Alphacool Eisbaer 240mm AIO Liquid CPU Cooler Review

Eisbaer Benchmarking

In the benchmarks that will be run, we used an Intel 4770k clocked at 3.5GHz with Turbo Boost and the low power state enabled.  Turbo Boost allows the 4770k to hit up to 3.9GHz right out of the box.

To record temperatures, we used Core Temp, logged the temperatures for 15 minutes or while each program was active, and averaged all 4 cores.

Slimming down on the benchmarks from previous reviews, we’ll be strictly using Prime95 to stress the CPU and no games.  This will peg all four cores and eight threads to 100% with the In-Place Large FFT test, which will help us to understand exactly how hot this CPU can get with each cooler.  This will allow you to judge if the extreme punishment from Prime95 will be sufficient for your gaming or encoding needs, as you will never see above these load numbers.

Ambient temperature during all testing was 74 degrees Fahrenheit.

I have reviewed several other air and liquid CPU coolers in the past and you will find them in the charts below for comparison purposes.  I have also included the results for Prime95 with the CPU overclocked to 4.3 GHz on this page.

Idle

Alphacool Eisbaer - Idle

 

Prime95 (3.9 GHz)

Alphacool Eisbaer - Prime95 - Stock

 

Prime95 (4.3 GHz)

 Alphacool Eisbaer - Prime95 - Overclocked

 

Overall Results:  Comparing the Eisbaer to the other coolers, I found that this cooler almost worked its way to the top of every chart!  It was only 0.3* Celsius from matching the top cooler on Prime95 OC’d testing.
