Hi, GT1850 as you say 0.083 Amps, so at max RPM just less than 1 watt (12V x 0.083A). So 6 watt per port, channel/ Fan Connector ? Should be well enough.
If you want the 2 Fans to run at same speed, not sure how your controller would/ can do it. But you could get a splitter & run them off same connector/ channel.
Whether 2, 3 or 4 pin connectors, normally you can't connect them up wrongly (connectors have positioning guides, well those i have seen use). 2pin just power, 3pin power plus speed monitoring, 4pin power speed monitoring & PWM control. GT's are 3 pin (so no PWM control ie say/ call it auto control from say mobo), will connect to 2, 3 or 4 pin connector from controller etc.
GT 1850 is very quiet, but not at 1850rpm (neither are GT 1450rpm at max, i can get these to start up at 3.1v, 200rpm), i find GT 1850rpm will start up at 3.3 to 3.4volts, around 450rpm (thats what my Lampton FC5 v2 says/ does, not precise readings fluctuates a bit).
Very nice Fans. Being Ball Bearings, very nice horizontal or vertical.
Regards temp, use SW monitoring, RealTemp, Speed Fan etc etc, & keep CPU to recommended Temp or whatever you want/ like.
Cheers BOB
