Nice bit of kit this. My Northbridge chipset fan was noisy when new but my PC is now 3 years old and the fan sounds like soneone drilling. The installation does require you to extract the motherboard to pinch out the existing pins which attach the Northbridge fan but once these are out it's pretty simple to line up and attach the brackets and pins for the new cooler. It comes with thermal paste but you'll need to clean up the old paste on the Northbridge first. Methanol is a great solvent for this. Positioning the cooler can be a bit tricky if you already have a large cooling fan for you CPU but the asymmetric vane arrangement and adjustable brackets permit you to twist the cooler round to fit it in snug against the CPU cooler vanes. Just remember to earth yourself to avoid zapping ESD sensitive chips in your PC.
I installed the Zalman cooler as a replacement for the noisy fan on my MSI K8N-Neo4. Removing existing fan and installing the cooler was easier than I expected, once I had followed the instructions. Excellent results so far, my PC which I use to support musical activities (keyboard, midi and video play) is now acceptably closer to the silent background I aim for,
I found it very simple to fit and certainly beats a noisy fan option and does the job quite satisfactory. You will find though its a lot easier to do with the motherboard out of the case unless you have really small hands.
