Ye, that's the next option, but i will try to figure out, just for a cleaner job. I really had high hopes you would know.
Anyway im planning to use 2xsw3 pwm non high-speed. They're power consumption is around 0.12A, so there's that...
Question 1: if i buy sw3 high speed and run them at the same speed as the non high speed, the power consumption should be around the same right? I don't plan to run them any higher than 1200-1300rpm (it's lower than both max cus one it's 1450 and the other 2200), but i thought that having so much headroom and despite being the same fan, might be a bit more silent or have higher longevity.
Question 2: im watching at the graphs in technical data for the sw3 120mm high speed. The fan at max is 2200 RPM, but it shows it can start at around 200+. It's that bull****, or it's actually possible?
Offtopic: By the way im looking at nf a14 and sw3 140mm high-speed and the nf a14 is 0.13A and the sw3 0.5A. Why so much difference?? I thought they should be closer to each other.......much closer.
As always, tnx for the help.
