CPU overheating issue, what steps next after dust blasting?

Hello, I have recently been given a PC, it is rather old and has an i5 760 CPU(stock cooler, not overclocked). I have noticed it can reach the mid-high 80Cs when under load though, which has me concerned.
Cleaned out dust from the heatsink with compressed air, cleared dust filters, fans etc. Idles at 35C generally, hits 80's in games(GTA V on low settings for example, I know the CPU is ancient but it does surprisingly well aside from the heat), but rapidly cools down again once I shut them down.


My thoughts are...could thermal paste be an issue? The system must be 6 years old by now, and has never been replaced.

The case is a Cooler Master Elite 430. It has one front intake fan, one rear intake fan, and one upper exhaust. I am clueless when it comes to PC's but I feel like the rear fan being an intake may not be a good thing, so would appreciate some input on what kind of setup may be best.

Or is it likely that thermal paste + fan setup will make very little difference, and I just require a new cpu cooler(a whole new CPU would be nice)? I know it will give results, I'd just like to fix it cheaply with products I already have if possible.
Thanks for reading.

Stock coolers were never that great, but older CPUs like that draw exponentially more power than modern CPUs like the intel kaby lake and ryzen do, therefore they generate way more heat. If you're that worried about it, or if you're running an overclock, I would look into something like the coolermaster hyper 212 evo, or geminii, or if you want to go 100%, your case should support a small radiator on the back panel, and possibly a 240mm radiator on the top ( I didn't measure the top for you, so I'm not 100%).

EDIT: I forgot to mention that not only did they draw more power, but Intel and AMD also accounted for it in a lot of their designs. That processor is pretty well known to get pretty warm, but doesn't have a ton of issue handling...

That processor is pretty well known to get pretty warm, but doesn't have a ton of issue handling temps between 75~78C, but of course running any semiconductor with excess heat for extended periods of time chips away at its lifespan, so if you want it to last you as long as it can last, I would pop in a new heatsink of any sort, for sure. Just make sure whatever cooler you end up with supports your socket type.
