans for me have always worked beyond the expected and useful life of the builds they were in..
Summary: This is a fantastic unit and a quality product. I originally went with a Cool Master GeminII M4, but was very disappointed with the fit (blocks DIMM slots) and manufacture. For less than $5.00 more I picked up the Zalman based on their reputation and other user reviews. I couldn't be happier, this is a fantastic piece of hardware. Not only does it look cool (no pun intended), but it works great. My CPU temp would occasionally hit 80C after a round of heavy gaming.
Summary: I just built my husband a new computer, had a moment of concern when I didn't see LGA 1150 listed on the box for compatibility, but it fit and worked just fine. It's keeping his i7-4771 nice and cool. This one does NOT have LED's but on the bright side, unlike the version of this cooler that is similar but does have the blue LEDs, this one is PWM controlled. I like that. And since this build has green lighting I didn't really want blue LEDs anyways.
