High temps for 3570k? Do i need to reapply thermal paste or heatsink?

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?
 
Solution
Your temps sound fine for the stock Intel cooler. If you pull the CPU cooler you need to clean off the paste and reapply. The paste doesn't bond to the CPU its just it will be uneven when you pull the cooler off so you need to reapply.

Ive recently had my computer running and ive only had it about 1-2 weeks, when i play games like chivalry, the temps seem really quite high. They tend to reach 72-75 degrees which i think is quite hot and even when idle they tend to hover around 45-50. Im using speedfan to measure temps btw. Sorry to ask more questions but its kind of making me concerned.

Both Ivy and Haswell run hot. The stock HSF is the bare minimum and it will hit 70C at load unless you have really low ambient temps.

Any after market HSF $20-$30 will knock 10C off that and make for a more stable system. I was getting crashes with the stock HSF. The thermal pad they ship with it is junk.
