Alphacool Eisbaer Pro ES 2U Quad HPE CPU Liquid Cooler Review

Temperatures

At 87, the Eisbaer Pro certainly isn’t the coolest we’ve tested, although it did give me our lowest idle settings. However, that’s likely due to the fact the fans are going hell for leather at idle, while most other coolers go into a more silent mode.

Using my overclocked settings and optimised voltages soon turned the tide. This put the cooler isn’t its more performance mode, the pumps really going, the fans are ramped up, and the temperatures plummeted; 71c is extremely impressive.

Acoustics

The downside for all that cooling performance, despite its unique form factor, is noise. Those 80mm fans go at 6000 RPM and well, they sound like a server.

Their only saving grace, acoustically, is that the noise is consistent. 68 dBa is pretty freaking noticeable though, that’s for sure as it’s about on par with a noisy vacuum cleaner or loud conversation.

CineBench R23

The Cinebench scores are good though, clocking in 26440 at stock settings, which is certainly on the higher end of the scale here.

And overclocking pushed that to a very impressive 27587 points!

Improvement

So while the cooler maintained its 68 dBa acoustic levels, overclocking and optimisation saw CPU temperatures drop 16c and the Cinebench score increased by 1147 points.
