Laing DDC pump repair PCB mod

[Martinm210]

Thanks Martin,

Do you know if he plans to integrate that PWM functionality into the PCB boards he's selling in his DIY kits?
I'd personally prefer that much more than some separate, "dongle-like" device.

Even if it tuns out that this is one of the things he's planned...
Decoupling/dampening my MCP35X is going to be trickier than for other MCP35X owners

Mine's built into the side of my Rad! (part of the AIO rad/res/pump known as the MCR220 Drive rev.2)
Then again because of the way it's mounted, it may already be decoupled to some extent?

The cooling heatsink (but no lift?) you linked to earlier may still be possible.
I think the hot end of the pump is exposed to the air, not joined to the rad.

I'm struggling to find/remember what was said, but I did find the old post he noted on the possible PWM functionality of the Toshiba (I have not tested this myself though):

Use motherboard PWM to control the Toshiba PCB modded DDC pump speed seems very simple
Only one resistor and capactior can do the trick!

anybody have time can test and let us know if it work

Not sure I understand the 35X comments, you are not going to remove a perfectly good working 35X board are you? I would not do that, I would only use these replacement boards for burned pumps.

The radiator version shouldn't matter other than you'll have more noise issues to deal with than a stand alone pump since the radiator flavor can't be decoupled the same.
