I have an old i7 920, paired with a Asus mobo, 16gb ddr3 1600 ram, and an RX570, for a decent e-sports and web browsing pc. I've been looking into higher performance games, like Star Wars Jedi: Fallen Order, and while the RX570 seems to be capable, my i7 920 is going to severely bottleneck the system. So I've been looking into overclocking. I got to 3.2ghz (~3.4ghz turbo) with the stock coolers, but any more and I get into the 90s while stress testing. I've been looking into budget CPU coolers, and my top picks currently are the CM Hyper 212 Black and beQuiet Pure Rock. I need something that fits in a micro-ATX case and has ram clearance. My budget is $20-$40. Is either of these coolers best, or should I try something else, like a Deep Cool Gammaxx? I mainly care about performance (up to 4GHZ overclocked), not astehtics or volume (although both of those would be nice) My main issue is that most cpu coolers are not LGA1366 compatible, so any help would be useful.
