Can core temps prevent AMD's Turbo Boost from activating?

I'm currently using an AMD FX-6300 3.5GHz that is supposed to have a maximum Turbo Boost of 4.1GHz but I'm concerned that high core temps may be preventing the boost from activating, further bottlenecking my GPU.

To be clear, I am still using the stock fan and hope to replace it with a Hyper 212 Evo as even when idling, my processor temperature hovers between 40-55 Celsius (room temp isn't the culprit). When under full load, such as playing PUBG, the CPU is frequently hovering around 70. Obviously, this is an issue.

PUBG is a demanding game and I'm not expecting 100+ frames on Ultra settings. I average 30-50 on Very Low despite others with the same specs getting much better performance. I believe this to be because my processor is either throttling or simply never boosting, thus bottlenecking the GTX 950 even further. I haven't run any tests because I'm not well-versed in that category but will accept advice where it's given.

That said, my question still remains: can core temperatures prevent the processor from reaching turbo clock speeds, thereby limiting frames even further?
