Preparation is the key of everything ( 85% preparation + 15% work = 100% of wanted result at the end ), so i stripped wire ends and treated them with tin.Įxtension wires connected with the stator wires. Total of 6 coils with 2 wires, so i had to cut 6 exact wire pairs. Stator pulled out from pump's casing, i did this for easier wire preparation. PCB contacts treated with solder for easier soldering of stator and power / control wires. R2 and R3 are locations for those 2 resistors, and D1,D2,D3 & D4 are places where you should solder LEDs if you wish.
Power mac g5 case hackintosh upgrade#
In that upgrade kit i've also received 4 blue LEDs and 2 SMD resistors, but as i don't own transparent top + i hate blue LEDs inside of a computer ( they are too much redneck-ish ) i won't use them.
This is a huge benefit in form of power delivery to the coils itself and it is more prone to pcb burnout due copper current limitation old boards had ( copper lines on the board were too small and too resistant, aka they were limiting max current that can flow into the coils, and when users placed those pumps into restrictive loops, stator demanded more and more current to maintain desired RPMs ) We can clearly see how far technology went in just 10 years, that single IC and a few diodes on new PCB are replacing bunch of ICs and semiconductors from the old PCB.Īlso new PCB is made out of 4 layers, vs 2 layer on old one. New PCB is slightly smaller than original one System was flushed out and disassembled and pump is ready for her upgrade I've ordered PWM Control 18W PCB for DDC pump ( )because there is no need for the pump to run on max rpm 0/24, and i wanted to use benefits of Sabertooth 4-pin headers and ASUS's Thermal radar control. Yesterday i got some presents again, this time from.
