MacoolerMac Fan Control: How to Control Your MacBook's Fan Speed
By default macOS keeps your fans quiet until your Mac is already hot — great for silence, not so great for performance. Taking manual control lets you spin the fans up before your Mac starts to throttle, so it stays cool and fast under load. Here's how, safely.

Why control your fans at all?
macOS runs a conservative fan curve. It prioritises silence, so it lets the chip heat up and only ramps the fans when the temperature is already high. That's fine for browsing — but if you export video, compile code, render 3D or play games, your Mac can reach its throttle point and slow down while the fans are still spinning gently.
Manual fan control flips that trade-off. You spin the fans up earlier, the chip stays further from its thermal limit, and it holds full performance for longer. When you're done, you hand control back to macOS and the fans go quiet again.
Which Macs have controllable fans
Fan control only exists on Macs that physically have fans. Quick reference:
| Mac | Fans? | Controllable |
|---|---|---|
| MacBook Pro 14" / 16" | Yes (two fans) | ✅ Yes |
| MacBook Air (all models) | No — fanless | ❌ Nothing to control |
| iMac | Yes | ✅ Yes |
| Mac mini | Yes | ✅ Yes |
| Mac Studio / Mac Pro | Yes | ✅ Yes |
MacBook Air ownersThe Air has no fan — it cools through its aluminium body. There's genuinely no fan to speed up. If your Air runs hot, see the overheating fix guide instead.
How to control your Mac's fan speed
macOS gives you no built-in fan controls, so you need a small native app that talks to the Mac's system management controller (SMC). The steps are the same on Apple Silicon and Intel:
- Install a fan-control app. Macooler is free, native and notarized; Macs Fan Control and TG Pro are alternatives.
- Open it and find your fans. You'll see each fan's current RPM and your live CPU/GPU temperature next to it.
- Raise the speed. Set a higher fixed RPM, or a custom curve that ramps the fans up sooner as the temperature climbs.
- Watch the temperature drop. Within a minute or two the temperature falls and your Mac holds its performance under load.
- Hand control back. When you're finished, switch back to automatic and macOS takes over again.
Take control of your Mac's fans
Macooler shows live temperatures and lets you spin the fans up to cool your Mac under load — then hand control back to macOS. Free and native.

Controlling your fans is safe when you follow two rules, both of which a good app enforces for you:
- Only raise the speed, never lower it below Apple's minimum. Faster fans cool your Mac and can't hurt it. Forcing the fans slower than macOS wants is the only risky move — a well-designed app won't let you.
- Hand control back when you're done. There's no need to keep the fans pinned at maximum all day. Use manual control during heavy work, then return to automatic so your Mac is quiet the rest of the time.
Fan control doesn't void your warranty and doesn't modify macOS — it only asks the same controller Apple uses to spin the fans a little faster. To know when it's worth doing, keep an eye on your temperature; our guide on checking your MacBook's temperature shows how.
Frequently asked questions
Can you control fan speed on a Mac?
Yes. On any Mac that has fans — MacBook Pro, iMac, Mac mini, Mac Studio and Mac Pro — a fan-control app can raise the fan speed above what macOS chooses, on both Apple Silicon and Intel. The fanless MacBook Air is the exception.
Can you control the fan on a MacBook Air?
No. Every MacBook Air (Intel and Apple Silicon) is fanless and cools passively, so there's no fan to control. Fan control only applies to Macs that physically have fans.
Is it safe to control your Mac's fans?
Yes, as long as you only raise the speed. Running the fans faster cools your Mac and cannot harm it. A good app never lets you go below Apple's minimum safe speed, and you can hand control back to macOS at any time.
Does fan control work on Apple Silicon (M1, M2, M3, M4)?
Yes. Fan control works on Apple Silicon Macs that have fans, such as the 14-inch and 16-inch MacBook Pro, iMac, Mac mini, Mac Studio and Mac Pro. Macooler is built natively for Apple Silicon.
