Hey folks,
I'm experiencing a frustrating issue with my Gigabyte M27Q3 monitor (27", 1440p, 300 Hz). After I power off my computer for the night, I sometimes hear intermittent crackling and popping noises coming from the back of the monitor for about 30 minutes. It's not a constant sound, more like random "crack... crack..." noises. I get that this might be normal due to thermal expansion and contraction, but it happens right when I'm trying to sleep and can be quite startling.
I'd love to hear from anyone who has dealt with this issue and found a solution. I've thought about placing a small USB fan under or behind the monitor to help with cooling. Would that make a difference? I also had a similar experience with an ASUS TUF Gaming monitor and ended up returning it because of this noise. It seems like this problem might be common with 1440p high refresh rate monitors.
If anyone has successfully reduced this noise, your advice would be greatly appreciated!

Lowering the refresh rate can help with heat. But I tried reducing my monitor to 60 Hz and still heard the noises. I just don’t think it’s worth it to limit the monitor’s capabilities after paying for high refresh rates.
My 4k monitor also makes annoying noises after turning it off. Sometimes it’s just thermal expansion, like a car cooling down... it’s been doing this for years. If you’re in a cooler climate, it can be even more noticeable. The best advice? Just try to hit the sack earlier!
I’ve had a similar "crack... crack..." sound with my monitor too. One workaround that helped me was shutting down my PC about an hour before I go to bed. I know it’s not ideal, but it has made a difference for me in dealing with the noise.
I believe the material and temperature difference are big factors. I notice my Samsung TV does the same thing. When it’s warm, it expands and then contracts, and these noises can happen. Any temperature fluctuations, like opening a window, can make it worse.
You could try adjusting any loose screws on the monitor's case and maybe gently flex the plastic. Sometimes that helps reduce the sounds.
