Coolermaster makes some heatsinks that were designed for prescotts. I have one for my e4300 it moves 80cu feet of air with a 95mm fan and is pretty quiet at full speed, and while made of aluminium it has a copper insert that makes contact with the CPU. It runs $10-16 shipped in the US, and is available through European sites as well. http://www.coolermaster-usa.com/Products.aspx?pid=1258
