TTIC will start 2008 with new VGA Cooler
In 2008 TTIC (nPowertek), known for their heat column technology, will introduce a VGA cooler integrating their cooling tech. It was quite a challenge to get the product to be compact and still carry the advantages of the heat column, but it seems like they pulled it off.
The TTIC GAT-300 will fit 8600 and 8800 NVIDIA cards:
Here you can see the heat column in the middle:
TTIC send along some early test data with a simulated heat source to see how their unit did, they express their results in °C/W; amount of the °C increase per Watt; the lower the number, the better.
They run their tests inside a 50°C chamber and compare it to the Zalman VF-900; their units were build with Copper and Aluminum Copper; here are their results:
It's worth nothing that the GAT-300 fan is running ~300rpm faster than the Zalman unit. Nevertheless, only by looking at the TTIC results, the most interesting data can be seen; as the load increases, so does the cooling capacity of the GAT-300. The Zalman unit gets hotter as the load increases, the GAT-300CU (and AlCu) get cooler.
GAT-300CU: (60 x 0.465) + 25 = 52.9°CHopefully at the start of the New Year, we'll be able to verify these quite promising test results
We received a new data chart with the GAT-300 running at lower fan speed, -330rpm here are the temp results:
GAT-300CU 60W: ~54.8°C (+2°C)
GAT-300CU 100W: ~74.2°C (+4°C)
It's clear that the GAT does benefit from higher airflow, especially at higher heat output, but even with fanspeed below that of the Zalman VF900, the load temperatures remain considerably lower!
