Features:
As mentioned before, this cooler is entirely passive, meaning there are no moving parts on it to create noise. Off the base there is a U type heatpipe which stretches up vertically and a stack of 20 round copper fins which are mounted on the U part of the pipes. Nexus chose to make the entire NHP-2200 from copper because as you may or may not know, copper is a very good heat conductor. Due to the design of the NHP-2200 there is no way to mount any kind of add-on fan. Some other manufacturers offer this option for those who prefer top performance over silence.

Something I found very appealing with the NHP-2200 is the fact that it is compatible with all motherboards. I run across so many chipset coolers out there which are only designed with a certain platform in mind, leaving those who don't have that chipset platform unable to run that cooler. Nexus has included a huge range of mounting hardware with the NHP-2200 and with the included mounting brackets that screw on the heatsink itself, they say you should be able to run it on any motherboard!

Installation:
Installation will be different for everyone because depending on what style of mounting your motherboard has for chipset coolers you'll have to use different mounts (all are included).

For me, I was installing it on the Nvidia NForce 4 Ultra chipset on my Biostar NF4UL-A9 motherboard. This motherboard uses the push-through spring clip style of mounting. Once the old cooler was removed, all I had to do was put thermal grease on the bottom of the NHP-2200 and hold the mounting brackets over the motherboard's holes to push the pins through.

(It was a tight squeeze to grab an action shot in my rackmount computer case, but here it is!)

However, I was quick to run into a snag here which required me to do some CPU cooler swapping. Up until I went to install this cooler I had been running a Spire KestrelKing cooler as opposed to the stock AMD cooler. The metal clips that hold the KestrelKing onto the mounting platform have a slight outward arc and a large metal nub at the top to hold onto and push during installing. This metal piece conflicted with the height of the NHP-2200 cooler I was trying to install on my chipset which was very close to the CPU cooler. Since I'm aiming for a silent computer and I don't overclock, I simply put my stock AMD cooler back on because it had a more compact mounting system. This gave me the clearance I needed to properly install the NHP-2200.

Conclusion:
In the end I was extremely happy with the Nexus NHP-2200 northbridge cooler. Being a completely passive and silent cooling solution it got rid of the rather annoying whine of my previous northbridge cooler fan. The design and build quality is also very excellent with this product. Made entirely of copper and heatpipes it is a highly efficient cooler and should leave you with no reason to worry about not having a fan. However, I was a little disappointed that there is no extra way to mount a fan for those doing extreme overclocking who may want to add some extra cooling to the NHP-2200's ability. All in all, this is an excellent product with great design and performance!
