Thinking about modding my cooling pad..
So I got this awesome Thermaltake Massive 23 LX cooling pad, right?
However, I'm disappointed in one aspect: there's no low/hi fan speed option. 230mm fan, and only one speed option.
So, I'm thinking about modding it to have a low/hi switch. However, that would probably mean a new motor that can handle the power differences. The low option would probably run 5V and the high option would probably run 12V, to get some insane cooling when I really need it.
Here's a brief spec overview of the pad's power and cooling.
The motor that's in it is rated at 5V. I'm just hoping I could possibly rig something up. If it involved external AC power it might actually wind up an easier project than attempting to maintain USB power.
Anyway, does anyone here know how I would rig up a switch to flip between voltage levels? I'm not quite sure how I would do it, and would love some assistance. One person said to simply build my own and I will look into that as well, but if I can simply gut this one out and build a new one inside of it using the same sized fan, that would be ideal.Fan Dimension 200 x 200 x 20 mm
Fan Speed 600 ± 10% RPM
Max. Air Flow 54.6 CFM
Max. Air Pressure 0.32 mmH2O
Power Connector USB
Rated Voltage 5 V
Started Voltage 3.5 V
Rated Current 0.21 A
UPDATE: I found a diagram on OverClockers forums showing me how to wire up the switch.. now I'm not sure how I'd get it all to work on external AC power (I would want to go for that). I would need a way to rig an adapter, or find an adapter. Suggestions?
