High temperatures on the CPU can harm the motherboard.
High temperatures on the CPU can harm the motherboard.
A high temperature usually means the CPU is getting too hot. The motherboard isn’t likely to be impacted by the CPU’s heat.
Yes, certainly too much heat might harm your board, but most reliable motherboards usually manage it well under normal conditions.
You can achieve maximum performance from your motherboard if your CPU isn’t too demanding. The parts are built to handle extended operation, but how they perform depends on the heat they generate. For instance, a 9900k on an H310 board will function, though the VRM will limit itself (and the CPU) if power demands exceed its cooling capacity. I wouldn’t anticipate the board lasting as long as another with better power delivery.
