Environmental conditions and motherboard

Separate area for niche lag issues including unexpected causes and/or electromagnetic interference (ECC = retransmits = lag). Interference (EMI, EMF) of all kinds (wired, wireless, external, internal, environment, bad component) can cause error-correction latencies like a bad modem connection. Troubleshooting may require university degree. Your lag issue is likely not EMI. Please read this before entering sub-forum.

Environmental conditions and motherboard

Post by Anonymous768119 » 28 May 2022, 19:28

Just received a link to this interesting thread on reddit.

https://www.reddit.com/r/techsupport/co ... urce=share

The guy discovered by coincidence that after using a hairdryer (which was designated to blow dust away), he could finally boot his PC. After several trials he found out that it is all about high RH in his place. Starting AC eliminated the problem, so he excluded any potential issues from the mains.

In 2013 somebody discovered the same.

https://rog.asus.com/forum/showthread.p ... -quick-fix

It allowes me to think, that RH has much more impact on our PCs that we realize. My performance in games is much better during dry, summer days when RH drops below 50%. I remember a week with consistently good inputs and hitregs which last exactly after first rain. The same was happening during cold and dry winter days. I immediately noticed the difference in gaming when it came to snowmelt. CSGO and everything else was just unplayable and RH in my room was around 80% and 95%+ outside. Funny thing is that by following RH from weather forecasts in my city I could estimate if it's worth to start any game and with very high probability I was right.

Another thing is that crystal oscillators are highly sensitive to environmental conditions like too high or too low air temperature and relative humidity above 75%. Now the question is if fluctuating frequency in the oscillator can cause the problems with inputs and timings that affect gaming so badly.

Point a hairdryer to a motherboard and share your observations.

Not true. Google it TCXO

Are you checking humidity inside your PC, not in the room? You will be surprised; it will be different.
But, I am thinking in your room, the humidity is less than 70, except if you are playing in the Turkish bath.
I am not google a lot, but easily found with 85% humidity level:

You can try, but anyway, this nothing changed.

It doesn't matter, front fans are blowing moist air inside. Problems can appear also when ambient temperature is significantly higher than temperature inside PC chasiss (dew point).

RH level in my building is unnaturally higher and there can be many factors causing that ie. insulation. Air circulation is pretty low aswell so very often I feel like in a jungle. Healthy RH level for PCs is between 45-55% and in my apartments it rarely drops below 70%. When it dropped below 50% outside I had so far best gaming experience ever but in my region it happens very seldom. I am pretty sure there must be correlation.

@Chief Blur Buster

Your opinion and experiences are very welcomed because I can see that it was never mentioned before. Maybe you have something interesting to add.

Guys, I'm in shock! My input lag and how I feel the game depends on the level of finding my pc from the water level! After moving my computer down to the floor, I noticed that my mouse started to feel much better! I do not know how to explain it, I do not have any scientific data, but I give a tooth that it is so.

Was that supposed to be funny or something? No wonder why this forum slowly becomes a trolling center.

What makes you think I'm joking?
Why don't you trust my research?
If you believe that humidity affects the operation of the PC, you should have the fact that the distance from sea level affects too. You can't deny it any more than dirty electricity.

The tone of your comment suggests it clearly.

Believe me or not but it took years for me to notice that. RH level below 50% gave me the best results however I still can't confirm if it's about PC itself or anything else.

When you start digging in the Internet you can see hundreds of topics regarding influence of humidity on PC. Second thing is that I was totally unaware of vaping for months in front of my PC which is pretty harmful for electronics. Need more time to investigate.
