Stock






Temperatures at stock speed are relatively low using the stock configuration. While it doesn't match up to the bigger, more efficient air coolers, it still manages to significantly reduce the temperature compared to the old Domino A.L.C. The ECO is also better than the popular Noctua NH-U12P and the more compact NH-C12P SE14. Idle temperatures are also impressive, even besting the Prolimatech Megahalem with 2 fans. Once another fan is attached to the ECO, performance takes a turn for the better. Using to Noctua fans reduces noise levels dramatically and provides cooler operation. For all out brute cooling, attaching a second CoolIT fan or 2 Coolink fans makes the ECO one of the best solutions at the expense of noise.

*Update*

Following requests to testing the CoolIT ECO with the fans in an intake configuration, I conducted a few more tests. Having the fan as intakes certainly made a big improvement to temperatures at stock speed. Using two Coolink fans as intakes improved temperatures by 3.25 degrees and similar using one single fan, the temperatures drops by 2.75 degrees. This puts the ECO in the same realms as the better air cooling solutions.
