Experienced watercooling enthusiasts will know at a glance why there are thick parts on the tubing of the Alphacool Eisbaer Extreme CPU cooler; they are quick release fittings.  This allows you to expand your cooling loop to include a graphics card or a motherboard with integral watercooling or just about anything else you might want.  To ensure it can handle that extra heat the radiator is noticeably larger than your average 280mm rad, at 385.5x156x64mm. 

When testing KitGuru revealed this is a cooler for overclockers, at stock speeds their results show its performance to be in the middle of the pack but once the i7-7700K was overclocked to 5GHz it was unbeatable and still quiet.

"These pre-built, pre-filled units share a lot in common with custom water-cooling loops, primarily in that they can be disassembled or expanded. With the Alphacool Eisbaer Extreme priced at just under £230, is it worth the money?"
