Been dealing with this for a while, found a fix, see here:
(basically, it's most likely an NVIDIA driver issue)
As the title goes, I'm here to share my experience with the issues we are all facing.
After sending my laptop for a warranty claim, ASUS swapped in a new motherboard on my laptop and only worked properly for about a week before it goes havoc. This time around, it got worse than before. I decided to take the matter in my own hands and it had worked way better than expected. I followed all the steps in this thread along with some other forum threads.
- Reconnect the fan headers
- Discharged my laptop (disconnect any external drivers and charger. Hold down power button for about 20-30s)
- Reconnect the battery
- Tighten the heatsink screws (be careful with the warranty sticker, I temporarily removed it and put it back after tightening)
- Used a gaffe tape (Polyken 512 Vinyl Coated Cloth Gaffer’s Tape) to secure the connectors. Replaced a missing tape on one of the fan connector the technicians forgot to put back located below the m.2 mount.
- Wrapped an extra layer of gaffe tape around the exposed colored wires of the fan connectors (making it fully covered). I'm hoping this would reduce the "static" interference causing the fans to go haywire.
- Secured the fan wires by taping it to the PCB to prevent any movement since I am travelling with it often
- Reinstalled Intel Dynamic Platform and Thermal Framework, updated to BIOS 311 and latest NVIDIA driver
- Set to Whisper Mode in Geforce Experience (not sure if it plays a role here but trying my luck)
- Reapply thermal paste on GPU and CPU with Noctua's thermal grease (had it in hand from previous builds)
- Send it in for warranty again and hopefully the technicians find another way
- [AFTER WARRANTY] Apply liquid metal for cooler temps
Steps taken has worked well for me about 2 weeks now. Will keep you guys updated on mine in a month. But do try it out. I did not undervolt my cpu as I want to maximize it's usage from my workloads whenever I'm not at home.
What else I tried: I put aluminum tape on the video card fan connection wire. A ground cover closest to a connector is routed to a mounting screw (with a unique aluminum tape). The healthy one was insulated in a circle with a thin Teflon tape. Since then, the video card fan speed control has become much better.
Have you guys disable fast boot and then restart or shut down? Most of my issues with the GL503VM dissapeared with fast boot.
