I typically run my games on a laptop with turbo disabled, using Throttlestop to maintain stable CPU temperatures. This keeps things within safe limits—usually not exceeding 82°C. It’s been two years now, but recently it began overheating even when turbo was off. The CPU consistently hit 100°C, while the GPU stayed around 65–75°C. Idle temps shifted significantly: without turbo it dropped to 45–50°C, but with turbo they rose to 62–65°C (sometimes hitting high 90s during idle). When I opened the case, I found no obvious dust buildup, and cleaning didn’t resolve the issue. Interestingly, there were these small openings at the bottom—initially thought to be air vents—but they were covered by a black plastic panel and a reflective metal layer. Even after opening, it made no difference. I tried several fixes: adjusting power settings, undervolting the CPU (can’t go below -10.5mV before instability), closing the bottom vents again, and even using Dell Power Manager. Unfortunately, none helped. The situation has persisted for about four months now. I’ve always experienced overheating and throttling since the purchase, but it’s been manageable by toggling turbo manually. The specs are an I7-1065G7 (base 1.30GHz, boost up to 3.5GHz), 8GB RAM, Nvidia GeForce MX230, 1TB HDD, and the latest drivers. I’m at a loss—this has been going on for quite some time.
