Uh, why is my clevo's GPU fan permanently on now?

Im using the clevo p150sm1b, and it was on the desktop idling with no graphic using programs on. Suddenly i heard the gpu fan's spin up loudly and stay on. Confused, i checked both CPU and GPU temperatures, everything was at about 50 degrees celsius, but the GPU fan was definately on at a high speed for no apparent reason. I restarted, and during the boot sequenec i confirmed that the GPU fan kicked back in and stayed on the entire time. GPU usage is at 0% now according to GPU-Z but the fan is still on at high speed....

So for some reason the GPU fan is on and refusing to shut off...i wasnt even touching the laptop at the time and the fan suddenly turned on for no reason. What is going on?

Assuming the laptop is placed upside down with the back cover off, with both fans closest to you, the fan that is permanently on is the one to your left. Was previously told this was the GPU fan.

P.S. Already using prema's bios mod in case anyone wanted to suggest that.

 

Turn computer off remove battery and press power button for 10 seconds. Then restart computer.
Check temps and fan speeds and report back.

If similar issues exist afterwards then return vbios back to default.
Yes the left side/fan is the gpu when upside down.

 

What do you mean by battery? The AC adapter? And what do you mean turn it off, remove battery, press power button for 10 seconds while it it is still turned off, then turn it on?

 

If you're already using Prema's BIOS mod, have you attempted the shut-off-gpu-fan trigger of FN + 1 x2? Or simply swapping between auto/max normally?

 

He means exactly what he said. Turn off PC. Remove power cord. Take out laptop battery. Hold power button down for 10 seconds. Plug back in battery and power cord. Restart.

 

Presisng FN + 1 twice just makes the turbo fan start and then turn off, but afterwards the GPU fan is still on. Not sure what you mean by swapping between auto/max?

Well i just tried the power off thing and press for 10 seconds....did nothing. Temps were normal after that as usual. So i tried flashing to the stock bios that prema provided but i dont see any change, the gpu fan is still going....

 

You said the GPU idles at 50C? The trip point for the GPU fan appears to be 42C, so if it's idling at 50C the fan will blow indefinitely. Check to see if any program is causing the GPU to be utilized.

 

Uh i thought the GPU is supposed to turn off when not in use, and therefore the fan wouldnt be in use at all? That used to happen (the gpu fan wouldnt start up if i was just on the desktop)

According to gpu-z the gpu usage is 0%...

 

FN + 1 in rapid succession should be switch off for GPU fan, and is a Prema BIOS feature. FN + 1 once is "max" fans for all your system fans, and FN + 1 again while on max fans is "auto" fans for your system. Normally your GPU fan should not switch off if it's not in use I think. It usually just idles slowly.

 

2 Questions for Question2

what gpu is it as you havnt mentioned that yet.
and also have you done something demanding earlier and the fans have kept going ever since or do you turn the lappy on and it stats fan and doesnt stop.

there is glitch on certain clevo's that after something demanding the fans wil keep going. all i do is open nvidia inspector for 2 seconds and then close it and the fans stop.

 

Its the GTX 770M.

I ahd a game on before the problem started, but ever since then the gpu fan has been going and its pretty loud. Weird...

I just tried hitting FN + 1 in quick succession and that appears to have done nothing.

I opened nvidia inspector and that did nothing as well.

 

strange one then as thats how i stop the fans on my EM laptop as i dont have the option of a hotkey for the fans.

 

Have you tried reflashing the bios?

 

He said he set it back to stock and it did the same thing.

Edit: I think in our technical-ness we've forgotten something.
OP, have you actually tried reinstalling the hotkey control software? I completely forgot about it, but instead of saying "hey reinstall windows!" we should try that first. It might fix any issues with the fan, since it works properly in safe mode but is full-blast in windows.

 

If the above solutions have failed to work inspect cooling grill/fans for dust and also try a repaste OP.
Good luck.

 

What do you mean by hotkey control software?

Ive already checked for dust and that doesnt appear to be the issue (the GPU isnt overheating either).

