PS5 Showing “No Signal”? Yeah… It’s Probably the HDMI Port. And Yes, It’s $199.
If your PS5 powers on but shows no signal, there's a good chance the HDMI…
Your PS5 gets loud.
Really loud.
Like… “Is this a gaming console or a small aircraft preparing for takeoff?” loud.
Then you notice:
The console is hot.
The fan is spinning aggressively.
Games start lagging.
And sometimes… the PS5 shuts off completely.
If your PS5 is overheating, this isn’t normal.
Yes, PS5s run warm.
But overheating, loud fans, or sudden shutdowns usually mean something else is going on.
And most of the time, the causes are actually pretty predictable.
PS5s pull in a lot of air.
That’s how they stay cool.
But they don’t just pull in air.
They also pull in:
If you have pets, this gets worse.
Dog hair.
Cat hair.
Fine dust.
It all gets sucked into the system and collects inside.
One of the biggest problem areas?
Around the power supply unit.
This area tends to trap debris and restrict airflow. Once airflow is blocked, heat builds up quickly.
And when that happens:
This is extremely common.
Especially in homes with pets.
When airflow is restricted, your PS5 has to work harder to stay cool.
So the fan spins faster.
Much faster.
This is when you start hearing:
That loud rushing noise
The constant fan ramping
The console working harder than usual
This isn’t just annoying.
It’s a sign the system is struggling to cool itself.
Left long enough, overheating problems usually get worse.
This one is more controversial, but it’s something seen often enough to mention.
The PS5 uses liquid metal for cooling instead of traditional thermal paste.
Liquid metal works very well for cooling.
But over time, especially when the PS5 is standing upright, the liquid metal can shift away from where it’s supposed to sit.
When that happens:
This isn’t something that happens instantly.
It develops over time.
And while it’s not guaranteed to happen, it’s something that appears frequently enough that many overheating PS5s end up needing a liquid metal correction or replacement.
This is more of an observational pattern than a scientific claim, but it’s seen often, especially in consoles that have been standing vertically for long periods.
If your PS5 is overheating, this is sometimes part of the issue.

You might notice:
Sometimes it starts gradually.
Other times, it happens suddenly.
Either way, overheating usually doesn’t improve on its own.
Even if your PS5 worked perfectly when new, over time:
It’s normal wear.
Especially if:
These factors accelerate buildup.
Sometimes customers assume overheating is related to HDMI or display problems.
While HDMI issues are also common, they’re usually separate.
If you’re experiencing no signal issues, that’s a different repair entirely:

But if your PS5 is:
Overheating is usually the real issue.
When overheating issues are addressed, many PS5s go back to:
Because the core hardware is usually fine.
It’s just struggling to stay cool.
That’s why many people look into:
Instead of replacing the entire console.

A PS5 running warm is normal.
A PS5 running loud, hot, or shutting off is not.
Most of the time, overheating comes down to:
Dust.
Pet hair.
Restricted airflow.
Cooling issues over time.
Sometimes, liquid metal movement contributes as well, especially in vertically standing consoles.
The good news?
These issues are often very fixable.
And once addressed, your PS5 usually goes back to doing what it’s supposed to do.
Gaming quietly.
Without sounding like it’s preparing for takeoff.
If your PS5 is loud, hot, or shutting off, dust buildup or cooling issues are likely the cause. Get your console cleaned and restored to proper cooling.
