23% CPU usage is high for idle, especially at the boosted CPU frequency of 4.42 Ghz. The base for that CPU is 3.7 Ghz. There's something running in the back ground eating up CPU resources, possibly keeping the CPU boosted at 4.4 or higher Ghz. Whatever is running is also cyclic, as you see the cycle perfectly in that CPU graph. I would go to the processes tab, and click on the CPU % column to sort by highest CPU usage at the top. Then watch to see what's running eating up 23% of CPU cycles. Likely it's a service or possibly a program.   Running on air cooling with that frequency and load is going to give you those temperatures. In my opinion these systems should only be sold with liquid cooling. I don't think the air cooling solutions in these systems works well. You could also try to increase your CPU fan to let's say 80% using AWCC, that should make some difference. You could also switch to the performance profile.  
Hello.  I recently bought an Alienware Aurora R10 air cooled, and it is very noisy.  The temperatures seem high when not really doing anything.  Right now, I have had Windows 10 up and running for 30 minutes (to verify it's not just due to startup processes), and my CPU is hovering between 80-85 C while running only 2 apps: Even if I shut both of these down, I can still hear the fans running high.  Here are screen shots of my CPU Temps and of Windows Task Manager.  The system doesn't look to be "taxed" in terms of resources.  CPU, Memory, Disk look fine.   Does anyone have any idea why it's running so hot?  I also haven't been doing any gaming today, this is just boot up, let it sit about 30 minutes while only using a Web Browser.   The fans and CPU are the OEM ones it came with.  Thanks very much in advance! [IMAGE]Alienware CC[IMAGE]Task Manager
