Desktop forming condensation inside - Help

[RnC_]

Hi everyone

I live on a island so the climate is humid, and today when I was going to clean my desktop I noticed some kind of water on the I/O cover, on the back of the Gpu (backplate) and on top of the case (inside, was dry). 

 

PC specs:

Asus Rog Strix B360-f gaming;

i5-8400;

Gigabyte 1660 super;

NZXT S340;

Intake fans: 2x Noctua NF-A14 140mm;

Output fans: 2x In Win Polaris 120mm.

 

I use the stock Intel cooler and have set up the case fans for a positive pressure, right now since the weather here is still warm during games the CPU gets around 70°C and the GPU around 75°C. 

I've had this PC for a year and a half and I never had this problem before, to everyone who experienced this before or has any hints I would appreciate it.

Thanks. 

 

I was playing Forza Horizon 4 just today and the PC was working just fine.

Looks like water came inside the case somehow. I would not bet on condensation, there would be a lot more droplets on the components. What's your humidity and temperature like at the moment?

are you sure its water, looks like cpu fan leaked lubricant ?

The temperature here is around 22°C and the humidity can go from 70-99% on the worst days

It doesn't smell like anything or even get my finger dirty
