So I have an i5 4690k overclocked with a hyper 212 cooler, R9 390, and a Fractal Define R4 case with two 120 mm intake/exhaust fans. The air around my PC is just getting way too hot for my comfort. I am pretty sensitive to heat and sweat A LOT on summer days or when working out, so when I am playing a very system demanding game that gets my GPU temps into the 70C range, I start to feel the intense heat around my face, and it makes me start sweating bullets. The problem is not the room temperature but just the intensity of the heat coming from the PC. I have the door wide open and the thermostat in the room will be at 65 F, but I'm still getting too hot. I think the problem is that the exhaust fan on the R4 is not pushing enough of the hot air out the back, and too much of it is coming out the side by me. I need something that will dilute the air coming out. I thought about installing a side fan to blow om the GPU but the R4 only supports 140mm fans. Do you think I should get a case that supports bigger fans like the 200mm that comes with the Carbide 500R? Would a water cooler for the CPU help?
