Upon turning computer on the CPU temperature is 40 - 45C. When ever I play garrysmod for even just 10 minutes my cpu elevates to 70C. Which is way to high, 3 degrees a minute. After 70 it bogs down performance. I tried the following.
Checking dust and removing with compressed air.
Went into bios and made it so cpu fan is always at full speed.
Clean off current thermal paste, and adding new.
Under clocking. Lowering multiplier and voltages.
Also air circulation should be good.

None of these worked even a bit.

At one point in modern warfare 2 my cpu reached a whopping 85C without stutter. I know this because I set the bios to make a beeping noise when ever cpu reached a temperature. 90C is the point amd says the cpu will likely get killed.

How many fans have your case?

What temperatures do you get on stock speeds? load and idle?
To measure load, run prime95 to make the CPU reach its maximum heat (don't let it go over 60C though).

And yes, what is your case and case fan situation like?

Like i see, the problem is your case. You have a micro-atx case with a 5770 inside and the heatsink of the processor. For the 5770 you need a mid-tower case or something better.

There is a good chance the CPU's Thermal Sensor is not calibrated correctly or defective. When you open the case does it feel like the CPU is omitting 70 degrees heat? If it bothers you, RMA the CPU.
