So i bought a Alienware Aurora R6 less then a year old. But sometimes when i turn it on it says CPU Fan Failure all of a Sudden. Now its not every time i turn it on, Just sometimes. Computer is still maintaining temp in the 30-37 degree celisus range even when i had a game running it jumps sometimes to the mid 40s. Only fan i notice not running is the power supply fan



My specs for the computer are
Windows 10
NVIDIA GeForce GTX 1070 8GB dedicated graphics
Technical details: 7th Gen Intel® Core™ i7 processor; 16GB memory; 256GB solid-state drive; 1TB hard drive
Special features: AlienFX lighting; built-in wireless networking

You could try a different fan if you have one. Could also be an issue with the header.

Maybe a BIOS flash would help failing simpler explanations?

Basically, that warning means that (at least sometimes) the motherboard doesn't see the fan or thinks it is broken

PSU's fan are smart these days and only turns at a specific temps. You shouldn't worry about PSU.
The CPU fan can sometimes be connected to a normal fan header instead of a cpu fan header which can explain the failure message sometimes. I doubt it is a bios issue, but you can definitely reset the bios. Or to be 100 percent sure, you can open your case and see where the cpu fan is connected to. If the Cpu fan header on the motherboard isn't being used, you can simply switch the placement for your fan header and it should resolve the problem, and while doing that, you can as well boot when the case open to check if the cpu fan is being turned on when booting.

This

Depending on the BIOS, some will not even POST if there is no fan detected on the CPU fan header. Could be that it is on the wrong header or that the header itself or the fan failed somehow (unlikely)

it is really hard to say unless you check for yourself and open the case and see it with naked eye

CPU fan is being turned on when turning CPU on. Also it is connected to header on motherboard

As long as your temps are good it should be fine.
