Summary: I would not buy this cooler again unless I had space concerns in my computer case since it is has been made obsolete by newer designs; however this is very well made. The heat sink is solid copper with a base polished to a high mirror finish.
Pros: Very high build quality, low noise, great cooling, long life, super easy install on amd platforms (its just a simple spring clip)
Cons: Out performed by some of Zalman's newer designs
Summary: I chose this version because my rig is black with green lighting and the only lighted fan option is blue. This is not a big deal at all for me as performance of the cooling far outweighs and aesthetics.
Pros: Very efficient. Nice and quiet. Installation was quick and easy. Unique aesthetic looks.
Cons: You have to be careful when handling it on installation. I bent one of the fins ever so slightly and while no one else will see it, I know it's there.
Summary: Zalman CNPS9500. I installed this huge monster on a heavily used E3 Xeon server with a raid controller, expander and 10 hard drives. On the old Zalman about 15% the size you could just hear this server located in the corner of my room if you focused on listening for its sound.
Summary: I have my motherboard setup to do CPU smart fan control so the fan doesn't go more than 1500 RPM and is super quiet. Stock E8500 @ 3.16 and idle temps are 30C in a 76F room! Prime95 small FFTs doesn't take it above 55-56C while still maintaining 1500 RPM! Arctic Silver 5 for the thermal paste.
Pros: Copper, Easy to install, Super quiet at low rpms
Summary: I just installed this in my Dell Inspiron Desktop with a Q6600 2.4Ghz overclocked to 3Ghz. Wow, it's running at 10C cooler and the fan bolted right into the mainboard with no need to remove it! So far so good! The Tuiniq TX-2 and Arctic Clean were used for the install and I'm happy with the results.
Summary: I have a Intel Core i5 4670K @ 3.40GHz on a SABERTOOTH Z87 (SOCKET 1150) motherboard. I was already switching cases so I figured I'd get a new CPU fan to help with the cooling. The install wasn't bad at all apart from the blood sacrifice.
Pros: Very effective cooler that doesn't weigh much more than an Intel retail cooler. It doesn't require a plate on the back of the motgerboard, just 4 nuts to secure the mounting frame. Because of the way the frame is designed, you can orient the cooler 4 different ways to direct the airflow as you wi...
Cons: Large physical size makes it challenging to mount the cooler while the motherboard is installed in a case.

Summary: I purchased this for my Z97 Nightblade case (which is very small but fits full size graphics card) and it fit perfectly. I had to take my graphics card to get one of the screws into the base however it works. My temperatures went from being 43 degrees Celsius idle to being 28 degrees Celsius idle.
