TDP for a i7-5930K is 140w and the cooler specs say it allows users to push any LGA2011 processor to 140W or beyond...I'm a bit confused why you didn't test out all the modes for this since it appears to compare with other big air coolers and even some AIO coolers
TweakTown did a much more thorough review of this product and in insane mode it competed with a H100i GTX. The selling point here really seems to be the performance you're getting in the size.
