From my experience, yes, but I have only browsed the net and watched videos. Never heard the fan kick in or felt the iris pro only machine get hot.

I'm not even sure the fan is running appreciably on mine when the 750m isn't in use. I haven't spent much time with the Iris Pro only model, but if I can't hear the fan on mine, it's probably comparable.

When the 750m turns on, it does get more noisy, but the 750m only turns on like that if I'm playing a game or something that requires the 750m.

I haven't heard the fans spin up at all and iStat pro indicates that all temps are around 30-35 degrees Celsius whilst browsing the web, reading emails, even youtube. 15" rMBP 2.3GHz i7 with the GT 750m.

I actually have the mbpr 15 2012 at the moment and on some apps and the external monitors you can't disable the dGPU and the fans are very loud

You can use the 2.6 on your lap. You can disable the dGPU when not in use.
