Chad's CPU Cooler Test System Specifications




To see our testing methodology and to find out what goes into making our charts, please refer to our CPU Cooler Testing and Methodology article (October 2016) for more information.



Thermal Results




Right out of the gate, the Eiswand performs admirably at stock, with 12V supplied to the cooler. 53.25 degrees is nothing to sneeze at, but once we added in the 7.5V adapter, the story changed. Using it, reduced efficiency, of this massive tower three degrees. On average, the results are good, but this is four to five times the expense of coolers around it.




While not the same thing as allowing for PWM control, when it comes to the overclocked runs, it seemed fair to break the results down to similar fan controls on other coolers. Using the 7.5V adapter for this result, we see that the Eiswand comes in at 72.75 degrees. Right in the middle of the chart, which isn't bad, but for the cost, we feel this should be topping the charts.




Allowing the Eiswand to run with everything the PSU can supply on the 12V line, results do not fare much better for Alphacool. While 70.75 degrees is only four degrees from the lead, we feel that this should have lead the pack, and are saddened that it does not do exactly that.



Noise Level Results




When using the 7.5V adapter for any of the testing, we took a measurement of 34 dB, coming from the back of the tower. We did have to add a wire to sense the RPM, as nothing reads it built into the Eiswand, the fans were turning at just 625 RPM at this time.




While we did see 890 RPM with our ghetto mod to the tower, the noise increased to 48 dB. We do realize that if the intent it to break records, sometimes you have to give a little to gain a little. However, we did not gain much performance to account for the extra noise.
