Alphacool Eisbaer 360 AIO Modular CPU Cooler Review

Performance

Temperatures

The Alphacool Eisbaer is the most extreme cooler we’ve ever tested. Of course, it’s a custom loop cooler in a pre-built form factor, so it’s setup to perform better than anything we’ve tested to date. It makes no excuses when it comes to cooling our 7700K, topping out at just 51c under full load. Obviously, that’s miles ahead of anything else on our charts. Overclocking the CPU barely made an impact on the heat either, with incredible idle and gaming temperatures, and just 58c under full load.

Acoustics

Of course, the acoustics are exceptional too. It hovered between 33 and 34 dBa from idle to load. Furthermore, the only thing quieter at idle is the Noctua NH-D15S. However, at load, it’s right up there as the best. Amazingly, overclocking only pushed up the acoustics by 1dBa, and without a decibel meter, you wouldn’t have known it.
