Hi Theo.
Just some FYI, the coolermaster units are not hard at all to install. I've personally put 2 of these in systems I've built for friends, and I've never had a problem.
They have 4 push pins, line them up with the holes, and push down. It even comes with thermal paste on the HSF itself.
I'm not sure what the Newegg reviews are talking about. If there was a chance that you might break your board upon install, then I highly doubt they'd even release the product.
I just thought I'd add a little more info for ya!
But I have to say, the Arctic Freezer model you linked to looks good as well. I run a Arctic Freezer in my current system, and love it! It keeps the CPU nice and cool, and is near silent also.