What do you mean by repaste? The fan itself has no thermal paste that i can see?

The fan also starts spinning during the boot up process, and i tried disabling the dGPU in the bios but the fan still stayed on...

 

Okay to confirm again, the fan on the left is the GPU fan right? (Thats what my reseller says and what people said on the first page).

I tried unplugging the fan after disabling the GPU, but a few seconds after the laptop went into windows, the laptop started beeping loudly and i quickly turned it off. Im assuming that was the overheating alarm, but that doesnt make sense if it was the GPU fan as the gpu was disabled....

 

According to your picture, the fan on the right should be the GPU. Also, unplugging the fan means the BIOS detects no fan installed and shuts you down to make dead certain you don't heat-destroy your parts. It is not an overheating alarm.

 

Yes there is no way of running these systems on IGP only.

 

Okay that clears up the confusion as i was told the left fan was the GPU before.

Now the question is why is the fan suddenly so loud?

I tried repasting the CPU heatsink, but even at idle with the CPU temps at 45-50 degrees celsius, the fan is pretty damn loud and much louder than before....and i just cleaned the heatsink and fan of dust (although there is still some dust stuck on the fan blades as i have no way of removing them atm). Im not sure whether i should try and repaste it again, how do you tell whether a repaste job was successful or not?

Im tempted to try rinsing the fan under water (without removing it from the enclosure) to see if it might help with the noise but im not sure whether that would cause some kind of damage or wash away any internal lubricants it might have...

 

If you feel it's debris compressed air is much safer. Water is never a good idea with electronics (or motors).

 

water, no way. compressed air and a small paint brush or Q tips (but not after youve used them in your ears)

when you screw the fans back into place there could be one side that isnt as flush to the base which can cause fans to sound strange.

 

So when you say that FN 1 turns the fans down but they immediately spin up again? This happens to me sometimes after a game, even a few minutes after the game has closed. The fans might think that the GPU is still being loaded but in fact, it is not. Do you have any programs using the GPU.

Just my guess.

 

I thought water was fine with electronics as long as you dont use them when they are wet? There are plenty of reports of people washing motherboards with water, drying them, and using them fine afterwards.

Ive tried using compressed air but it appears to be useless...the air flow is not strong enough to make anything move....

Its more that the CPU fan is much louder now for some reason. Its a pretty loud RRRRRRRRRRRRRRRRRRRRRR.

Djask : Its not the GPU fan.

 

Tried cleaning the dust off the fan blades with a q-tip, no difference.

While booting up the laptop again, i noticed that the fan was spinning but very quiet during the first 20 seconds or so but after that the fan sped up and became much louder. To put it into perspective even though its on prema's silent fan setting, its much louder than when i tested it with the cool fan setting a few months ago.

Not sure whats going on, but would resetting the CMOS battery help? Does anyone know how to access it on a P151SM1B?

 

Repasted the heatsink again, using less thermal paste this time.

No change except...right before i started writing this post, the fan went very quiet for a short time (30 seconds or less). I checked my temperatures and they were about 50 degrees celsius, the same as before the repasting. After that the fan sped up and the same loud RRRRRRR started again.

 

Hello guys. Had same issue with gpu fan. Suddenly run at max speeds (i suppose) without any gpu usage (gpu - z). Model p157sm-a. clevo 7 years and still same bugs?

 

What are your CPU/GPU temps at? You can install HWMonitor to tell you. Also giving the vents and fans a good cleaning could also help out.

If the fans are max speed you may have toggled it on accidentally with FN + 1 (not F1) try that combination to see if it turns off.

 

Hi. No one touched the laptop. Fan start running by itself. Then i checked gpu-z and hwmonitor to check temp of cpu. Cpu vent was fine (bcs of temperature, 40C). Gpu temp was fine too (30-35C). And yes when i triggered fn1+1 and back gpu fan stopped (as normally he will do/stay at this state bcs of gpu temp). So. It's second time fan(s) start turning on max by himself(theme self?, i didn't notices first time if it was cpu or gpu or both).
Thanks.
Possible serious hardware issue?
