Excerpt: Great techie look and excellent cooling without the noise! OK, so the techie look is not the most important part of a CPU cooler. What you really need is the most cooling for your money and you don't want a lot of extra noise. This cooler has a single variable speed fan and the cooling tubes (heat transfer tubes) wrap around the fan.
Summary: Installed on top of i7-4790k 4ghz chip. MB asus sabertooth z97. Fits fine. Cools well but im not overclocking. Install video on zalman website more useful than whats in box. Shape and size makes it awkward but not hard to install and you wont cut your hands like others say. However you can bend the fins if you mishandle. Overall very happy with it. Somewhat quiet.
it runs super quiet. On the second build (i5-4690K) I Installed ...

Summary: Second purchase for a second build. I did not try to compare this fan to the stock Intel fan on the first build because I wasn't taking any chances; it was the first choice. Atop a i7-4790K, it runs super quiet. On the second build (i5-4690K) I Installed the stock fan just to see... I saw 44C and which dropped to 33-34C once this fan was installed. If you're not going hydro, copper rules and the price point is a bargain.
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.
