Hi guys, I have a redragon sideswipe casing with 3 120mm fans in the front ( included ) and one 120 mm fan at the back ( included ). The gpu temperature reaches around 80-81 C while gaming and while its not a big deal, i still want to lower it. There is space for 3 120mm fans at the power box so my question is that will placing fans at these empty spots help in cooling and maintaining low temperatures ? If so, then how much lower will the temperatures be ? The pc doesnt have a great airflow . I have an rtx 2080 and core i7 8700 ( liquid cooled ). Any help will be much appreciated . Thank you ).
