On a recent day, the Arctic Co. has broadened its CPU coolers range with the Freezer 12 and Freezer 12 CO (CO means “continuous operation”) samples under the ACFRE00027A and ACFRE00030A code names.
The heatsink is the same for both coolers; fans are different, though. The Freezer 12 fan is built on a hydrodynamic bearing, and Freezer 12 CO is based on a fan with a dual ball bearing, which operates extremely long comparing to the better part of models.
The heat dissipator is designed so, that U-shaped 6 mm copper heat pipes stay in touch with each other, thus enhancing the cooling system productivity. The aluminium pressure plate and 45 bent radiator fins also contribute to that.
Fans start to operate at the PWM signal with 40 % pulse width and ensure passive CPU cooling while completing trivial tasks. This lets coolers work silently during such periods. The ultimate noise rate is 22.5 dBA, and the max speed comes up to 2,000 rpm.
Both Arctic novelties support …
