## What it is
smcFanControl is a macOS application that lets users set minimum fan speeds on Intel and Apple Silicon Macs to keep them running cooler. It never allows fan speeds below Apple's defaults to avoid hardware damage.

## Use cases
- make my mac run cooler
- control macbook fan speed
- set minimum fan speed on mac
- reduce mac temperature
- monitor mac fan speed

## When to choose
- your Intel or Apple Silicon Mac runs hot and you want more aggressive cooling
- you want a simple GUI utility with safety limits below Apple defaults

## When to avoid
- you need fine-grained fan curve control or per-sensor automation
- you are on Linux or Windows
