Is it safe to turn on PC without CPU cooling?

Hi,
I wonder if it is safe to turn on PC in order to get into BIOS without a CPU cooler.
Will it overheat and if it will, will it shut down automatically?
Thanks

No, its not safe to turn on your PC without a CPU cooler, it can get damaged at high temp but it will turn off the computer before that happens which won't be long.

I asked this because i have to attach the CPU cooler now just for checking the PCIE slot (Tried to fixed it after it didn't work...)
Can i attach the cooler without thermal paste?

No, not safe without thermal paste either.

Thank you

The reason why you do not want to turn on a PC without a heatsink attached to the CPU is because prior to entering Windows, the CPU will be running at full speed. SpeedStep is loaded with Windows to slow down the CPU when it is not being stressed.

Thermal paste is necessary because it fills in those microscopic surface imperfection on the CPU and heatsink which can mean a 20C - 25C difference in temperature.

i thought i could be away without a heatsink to see if my q6600 would post. oh it posted and then turned into a $220 paperweight.
