The Cooler Master Seidon 120M is a mainstream liquid cooling system for processors. It has a 120 mm radiator with one 120 mm fan. Let’s test it.
As with any sealed liquid cooling system, the Seidon 120M comes with the coolant liquid pre-filled inside the loop (block, radiator, pump, and hoses).
Figure 1 shows the box of the Cooler Master Seidon 120M.
Figure 2 shows the contents of the box: the radiator-block set, fan, manual, a small syringe of thermal compound, and installation hardware.
