Where are the fan vents on a MacBook Air?
MacBook Air computers have vents along the back near the clutch. The surface your device rests on can block its vents, affecting fan behavior. If you use your device on a soft surface like a couch, pillow, bed, or your lap, its fans might run more. Using your device on a hard, flat surface like a table or desk is best for temperature control.
When fans speed up, use Activity Monitor to look at CPU usage and note “mds” and “mdworker” processes with high utilization. When indexing completes these will settle down and system will cool. Spotlight indexing alone is a high load and causes racing fans. Other CPU intensive activities running at same time add to the load.
Why is my MacBook Pro overheating after a new SSD?
You will find that users of older Macs tend to have accumulated more data so indexing has much more work to do than on a fresh OS i stall, and that when migrating after a fresh install, indexing is gated by migration speed.

Where is the fan on a MacBook Pro 16 inch?
The min is 1836 on one and the other is 1700. You’d think Apple would put in identical fans. Right above the touchbar my maxed out 16″ MBP gets super high. So hot it can burn your fingers. Even the touchbar itself gets hot. What is strange is the machine runs hot when it’s only running Safari.
Is the fan noise on a MacBook Air annoying?
We are testing two new 16-inch MacBook’s before doing a rollout across our organization. Under low loads (25% cpu utilization), fan noise will get annoyingly loud.
