  • 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.
