The provided fan is annoying, ball bearing noisy but thankfully it's upgradable. However, so are Scythe heatsinks, the Noctua NH-U12 and the CoolerMaster Gemini from off the top of my head. I'm sure there are a few more, and these don't have the same 25mm depth restriction. In addition, for £33 I'd expect an awesome fan to come with it in the first place, and while it is "nine bladed for better performance" perhaps a sleeve bearing would be more appropriate?
