I do have 3 x SiPolar hubs that can't seem to handle even 2 Compac F's above 2.5A so I am happy to replace hopefully all of them!
Im not sure what you mean but i use 5x sipolars 120w hubs,all populated same way with 3Fs & a fan on each hub and all running btween 525Mhz to 600Mhz. that i believe is a power range of 2.7A to 3.3A. I havent perfected the art of tunning them all to run at same freq so i left them to run that way for now..
My observation is.. Even Sipolar has a fake.. while i was shopping for sipolar hub i noticed the fake one from the real , they called it Sip0lar - where the o was replaced with numeric zero -0. so i went straight to the source to order , which means goin back all d way to china.
Unless my results below doesnt count .. I stand corrected.
