My computer runs about 25-27 °C, which is okay during Winter, because I keep the house at about 20 °C. I am a bit concerned that it might be too cold during the summer months and that condensation may form inside my computer, thus exposing components to water, essentially making clouds and rain in my computer.

There is no way I can afford to keep the AC any cooler, any ideas?

Around 25°C is a perfectly safe temperature for your computer to run at. Since the computer runs at a warmer temperature that the surrounding environment it is unlikely to attract condensation.

If humidity is a concern:

  • Try to avoid leaving the computer turned off for long periods at a time
  • Make sure the case is closed.

You could look into a dehumidifier but this is most likely unnecessary unless you are in a tropical climate and would cost to run. As mentioned above it is usually heat rather than lack of it which is a problem for electronics.

There's no such thing as too cold when it comes to electronics.

Humidity (the amount of water in the air) can be a problem though. But note that if you have your computer case closed, cold alone will not cause condensation to appear. Condensation will only appear if the water in the air gets in a hot/cold situation. But with the case closed, there shouldn't be any water in the air in the first place. Secondly, you need a really high humidity for this to be a problem.

You state "computer" and not laptop, I believe anyone would assume this to be a desktop or tower PC. This is important because you may have some issues if you were to tote a portable item from a cool environment to a humid one.

That being said, a PC that resides in an environment will have that environments ambient temp and relative humidity when it is not operating. While powered, the internal environment of the PC would get warmer, not colder.

You state you have and AC and do not wish to run it colder; then don't. Half the function of the ac is to not only reduce the temp, but reduces humidity in the area it is operating in.

So for cooling any further to reduce condensation damage, it will not make a difference while the PC stays in the same environment.
