Depending on your ambient, those gpu temps aren't that great, either. I know you have an XSPC bay res on the bottom of your case, is it using the XSPC 750 pump? It would be inadequate for your loop to hit the standard one gallon a minute threashold. Your loop has a pressure drop of aroun 4.1 psi, and the 750 pump is only rated at 3.59. Check this out:

With temps of 67 on the CPU I'd reseat the block anyhow, just to be sure. You'll hear it a bunch if you stick around, so I don't mind being one of the first to tell you to ditch the dyed coolant, too
