Long a staple for PC builders and overclockers, OCCT (OverClock Checking Tool) has helped users push their rigs to the limit and diagnose weak spots for years. Now, with a version tailor-made for Valve’s Steam Deck, OCCT is bringing its robust feature set to the world of portable gaming hardware-no command line or complicated installs required.

OCCT brings pro-level stress testing to the Steam Deck’s portable form factor.

Unlike earlier Linux builds-which could technically run on the Steam Deck but weren’t optimized for its controls or display—this new edition is designed from the ground up for handhelds. That means touch-friendly menus, streamlined navigation, and real-time telemetry that’s readable on the go. At launch, OCCT’s developers guarantee full compatibility with the Steam Deck, with plans to extend seamless support to other Linux-based handhelds like the Lenovo Legion Go S in the future.

What exactly can OCCT do on your handheld? Expect rigorous stress tests for CPU, GPU, and RAM, alongside detailed monitoring of temperatures, voltage, and power consumption. For Deck owners worried about performance dips, battery health, or suspected hardware hiccups, it’s an invaluable toolbox—especially when you’re pushing your device in docked or overclocked modes.

OCCT is making this release entirely free to download and use, with an optional one-time contribution if you want to support ongoing development. It’s a model that mirrors many community-driven utilities, lowering the barrier for tech-savvy tinkerers and casual users alike.

From an industry perspective, OCCT’s arrival on Steam Deck is part of a wider shift: more tools and utilities are making their way to Linux and handheld platforms, empowering everyday gamers to take charge of their hardware. As the portable PC market matures, the expectation for robust, accessible diagnostics is rising—and OCCT is positioning itself at the forefront of this trend.

Handheld gamers can now stress test and troubleshoot with the same tools as desktop users.

Whether you’re a Deck modder squeezing out every last frame or a casual gamer wanting peace of mind, OCCT’s handheld edition could be an essential addition to your utility belt. With more Linux-native apps on the horizon, the Steam Deck and its competitors are looking less like gaming curiosities and more like fully fledged PCs in your pocket.

TL;DR: OCCT is launching a free, Steam Deck-optimized hardware benchmarking app in June, letting gamers stress-test and monitor their handheld’s CPU, GPU, and RAM with pro-level detail. Expect smooth integration, detailed stats, and future support for other Linux handhelds—all in a touch-friendly package.
