Im planning to OC my i7 3770k to 4.5Ghz once my cpu cooler comes in the mail. When i increase the multiplier to 45 and the vcore to 1.20, how will i know if im not giving it enough voltage? Will i get the blue screen of death, even when im slightly under the voltage requirements? Would it boot up anyway, being damaged in the process?

Damage won't occur under 1.3v from this sort of OC unless it MASSIVELY overheats. OCing is a process, not trial and error. Nor is it a good idea to just set voltage and multiplier and go. Besides, 1.2V will not be enough for 4.5GHz.
Here is a guide and a simplified process.

OK there is a guide, its not really for beginners, so it boils down to...
1. Disable all power saving adn turbo boost features and pick a load calibration, 1 being very stiff and one voltage constantly, 2 being a little more relax(easier to achieve stability), i prefer level 2.
2. Set voltage to fixed at first and drop it to 0.9v. (You can do this with stock cooling as it reduces heat generation)
3. Boot into windows and run prime 95 or similar stresstest to test for stability for atleast half an hour. This will give you an idea of how sensitive your specific CPU is to voltage change. (You can do this with stock cooling as it reduces heat generation)
4. Increase your voltage to 1.2v and multiplyer to 4.2GHz. Test thoroughly for an hour. Keep a close eye on temps with real temp or HWmonitor.
After that you can increase Multiplier one at a time testing for half an hour between each bump. When stability is lost, add 0.05v and try again.
Repeat process until you reach your desired OC or unacceptable temps(drop one clock and/or Voltage) and viola you have your OC...
DO NOT EXCEED 1.3V! Also keep temps under 90C under max load. Although if it touches over it its still fine. It will shut of automatically if it gets TOO hot(103C).
EDIT : Let me just clarify my damage comment. OCing is always risky but you are more likely to burn a motherboard than the CPU these days if you remain in CPU voltage spec.
