Fans Don't Completely Spin Down After Gaming (P150EM)

Hi,

The idle fan noise of my laptop is pretty quiet; i.e., if I'm just browing the web, or word processing. When I game, the fans start whirring very loudly – this is to be expected.

My issue is that even once I have closed the game, the fans start whirring less, but never return to the quiet levels that they are normally. I have to close the lid of the laptop – putting it to sleep – and then open it again to make the fans return to normal.

This solution does not seem ideal, so if anyone has any advice on how I should diagnose this problem I would greatly appreciate it!

 

is it a sager or a clevo like the title says (or some other clevo variant)?

 

What are your idle temps? My p151em idles at like 40 and it goes up to 50 while browsing the internet which causes the fan to spin up to get it back down to 40... Pretty annoying.

 

i think you can try open MSI kombustor and closing it right away or something. whats your gpu?

 

The laptop is not turning off the gpu fan. It's a known BIOS bug, and so far there's no real fix.

I'll try to keep it simple: when you close the game, the laptop will switch to the integrated graphics, turning off the dedicated nvidia/amd card. Because it's off, the laptop can no longer read the gpu temps, and won't turn off the fan, even if the gpu is already cool enough.

Honestly it annoys me a bit as well. When I quit a game, or anything using the Nvidia card, I have to wait for the gpu to cool down, open something that uses the dedicated card, for instance 3DMark11 (don't need to run the benchmark) and close it when the gpu fan stops.

 

Do you have turbo fan mode? (fn + 1) If you do, just turn it on and then turn it off immediately and it should fix the problem

 

ive been using this sollution (almost same as jonny's)
i normally have nvidia inspector, core temps and sometimes msi afterburner running on desktop.
once you close the game as mentioned the fans keep spinning on high. as soon as i close the monitoring software on desktop the fans stop immediately.
as mentioned by jonny its some sort of bug and either opening and closing a bit of software will do the trick.

edit:

Fn + 1 doesnt work on this latest model (P150EM)

 

Did you ever clean the dust off your computer? Maybe it's clogging up the air flow and causing your computer to idle at a higher temperature.

 

I give it about 20-30 seconds after the game is closed and then I start MSI Afterburner and the fans die down.

If all else fails, just activate sleep mode and wake the laptop up immediately after. Ahhh, peace and quiet

 

that's what i do and where i was going with trying to figure out whose bios op has.

This usually works fo me, i have a new P150EM as well. Still after some seconds the fan reawakes a bit, not as loud but still noticeable in a quiet room.
Clevo should really implement a hotkey or a bios update to fix this properly.

In my case it still reawakens a bit, but i guess its the CPU fan and that cant be helped much...

 

what bios have you got as as far as i know Fn + 1 doesnt work on the latest P150EM

 

the sagers do. it's available on any NP91x0 (i.e. sager's bios).

You didn't say what card you have, if it's the HD7970m, opening Catalyst Control Centre works like a charm. This is what works for me.

 

he does have the 7970 according to his past posts.

OP listen to this man and see if that works

 

Fn+1 does work on the newer models, it may be a BIOS update that was released that changed this. If I recall, the early ones we had did not have the Fn+1 function. I will check on this.

 

thats interesting, ive just run hwinfo64 and mine is showing as P15xEMx and bios is american megatrends 4.6.5 and Fn + 1 defo doesnt work for me and the lappy is only 2 months old.

 

uh, i'm telling him that it does on my sager (which awakeN can corroborate). there is nothing about a newer or older model, or any bios update. again, "turbo fan"/Fn+1 works on the sager NP91x0 models and the NP9370.

right, you don't have a sager.

 

so even though its exactly the same model because its sold by sager yours works but every other company around the world that sells them doesnt.

that makes sense NOT!

 

right. well with a slight correction--i can only confirm that it works on the models i've listed, and any company that resells sagers should know that it works on those sager models that they resell too.

 

so they must make some sort of modification to the bios or something like that.

oh well, i live in the uk so its ruddy cold most of the year round so i dont need overide fans

 

right, like when you asked...

...and i said sager's.

 

ahh i see. but what bios number is it

 

pretty sure it's the same american megatrends version p) but i'll get back to you on that. not at home.

 

I am aware it works on the Sagers we resell; however, I was not sure if his lack of this feature may be because he has a laptop built by a different reseller outside the US or if it was something with the BIOS. I do find it a bit strange that it was not a standard feature regardless of where a person purchased it from.

 

while you wait, look into embedded controllers.

dude, honestly... if anybody should be held to a higher standard in terms of spreading misinformation on this board it's you. he obviously didn't buy from a reseller. he states it quite plainly in his sig. go read the sticky if you don't understand what type of business you do. we don't need you to be stating anything while you go check on it.

 

I had the same problem with the stock driver of Clevo. Since I used the driver here Catalyst 12.8 WHQL UnifL for ATi+Intel Graphics, the fan automatically turns off after I close the game. The card is also better recognized by Windows.

 

interesting read embedded controllers mattcheau, thanks.

 

I am surprised Clevo never fixed this (though I probably shouldn't be surprised).
I have just noticed the same issue with GTX 680M, and quickly made small utility to fix it.
Basically, this utility does nothing visibly, except connects to GPU and reads temps from it - this appears to be enough to briefly wake it up and update the fan.
I've set it in Windows Task Scheduler to run every 10 minutes when on AC power only - so when I finish gaming, it gives 10 minutes for GPU to cool down, then briefly wakes it up and fan switches off. When fan is already off, it does not have any noticeable effect, since it does not actually place any load on the GPU, just read temps couple times.
I am currently testing it to find the minimal time to switch GPU on for EC to poll the temps and update fan speed, since instant on/off does not reliably work, currently trying 5 seconds interval.
