I have a single radiator for cooling, and i was running it with one fan in front, one behind push/pull etc, however, i have spare fans and rigged one onto the radiator so now it has two on the front and one on the back, im also thinking of adding a fourth to the back so its 2x2 in push pull, haha, two on the front and two on the back. Is this crazy? What im concerned with is that if some fans rpm is different, could it cause some to burn out due to the different speeds rotating at? Like a backpressure scenario, with one fan forcing the next one to under or over rotate thus creating friction or irregular voltage /heat in the fan motors? pic below,note two fans in front,one rear, thoughts on this from tpu technocrati ?
