Thermaltake Level 20 GT RGB Review

Benchmark Results and Conclusion

We tested the Level 20 GT RGB with our new Intel i9-7900X test platform. For comparison, we brought in the Cougar Panzer EVO RGB, the NZXT H700i, the be quiet! Dark Base 700, and the Cooler Master MasterCase H500M to give you a solid idea where this case stacks up against competitors with similar sizes and feature sets.

The two 200 mm intake fans kept the CPU core temperatures on our Intel i9-7900X processor running at 4 GHz nice and cool at 58 degrees Celsius over ambient. Our results put the Level 20 GT RGB in a tie with Cougar Panzer EVO and barely ahead of the MasterCase H500M. It would seem that the air gaps on both sides of the tempered glass front panel let more than enough air into the chassis, allowing the two 200 mm fans to do their job.


GPU temperatures, tested in both standard and vertical layouts, peaked at 49 degrees Celsius over the ambient room temperature, on par with the other cases we tested against.

As always, we took sound pressure level readings with two off-the-shelf dB meters from two different angles. With the fan speed at default speed (1,000 rpm), our test system registered just 29.1dBA at idle, results that are right in the middle of the cases we used for comparison. With the test system under load, sound output increased to 33.3dBA, again, right in the middle of the pack.

Cooling efficiency and noise levels are both ways to measure performance. Determining acoustic efficiency, also referred to as cooling-to-noise ratio, is a matter of averaging all five of our tests to determine a base value.

Bottom Line

If you’re looking for a purpose-built full-tower ATX chassis that can accommodate an array of different system builds with an emphasis on tempered glass and RGB lighting, Thermaltake’s Level 20 GT RGB might be just what you need. But at $289 (£ 227.13), we’d like to see less plastic and more metal used in the chassis. And the dust filters on the top and front are a pain to remove and clean.

Those looking for a big RGB chassis on a tighter budget can opt for either the Cooler Master MasterCase H500M or the Cougar Panzer EVO RGB and save some money in the process.
