Unfortionately, this new antec tricool 120mm 3way fan that I ordered does not have indentations in the side for the latches on the lower chamber to fit into, like the tricool fan that came with the p180 had! What am I going to do? It wont fit there... Maybe I could tape it? But I dont wanna do that! Is there a place that sells lower chamber replacement fans, since it evidently is not a normal antec tricool 120mm? Help someone!
