Fans keep running after game closes

Hey, I'm using a Sager NP9150 with a 675m and the only problem I really have with my laptop is that after gaming (can be any game) the fans keep running.

One workaround I found is to quickly open the game again (say SC2 or Diablo) and close it again. This makes the fans run at normal speed. Another way I found to work around this issue is to open MSI Afterburner and then close it.

I'm not sure if I'm explaining myself well here but it's like something should trigger the laptop to shut the fans down after a game is closed, but it doesn't happen all the time.

Could it be drivers or BIOS?

 

I'm guessing it's the BIOS. I used to have this problem with my P150em with a 7970m, and I did exactly the same as you (I opened and closed diablo 3 to get the fans back to normal)

I changed my 7970m for a 680m and when they swapped the GPU they also changed my BIOS (it looks completely different now)

Now with my current BIOS my fans always go back to normal after I close down high performance programs (games, fraps, NVIDIA inspector).

 

Any idea where can I find those BIOS?

 

I assume its like a car engine, the fans keep running until it reaches the specified temperature even if the engine is off.

 

Not the case for my 9170. After updated to the latest 06 ec and bios I still hv to open kombuster to make the fan stop

 

So it seems to be a known issue. Where do you get the news BIOS by the way?

 

Does Fn+1 make your fans go into turbo boost? If it does, try activating that, then deactivating turbo fan, and it usually quiets down. Other than that, your GPU won't drop in temperature after you close the game, so yeah, it'll keep running until the GPU is back to idle temperatures.

 

I didn't know about the Fn+1 combination, I will give it a try tonight.
Any other trick I should know about?

 

just here forum. u can see a post about bios and just updated 1.00.07

 

I have same problem
after game fan will run non stop even at 35C
when I open kombustor fan shut down
it will turn on again at 50C

 

Hey Guys, heres your technical background 101 on this issue.

So right now the BIOS on these is set to whats called dGPU power-off. So when the dGPU isn't needed it shuts it down to save power. Now the issue comes in is that lets say you are gaming for a while and heat that thing up to 90C or so. By the time the BIOS shuts down the dGPU its only at like 65C. Once the dGPU shuts down it doesn't report its temp any more, so the EC just assumes its the same temp as it used to be, and keeps the fans spinning. Thats why when you wake the dGPU back up the fan gets quiet real quick, as it finally gets a new temp reading.

EC06 in the P170 fixes that, but it still hasn't been ported to any of the P15x series yet, for reasons we don't know and they don't seem to be telling.

The other mode keeps the dGPU always on but at really low clock-speed, but that just drains the battery and doesn't increase performance AT ALL (we've set that mode and looked to see if it helped, it didn't at all didn't solve a single issue), but it does keep the fan speed true lol.

 

I'm not sure I got that right. Is leaving the dGPU always on Clevo's solution, or that's another one?

 

No they shut the dGPU completely down to save on Power, the OTHER way they COULD do it would be to leave it on but asleep.

 

then why the fan speed still can keep change from higher to lower after i exit the game? according to your theory the fan speed should keep at the same level right after i exit the game instaed of still being able to change after i exit the game.

 

The fan speed stays the same when the dGPU is turned off, not necessarily when you exit a game. You can exit a game, but the dGPU might still be active for any reason.

 

If you have any dGPU monitoring programs running, it'll prevent the dGPU from shutting down and result in what you are seeing.

 

no i dont have. i wait until the fan back to lowest speed and stay there for very long then i have to open kombustor to make it stop

 

There is a delay when you turn off a game and when the system shuts down the dGPU, it does that just so there isn't a constant switching on and off. And also to give it a chance to cool down. Sometimes it just doesn't cool down fast enough

 

so by what means i can monitor when the system switch on/off the dgpu?

 

I know that need time to cool down but fan will run for hours
gpu cool down and fan will spin for hours.I must open kombustor or restat laptop to shu down fan.

 

Monitoring also means using the GPU, you can do a test yourself, while gpu/fan are off, turn on monitoring programs like GPU-Z and watch the temp, you'll find that the temperature will start to increase, and your fan will start spinning again.

 

so using this i can know when it is on, then what can i use to know when it is off?

 

If you open HWINFO64 and found that the dGPU isn't captured, that means it's off at the time you launched HWINFO64. The way monitoring program deal with the dGPU is by requesting the temperature at a 2 sec interval, if you have an nvidia gpu you can turn on the gpu activity indicator and launch GPU-Z, you'll find that the icon on the taskbar blinks because GPU-Z keeps requesting temperature from the dGPU at a 2 sec interval.

 

i saw hwinfo64 cannot capture immediately right after i exit the game, however, accoding to mythlogic's reply in this thread earlier, the dgpu is not shut down immediately. what's the problem here?
