can you please keep the programmes running for 15mins and use them whilst checking the temp just to check.
I'm sorry, but this is total nonsense.
CPU and GPU heat up in a matter of seconds and they either overheat, or not.
Temperatures will raise, if some heavy programs are used, not from waiting.
Computer is not like a bonefire, which needs 15 minutes to heat up.
In either case, temperatures won't raise from 54 to 100, even if you wait until tomorrow.
