I was thinking about overclocking my Core i5 760 to see if I could get a little more juice out of this old war horse.
I downloaded the Intel Extreme Tuning app and ran a CPU stress test. my processor imminently jumped off the charts to above 99C!
So i opened it up, took of old thermal paste, applied new coat and ran the test again, the CPU now idles at 45C, but it will get up to around 90C running the stress test. Is this too high?
I have come to the realization that overclocking this chip with the factory fan/heatsink would be Ill advised. But are these temps with the factory clocks still to high?

I do not think your experience is out of line.
Older chips do run hot, but at about 100c. or so they will throttle to protect themselves from damage.
Idle temps should be 15-20c. over ambient.
The stock cooler is not very effective for overclocking, and it is tricky to install.
A "new coat" of paste sounds to me like you have used too much, and it is acting as an insulator. A drop would be a more apt description.
Make certain that all 4 pushpins are through the motherboard and locked. There should be no wiggle/
I might suggest you buy a $30 cm hyper212 or similar, regardless. It will be quieter, run cooler, and will be transferrable to a future build.

thanks for the response. I make a very thin "S" with the thermal paste with my finger then spread it smooth with my finger. is this too much?

Yes, likely too much. Just a small drop will spread out under heat and pressure, leaving no air pockets.
Everybody has a different method.
The arctic silver web site has a video tutorial.
