Considering that the 750 can Turbo pretty high, I don't recommend stock.Get something like this:http://www.newegg.com/Product/Product.aspx?Item=N82E16835103065
The TX3 isn't that good. But the one I linked to is pretty decent for the price. There are better ones out there, but they don't have LGA1156 brackets out yet. (ie Core Contact Freezer).
