Semiconductor Phone &
Laptop Coolers — Active TEC Cooling
Beyond standard fans. Our Thermo-Electric Coolers (TEC) act as miniature solid-state refrigerators, forcing heat transfer through the Peltier effect to keep core temperatures below ambient even under maximum load.

Not sure which technology is right for you?
TEC is superior for high ambient temperatures, but fans are more energy-efficient. Compare the physics behind both solutions.
KryoZon Phone Coolers are built for the moments your phone taps out — a Genshin Impact boss fight in the 40th minute, a 3-hour IRL livestream on a summer sidewalk, or a 4K ProRes shoot where the camera app force-closes right before the best take. Every cooler in this collection uses active semiconductor (Peltier / TEC) cooling to drive back-plate temperatures 15–20°C below ambient, not just blow warm air around.
Pick the right model for how you use your phone
- S9 Fanless Liquid Cooling — Silent, fanless TEC + liquid cooling loop. Zero motor noise means clean audio for podcast recording, ASMR, and mic-sensitive shoots. The pick for content creators and audio-critical workflows.
- S6 Cooler Stand for Live Streaming — Integrated stand with adjustable viewing angle and 1/4″-20 tripod thread. Runs hours-long streams and vlog shoots without dropping your phone or your framerate. Best for Twitch / TikTok streamers and mobile vloggers.
- K12 Ultra-Light Magnetic — 65g MagSafe-compatible travel cooler. Snaps on, slides in a pocket, works through phone cases. For mobile gamers, frequent travelers, and anyone who wants cooling without a brick strapped to their phone.
Why semiconductor cooling beats fan-only phone coolers
Stick-on fan coolers blow room-temperature air at a 45°C phone back — if the room is 28°C, your phone's ceiling is still 28°C. KryoZon's TEC modules actively pump heat away from the contact plate, dropping it below ambient. The result: a Snapdragon 8 Gen 3 or A17 Pro that keeps its sustained clocks instead of throttling to half-speed after 15 minutes of gaming.
Who these are for
Mobile gamers (Genshin, CoD Mobile, PUBG, Wuthering Waves), IRL and vertical streamers, phone videographers shooting 4K/ProRes, and anyone whose phone has ever shut down its camera with a "device too hot" warning.
