It's exactly the same one used in the SK-6. Commonly known as the 'OEM' clip, you will need a screw driver to mount this cooler. If you read my earlier reviews, you should know that I dislike this mounting method. I actually prefer the Global WIN clip. It's safer, easier to install and provides more than sufficient mounting pressure.

This clip uses only one hook on each side of the socket, thus making it Socket 370 friendly. Most flat-head screwdrivers will fit into the 'pocket'. You can reduce the chances of slipping off the clip by using a bigger screwdriver.

The Fan

They sent me a different fan, not the Sunon fan as stated in the specification sheet. It's actually a sample model called Motor-One. I don't know the actual rating of this fan but it is 60x10mm in size and spins at around 4500 RPM. I would be surprised if it actually blows more than 15 CFM of air.

This is considerably less powerful than higher-end 60x25mm or even 60x38mm fans, up to three times less. Anyway, it's not supposed to blow a lot of air since the cooler was designed with emphasis on a low-profile and with a low-noise fan.

This fan can be classified as quiet by today's standard. I will always remember when the YS Tech 26 CFM was considered as a noisy fan just a few years back. It comes with a 3-pin connecter and unlike Delta fan, it draws less current. So, it's safe to plug this fan to the motherboard's fan header.

As you can see from the picture above, the last three fins on each side are slightly raised, just like in many other heat sinks. I'm not an expert in this field but according to various sources, this reduces the fan's dead zone and reduces the noise level as well. Correct me if I'm wrong! :)
