I had some money to spend at amazon (gift certificate), so I got a new heatsink

There were cooler models, but the layout of my mobo doesn't give too much space for a big heatsink. This one is supposed to be small. I just got tired of my pc sounding like an industrial vacuum machine.

So, was it a good buy? it seems Zalman has some cool heatsinks.

Do you guys spend a lot of money to cool your machines?
