Hi there! I'm sorry if this is the wrong place to bring this issue, but I'm a bit of a newbie when it comes down to diagnosing a problem with my computer and wanted to ask some people who actually know what they're doing.
Around a week ago, I started hearing a faint bit of rattling and whining in my exhaust fan. I know it isn't the GPU fans, because I tested each piece within my computer to track down the source of the noise. I've heard a broken exhaust fan before (and actually just replaced it about four or so months ago) and thought that it a) maybe needed to be cleaned or b) had a faulty bearing, so I went for option one and cleaned out my entire rig with compressed air from top to bottom. When I plugged everything back in, the sound was more or less the same, and as I left it running to test it, the fan itself began...well, screeching. I turned off my computer (because I was a scared baby) almost immediately.
After everything had cooled down and I was feeling particularly brave, I tried turning on my computer once again. It made a little bit of a stuttering, kind of stopping sound once at the back fan (kind of like the blades were heavy) but began to run. After that point, I noticed that the fan cooling my CPU began to run at half speed. Both fans used to run at 3000 RPM/1000 RPM respectively, now are running about 2500 RPM/500 RPM.
Now, my fans (both the one cooling my CPU and the exhaust fan blowing out of the back of my computer) both seem to speed up and slow constantly, almost revving. It isn't something that they're doing to cool off my computer, because this is something that happens at idle times and my CPU itself is never under heavy load unless I'm gaming. I've went to a few different sources and did some research here, but it appears that people either say that the fan blades are laden with dust (which they are not) or there may be a problem with the motherboard.
I know this thread is kind of a mess, but I am a completely uneducated computer person and tried to explain to the best of my ability. I guess my questions are:
a) What the heck do you guys think is the problem with my computer, given the details above?
b) What can I do to fix it?
c) Could two different fans of different RPMs in proximity to each other on either side of a liquid cooler have adverse affects on one another? Could this be the reason why my exhaust fan died quickly, or do you think it was just a defective model?
For people who like to see the electronics themselves:
The motherboard is a MSI 970A-G43.
The cooler is an Asetek 550lc.
The exhaust fan is a Scythe Ultra Kaze.
The cpu fan is a standard 120 fan.
