Temperatures

All temperature charts are sorted with lowest load temperatures at the top.

As you can see, performance from the Eisbaer is certainly very good. At stock clocks, it is joint second for cooling performance. When the CPU is overclocked, it shares third place in our chart with the Thermaltake Water 3.0 240 RGB.

It is not the chart-topping performance of the Arctic Liquid Freezer 240, but no other cooler I have tested so far has the ability to expand beyond just cooling the CPU. As such, it looks like an enticing proposition.

Noise output

The included Eiswind fans can spin at just 550rpm, which is rather slow – and as such, the Eisbaer is very quiet when idling. Matters are also helped by the pump – it is also very quiet, with no noticeable hum or whirr. The pump can also be run at 12V or 7V – so if you do not mind sacrificing some flow pressure, pump noise can be all but eliminated.

Under 100% load, the fans kick up to 1700rpm – which, compared to some fans I have used previously, is relatively inoffensive to the ears. They are of course audible, but the noise is a low thrum, rather than a whine, which makes the sound much more bearable.

However, I cannot comment on the noise produced with two components in the loop. The relatively thin 30mm radiator could cause the fans to go full pelt constantly, at which point a push/pull configuration may help.
