    Can see it didn't change position. Here is my own 2010 build.

    Does that power supply get the fan to move convincingly?

    I notice on the label it is rated for two amps, while the BATT FAN fuse in the car is rated for ten.

    I haven't tested it extensively for a long period yet, but i used 2A because Prolong charger use 1.9A and it works.

    I figured out a sweet hack for bench testing (ok its not really on the bench) the cooling fan. I heat up a small glass of water & dip any one of the three temp sensors into it for about 5-10 seconds. If you have the dr prius app on you can watch the temp rise above 100 if the fan hasnt come on by 100 it aint going to. Every one I tested so far came on strong enough to feel the air blowing up outa the modules. The little fans are very quiet even at full blast. So if yours is noisy there is something wrong with it. I made a video showing how I do my hillbilly fan test on SaneAuto Youtube.
