Liquid-cooling specialist Alphacool has announced the launch of a new model of compact pump, the VPP755 Eispump, which it claims improves upon the D5 pump design while retaining full compatibility with existing tops and brackets.
Among the improvements Alphacool claims to have made in the design of the VPP755 Eispump - literally 'ice pump,' a somewhat more prosaic moniker than its previous Eiswolf, Eisbaer, and Eisbrecher ('ice wolf,' 'ice bear,' and 'icebreaker' respectively) - include the ditching of traditional ball bearings in favour of a ceramic shaft and the shifting to external motor coils. Together, the company claims, these contribute to a reduction in noise and vibration levels while also dropping the power consumption of the pump in half to just 14W at the same 4m head pressure as its predecessors.
Other features in Alphacool's Eispump design include a rotary encoder on the rear of the pump for manual control of the speed, which can work in tandem with a 4-pin pulse-width modulation (PWM) connector to set a maximum speed while still allowing for dynamic control via software. For users with no spare 4-pin motherboard connectors, the pump also comes bundled with a 3-pin header from which PWM reading but not control is possible. Power, meanwhile, is provided through a dedicated 4-pin Molex header.
According to Alphacool, the VPP755 Eispump measures 60mm x 53.5mm, comes with a 50cm power cable, and supports a 4m head pressure with a maximum flow rate of 350 litres per hour. The maximum operating system temperature is 65°C, and the five user-adjustable maximum speed limits available through the rotary encoder range from 1,800 to 4,500 revolutions per minute (RPM).
The VPP755 Eispump is available from the official Alphacool store now, priced at €69.95 including VAT but exclusive of shipping.
