I'm concerned about keeping my PC safe this winter with the humidity dropping to around 30% or even less. I live in the northeast U.S., and it's getting quite cold and dry. I understand low humidity can increase the risk of electrostatic discharge (ESD), which worries me. My room is currently at 29% humidity, and I'm considering getting a humidifier, but I'm unsure if that's a smart move given my PC setup. I have a powerful build with a 5090 graphics card and a 9950x3d processor. I'm looking for tips or routines to ensure my PC remains safe from electrical discharge as we go through the next few months. Just for context, I won't be opening up my PC in this dry environment—if I need to, I'll relocate it to a different room. Thanks!

As long as you’re not plugging in peripherals or touching the inside parts while the PC is on, you should be good. For handling moisture, you can place a glass of water near a radiator or vent to help with evaporation; that could raise the humidity a bit without much hassle.
If you aren't opening your PC, you should be fine. The case is grounded through the PSU, so static electricity will generally be directed away from sensitive components. Just make sure that when you do work inside it, you’re grounded properly to prevent any issues. Keeping the case closed and avoiding contact with the inside while your PC is running will help too.
I appreciate the tip! One concern I have is that my UPS is right next to the vent, which might not be ideal. The PC is about 3-4 feet away, but I'm worried about any potential issues.
