What’s an appropriate operating temperature for a CPU under load? 70C? 75C? How about 95C? That’s what Lenovo apparently thought when designing the T480s. Thermals are important with this build. I didn’t focus too much on it initially, because remember when I opened the Stealth up? It had cooling on lock, even though the fans were noisy. Keep that in mind for later. Let me regale you with my encounter.
