CPU Fan Error?

[Itsyaboi]

I'm hard crashing in all of my games, and I get a "CPU Fan Error" when I boot up my PC. In Bios it shows my CPU fan fluctuating from anywhere to 100-300 or so RPM in bright red, then it changes to "N/A" after a few seconds.
I have no idea whats going on here. What I do know is my computer is shutting off because my CPU is reaching it's maximum heat threshold. But how that's happening is confusing me.
I used to have an R9 390 which made nearly my entire case hot to the touch, maybe even hot enough to cook food on, I'm talking 90c sometimes. And my CPU never had any issues, even with that card running hotter than the surface of the sun.
Now I have a GTX 980ti which runs 20c cooler and quieter at all times and performs beautifully. But my CPU is overheating? My computer is cooler than its been in almost a year.
I have a stock AMD FX 8320 and a Hyper 212 Evo. Yes, it's running at stock with an aftermarket cooler and still overheats. When I installed my 980ti a couple days ago the only thing I did was remove my 390 drivers with DDU and install my 980ti along with its drivers. Didn't touch anything else.
I can't play a single game I own right now, even Overwatch running on Low hard crashes after a game or two.
Not being able to play with my new GPU really sucks, all help is greatly appreciated.

The cpu and gpu are different from one another. You said you're crashing, likely thermal throttling and getting a cpu fan error which sounds like your cpu fan gave out and it's causing your cpu to overheat and your system to crash. Makes perfect sense.

You should remove the side panel off your case and see if your cpu fan is spinning at all or if it's spinning very slowly. If the fan died you need a new one. You should try using a program like amd overdrive to monitor your cpu temps, it should report how many degrees until you reach throttle temp. If it's getting close to 0 then that's your issue.

I know the CPU and GPU are different, I only mentioned my GPU because it was obnoxiously hot and effected every other part in my PC. I already had my side panel off to help with airflow, yeah the fan is spinning extremely slow. I checked AMD overdrive as well and the amount of degrees before throttle temp is at 20 while idle and around 2 when gaming. I'll be buying another fan thanks for the suggestion!

If you power everything down you can gently 'flick' the cpu fan and feel it. Meaning if you hold your finger to one of the fan blades and give it a spin the fan should spin free several revolutions. If it only spins once or twice and stops it's a good sign the bearing is going out in it. Also if you spin it with the system off, if you touch the fan housing with your other hand you might be able to feel if there's any vibration or not. A good working fan should be smooth, a bad bearing will cause a slight vibration.

If it makes you feel any better I literally just had this same issue today on one of my pc's. A high pitched alarm that the cpu fan wasn't operating, opened it up to find the fan on my 212 evo died.

If you haven't replaced the fan on it before, the brackets with the small tabs that hook to the cooling fins are held onto the fan via screws. Once you gently pry up on the two tabs top and bottom and remove the fan you'll want to gently peel up the ends of the rubber vibration pads to get to the phillips head screws mounting them to the fan itself. Unscrew them, then screw those tab brackets to the new fan and push the rubber sticky backed vibration pads back down over the screw heads.

The side of the fan with the support struts is the side the air blows toward so make sure that's the side of the fan that will rest up against the cooler (if mounting the fan to the front of the cooler tower blowing to the rear). Might help so you don't accidentally mount the replacement fan the wrong direction and save you from having to do it again.

I did that flick test you mentioned, the CPU fan won't even spin once, all my other case fans do several revolutions. So yeah it's a done deal. Thanks for the info dude!
