so my sms twin 4.5amp controller has stopped controlling, which lead my to open my boxed fan up i got used as a 5" to find out its some unkown brand 4" lol great i got it to replace a 4" ruck 100L i was using back then
so now i am left with those 2 4inchers and a vents tt ive used as a intake fan
what i want to do is grab a systemair stl 1.5 or 3 amp transformer based controller in a week or so, but i am unsure about running 2 fans off 1 do they have to be same brand and range ? And could i say run a 4" intake and a 6" out , of the same brand like the radair for example ?
the unkown fan in the box
thanks for any info on this macha
