The guide lists the chassis fans as 120 mm, which conflicts with the maker's 140 mm front fans in the launch release.6Press articlecomiccrusaders.com/editorial/tech-news/maingear-unveils-the-all-new-mg-1-a-total-redesign-of-its-most-awarded-gaming-pc-everRead 15 October 2026Release: three 140mm intake fans through a large front panel intake, with a top-mounted 360mm AIO radiator that exhausts. Windows Central confirms the trio of 140mm front fans. Tom's Hardware's open table counts 4x 120 mm case fans in total. The setup guide lists 120 mm intake fans. These conflict. The maker's 140 mm is stored. A possible rear exhaust fan is not stored, because no open source states its position and size. Radiator fans: 3x 120mm RGB for the Epic 360 per the setup guide.
