Here's what TechRepublic has to say (which is very true):

As impressive as the performance of iMac Pro looks, the price could make it impractical for many professionals and businesses. Having seen past iMacs overheat, professionals will also continue to be concerned about the cooling of the iMac Pro despite Apple's WWDC assurances. In the end, a high-powered Mac tower would have likely cost less, been more modular, and attracted a lot more enterprise buyers.

I maintain an office full of iMacs and other Macs, and have done so for over 15 years. We have NEVER had an iMac "overheat." Not once. . . and some of the applications are very processor intense. Sorry. That is pure FUD. The heat management and fan design in iMacs is very well engineered. What people were complaining about was a stuck software control that caused the fans to blow continually, not an overheat situation. It was fixed by using a keyboard command resetting the System Management Control (SMC). As for a Mac tower, a Mac Pro update is still in the works.
