Sony Vegas Rendering is causing temp to go high... Help

[BurntheHeights]

I have been running games fine, idle temp is around 25-30c but when I render it's reaching 70c -75c

My motherboard beeps when get it gets hot. It's quite annoying... What the fuck is going on?
I reset the cpu and tightened the h110i, I noticed a few bent pins on the motherboard, I bent them back carefully and everything works fine. Rendering just kills the temp

Rendering puts 100% pressure on your CPU, most of games don't since they are GPU intensive. Your Heatsink + Fan sounds to be too weak to handle with the temperature of your CPU or thermal paste has tried out.

Either replace Heatsink with a more powerful one, re-apply the thermal paste or UnderClock your CPU which means force your CPU to work at less maximum power than it actually can. So for example instead of letting CPU work at 3.5 Ghz downgrade limit to 3.0 Ghz, doing so will reduce the temperature but so will the performance. Clocking settings can be accessed in BIOS and/or sometimes in Motherboard Utilities.
