Temp Issues in 200R

[Spencer_4]

I just built my PC (specs listed below) and I am having some higher than expected temps while playing some games. I have been hitting up to 78 C on my GPU and 53 C on my CPU (not overclocked). I wanted to start overclocking soon but not sure if i should be worried about these temps as a starting point. I installed 3 extra fans to case, a second 120mm intake in the front, 140 mm intake in bottom and 140mm at top for exhaust. Any suggestions on how to run cooler and/or if its a bad idea to over clock at this point?

I would take the bottom 140 and put it the top. I have a very similar setup and I use two intakes at the front, two exhaust in the top and the rear is an exhaust. Orient the CPU cooler and fan so that it blows through the cooler towards the rear fan. My motherboard temps stay at nearly ambient temperature all the time.

I am not sure that switching one fan in the case is going to give me a substantial cooling advantage

It's all about airflow, not necessarily how many fans you have, You pull cool air in from the front, and it travels up and across the motherboard, picks up heat, then exhausts out the top and rear. Cables in the way, or a fan blowing the wrong way can disrupt that smooth flow of air.
