Right now I'm outside with my friend's switch and I just noticed that the exhaust fan is going crazy. It seems like one problem after the other keeps appearing on this thing.

What could cause the exhaust fan to do this? Is it possible that it's failing? It's really concerning.

It's quite common for people to get surprise on how fast that fan can spin

When I had my own switch I could play pretty much any game in handheld mode and it wouldn't be anywhere near that loud.

#

However, that was many years ago

But what you should know is:

  • It should adjust the speed base on the temperature the sensor inside is detecting.
  • Heavy scenes in certain game will force the Switch to generate a lot of heat.
  • There's a safety limit. When the Switch reached a certain dangerous temperature, it will automatically shut off with an overheating error.

This is a very demanding game for the hardware, I assume.

#

Well, do you see the same issue with other games?

rich elk
#

I can't play other games on the switch, I'll ask my friend to try one out because he has the cartridges at his house.

#

I only have my own copy of Tears of the Kingdom

#

But I'll ask him to try.

#

Thank you for at least reassuring that it isn't too serious.

Go on the eShop

#

search for Dragon Quest Builders 2's demo

#

that game will always and always make the Switch fan get into "jet engine" mode

rich elk
#

Sounds like a perfect way to kill your switch lol

grim oak
#

I can't believe I play through that entire game ._.'

#

but yeah...

rich elk
#

Is it healthy for it to go into jet engine mode for a long period of time?

#

Could that potentially have consequences in its lifespan?

Fan has age, they will die eventually

#

thanksfully, easy to replace

#

Your question is common enough, I made it into a tag x)

VENTILATION & FAN

§ The Switch vents its internal heat by sucking air in from the intake vent on the back, and then blow out by the fan on the top vent. While the console is on the dock, air intake go through a channel under the cable cover. Airflow chart.

■ Good practices for ventilation
• The ambient temperature around the console should be kept at 5 to 35C.
• Keep the vents clear for better airflow.
• Do regular cleaning on the vents with a squeeze blower or compressed air can.
• Turn off the Switch when you have to store in enclosed space for a while.

■ Signs of concern
• The fan is making abnormal, grinding noises. It may be broken or has worn out and need to be replaced.
※ Note: The Switch fan can be surprisingly loud. It can get around 30-35 dB, but that is normal.
• The Switch showed an overheat error and shutdown (SoC reached 67°C). This is a safety feature to protect the components from reaching dangerous temperature threshold. Your Switch may have issue venting the heat.

■ Solution
You can open up the Switch to clean the fan internally, but putting in a new fan is the best solution. It is something you need to do eventually, and it's one way to "refresh" the life-cycle of the console.

Also, good news. My last thread didn't have much optimism about my friend getting his receipt for the switch. He found it, so all he has to do is send it in and hopefully they'll cover the cost of the repair with the warranty.

#

It is under 12 months old.

grim oak
#

Wow, that's great then 😄

rich elk
#

They automatically come with a warranty, right?

#

So 100% he should have a warranty on that

grim oak
#

should be, yeah

rich elk
#

Good.

grim oak
#

but idk how it will work in this case, so good luck to him

rich elk
#

Yeah, I hope things will go smoothly.

grim oak
#

nintendo have their own policies and all that

rich elk
#

Yeah

#

Hopefully things will go well, that's all I really needed for now. Thank you again for all your assistance. Have a good day.
