Intense overheating on my CPU

[Rhyano]

I have had my PC for nearly 2 years, and up until the past few months I have had no issues. Recently, my computer has started turning off instantly with no warning while playing games. At first I suspected CPU overheating so I swapped my aftermarket CPU heatsink to the standard one that comes with the Intel i5-4670k and applied more thermal paste. This didn't help the problem at all so I downloaded SpeedFan to monitor the temp of my computer and found out that my CPU is at 128°C which is obviously far too high.

Not sure how i can fix this any help would be much appreciated

I'm not sure it's even possible for a CPU to hit 128°C without causing permanent damage. Your temp sensor might be off.
You may know this already, but from the way you explained your procedure, it isn't clear: more thermal paste is not better. You ought to use as little as possible. You definitely need to clean off all of the old paste before applying any more.

I just tried using another program (OCCT) and my results were different, and under 100% CPU usage the temp reached 74°C which still seems high. I will try cleaning off the old paste and re-applying, anything else that could help?

You have to put the right amount of thermal paste (not too little and not too much) to get the optimum result.

74C whist running a stress test is perfectly fine especially if you.live in a warm place these chips don't themal throttle till 90c and shutdown at 100
80c is what most people recommend for the Max temp

Okay cool, any ideas why my PC shuts down when I play games? (I can play League of Legends without shutdown but Rust shuts down quite quickly)

Sudden shutdowns without bluescreens are often because of power problems either with your home power, your PSU, or your motherboard. It's pretty difficult to test where the problem is without swapping out parts. If you don't have a quality PSU, I would start looking there first.
