Posted November 6, 2016 (edited) Alphacool has just released an improved version of the popular D5 pump. Their old model was called VPP655, so this one is VPP755. The interesting part is that they claim to have redesigned even the internals of the pump, resulting in more power and less noise than the old one. Specificly they give examples of the old model pumping water to 3,7 meters as the new one will do 4,0 meters and it consuming 23W of power for the same water flow that the new one can produce with 14W. VPP755 has a new bearing that should make it more quiet and the pump's speed can be adjusted between 1700 - 4500 rpm. It has molex, 3-pin and 4-pin PWM connectors so that you can run the pump at constant speed but still monitor it through 3-pin fan connector or alternatively control it complitely with 4-pin PWM fan connector. When in PWM mode, you can still change the maximum speed that the pump will run with the switch in the pump. Additionally it looks better now with metal body, sleeved black cables etc. Interestingly the pump is also noticeably shorter, taking a bit less space. UPDATE 1: Oh, I forgot to mention the price. It seems to cost around the same as the old model. On Aquatuning.de the basic VPP655 is 64€ and VPP655 with PWM control is 72€. The new VPP755 fits right between them at 69€. UPDATE 2: Xtremerigs has already a review of the pump. I highly recommend reading it if you're interested but here are the main findings: - VPP755 has a slightly differing dimensions compared to a normal D5 and not all pump tops will fit! - The pump motor has no real PWM control but instead runs on one of five preset speeds depending on the PWM signal. The manual control on the pump uses also those five steps, so no linear control. - The pump actually is more powerful, silent and a lot more energy efficient than a regular D5. - The sleeving on the cable is not the prettiest that there are. But the housing is really nice and more color options of it should be available in the future. UPDATE 3: Taken from Thermalbench's review: Quote Alphacool tells me that they have tested compatibility of the VPP755 with D5 tops from Alphacool, Aquacomputer and Heatkiller. So there is an extrapolation on their part regarding universal compatibility. However, they also mentioned that Xylem/Laing made a small physical change to the D5 itself in 2011- so much so that tops made for the D5 pump prior to this information are not compatible with the VPP755, and barely compatible with newer D5 pumps if at all. As such, Alphacool is saying here that their VPP755 should be compatible with all D5 tops that are new and catering to the physical change in the D5 pump.
