If you are handy, a simple DIY pad can hit your goals on the cheap... 🔧 A single large case fan fed from USB, a sheet of stiff mesh, four rubber feet, and a little patience will get you a low RPM mover that fits a that model inch chassis without buzzing. I run mine at five volts so it is essentially silent on the desk and it still trims a few degrees. 🤫 Works great.
Mind the current draw from your that model port. Some fans try to pull more than half an amp at spin up which can cause strange pulsing or a clicky start. An inline USB switch or a powered hub solves that and gives you a quick off for late nights. Keep the LEDs disconnected if the fan has them or just tape them, and you get dark and cool without the leaf blower vibe. 🌙
Use a time boundary, state it once, then leave. Many won't notice soft cues, so add motion—turn, pack, stand. Some feelings may still get bruised; clarity is kinder than lingering.
