Unsurprisingly this setup cools amazingly well. I had a 20°C drop over air cooling on full load (going from around 82°C to 62°C and would recommend this GPU AIO for anybody wanting simple cooling solution without going through the aggravation of a full custom loop. Overall I think this is a kickass, inexpensive (relative) way of cooling your card.

With the Alphacool Eiswand, you get a custom watercooling kit with no case fitment dependencies. Setup is incredibly easy compared to most watercooling kits and, to me, bridges the gap between full custom watercooling and an AIO unit for many users.

We have a good feeling that our Foundation waterblock from Optimus will be retiring, and that from now on the high-performance Alphacool Core 1 will be powering our test setup with the Intel i9-13900KS processor and the ROG Z790 APEX.

In Cinebench R23, we see a temperature difference of up to 5 degrees less on the hottest core, and even up to 10 degrees less in OCCT after five consecutive runs.

Looking at the new water blocks, we can already tell that the simple, but eye-catching design is far different from previous Alphacool products.
