During the hot days, I noticed my PC is getting really hot. NOw, none of the temperatures are dangerous (CPU: 65C MAX; GPU 67, jumps sometimes to 75 MAX), the hardware is raeally old, so I don't want any risks. If the hardware was new, I wouldn't worry. Tthe PC is clean and has good airflow. I will change the thermal paste in a few days. And, since the GPU is getting really hot, I have underclocked it by 20%-30%. My question is, any other sugestions to cool my PC down a liltle, til I fix it?
