Temperature update. Running AIDA64 for about 20 minutes gets the water temp up to 28 degrees and seems to stay there with my fans at about 850rpm. Intake air temp was 23 degrees. My CPU is at 4.7ghz with 1.295V. Temps are between 50s and 60s, with max temps spiking up to the low 70s. I'm not sure if that's normal under stress testing. I'm going to go ahead and repaste and reseat the CPU block to be sure.
Looping Unigine Heaven gets the GPU up to 40 degrees.
