Would a stock Intel HSF be sufficient to cool an i7-4790k for gaming, or should I get something a little more capable? The stock HSF I have now keeps my 4770 under 88C during Prime95 torture test, and below 80C normal gaming. Alternatively, I was thinking something like this. Clearance is a concern in my Optiplex 9020mt case. This is what I'm working with. I can get dimensions later if anything more specific is needed. Budget for the CPU cooler should be less than $75CAD. Thanks.
