CoolIT Systems ECO A.L.C. 240 CPU Cooler Review

Temperature Testing Results

With the system running at the stock 2.8GHz the ECO ALC 240 did very well, right on the heels of the Super Mega. Coming in at 55*C it beat out its sibling the Vantage by 5.57 degrees, and the Corsair H70 by a slim 1.75 degrees.

With the system mildly overclocked to 3.5GHz the ECO ALC 240 slips back in the pack but is still only 3 degrees behind the Super Mega. This time the ECO 240 and the H70 seem a little more evenly matched with the H70 ahead by a very small 1/4 degree.

Pushing the system to 4.0GHz the heat goes up and the ECO ALC 240 drops in the pack. Coming in at 74.75*C it’s 5.25 degrees behind the Super Mega, 2.25 degrees behind the H70, and ahead of the Vantage ALC by 2 degrees.

Now I wondered what would happen if the radiator had no restriction from the case. Seeing how half of one of the fans was block it only seemed fair to pull it out of the case to see how it would do. With the radiator out of the case and sitting on the desk I ran the tests again with the CPU at the stock 2.8GHz and 4.0GHz to see if there was any difference.

Moving from internal mounting where some of the fan was blocked to sitting in open air made quite a difference. There was a 1.5*C at 2.8GHz and an 8.5* difference at 4.0GHz. So this just shows that the case you use and how it’s mounted will greatly affect performance.

I then slapped four Scythe 68CFM fans I had on the radiator to see how it would perform. At 4.0GHz there was a 4 degree improvement in the performance when mounted internally, and only 1/2 degree improvement externally. With the quad fans mounted internally the 70.75*C temp is only 1.25*C behind the Super Mega on the high pressure setting. At the lower 2.8GHz the gap was a little narrower, but it was still improvement over the stock fans.
