I eventually purchased a humidity sensor. When the forecast mentioned 90% humidity, 23°C, rain, the indoor level stayed below 71%. So it seems okay? I’m not sure about high humidity on very hot, humid days, and I won’t know until next summer. Thanks for your advice! ____In short____ PCs can be affected by moisture. If the air is too damp, it might cause problems over time. Monitoring it helps you decide if a dehumidifier is needed. Even though I’m saving for a new GPU, I want to protect my current system. My old PC has never had strange issues, and mine is still running well—though Intel CPUs are having some stability problems lately. I noticed condensation sometimes in the summer, mainly around cups or the toilet bowl with cold water inside, or on the window sill during winter. But I don’t recall it often. There’s also mold in the basement. Edit: Maybe a bit of moisture on metal parts near my window in summer. ____Further info____ The lake is about a 16-minute walk away. It’s freshwater, not saltwater. Someone mentioned their PC wouldn’t power on. My area isn’t tropical like the Philippines, but I’m experiencing temperatures between 29°C to 32°C with humidity levels from 65% to over 80%. That’s higher than usual. Why are the operating temps low even though the humidity is high? I read that servers can handle up to 80% RH without issues, but my PC seems sensitive. I found operating humidity specs for a server motherboard—operating temps go up to 80% (non-condensing). But why are they so low? I thought CPUs could reach 80 or 90°C before throttling. https://www.gigabyte.com/Enterprise/Rack...ifications I keep my ceiling fan on, sometimes with the window open. I’m not keen on using an AC unless it’s really necessary because of power consumption. I can’t locate humidity data for most PC components, but I saw one for a server. Operating humidity stays around 80% (non-condensing). Why are the component temps so low? I expected higher temperatures if the system was stressed. If you want to prevent moisture damage, consider placing baking soda near your PC or using silica packets inside the case. Just make sure they don’t attract water. You might want to check how much moisture is present on metal surfaces around my room’s window sill. Let me know your thoughts!
The ideal temperature range is around ambient conditions. Devices can operate at higher temps up to 90-110°C, but they require cooler surroundings to release heat efficiently and stay within limits. It seems servers struggle to cool past 35°C, which explains the safe upper bound. If humidity was damaging your system, you’d likely have felt it in older models.
Copper components without nickel plating are prone to rusting over time. More importantly, items like guitars need protection from moisture; exposure can damage the wood and cause it to become damp, similar to a tree in a humid environment.
I usually write quite a bit—it's just how I am. Is it too much for readers to follow? The forecast shows humidity at 86%, probably dropping slightly but staying high at night. It seems the humidity chart yesterday looked similar. It’s not helping that both outdoor and indoor levels match.
Yes, you can check for uncoated copper by looking at the physical components or using specialized tools. Relying solely on quality parts is a good approach but not foolproof.
Humidity levels need careful control for electronics. Aim for around 50% to avoid static problems and prevent shorts from excessive moisture. Using dehumidifiers can also help cool things down, as your body sweats more efficiently and air’s ability to conduct heat drops with higher humidity. Concerning rust, it mainly affects steel parts like brackets and supports on motherboards. Most of these are designed to resist rust, though results vary. You could try DIY rustoleum solutions for affected areas, but keep in mind that many components need some conductivity to function properly—like the ground screws on the motherboard or PSU connections. Even if you replace them, threading might remove the protective coating, so it’s a delicate balance.
It probably shows signs of copper or brass exposure, though light rusting shouldn’t cause issues. Checking your previous PC can reveal how parts behave with age and similar environments.
It makes sense to review your older system. Your main PC is still functional, though it runs slower these days. Likely the issue stems from replacing the SSD with a much slower HDD.
You're aiming for about 50% humidity, which is a good target. That usually means using a dehumidifier to keep the air balanced. It’ll help you save money in the long run!
