My 2014 i74ghz 1tb ssd 295x imac's fan is kicking in (rather loudly) regularly at various times under medium load, far more than I ever heard the 2012 top end imac's run. It's not the end of the world, but in seems like it is coming on 10x more than the prior imacs. Could it be the 4ghz cpu? Maybe runs hotter,especially when turbo kicks in? Could it be the 295x compared to earlier cooler running graphics? Well in any case it's bothersome.
