I've had my Aurora R5 for a little over a year now. About a week or two ago the fan started kicking up very loudly. It'll be normal and then every ten or twenty minutes will get very loud out of nowhere. The noise will last anywhere from ten seconds to a few minutes. This happens even when I'm not doing anything on the computer, it sounds like something is causing it to kick on in the background. It's driving me crazy and I can't seem to find the cause.
I opened it up and made sure to clean out any dust, I did virus scans, I updated all the drivers and BIOS, nothing seems to actually solve the problem. My first virus scan did pick up two trojans, but I've scanned it several times with multiple different programs since then and nothing has been picked up. I can't even tell if this is a software issue or a hardware issue and I'm two steps away from just wiping the whole computer and doing a fresh Windows 10 install, but I figured I'd ask here if there was any way to really track down what the issue might be before I jump the gun and do something that wouldn't fix it anyway.
You can try a clean boot.
Also, check temps to see if the system is not overheating.

Microsoft says that once a computer has been violated and the Windows OS is compromised, the only way to insure it is completely clean is the "Nuke-and-Pave" it.
The ePSA Diags should be able to detect MOST (95%) of any hardware failures. Once you are sure (as you can be) Hardware is good, you move onto Software. Follow this:
Aurora r5 user here too. I noticed this same problem starting last week. I've ran all the same scans & updates etc. and haven't found any issues. Usually goes away after a reboot...
It's definitely the fan that's connected to the cpu heatsink. Been running monitoring software and the cpu hasn't ever been running too hot.
I'm wondering if it's something to do with all the windows updates being pushed out to fix the skylake chipset issues? Otherwise, could be a BIOS issue (which I've tried resetting to defaults, doesn't help anything).
If you've updated to bios 1.0.16, check your temps. I had an issue with cpu overheating after flashing to that bios last week. I have since went back to bios 1.0.14 and the issue has gone away. I am currently waiting for a fix from Dell. Check your bios version and temps of your hardware.
