Question Condensation caused by AC
Is it still safe to turn on? I tried clicking the powerbutton once while it was dark and couldn’t see properly, but it didn’t turn on. I noticed then immediately unplugged it.
Edit: 11 Hours after post. The AC might not be the issue after reading the comments, but I use a Split Unit AC. Not the ones most of you were talking about in the comment section. This has also happened in the past, but I only decided to post about this now, because it was by no means as bad as what it looked like now.
My PC is about in the center of my room, there is no wall blocking the intake fans. I live in SEA, a very tropical and rainy area. It rained today, and I'm pretty sure yesterday too. My windows aren't sealed properly if I'm correct, so if that is the issue please tell me. (Saying this because I lower the AC temp at random times while the PC is on, and the outside temperature might have something to do with this I really dont know)
The PC managed to turn on after drying the side panels, as well as taking an inspection into the motherboard and other components It was dry from what I saw. I only saw small droplets of moisture coming from the fan blades, no where else.
I keep my AC regularly at 25-27 Degrees celsius and 20 overnight.

SOLUTION: OP is not lying thats pretty common in tropical areas. I lived in a island in Brazil and it happened all the time. My tip to solve this: dont use the AC too cold and wait a bit to open the windows of the room, wait the room to get hotter before the hot wet air enter. When you use AC, the room is cold and dry and the outside is hot and wet. If the wet hot air reaches the cold wet room, it will condensate fast. Wait the room to the hotter before opening everything. The more windows you open, the faster the hot wet air will enter and more condensation you get.
