Dust acts as a thermal insulator, blocking airflow through heatsink fins and triggering CPU/GPU thermal throttling, which causes significant frame rate drops and slowdowns. A 20-minute cleaning session — powering down fully, discharging capacitors, and blasting compressed air through coolers against the intake direction — can restore sustained boost clock speeds and stable temperatures. Using MSI Afterburner to monitor temps before and after validates the improvement. Maintaining positive case pressure with filtered intake fans helps slow dust accumulation between cleanings. ## Full article daily.dev links to this article rather than hosting it.
