ASUS ROGgl702vm (and GL502VS,GL703GE) Fans always max speed even when IDLE-WORKAROUND

Hi Everyone ! I have seen some post in the past about this issue, but none of them seem to have a solution and seem to be abandoned. I have been having this problem for quite some time now.. and while its been on and off, with every windows update it seems to get worse.

The problem concerns the CPU and GPU fans both. The CPU fan is almost always the one on max.

The problem happened, as it did with many others, after the failed windows creators update, that kept coming back and back after failing until there was a workaround by disabling the secure boot on the ssd and installing it manually rather than letting it do it by itself. All was well and good, but after few days noticed that the laptop sometimes would spin the fans up to max for few seconds (even if it was idle ) and then go quiet again. After few weeks it would do that for the first 20 minutes of being booted until it gradually went down and stayed at a normal speed and responded to actual temps and not its own whim.
Fast forward few months to today and the fans just randomly speed up to max and stay there for the whole day, sometimes shutting it down mid rampage and turning it on again would solve the issue, but most time it would not.
If I was gaming 24/7, the unbearable fans noise would not be a problem, but I started to use it as a youtube machine during working hours and gaming later it, just kills the nice quiet stillness in the office with its space jet engines while doing the most minimal tasks.

I have tried the NBfC while its good indicator which fan start to act up, it does not have a profile for the laptop and it struggles to keep the fans at bay once they want to go full speed. It sort of chokes them up and they keep coming back in bursts, so its not really a solution, but even more of an annoyance. The fan speed indicator also does not pick up when the fans are acting up, it always shows them to be at 12.5% even if they are at max, but once the fans act normal again, the indicator seems to represent the values more accurately. It's almost as if the fan controller is not communicating properly with the sensors.

I have not re-enabled the secure boot as from reading the workaround threads many people reported it would not boot up again.

Some things i have noticed is that the CPU is running at boosted clock speeds even when idling, however during the times of bliss and quiet when the fans are under control the temps keep around 45 degrees with the boosted clocks still there, so I am not sure it is the culprit rather than a symptom of what ever might be causing the issue.

I live in quite warm climate so the temps are normal to be like this, they never go above 80 under load and for a thin machine i would not expect more of it (apart from a better air intake for the fans, which are obviously starved for air with this design)

If anyone has a solution they might have found or any ideas of what i could try to solve the issue, I would be most grateful !

THESE WORKAROUND MIGHT ONLY BE TEMPORARY AND REQUIRE YOU TO REAPPLY THEM CONSTANTLY

EDIT 01/2021 :
Another possible workaround:
1. Remove and reinsert the wire going to the left fan.
2. Remove and reinsert the wire going to the right fan.
3. Disconnect and reconnect the battery.

EDIT : Possible Solution for anyone looking for an answer, from the last post on the thread.
I have tried with my gl702vm, moved some cables around so there would be no contact with any part of the motherboard and removed a tape that was used to secure the cable to some components. Didn't have a single instance of fans ramping up. For now this seems to be the main workaround.

Pretty much true in my case. If you're having the same problem as I did, all you really have to do is move the wire connecting the fans to the motherboard away from components on your laptop.

My story here: https://forums.tomshardware.com/threads/why-is-my-gpu-fan-insane.3532974/post-21412825

It's a really dumb design flaw. Not ragging on ASUS at all, you can't really predict this is going to happen. Just seems like it's receiving either heat from components they're touching, or EMF interference from being so close.

Shouldn't take you more than 30 total minutes to fix it. Please let me know if this helps someone so that we can figure out whether or not I accidentally fixed something else isntead, haha.

Ignore every other software,utility, driver and BIOS speculation.
The problem with the fan is the wire connecting it. It is either caused by the connector not connected properly or some interference from the chip that the wire hangs over.

I looked up a video how to teardown the laptop. The GL703GE is very easy to work on. The video is here:
https://www.youtube.com/watch?v=ix4eD2506oQ

From that video, you can see below that the wire in the video is looped around a resistor or capacitor or something (some silver cylinder). It does NOT hang over the chip near the fan. My machine, and most other pics I have seen online, show the wire handing over the chip that is just under the person's baby finger in the picture below.

I looped my wire the way it shows in the picture, made sure it was connected (it already was), and the problem has never happened since.

Update:
Warranty said it's defective motherboard, they replaced that for me, though had to wait almost 2 weeks, and said i'm not first one with these models to come there and problem is the same. With radeon updates did not do a thing but even if with nvidia it can be solved it will happen again later on, probably best to change mb while warranty lasts.

I'm running window 10 and haven't had this issue. Does an update cause this problem?

Probably but not sure, but it looks like everyone started to talk about this problem at same time (+- 1-2 weeks) and mostly newer laptop users.

Hello madbty,
Please kindly send your device to service center for further examination.
It is not about fan control. Thermal needs to be checked as well.
Thank you.

I have tried the below as suggested in previous threads, it worked for me now, right now at 52C the fan speed is at 2600 RPM, when I was playing dota2, temperature went up to 80C and fan speed at 5400 RPM. It will leave it like this for the time being, may take it to service centre after the pandemic.

1. Remove and reinsert the wire going to the left fan.
2. Remove and reinsert the wire going to the right fan.
3. Disconnect and reconnect the battery.

Hello, I really don't think its about thermals, the fans ramp up with the computer doing absolutely nothing. Any third party app that can check the temps show they are at normal idle range, so unless the device is just plain unable to detect thermals reliably i think its and issue with faulty hardware in a whole batch since its not a one off issue and happens to many people. The only workaround with the wires only solves it for awhile, then it comes back and is as annoying as ever.
