Performing CMOS Reset w/ CPU Still Attached

I am currently in the process of troubleshooting my first build. I am attempting to reset my mainboard's CMOS according to its manufacturer's instructions. The instructions say I need to remove all of its components first. This includes the CPU. The problem is that my CPU cooler is stuck really tightly and its removal would prove highly problematic. Also I would have to purchase new thermal paste in order to reattach it afterwards, if I got the thing working. Could I instead skip this process and perform the CMOS reset with the processor still intact? Would it potentially be dangerous, would it stop the reset from working, or is it just a needless formality that can be dispensed with at no cost?
 
Solution
Remove battery, count to 10. Clears cmos.
With pc off, move jumper from pins 1+2 to 2+3, count to 5, move jumper back to pins 1+2. Clears cmos.
Push button on the outside rear of the mobo. Clears cmos.
Push button on mobo. Clears cmos.

There's several ways to clear the cmos, you absolutely do not need to remove anything. Bios is what starts, organizes, hunts the components of the pc, cmos is the list of settings and components bios uses. It's stored on a really small chip. Clearing the cmos just forces the bios to do a full workup of what exactly is in your pc according to factory set defaults. The only component you might have to remove would usually be the gpu, if you opt for the battery removal as many times the gpu is covering...

it will be fine. unplug the psu from the power cord, press the power button to discharge any power left in the psu then switch the power selector to off. remove the cmos battery and reset the cmos according to your motherboards instructions. some have pins that need to be connected by a metal contact (sometimes an included tab or screwdriver) or have a reset cmos button
