New build heat problems

[ctrl-alt-elite]

Hi all

I finished my new set up last Friday everything works fine the temps at the times where very good was sitting about 40 idle. on Sunday I started to notice a huge change in temp its now sitting about 52 idle and running games anything from 58-70

Any ideas to the huge change in temps?
