I wouldn't say it's insufficient. In the video he never raised the temp limit to 90°, which is the first thing pretty much everyone would do. I could also do my OC with fan at 60%, which isn't very loud in a good case, and have pretty much same numbers. I think I lost maybe 25mhz on clock vs fan at 90%. Temps were just higher. I didn't log that number but I want to say 86/87°. So all in all it got job done fine without much noise, as I turned fan to 90% purely for numerical reason, or performance loss. I definitely cannot argue against anyone passing this thing up but it is an absolute beast. Spend an additional $400 (shouldn't have to at that price, right) and you've got yourself an amazing AIO w/360 radiator, cpu block and prefilled full gpu block to put out jaw dropping performances....and you don't have to wait ;-)
