Your laptop is overheating if…

The fans are constantly loud or screaming
It’s uncomfortably hot to touch, especially underneath
It slows down (throttles) under any real load
It shuts off on its own, often mid-task
Games or video calls cause sudden restarts
It’s been years since it was last cleaned inside

The straight answer first

Most overheating comes down to two things: years of dust clogging the cooling fins, and thermal paste that has dried out and stopped transferring heat. Both are straightforward to fix and make an immediate, obvious difference.

Left alone, chronic overheating shortens the life of your CPU, GPU and battery. Getting it sorted early is one of the cheapest ways to protect the machine you’ve got.

How it works

Simple, honest, and you approve the price before any work begins.

Find the heat source

We check temperatures under load to see whether it’s dust, dried thermal paste, a failing fan or a blocked heatsink.

Clean & repaste

We open it up, clear the dust, replace the thermal paste with quality compound, and service or replace the fan if needed.

Verify it stays cool

We retest under load to confirm temperatures and clocks are back to normal — no more throttling or shutdowns.

Frequently asked questions

How much does it cost to fix an overheating laptop?
An overheating fix — internal cleaning and fresh thermal paste — starts at $59.99. If a fan needs replacing, we quote the part first. You approve the total before we begin.
Why does my laptop get so hot and loud?
Almost always dust clogging the cooling system and dried-out thermal paste. Both stop heat escaping, so the fans spin harder and the laptop throttles or shuts down. Cleaning and repasting fixes it.
Is overheating actually damaging my laptop?
Over time, yes — sustained heat shortens the life of the CPU, GPU and battery, and causes throttling and crashes now. It’s worth addressing early.
How long does the repair take?
A clean-and-repaste is often done within a business day or two. If a replacement fan or heatsink is needed, timing depends on the part, and we’ll let you know.
How often should a laptop be cleaned inside?
For most laptops, an internal clean and repaste every couple of years keeps temperatures healthy — sooner if you game hard or live in a dusty or pet-filled space.
