TTIC will start 2008 with new VGA Cooler 5 Attachment(s) 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. From OC.com Quote:
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 :) ================================================== ============================================== UPDATE! ================================================== ============================================== 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! |
^Update with the load test results, running at lower fan speed! |
