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.
I bought an Eisbear Solo to build a custom loop for my son’s pc, adding a 360 Alphacool rad and his watercooled videocard. It works, however I question the pumps power in getting fluid around an expanded loop. I don’t think that it is powerful enough to push water effectively through multiple waterbloocks and rads. Not to be used on an overclocked system if adding extra rads and blocks. Installing this block was torment, it is not really user friendly. I could have done with an extra hand and bleeding the system was painful. Having said all of this, in my son’s loop Intel Core i5 and 980Ti (both stock) and a single slim 360 rad performance has been decent. The pump is quiet and has been able to keep the 980ti and Core i5 cooler than traditional aircooling.
if I ever go with water cooling, I will be going with this system
not to post again on the same article, looks like the first AM4 product is now coming to market https://www.techpowerup.com/reviews/MSI/Core_Frozr_L/
