Alphacool Eispumpe VPP755 Revealed
Alphacool is announcing the next evolution in pump technology with the Alphacool VPP755 Eispump. This pump, technologically a completely new development, throws out all the old problems with the well-known D5 pumps and retains only the compatibility to all current D5 tops and brackets. The VPP755 Eispump dispenses with the spherical bearing and opts instead for a ceramic shaft that makes for quieter operation. The motor’s coils are now on the outside instead of inside. All of this provides more stability, which results in less vibration. It also means the power consumption is cut nearly in half. Yet the VPP755 Eispump still boasts a 4m maximum head for higher performance. The VPP755 Eispump is also distinctly quieter than the classic, well-known D5 pump while providing the same performance.
One of the innovations of the Alphacool VPP755 Eispump is its many control options. The 4-pin molex connection provides the power, and plugs directly into the power supply. If desired, the 3-pin connection can be used to read the pump’s RPM. This can be connected to the corresponding motherboard or to a fan controller. Through the 4-pin PWM connection, the pump can be controlled by PWM as usual. The RPM can be read through the 4-pin PWM connection as well.
On the backside of the pump there is a small rotary switch, the same as on the Alphacool VPP755 Eispump Solo. This switch has 5 levels for manually controlling the pump. The unique thing here is that the manual control and PWM control can now work together – a system patented by Alphacool. Using the rotary switch, the general maximum RPM for the pump can be set, which then cannot be exceeded by the PWM control. Practically, this means that if the pump is set to level 3 with a maximum RPM of 3200, you can also only reach a maximum RPM of 3200 through the PWM control.
Now every user can set exactly how the pump should run, and in what RPM range, even if the PWM control on the motherboard or fan controller has few settings.
Visually, some changes have also been made. The Alphacool VPP755 Eispump is about a centimetre shorter than the classic D5 pump and has an aluminium cap. The pump looks elegant and fits perfectly into a modern system.
The Alphacool VPP755 Eispump is an improvement over the classic D5 pump VPP655 in every respect. In no area is it weaker or louder than its predecessor, and it offers new options for controlling the pump according to your wishes.
