The new iMac has come a long way from the first 15-inch iMac. Take one look and you’ll see just how far. A 21.5-inch or 27-inch display with edge-to-edge glass covers nearly the entire front of the enclosure. When all you see is the display, nothing gets between you and what’s on-screen. Movies, TV shows, websites, photos — everything looks stunning on the new 16:9 widescreen iMac display.
The wider iMac display allows more room to separate the two hottest components, the CPU and the GPU. This keeps things cool inside the iMac enclosure. Apple engineers also implemented an intelligent control system that monitors temperatures and delivers just the right amount of airflow to critical components. And the three fans inside iMac have been tuned to be ultraquiet. The result of all this tinkering with heat and sound? A system that operates at 18 decibels when idle — so quiet, you hardly know it’s on. |
