I have an aerocool cruisestar advance pc case with an fx-8300 with a TX3 evo cooler and an asus r9 290 directcu II oc. So the problem is that I have around 70°c on the CPU with stress test, and my videocard is at 50-55°c in idle, 60-63°c when I watch online videos or streams and running older (2013) games it easily reach 80-90°c. The card was bought 4 years ago and it has it's stock thermal paste. Neither of them are overclocked. Someone told me to move my build to a bigger case and to repaste it. It would help? The Cooler Master H500 (mesh) is only 75$ in my country. It would be a good improvement? And if I have to repaste it what thermal paste do you recommend? And my cpu's temperature would be better with a CM ML240L liquid cooler?
