I just ordered the CM 212+ and some Arctic 5. In the mean time, can I still use my computer without damaging it?
You should download a program to monitor CPU temperature from the OS rather than BIOS. On my PC (C2D-E8400), I get 45C from BIOS, 33C idle under Windows, 55C at full-load... BIOS temperature is about half-way between Windows idle and full-load.
What matters is the temperature under your typical load with an OS loaded, not temperature readout in BIOS. At 50C, you are nowhere near Ivy Bridge's 105C thermal limit.
