I just bought a Koolance RP-452X2 Dual 5.25in Reservoir Rev1.2 and will need to get 2 D5 pumps to run it, but the problem is there are so many types of D5 on the market and i know they are all based on the Liang series pumps but i was just wondering if those pumps i've short listed below is worthy to buy as Swiftech now offers PWM mode and Aquacomputer offers RPM signal and its made in Europe instead of China, the XSPC should just be the normal rebadge unit of the Liang pump.
Aquacomputer D5 Pump Mechanics with RPM Signal
*** NEW *** Swiftech MCP655-PWM 12v Water Pump Module - PWM Enabled (Single Version)
*** NEW *** XSPC D5 Vario Pump - Without Cover
I was thinking of getting those units without speed control as i dont have any intention to run it on any lower speed other than at level 5
Thanks in advance
