The Arctic Liquid Freezer III 420 A-RGB has a radiator size of 458 mm (length) x 138 mm (width) x 38 mm (height). The Thermaltake View 380 XL TG ARGB case supports graphics cards up to 420 mm in length and CPU coolers up to 160 mm in height, but the case type is a Midi Tower without specified radiator support dimensions in the provided data. Given the radiator length of 458 mm exceeds typical 420 mm radiator slots and the case's maximum GPU length is 420 mm, it is unlikely that the 420 mm radiator of the Arctic Liquid Freezer III 420 A-RGB will fit inside this case without specific radiator mounting support for 420 mm radiators. Therefore, fitting this cooler in the case is probably not feasible based on the radiator size and case specifications.
