Performance and Comparisons
With the Intel Core i9-9900K configured at 3.6Ghz core frequency, the Alphacool Eisbaer Aurora recorded 32.2°C average delta CPU temperature under load, which is a little below the thermal performance what we would expect from an all-in-one liquid cooler of its size.
In our initial overclocked test, with the CPU frequency set at 4.7GHz, the Eisbaer Aurora 360 recorded 50.5ºC average delta CPU temperature under 100% load. Again this is higher than we expected and it is being outperformed by other AIO coolers of its type.
It's much of the same story with the Intel Core i9-9900K core frequency at 4.9GHz. In our extreme overclocked frequency test, the Alphacool Eisbaer Aurora 360's thermal performance is slightly disappointing as it is beaten by cheaper air coolers and many other AIO coolers that we have tested over the past year.
Maximum speed of the Eisbear Aurora fans is relatively high at 1800RPM. However, noise levels are more than tolerable, we recorded a maximum 46.1dbA noise with the fans running at full speed, which is considerably lower than some other all-in-one coolers we have had on our test bench in the past.
