Interesting temp changes

Hi guys, I have had Primochill Vue in my system for about 2 months now.. I flushed it many times then used their sys prep and whatnot. Anywho... It was great, system was at 17C. Nice and cool in my basement. I just moved to a new house and I have the AC in the room at 70 F.. System is reading 26C, when I game it goes to 30C. Granted I know these numbers aren't bad by any means, but I am wondering if maybe the coolant needs to come out and I need to clean the system again.. Thoughts?

Clean inside the block if you think you lost performance, but be careful with rubber ring but it should be easy.
