Cooler looks adequate but at the high reaches of an fx overclock, it still may not stay under a preferred 55c on core and package temps. I don't exceed 55c on my overclock in stress testing.
here's an example of my
current bench on userbenchmark.com
and
cpu-z bench
Hope it's not too much info but the point of that is to show that you get something but not much from the overclock. It's better than the default boost of 200mhz on 1 core, in my example it's 4.4ghz on all cores, and not much point in going any higher, I could get it to score 272 single threaded at 4.7ghz, but it doesn't have much real world impact on any games in my inventory. 20 points on the benchmark over default clock is nothing for a cpu, totally insignificant.
I think the cpu-z bench would be about 295 at 5ghz, which is still far behind many intel quad cores & way behind ryzen. Also the scores for the other cpu's do not include their overclocked bench, only their default, so the fx 8350 is about halfway in the list, not the worst performer but far from the best, and given it's increased power consumption and temperature overclocked, and nearly insignificant impact on gaming frame rates, it's hardly worth the additional stress/temperature/load/risk.
psu tier list <- hope your unit is on it!
I can provide a benchmark of a non operational system as well. 0.
