Version 15 marks another major milestone for OCCT, bringing a host of new features, improvements, and visual upgrades.
OCCT v15 Release

We're thrilled to announce that OCCT v15 is now officially out of beta! A big thank you to everyone who helped us test and refine this release over the past few weeks.

This update includes:

  • The stable release of our new Storage Test and Benchmark.
  • A major 3D Adaptive Test update, with better error detection and a new coil whine detection feature.
  • And finally, the long-awaited return of OCCT skins, with LinusTechTips and Corsair kicking things off!

Storage Test and Benchmark Stable Release

The new Storage Test is now officially stable and available to all users, including OCCT Pro and Enterprise editions. If you missed it during beta, this feature stress-tests your SSDs and HDDs under heavy workloads and high temperatures to validate performance and reliability. However, keep in mind that this test can be very intense for your components and very frequent use can impact your SSD and HDD lifespan, though normal usage poses no significant risk.

Alongside it, we're also releasing our new Storage Benchmark. We didn't try to reinvent the wheel here, instead we aimed to deliver metrics people are familiar with. That's why we built our benchmark model around CrystalDiskMark-style metrics, providing results that are efficient, comparable, and easy to interpret. It will take us some time still to build the database and give you more meaningful comparative data overtime.

With these additions, OCCT continues to evolve toward an all-in-one tool that enthusiasts and professionals can use for reliable data without the need for multiple software.

Major 3D Adaptive Test Update

OCCT v15 isn't just about storage, it's also a big leap forward for our GPU test. Our 3D Adaptive test has been made significantly more demanding and precise than before.

The test works the same as before, but we've improved error detection efficiency. Though you might notice lower frequencies or lower power consumption on some GPU's because the test triggers protection mechanism more aggressively at maximum intensity.

In short: the new 3D Adaptive test pushes your GPU harder, smarter, and catches issues with greater accuracy.

New Coil Whine Detection Feature

One of the more experimental and fun addition in v15 is the new Coil Whine Detection feature.

When working in noisy environments, it can be tough to tell whether a system is producing coil whine. While refining the 3D Adaptive Test, we noticed that in Switch mode GPU fan noise varies depending on load intensity, and thought, “what if we could control that and make the GPU ‘sing’?”

Turns out, we can! We're starting with three different tunes, with plans to add more, and maybe even let you create your own in the future.

It's important to note that results can vary depending on your GPU model and overall configuration, including factors such as the type of coils used on the board, cooling system, and the case.

New OCCT Skins

Yes, you read that right, OCCT skins are back! Some of you might remember the Cooler Master skin. Sadly, that one's gone, but after taking time to rethink how we handle skins and partnerships, we're thrilled to announce their return in v15.

We're launching with two incredible partners: LinusTechTips and Corsair.

OCCT Linus Tech Tips Skin

You can enable their skins directly from OCCT's settings or download their dedicated versions from our download page. If you own a Corsair pre-built PC, you may even find OCCT preinstalled and already rocking Corsair colors!

We have more skins lined up for future release, so stay tuned!

What's Next?

OCCT v15 is just the beginning of this next chapter. We're already hard at work on our next major update, and it's going to be huge! But for now, that's all we can say.

Thank you again for being part of the OCCT community, if you have feedback regarding v15 or OCCT in general, you can reach out to us anytime and join our Discord server to chat with us and other users.
