The 160mm tall Thermolab BARAM heatsink accomodates up to two 120mm fans, but is sold without any. Drop in a 120mm low noise fan of your choosing, or perhaps a 120mm unit with a little power behind its impellers. For official test results, Frostytech will rely on the 1500RPM 120mm Mechatronics G1225S12B fan we've been using on other fanless heatsinks to cross our test bench.
