How to keep CPU a little cooler?

I’m using a 7800x3d with a Kraken Elite 240 set to exhaust out the top, in CAM the pump and fans are both set to performance mode, it’s not OC’d or anything, I just want to figure out how to cool it down by 5 or more degrees. It gets to 78 sometimes but never touches 80, I know that’s not a big worry but I know I can optimize it a little more. I’d appreciate any tips!
