Hi Guys, I'm using an old Coolermaster cm690 case with a 980TI gaming at 4k/2k. I seem to be having a problem keeping the temperature down inside the case. The metal case around the graphics card is usually warm to hot to touch after about 30 minutes of gaming. I'm using a coolmaster COOLERMASTER Hyper 212 X heatsink on a kaby lake 7600k. I have 2 main questions and I'm open for recommendations; Is water cooling for cpu worth paying extra? does the case make much of a difference to temperature?
