AC And PC help

[Sir Judgementz]

hi all i have my pc on an L desk. and theres an ac in the window blowing on the pc and the room. like in the picture. is this safe for the pc?

Generally speaking, yes it is 

I would pay more attention on the height of the monitor (or TV) compared to your sitting position though
Gotta love your neck after all (unless you're over 190cm, which is understandable or place some distance when gaming with your cool red controller)

Mostly I would say it is safe.

 

The only thing that I think could be bad for it is if you have your PC off and the AC blowing on it cools the case/components.  Then when the AC stops the ambient air starts to condensate on the PC itself.

 

That is the worst case I can think of that could be an issue.  If the PC itself is on though when the AC is running, I think that would be a pretty much non-issue though as the PC likely will remain above ambient temperature.

Circulate the air in the room with the aid of a fan, if possible vent hot air from pc out of room. This will aid in reducing room hot spots and condenstation build up. If you can exchange the whole rooms air with fresh its better but in consumer sense is unrealistic. Recirculated air can lead to higher humidity levels over time. Use Dry mode on AC or a dehumidifier can also help. Stick to AC units that are non-condensing (this means it doesn't introduce moisture back into the air).

Keep the ambient relative humidity between 40% and 60% to minimize risks.
Consumer computer parts are rated for 20%–80% relative humidity non-condensing during operation.
A Hygrometers will measure humidity, Condensation sensors will measure on surface level (like a pc motherboard)
Non-condensing means the humidity isn't liquid on surfaces (moisture in the air remains vapor)

What Is "Non-Condensing"? in terms of air conditioners and PC components explained by ChatGPT

What Is "Non-Condensing"?

"Non-condensing" means that moisture in the air does not form into liquid water on a surface. For condensation to occur, the air's dew point must be reached. The dew point depends on the air's temperature and relative humidity:

• High relative humidity + cooling below dew point = condensation.

• For example, if the air is humid and cooled rapidly (like by an air conditioner), water vapor condenses into liquid water on surfaces.

In the context of electronics, "non-condensing" ensures no water droplets form on or inside sensitive components, as this could lead to corrosion, short circuits, or other damage.

Does an Air Conditioner Condense?

Yes, air conditioners (ACs) condense water as part of their cooling process:

1. How Condensation Happens in ACs:

   • AC units work by passing warm, humid air over cold evaporator coils.

   • The cold coils cool the air below its dew point, causing water vapor in the air to condense into liquid droplets.

   • This liquid is collected in a drip tray and drained away.

2. Air Leaving the AC:

   • The air exiting an air conditioner is cooler and less humid because moisture was removed during the cooling process.

   • However, the degree of dehumidification depends on the AC’s design and settings.

Why This Matters for Cooling Computers

While air conditioners lower humidity, they don’t remove all moisture from the air. If the cooled air comes into contact with a surface (like computer components) colder than the dew point, condensation could still form. This is particularly risky if the AC air is directed straight into the computer.

It's totally fine, you're worrying way too much. My old system I have it directly next to an AC, used it for 8 years until I decided to upgrade it.
