Laptop fan sounds like a jet engine

The fan isn't the problem. The fan is the alarm. Something is hot, and the little blades are doing everything they can.

Verdict

Fix it

— this is one of the cheapest, highest-value jobs on the menu. A jet-engine fan almost always means dust-packed cooling or dried-out thermal paste, and both are what the $99 tune-up exists for.

What's actually happening in there

Years of dust caked in the heatsink fins. Air can't move, temps climb, the fan screams. This is the #1 cause on any laptop over two years old.
Thermal paste that dried to chalk. The paste between the chip and the heatsink is a wear item; when it dries, heat stops transferring and the fan fights a losing war.
A dying fan bearing. Rattling or grinding alongside the roar points here — the fan itself gets replaced, quoted before we start.

What it costs

The tune-up is $99 flat — thermal paste, fan cleaning, dust removal, and a speed check after. If the fan hardware itself is failing, replacement is quoted up front (the cost guide lists the realistic fan-replacement range). You approve everything before work starts.

Why you shouldn't live with it: a laptop that runs hot for months is slowly cooking its battery and its board. The roar costs you $99 today; the ignore-it bill is usually a dead machine later — and it's why so many "my laptop just died" stories have years of jet-engine noises in their history.

Thirty seconds of self-check

Using it on a bed, blanket, or couch? Soft surfaces block the intake vents and every laptop roars. Try it on a hard table first — if the jet engine goes quiet, that was the cause, and the tune-up is still worth it when you get a chance.

Running hot and slow? Read the slow-computer verdict — the same tune-up covers a lot of that ground.
