ASUS shipped GPU Tweak III 2.1.6.0 on July 24, a 112.99 MB maintenance update that zeroes in on four long-standing annoyances: disappearing monitoring graphs, abrupt shutdowns during display resolution switches, rear fans ignoring imported curves on fresh installs, and blocked fan adjustments on recent Radeon cards. The release, available now for Windows 10 and Windows 11 64-bit systems, tackles the kind of real-world reliability gaps that turn a confidence-inspiring tuning utility into a source of frustration.

What Actually Changed

The patch list is short and surgical. Every fix addresses behavior that could break a workflow or undermine trust in the software’s core functions.

Disappearing Monitoring Charts Are Back for Good

Selecting a small number of metrics to watch—say, only GPU temperature and fan speed—could previously cause charts to vanish entirely. ASUS says the bug triggered when monitored items dropped below a certain threshold, though it hasn’t disclosed the exact count or which metric combinations were vulnerable. The only thing that matters for users is this: you can now build a clean, uncluttered monitoring dashboard without losing visibility. The fix applies to the main monitor window, the detachable panel, and the on-screen display—all of which are central to how GPU Tweak III presents telemetry. For anyone who uses the utility to keep an eye on thermals during a gaming session or validate an undervolt, this is a quiet but essential repair.

No More Crashes When You Switch Display Resolutions

A resolution change—whether from a game entering full-screen, plugging in a second monitor, or using remote desktop—would unexpectedly close the application in previous versions. That instability hit at the worst possible moment: when you’re trying to observe behavior during a mode switch. The 2.1.6.0 release stops this crash, though ASUS hasn’t revealed the exact technical trigger. Users who frequently toggle between display configurations should no longer have to restart the tuning utility mid-task.

Imported Fan Curves Now Obey on Fresh Installations

If you’ve ever reinstalled Windows, migrated to a new drive, or simply started fresh with GPU Tweak III, you may have noticed that a carefully saved fan profile didn’t always apply to every fan on the card. Specifically, a rear fan could ignore the imported curve, leaving one part of the cooling solution running on its own unadjusted logic. That defect is now fixed. The correction is particularly relevant for owners of multi-fan ASUS cards, including the quad-fan ROG Astral RTX 5090 and the extreme-power Astral RTX 5090 Edition 20, where thermal control across all fans is non-negotiable. Profile portability just got a lot more trustworthy.

Radeon Fan Curve Adjustments Unlocked (Yes, for RX 9070)

The most confusing entry in the release notes references “RX9700 series” models that were prevented from adjusting fan curves. AMD doesn’t sell a Radeon RX 9700—its current gaming lineup is the Radeon RX 9070 and RX 9070 XT, part of the RX 9000 Series. The mismatch is almost certainly a typo in ASUS’s documentation, as first reported by VideoCardz. The practical takeaway: owners of ASUS-branded RX 9070 or RX 9070 XT cards who had been locked out of custom fan tuning should now regain full control. After installing the update, verify that your fan slider or curve editor works as expected rather than relying on the ambiguous label.

What It Means for You

The value of this release depends heavily on how you use GPU Tweak III.

  • For light-duty monitors: If you simply keep the program running to glance at temperatures and clock speeds, the chart and resolution-crash fixes mean you can trim your metric list without fear and switch displays without the utility vanishing. The software becomes more reliable as a background telemetry tool.
  • For power users and overclockers: The rear-fan curve fix is the headline. When you rebuild a system or reinstall the utility, you can now be confident that every fan follows your custom profile—not just the ones the older version remembered. This matters especially if you’ve spent time dialing in a noise-to-temperature balance across a multi-fan card.
  • For Radeon RX 9070/9070 XT owners on ASUS boards: You’re the direct beneficiaries of the fourth fix. If you’ve been stuck with stock fan behavior because the adjustment was grayed out, the update is essentially mandatory. Note that ASUS’s wording is sloppy, but the real-world identity of the affected GPUs is clear from AMD’s product line.

How We Got Here

GPU Tweak III sits at the intersection of driver, firmware, and Windows display stack, which makes even minor glitches disproportionately disruptive. ASUS has been tightening the utility’s visual and control consistency for months. The immediately prior release, version 2.1.4.0, repaired a Voltage-Frequency Tuner curve that could extend beyond the graph’s borders—another case where the on-screen tools didn’t match the user’s intent. Together, these updates signal a deliberate focus on making existing controls work predictably rather than piling on new features.

This isn’t a coincidence. Multi-fan cooling designs are becoming standard on high-end GPUs, and the ROG Astral line pushes that to four fans with sophisticated per-fan logic. At the same time, users routinely export and import profiles across clean installs or new builds. When a fan doesn’t follow the intended curve, the whole premise of software-controlled cooling breaks down. The 2.1.6.0 patch meets those elevated expectations, at least for the specific scenarios it covers.

What to Do Now

  1. Download from the official source. ASUS hosts the 2.1.6.0 installer through its support channel. The SHA-256 checksum for the 112.99 MB file is:
    EBC2C636EED531A0DB24F3E93912E871F1861F5FC79E0B4BE32835172C9F1654
    Verify it after download if you’re security-conscious.
  2. Save your current settings. Before updating, take screenshots of every panel—clock offsets, voltage, power limits, and every fan curve point. That way you can confirm everything looks identical afterward.
  3. Run the installer and restart. ASUS’s own instructions insist on a full reboot to finalize the installation. Don’t skip it.
  4. Re-import profiles carefully. If you use a saved profile, import it after the restart and then manually check that each fan ramps up and down in response to temperature changes. Don’t assume an “import successful” message means full application.
  5. Test under load. Launch a predictable GPU workload (a repeatable benchmark or a consistent game scene) and watch fan speeds, temperatures, and clock behavior. Keep the tuning conservative during this initial validation—avoid pairing the update with a new overclock or aggressive undervolt.
  6. Trigger a resolution change. If you frequently switch displays or play games that toggle full-screen modes, do it now while GPU Tweak III is open. Confirm the app stays alive and the on-screen display continues to function.

Outlook

ASUS didn’t promise a blockbuster feature in 2.1.6.0, and it didn’t deliver one. That’s precisely the point. The update makes GPU Tweak III more dependable for the daily tasks that enthusiasts actually perform—monitoring a lean set of sensors, surviving display transitions, and honoring custom fan profiles across rebuilds.

Looking ahead, the pattern of small, corrective releases suggests ASUS is listening to community feedback on stability. Owners of the latest quad-fan and high-power Astral cards should especially keep this update in their toolkit. There’s no word yet on a larger interface refresh or expanded hardware support, but if the development team stays this focused, the next release will likely continue the cleanup. For now, the responsible move is to install version 2.1.6.0, validate your configuration, and enjoy a tune-up that actually tunes.
