PrimoChill Enhanced D5 Liquid Cooling 12V Pump Motor – PWM Enabled – Single Edition

The Enhanced D5 Liquid Cooling 12V Pump Motor – PWM Enabled is the revised version of the popular D5 PWM pump. The Enhanced D5 is still a high reliability, high pressure industrial pump, featuring a 50,000 hour MTBF (5 year lifetime). Such reliability is afforded by the same unique design of the original pump, which contains only one moving part: the magnetically driven spherical impeller spins on a single ceramic bearing, thus extending the life of this pump beyond existing standards.

The enhanced part is packed into the new PWM control chip. With this new controller the D5 now has a duty-cycle, feedback, and PWM control that scales in a similar way as the DDC 3.25. This makes it a very reliable and smooth operating pump. This PWM control allows you to automate the pump speed based on CPU temperature using the motherboard PWM CPU fan header. This functionality keeps your pump only running at speeds that are needed. This also allows the safety feature of auto shut down based on RPM feedback if available in your BIOS.
