|From the cooling
point of view, the Thermaltake Core V21 provides plenty, as well as
various, options for cooling. The bundle only includes a singel 200mm fan (TT-2030, 800rpm and 123.6CFM) with 3-pin header. Overall, the case is able to accommodate up to a maximum of four 120 mm fans at the top and two fans on each side. Bear in mind that the top and the front fan mounts also support 140mm fans.
Since this model is practically designed for an LCS setup, it is quite important
to note that it supports up to four 240 millimeter radiators.
