Why Does My Laptop Overheat? Causes & Solutions | SmartFix Dubai

Main causes of overheating Dust accumulation Dust accumulates inside the casing, blocking ventilation and impairing heat exchange between components. Poor ventilation Insufficient air circulation inside a laptop or PC case leads to overheating, especially if the device is placed near walls, on a carpet, or on a soft surface. Cooling system malfunction Broken or worn fans, dried-out thermal paste, and incorrectly installed coolers are common causes of overheating. High load on the device Resource-intensive games, graphics editors, or multiple open applications increase the temperature of components. High room temperature In hot climates or unventilated rooms, even working equipment will heat up faster. Poor-quality power supply A small or poorly functioning power supply cannot cope with the load, increasing the heat. How to recognize overheating? Performance drops, the PC “slows down” even when performing simple tasks. Uncharacteristically loud fan noise is audible. Restarts, spontaneous shutdowns, “blue screen.” The device case is noticeably hot to the touch.
