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

toske
Level 8
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.

I don't know about your model but Armoury crate You can modify the GPU and CPU fan speeds via the manual setting.

If the software detects and supports of course.


Sadly only newer models have the manual control older ones have nothing. Tried it on mine - no options to control the fans.

Hi folks,

Just wondering if there's anyone out there who has found a permanent solution to this fan problem?


I've had my GL702ZC laptop for about 3 years now and in that time it's been really dependable and virtually problem free. This fan issue however has been happening for a couple of weeks now. Within seconds after the Windows login screen the laptop fans go straight into top speed, producing a very, very loud noise that is simply impossible to tolerate for more than a few minutes. The weird thing is that the air coming out is completely cool so it doesn't seem to be a temperature related issue - it's happening even in an idle state with no programs or processes running.

I've searched this thread and different forums online and it appears that indeed others have had this exact same problem with this laptop model. I have tried some of the possible workarounds that have been suggested- updating the BIOS (two of the most recent versions provided on the ASUS support site) uninstalling and reinstalling the graphics card driver and adjusting the battery power settings, but to no avail. I have opened up the back to inspect the fans/battery for any loose connections yet everything seems in order and there is nothing noticeably amiss. I tried a clean install of Windows 10 and had no luck with that either. Other users have reported that since the excessive CPU fan speed is showing up in the BIOS (at over 6000 rpm by the way) then this could be a problem outside of Windows.

Something of interest was mentioned in the post below, where the user experienced a small power surge at their home created by a toaster.

https://rog.asus.com/forum/showthread.php?97605-GL702ZC-laptop-fans-running-on-100-inside-BIOS-UEFI-...

They claimed that the problem with the laptop did not arise until many hours after this, so thought it was unrelated. I don't know if it is a complete coincidence or not, but the day that this problem occurred I also experienced a very brief power cut that lasted literally a couple of seconds, with the laptop fan issue beginning to occur within minutes of this happening. However, I'm not convinced that this was the cause either. I do remember two different occasions several months ago when the laptop would not wake up from sleep mode and the fans did get really loud, just like now - I could not log back into the system and just had to forcibly turn the machine off with the power button. Things did return to normal again after powering on and off again but I guess it's possible that the fan problem was brewing even back then.

I logged a support ticket with Asus but the reply I got back today just suggested to update the BIOS, which I have already tried (and told them that I did in the email), and it didn't work. The alternative, sending it to the nearest Asus support depot (which is outside my country) is not viable - the machine is long since out of warranty and so with the combined cost of freight and repairs, it would probably cost more than it's worth!

I am considering replacing the fans with new ones - although they're doesn't seem to be a problem with their functionality, maybe there is a dodgy wire that is not communicating with the motherboard or thermal sensor or something. However, I'd like to know if someone else has had any success with this before potentially buying new fans for no reason.

If that doesn't work I'm at my wits end with this!

Any help or comments would be appreciated

Cheers

Hello
I have a GL703GE and for a long time the same issue.
Recently i have installed Armoury Crate, i put both fans in silent mode... and the problem gone...
Will keep inform if it is sustainable or not.
Cheers from France

Hello

Three days ago i have installed Armoury Crate and set both fans in silent mode
The problem is gone..
Will post later to update if it is sustainable

EDIT : after 2 days of silence, the GPU fan is coming back to maximum speed and noise...

Yeah, that seems to be the same thing I'm dealing with... I get some peace for a short time, then its trying to take off.

Is anybody else's fan perfectly fine while actually gaming? If I play a game, the GPU gets hot and then the fans act just like they're supposed to (well, for the most part). I can get nice quiet gaming, but loud and obnoxious low energy internet browsing.

I had the fan problem for years with my GL703GE. I even ordered a new fan assembly but never put it in because the problem would come and go.
Fans go on to turbo mode when rebooting, then off after awhile, then on again.

I have the latest firmware, Armoury Crap, BIOS, etc.

It drives me nuts when the fans come on, I can't even think straight when it acts up. Just stumbled on to the fix of moving the wire away from the small chip assembly unit. I just moved the fan wire assembly over that cap and taped it down with some electrical tape. Problem gone.

I thought it was a BS fix and had little faith it would fix it, but it did. So thanks OP and everyone else. Now I can live.

Hello brother,
my CPU fan of ASUS ROG GL503ge has the same problem. I am now fed up with my notebook. Would you please elaborate on the step you have taken? Which "small chip assembly" is that actually? And what exactly " over that cap" did you mean?

Never buying Asus again.


I've bought a lot of ASUS motherboards over the last 25 years, with minimal problems. One of the motherboards is now 21 years old and still running (24/7 for the last 9 years). I've bought two ASUS laptops in my lifetime - they provide exceptional power at a reasonable price. Both laptops have needed some TLC after a year or two, but I have been very happy with both. I have also owned a few Dell laptops - they never require servicing and they never die. However, you will not get the same power, or the ability to tweak, modify, and upgrade that you do with ASUS. My take is that ASUS makes products for enthiusiasts, whereas Dell makes products for those craving reliability and longevity.

I too was angry about the fan problem, but it's gone now, and I have to say, this is one fantastic machine.

Mine is GL520VS and having the fan speed issue recently, I went to ASUS drivers page and download the graphic driver which is recommended 399.24 instead of the latest nvidia driver, and so far the fan speed issue is gone, probably I just stay with the 399.24 version cuz it doesn't seem there's a huge difference in gaming. I compare the version 399.24 and the latest one by playing assassin's creed odyssey and actually the average FPS doesn't change at all
