CoolIT ECO A.L.C. CPU Water Cooler ReviewMon, May 03, 2010 - 12:00 AM
First, with the system running at the stock 2.66GHz the ECO A.L.C. cooled our i7-920 to 63.25*C, 10.75 degrees cooler than the stock Intel HSF, 4.5 degrees warmer then the Corsair H50, and 5.25 degrees behind the Noctua NH-U12P single fan configuration.
Now with the system overclocked to 3.5GHz the heat is turned up. At full load the ECO A.L.C. cooled our i7-920 at 73.50*C. Now that is 10*C cooler than the stock Intel HSF and 11.25 degrees warmer than the current $90 air king, the Noctua NH-D14. The Corsair H50 is still holding its 4 degree lead.
Now, the coolers like the Corsair H50 the ECO A.L.C. support dual fans for a push pull scenario. Since I tested the H50 with dual fans I felt I needed to treat the ECO A.L.C. the same. So I fired up the ECO with a pair of NH-U12P 120mm fans. Running the system at 3.5GHz the dual fan configuration helps. The temps dropped 4 degrees to 69.5*C at full load, putting it in line with the performance of the stock Corsair H50. As you can see from the chart, the airflow direction of blowing into the case or exhausting out didn’t make any difference. Running a higher CFM fan could help due to the ECO A.L.C. radiator design, but I can’t test that theory as I don’t have any.
