Hello, I had my pc for about 2 months, and my AMD FX-6300 3.5ghz ran fine at below 20C on idle with the fan usually running at around 1200rpm. The past few days have been hot in my area, about 90+F. After these two days, the Hyper 212 EVO fan started running at around 1600rmp at idle, and the temperature increased to 28-31C. What's the best way I can solve this issue? Should I clean off and reapply thermal paste, reseat the cooler, or dust off the cooler and the fan? I've enabled smart fan control on my motherboard, and the cooler fan is connected to the 4-pin header. I went into my bios and checked all of my settings, fan control is on and the CPU now runs at about 33-36C when the fan is running at 1300rpm. I've also double checked that my bios was the most current version. When I get into windows, it ramps up to about 1500-1600rpm. I don't know what could have caused this sudden change in cooling performance, and if there are any suggestions please let me know right away.
