cooling question

So i just got around to testing my new system specs will be below. and my cpu was around 65c with prime95 newest version of it. while gaming i haven't seen it go above 45. Just curious if thats normal for a water cooled system as i'm still fairly new to it. Oh and room temp is around 20c and not overclocked.
