6 – Agressive Throttling and Noise

Actually it’s not a suprise. Agressive throttling of the GPU is the only way to keep it in the temperature range. In nearly every test, the GPU temperature reached the maximal value of 93°C. And as soon as the GPU reaches 93°C, the GPU core clock is downclocked by NVIDIA GPU Boost technology.

The following screenshots (FurMark 1.14 is used) shows the GPU throttling in action. I monitored the GPU core clock with MSI Afterburner. The boost clock of the GTX 760 is 967MHz. But as soon as NVIDIA GPU Boost detect an overheating, the core is downclocked at 400MHz or even at 200MHz if necessary.

Okay, you’re telling it’s FurMark and many GeForce cards are more or less down-clocked with it. But in the case of the BRIX GTX 760, every GPU test I ran has caused a throttling:

TessMark (GPU Test 0.7.0)

– Even a simple triangle (GPU Test 0.7.0) caused a GPU throttling!

With most of the 3D applications, the GPU can not work at full speed. The heat produced by the GPU (and certainly combined to the heat produced by the CPU) is not sufficiently dissipated and then the GPU ends up to run at a limited clock speed after a short period.

The two 50mm fans are not enough to evacuate the heat and cool the processors.

What’s more and this can be a problem for many, the fans are noisy. At idle, we can hear them without problem. But quickly after the launch of a 3D app,
you can hear them screaming! Unless you have a headphone, it’s not possible to stay near the BRIX!

The Turbo Mode

You can select this mode in the BIOS. In Turbo Mode, the fans speed is permanently set to the max. The noise is just insupportable. It’s like working close to a vacuum cleaner! But the turbo mode improves things a bit. There is less GPU throttling since there is a better cooling. And when GPU throttling occurs, it takes less time to restore full clock speed since the cooling is more efficient. But the noise…

With the TessMark X16 test, the avergae core clock speed is higher than in regular mode (called Operation Mode in the BIOS) most of the time as you can see on the following picture:

    1344 CUDA cores, 112 TMUs and 24 ROPs it’s desktop 660Ti actually

    6GB VRAM is excellent :O 🙂 but Brix GTX 760 is crap for gaming because it’s much slower than GTX 760 reference. :S lool

    Do you think running the Brix without it’s case on would help the overheating? (when i say case i mean like leaving off the side panel with the ethernet port/HDMI/USB but keeping the top on)

    Nice idea with that Box, but the components aren’t efficient enough for that small box. Its nice to have High-End-Components in such a small case, but if you can’t use it under full utilization, this is senseless.

    Zotac do that better with his ZBox EN760. Yes its not as fast as this box (before the Brix-Box throtteling the GPU), but its quiet, it doesn’t overheat and it doesn’t need to throttle the GPU under long time utilization.

    Perhaps Gigabyte develop a new Box and solving that problems, than its a real nice small PC
