That seems kinda hit or miss. I'd rather just get a new one to be honest, the 1050 ti has arrived just in time, although I would prefer the 1060. I'll just stick with my integrated gpu for now I suppose. I was able to run BF1 on it before, albeit at the lowest resolution I've ever played a game at but it ran at 60fps.

That kind of overheating isn't something that can really be called even overheating. Its more likely that some background process started and required that tad much more CPU power that fan needed to boost its rpm. However you should consider continuous temp monitoring. RealTemp is good for that as you can use its task bar icons to check temps while on desktop. If ramping happens again, check highest temp that cores have reached. If thats over 85C then we can talk about overheating.

Like everyone said applying new thermal paste would be good; it's something you should try to do every once in a while.

Check your temps with RealTempGT.

Try removing the cooler, cleaning off the thermal paste, cleaning out the fins of the cooler, applying new thermal paste, and putting the cooler back on.
 
Might as well clean out the rest of the dust while you're at it.
 
 
From what I have seen, after a few years of use most computers need the thermal paste replaced as it tends to be pretty cheap shitty stuff that dries up over time and becomes useless, though that typically is with pre-built systems.

You might need to change the thermal paste.  And reseat it and that will be that and it will probably run more cooler.

When was the last time you cleaned out the dust from your PC and replaced the CPU thermal paste?
