Aio temps not stable

[Sgtkeebler]

Hello,

 

When I installed my brand new build, with a Corsair Aio cooler the Hydro Series H60. I have noticed that my temps bounce from 30c to 40, 50 back down to 30c. I used the stock thermal paste that came with the cooler, but what else could cause temps to bounce around like that, and what can I do to fix this?

If 30 is idle and 50 is under load that seems normal to me
