So I built a PC and decided to use the stock Intel heatsink (since I don't over clock). While cooling-wise it's fine, the thing is a jumbo jet. I can't stand it. I'm looking to replace it, but I noticed my motherboad (ASRock Extreme 4) doesn't really offer a lot of space. Does anyone know of a good, cheap cooler that would fit in on that board? The stock cooler is pretty much taking up all the available space so it pretty much can't be bigger than that.
