Handheld consoles have changed the way we game. From tearing through dungeons on the go to drifting on the couch, devices like the Nintendo Switch 2 and the Steam Deck have given us console-quality performance in a portable package. But with great power comes one big challenge: heat. Long gaming sessions, 4K visuals, and high-performance workloads push these handhelds to their limits, and without the right accessories, you risk frame drops, shutdowns, or worse—hardware damage. That’s where a cooling fan steps in as the ultimate sidekick.

Let’s dive into three next-level cooling accessories from JSAUX that keep your handheld rig running smooth, cool, and battle-ready.

JSAUX Cooling Fan for Nintendo Switch 2 

If you’re rocking the Nintendo Switch 2, you already know its ability to output stable 4K visuals when docked is a total game-changer. But with all that power, things can heat up fast. The JSAUX Cooling Fans for Nintendo Switch 2 are designed specifically for this system, making sure your console doesn’t choke when the action gets intense.

This Nintendo Switch 2 cooling fan attaches seamlessly, fitting like it was made by Nintendo themselves. Whether you’re grinding through marathon RPG sessions or smashing through high-load action titles, it keeps the system’s temps steady, protecting both performance and hardware. A huge plus here is the integrated PD 3.0 fast charging that juices your console while keeping it cool, so you don’t have to choose between performance and playtime. Think of it as running nitrous while still cooling the engine—every lap stays smooth.

JSAUX Cooling Fan for Steam Deck 

Steam Deck players know the struggle of heat during extended play. Whether you’re loading up a massive modded Skyrim save or running Cyberpunk at high settings, the temps climb fast. Enter the JSAUX cooling fan for Steam Deck (GP0200), tailor-made for both LCD and OLED models.

This accessory doesn’t just cool; it gives you control. The adjustable speed fan means you can customise your cooling level depending on what you’re playing. Going light with an indie platformer? Low speed will do. But if you’re pushing Elden Ring or Baldur’s Gate 3 for hours, crank that fan up and feel the heat vanish. Plus, the rapid cooling kicks in quick, dropping temps noticeably so your Deck never skips a beat.

What really sells it is the 4–6 hours of battery life on just a 1.5-hour charge. That means you can go for a full raid night or long road trip gaming without worrying about overheating or the fan dying mid-boss fight. For handheld warriors, it’s like having your own personal cooling crew on standby.

JSAUX Universal Extensional Cooling Fan 

For gamers who want flexibility, the JSAUX Universal Extensional Cooling Fan (GP0201) is the powerhouse option. Also designed for the Steam Deck’s LCD and OLED versions, this unit offers the same long-lasting cooling sessions with adjustable fan speeds and quick recharge times. But the best part? Its universal adaptability.

While it shines on the Steam Deck, this fan can easily serve as a backup solution across multiple handheld devices. The fast cooling system drops temperatures rapidly, keeping your console from hitting those dangerous thermal spikes that can end a good run prematurely. If you’ve ever had a game session cut short by thermal throttling, this accessory feels like insurance for uninterrupted immersion.

The ergonomic design and compact form also make it travel-ready. Toss it in your bag with your Deck, and you’re armed with portable, customisable cooling wherever you go.

Why Cooling Accessories Matter

Some gamers think cooling add-ons are just “nice-to-have” extras, but the truth is, they can make or break your experience. Overheating doesn’t just slow performance—it risks damaging your device over time. And when you’re dropping serious cash on handheld rigs like the Switch 2 or Steam Deck, investing in proper cooling isn’t optional; it’s smart gaming.

These JSAUX accessories are designed with gamers in mind. From fast charging on the Switch 2 fan to adjustable speeds and long battery life on the Steam Deck options, they all solve the same core problem—keeping your gear cool while you chase victory laps, grind dailies, or explore endless open worlds.

Final Verdict: The Best Cooling Fan for Gamers

At the end of the day, keeping your handheld console cool is about more than comfort—it’s about performance and longevity. The JSAUX lineup of cooling fans nails that balance, giving you practical heat management with gamer-first features.

So, whether you’re seeking Switch 2 stability, Steam Deck-specific performance, or a universal option that adapts to your setup, there’s a solution here that’s worth every cent. If you’re serious about handheld gaming, investing in the best cooling fan is the ultimate move to keep your adventures running smooth, cool, and lag-free.
