You can pick one up from almost anywhere for fifteen pounds or less. I have attached a fan speed controller (about 3-4 quid, you can even make your own if you are technically minded), and my computer is now almost silent, whilst still a good twenty degrees cooler than the stock AMD cooler. The fan itself also has no problem with fitting any AMD CPU socket (They do a pentium model too), and at full speed its still less intrusive than the stock.
Its the best purchase you can get by far, without spending fifty quid plus, and even superior to some of those. I recommend it wholeheartedly.
