The NH-U12P bolts down to the mounting bars attached to the back plate on the motherboard. They are spring loaded so you won’t be able to over tighten them. You can just fit a screwdriver between the heat pipe and the fins to firmly bolt on the screws and almost be done with the installation procedure.

Last but not least you will need to attach the fans with the two included clips. It’s a bit of a hassle to get them over the fan and under the sides of the cooler but it will only take a minute or two to get them both installed. Prior to installing the fan you will need to install two rubber strips that will prevent the fan from moving and for some possible vibration, but there’s none with this cooler. As you can see on the above picture it clears just perfectly with the Northbridge. Otherwise you could turn the fan the other way, but this might not be ideal if you have a powersupply mounted on the top.

Performance

I used SiSoftsandra’s built in Burn in tool to stress the system and the idle temperatures were measured during internet browsing and minor computer activity.

• All the temperatures were measured using Speed fan.
• All these temperatures were measured with a room temperature of around 21 degrees Celsius.
• And the results are displayed in Celsius
