Xbox Series X Overheating: Thermal Paste Replacement Cost and Fix

Signs your Xbox Series X is overheating

• An on-screen warning that the console is too hot, asking you to check where it's placed.
• It switches itself off mid-game, usually in demanding games.
• The fan is loud even on the home screen, or gets louder month by month.
• The air coming out of the top vent is very hot, not just warm.

One warning on a hot day with the console in a cabinet isn't a fault. The same warning every week with plenty of space around it means the cooling inside isn't keeping up.

Why does an Xbox Series X overheat?

Usually dust packed into the heatsink fins and fan, and thermal paste that has dried out over the years. The Series X pulls air in underneath and pushes it out of the big vent on top, so a closed cabinet, or anything sitting on that vent, makes it worse. If it overheats with plenty of space, the cause is inside.

What a thermal paste replacement involves

1. We diagnose first: fan, heatsink, paste and anything else we spot. If it needs more than you booked, we tell you and wait for your OK.
2. The console is stripped down to the cooling assembly.
3. Packed dust comes out of the heatsink fins and off the fan blades.
4. The dried paste is scraped off the processor and fresh thermal paste goes on.
5. It's rebuilt and tested under load before it goes back, with photos or video of the work on request.

This is the internal service. Our ultrasonic exterior clean is a different, cosmetic job for the shell and panels, and it does nothing for temperatures. You can have both done in the same visit.

Xbox and PS5 overheating repair prices

Loud fan: new paste or a new fan?

Book the overheating repair. A loud Xbox fan is almost always the fan running flat out because heat can't get through a dusty heatsink and dried paste. The technician checks the fan while the console is open, and if the fan itself has failed, they quote a replacement before doing anything extra. No fix, no fee.

How long does it take?

The repair takes 2-3 hours on the bench. Standard turnaround is 1-3 working days once the console is with us, dropped off or posted. Same day is possible with our priority service: a priority fee applies, and it depends on the fault, parts and how busy the workshop is, so ask the team when you book.

Posting it from elsewhere in the UK? Add a prepaid Royal Mail tracked label at checkout and you get a QR code to show at any Post Office, so there's nothing to print. It comes back to you tracked, free. When we're very busy a repair can take up to 7-10 working days, and we'll tell you if so.

What you can do at home first

1. Give it space, especially above the top vent. Take it out of closed cabinets.
2. Don't stand anything on the vent: no games, no headset, no soundbar.
3. With it unplugged, hoover the outside of the vents gently with a brush attachment.
4. Don't blast compressed air into the fan. It spins the fan far faster than it's made for and pushes dust deeper into the fins.

Still hot or loud with plenty of space around it? The dust and the paste are inside, and that's the repair.
