I have an HP with a six core 125 Watt Phenom II 1045. I was looking for a cheap small fan/heatsink that will work with an AM3 socket and have the ability to cool a 125 Watt CPU. The case is a standard mini OEM mini tower so big fan/heatsinks won't fit. So the fan/heatsink has to be smal (maybe similar to the stock OEM's and this isn't for gaming just general use so there is no need to pay 50+ dollars on a heatsink.

is the mount for the heatsink like aftermarket mobo's mounts? if so the any low profile heatsink like thermaltake would work. if it is a proprietary mount then it wont be that simple.
have you looked into just changing the small fan with a larger one?
Although it IS quite a bit more expensive than the ones you linked (still only $34.99). My one worry with the one I linked would be mounting, but as long as the mounting holes are there, I don't see why it wouldn't work.
Thats nice but seems kind of like overkill for just web browsing, MS Office and youtube video's.
Oh, no doubt. It absolutely IS overkill for that, but there's no harm in keeping it cooler than a stock-type cooler can.
