Hi, I'm wanting to upgrade my heatsink, but I'm not sure what I need. My motherboard is this model: http://www.newegg.com/Product/Product.aspx?Item=N82E16813138373. I've determined I have a AM3+ type socket, but I don't really understand what that means or what it has to do with a heatsink. The stock heatsink the computer came with has a 70mm fan on it. I think this is the fan/heatsink that it came with: http://www.newegg.com/Product/Product.aspx?Item=N82E16835103188. There is about 1cm of space on each side before I would run into other stuff, does that mean I can get a 90mm heatsink/fan and it'll be okay? The motherboard has this like, seating or something for the heatsink and I'm not sure I can remove it, and if I could, what could I replace it with? Thanks in advance.
