Every summer the same thing lands in the Fentech workshop: consoles that were grand all winter suddenly getting loud, throwing up an overheating warning, or shutting themselves off mid-game. If your PS5 or Xbox has started sounding like a hairdryer during this warm spell, or you've seen the dreaded "Your PS5 is too hot" message, you're not imagining it. Usually it's an easy fix, as long as you catch it before it turns into anything serious.
Why summer is the tipping point
A console cools itself by pulling cool air in, running it over a hot heatsink, and blowing the warm air back out. There's a bit of headroom built into that, but only a bit.
When the room itself is warm, the air coming in is already warmer, so there's less margin to play with. Add two or three years of dust caked onto the fan and heatsink and airflow drops right when the console needs it most. That's why a machine that was perfectly happy in January starts struggling in a July heatwave. It isn't broken. It's being asked to cool itself with one hand tied behind its back.
The easy wins (do these first)
Before anyone opens anything up, sort out the basics. A surprising number of "faulty" consoles are just badly placed:
- Give it space. Pull the console out of any enclosed cabinet or shelf cubby and leave a good few inches of clear air on every vented side. Consoles boxed into media units are the most common overheaters I see.
- Stand a PS5 upright on its base, or lay it flat with clearance. Just don't have it lying on a rug or carpet where the intake vents get smothered.
- Mind the Xbox Series X vent. That big grille on top is the main exhaust, so never rest anything on it, and keep it clear of shelves overhead.
- Blow out the vents. Short bursts of compressed air across the vents and dust openings clear the loose stuff. Kingston's cooling guide is a sensible walk-through of the placement and airflow side of things.
Sony actually built the PS5 to be cleaned. The removable side panels and little triangular dust catchers are there on purpose, and taking the panels off to clear them doesn't void your warranty.
When it needs more than a dust
If you've done all that and it's still overheating, the gunk has usually worked its way deeper: matted into the fan blades and packed through the heatsink fins where canned air won't shift it. At that point it's a proper strip-down and deep clean, and often the original thermal paste has dried out too. iFixit's PS5 cleaning teardown shows just how much dust hides inside a console that looks spotless from the outside. Fresh thermal paste and a cleaned-out heatsink can drop running temperatures dramatically and bring the fan noise right back down.
Same goes for a gaming PC
On a PC the story is the same. Dust-clogged coolers and old paste cause thermal throttling, and you notice it as your frame rate dropping off in the heat for no obvious reason. A summer clean-out is worth doing there too, and I do them alongside building and upgrading rigs.
What to do this week
Summer overheating on a PS5 or Xbox nearly always comes down to warm air plus dust choking the cooling. Move it somewhere with clearance and clear the vents first. If it's still running hot after that, it needs a proper deep clean and fresh thermal paste, and that's a cheap job compared with what heat does to a console left to cook all summer.
