The CPU fan stops working suddenly and doesn't restart - ROG Strix G713PU
Hello,
I've had my ROG Strix G713PU for about a year now without any issues, but recently, I’ve been experiencing fan problems. This started about two weeks ago and happens roughly 50% of the time.
Under normal workloads, like light gaming or digital painting, both the CPU and GPU fans typically run at 2300 RPM and 2500 RPM respectively, which is normal. However, after about 10 to 20 minutes of use (with no change in workload), I notice that the CPU fan completely shuts off, dropping to 0 RPM. Meanwhile, the GPU fan still runs at 2700 RPM, but it sounds much louder than it should—almost like a blow dryer.
This loud fan noise persists for about 30 to 40 minutes, after which the CPU fan turns back on, the noise levels return to normal, and everything seems to balance out.
Here’s what I’ve tried so far to resolve the issue: I’ve reinstalled Armoury Crate, run the Asus diagnostic tool (which shows no problems when both fans are running), and received an error message when only the GPU fan runs, indicating a possible fan issue. I’ve also reset the BIOS defaults during startup and tried using GHelper to manage the fans, but no luck. I've also tried a BIOS reset by holding the power button for 1 minute with the charger plugged in.
oh, and some additional information;
I noticed that when only the GPU fan is on and very loud; if I unplug the AC charger it kicks into "silent mode" (both fans then read at 0 RPM) and then when I plug it back it in, automatically switches to "windows mode" At this point both fans spin again for about 30 minutes and then the CPU fan stops spinning again and the GPU fan gets really loud.
There's no grinding or crunchy sounds from the fans.
Could this be a motherboard circuit issue, hardware, or a software issue?
Any suggestions before I consider requesting an RMA?

Thank you for your time I know this is a lengthy post
Welcome to the forums, newcomer! I would like to try disabling Armory Crate in BIOS and then removing the app from the OS entirely. This app is actually identified as malware. Speaking of BIOS, have you verified if the laptop has any pending BIOS updates? I've also attempted a BIOS reset by holding the power button for 1 minute while the charger was connected. The proper method would be to disconnect from the wall. If there are no warranty void stickers, take apart the laptop, detach the battery, press and hold the power button for 30 seconds to discharge any remaining power, reinsert the internal battery, and then reconnect to the wall. Does the problem occur only with battery power? Have you thought about reducing the processor and GPU voltage?
Thank you for the friendly introduction! I wasn't aware that armoury crate was classified as malware. There were reports about it consuming a lot of resources.
I verified there are no BIOS updates installed, and my system appears current.
I should note that I disassembled the laptop, unplugged it from power, removed the battery from the motherboard, and performed a reset by holding the power button—though it didn’t resolve the problem.
I’m considering lowering the voltage on the GPU and processor, but I’m unsure of the exact steps.
The issue appears when connected to the AC adapter; fans operate normally for 30 minutes before the CPU fan becomes unstable and shuts down.
Could you think about whether this points to hardware failure or a motherboard problem, especially since the CPU functions initially but then stops unexpectedly?
