I recently bought components for a new computer, put it all together fine and when booting into the bios the temperatures seem to be quite high for the cpu (i5 3570k). They start at around 45 when booting, however after about 10 minutes rise to 55 degrees average. I have tried to see if the stock heatsink is correctly installed and all of the pins have clicked into place and show at the bottom of the motherboard. The only thing i can think of is that when i first put the heatsink onto the cpu, one of the clips didn't click into place, however if i pushed any further it would probably break the motherboard. If i have already had the computer on for about 20 mins max, can the heatsink be taken off and reapplied, or will i have to take off the old thermal paste and reapply some different thermal paste or will the existing not have properly 'bonded' to the cpu yet?
