MCP35x Pump Connection? - Page 3

post #21 of 40
Yellow wire is 12V get this from molex period
Black wire is ground get this from molex period
Green wire is PWM control wire, get this from a 4 pin MB fan header
Blue wire is the RPM sensor wire, could be connected to any fan header.

If you plug the stock setup into a 3 pin fan header, it would provide you RPM monitoring, but not PWM control.

Update:
Disregard the splicing of the PWM wire, this document seems to indicate you can't or shouldn't do that either.

You also need a program like Easy Tune from Gigabyte to precisely tweak the PWM settings and that may only be possible with some of the newer MB. Old boards like mine don't have the flexibility to dial in a percentage, but my son's newer Gigabyte board can control from about 20-80% or so.

Aye, thanks.

So essentially I'm thinking I should just not plug them in and run them both at 100%. Seems to be the most logical at this point.

Yeah, try that first and if pump noise becomes a concern, then you have the option to either turn it down via PWM, or through a voltage controller capable of feeding the pump. The pump can actually draw about 30 watts at total free flow, so it would have to be a good fan controller.

No need to mess with any of that though unless it's simply too noisy for your tastes. Just plug in the molex connector and go..

Can someone confirm mcp35x connection to PWM motherboard header bearing in mind that "The fan connectors support cooling fans of 350mA ~ 2000mA (24W max) or a total of 1 A ~ 3.48 A (41.76 W max.) at +12V." (from mobo manual.)?

MCP35X draws it's power from a Molex connector, it only takes PWM speed signal from motherboard's cpu header.

have you ever though of powering the pump via CPU header, since the last can handle upto 24watts?

I guess you could do that but then you'd have to cut off that Molex connector and connect those leads to cpu fan header connector. Seems like like a lot of work for nothing.

not, if you have a proper adapter.

Yes, but I still don't understand what you gain by doing that, your PSU has no spare Molex connectors ?
