(Now I am not versed in super technical things with CPU’s) but, I am needing to plug into a 4 head pin connector and 3 head pin connector, which is usually on a CPU Motherboard.
There is already a relatively high power fan inside the air inlet, you need to ensure what you are making does not restrict the existing airflow. It’s not as powerful (or loud) as the exhaust fan, but it still moves a decent amount of air. Anything you add needs to be at least that same volume or higher.
As to power, you can buy all kinds of power supplies on amazon, ebay, etc., you will just need to ensure your gadget runs on power alone, without a control signal that it would normally expect from a motherboard.
You certainly can’t plug it into the Glowforge. There is no additional power capability for accessories.
Yes, the last thing I want to do is block another fan.
I have been seeing videos where people take an old barrel outlet plug, splice the wires and connect that way, but if possible, I’d like to just buy the 3 and 4 pin pronged that goes directly into the wall outlet, if that may be a thing?
I don’t really know what to search to find it.
(You know those late night purchases after a drink or two and you don’t think it all through?)
Yeah…that was this, in regards to the power
The 4 pin runs the fan, this would be +12V, Tach, Gnd, PWM (Not in that order going from memory), where is the 3 pin wire is for the pump and that is the same without the PWM. You could wire it to a 12V power supply to run without a computer but you would need to wire up a simple circuit to control the PWM signal to the main fans and just ignore the Tach lines.
I mean it looks maybe ok? I can’t say for sure, I’ve never tried it. You might want to check your fans and pump and see how much power they require (if you don’t get wattage then amps will work here, it’s a good substitute for power when the voltage is constant like this).
If it provides enough power for the fans and the pump then maybe it’s worth a shot? Can always return it and as long as you don’t provide too many bolts you’re not likely to kill it.
You’ll want to verify your pin configuration on the fan and pump and be sure you’re not reversing the polarity, but other than that if it is the correct voltage and power Id probably give it a shot, myself.
