JSAUX Cooling Fan for Steam Deck OLED 8–15°C drop

The JSAUX Cooling Fan for Steam Deck is a compact cooler with an integrated stand that helps keep Valve's handheld under control during extended sessions. It channels air directly into the Steam Deck vents to boost internal circulation, cutting temperatures notably within minutes and letting you play without frequent thermal throttling.

Key features

This accessory blends a fan and a built-in stand so you can prop the console while charging or streaming. The adjustable knob lets you set fan speed from 0 to 100% and balance airflow against noise. According to the manufacturer, the unit can lower device temperature by about 8–15 degrees Celsius after 4–8 minutes of operation, which can help sustain peak performance during demanding play.

Best use cases

This fan is useful when you need consistent cooling while gaming on a desk or lap.

Bear in mind that higher speeds increase noise, which is normal for compact cooling units.

Who it’s for

Worth considering if you play graphically heavy titles on a Steam Deck or use the console for longer sessions and want a simple way to reduce heat and maintain performance. It’s a practical add-on for casual streamers or players who prefer a hands-free set-up while charging or docked.
