I had already opened RealTemp and seen what it was displaying for the "at idle"Ě temperatures, but I also wanted a second opinion. AIDA64 shows the exact same numbers where the CPU is 57 degrees at rest. You can also see it shows we are pulling 8W currently to power the CPU.
I wanted to really stress the CPU, and I was planning on grabbing a quick image and one with higher temperatures later on to show how long it takes to get that warm. What I found was that the temperature immediately shot to the 67 degrees you see here, and never went any higher.
I also went with GPU-Z to see what the HD4000 was doing inside of the tiny little box, and you can see that even with 25 degree ambient temperatures, the GPU is just slightly cooler than the CPU at 53 degrees at idle just displaying the desktop and these windows.
I ran Unigine to see what the HD4000 is capable of. Without tessellation running I made sure we were on DX11 and let the app run. After a few passes and with 16 FPS maximum, the GPU reached 70 degrees with an average load of only 55% to the GPU. While I am able to play some Valve titles and obviously flash based games, trying to play something like Battlefield 3 on here isn't going to happen.
