Those temperatures are very low, especially considering that it is in prime 95 and it is maxing out the CPU, but it depends on how much wattage of a PSU you have and how stable your motherboard is, if it even supports overclocking for that matter. If you do not already know how to overclock you will need to go into your bios and each motherboard will be different.
Do you know what motherboard you have and what PSU you have because I can look up if you motherboard is compatible with overclocking and if you will have enough wattage to be able to do so.
Hope this helps and if you ever need me then don't feel shy to let me help, I won't bite! (much)
Thanks,
