Summary: I can't say it's good nor bad, as I ordered it only to find out it does NOT fit with AMD sockets as stated in description. Nor did it come with any type of attachment for any AMD sockets. Amazon, change this so others don't end up in the same boat as I am in. Was excited to try this out as I've heard good reviews about it.
Summary: Review of Zalman cnps9500AT I was hoping for this cooler to be as good if not better than the CNP9700 version but sadly it falls tragically short for me when paired with the latest 4th gen i7. With such wild fluctuations in temperature and its physical limits of 90mm of heat dissipation, the cooler is clearly starting to show its age.
Summary: Stock Intel fan on Pentium D dual core (2.9Ghz) idled at 55 Celsius Installed this cooler with the supplied thermal paste ZALMAN with Pentium D dual core idles at 28 Celsius Stock fan under load 64 Celsius ZALMAN under load 35 Celsius 27 Celsius change at Idle and 29 Celsius change at load is amazing. Highly recommended!
Summary: I had one of these a year ago. It was installed on a Intel 2500k that was not overclocked. It was in an open case. I had 3 fans running in my computer, the zalman cpu fan, gpu fan, and psu fan. This fan was the noisiest of all three. I'd say it was louder than the psu and gpu combined. The gpu was a radeon 7970 reference card which isn't a super quiet card. If you are fussy about fan noise you will not be happy with this.
Summary: My computer has always been a little noisy, it started getting worse. I cleaned the fan and fins out completely but still it was bothersome loud. Ordered this new fan and it dropped the noise by 10db. (now 41db). You still know its running but a huge improvement over before. I'm not sure how this compares to others but glad I made the swap.
Summary: This was fairly easy to install, mostly because both sides of my tower case come off and there is a cut out in the case for the area under the processor which makes it effortless to install the adaptor for the heatsink. For those that have a lesser case, you will have to remove the motherboard. As for how it performs, it is super quiet. While my idle temps have only dropped a couple degrees, load temps on my overclocked 3570K have dropped 30 degrees Celsius.
Summary: I was a little concerned about this fan after I purchased it, because I have 4 Corsair Vengeance ram sticks that might interfere with it. Thankfully, my fears were for naught, because unlike my old, after market CPU fan cooler, this one wasn't as bulky. You see the ones that have a metal square casing with the fan blowing out the hot air. I used to be a fan (no pun intended!) of those until I saw how useful these open ones are.
