[QUOTE=Kenshin;2706551]The whole body of 2013 Mac Pro looks similar to Zalman’s Reserator liquid cooler. I had one Reserator. It had no rotating fan, but the massive body helped to maintain temperature on CPU, GPU, and other parts at about the ambient temperature. The large heatsink may not be as powerful as cooling fans of high RPM, but I think it’s far more efficient (especially for those who want smaller form factor and much reduced noise.) Mac Pro has a big fan for extracting the heat collected from the large heatsink. I hope it’s easy to adjust the fan’s RPM.[/QUOTE]
I’ve seen the design and read about the way its theoretically supposed to work. However, they are also claiming to allow workstation performance using up to two pro level video cards and up to 2 xeon 12 core CPU’s if what I have read is true. That’s a lot of heat to dissipate. And the unit is even smaller than the last set of MacPro’s, concentrating all that heat in something as big or a little bit smaller than a bathroom wastebin.
As far as the fan adjustment, I doubt they will make it easy. From past experience, Apple errs on the side of low noise/virtually silent fans with their stock settings. The only way I’ve been able to adjust the fans in my MacPro is to get smcFan control installed and then setup a fan profile. Of course now its noisy, but my CPU core temps went from mid 60’s-70oC down to 37-43oC at 100% load.
