Couple of Vortex III questions

I have a Vortex III and have noticed that if I play a game the right fan speeds up because it's cooling the GPU (I'm guessing). However after I close the game, even after 20 minutes or so, the fan stays at full pelt blowing out freezing cold air. The only way I can "reset" it is to close the lid on the laptop to sleep it and open it again.

Which leads me to another minor issue, when I sleep the laptop and wake it again the keyboard backlight doesn't come back on. I have to click FN and the Backlight button twice as if to turn it off and on again. Is this normal?

I always use Speedfan to monitor my temps. On my Alienware which has the active venting its a royal pain as it conflicts but on the laptop its perfect.

I've noticed the same thing with the GPU fan on my Vortex III. It usually needs a bit of a kick to make it stop. Either shutting the lid, or opening another application, such as 3DMark is enough to 'reset' it and make it stop blowing. Otherwise it will just carry on for hours.

As for the backlit keyboard, mine switches back on automatically on waking up from sleep.

I normally use speedfan but the problem is it gives me every temperature I need except the GPU.

Another question I have is how do I check for updates to my AMD Radeon 7970m? Their site says you have to go to the manufacturer for driver updates on laptops with switchable graphics but PCSpecialist was not on their list, nor can I find anywhere for drivers here.

I also have a Vortex III with the fan spinning issue.

I know how to recreate it but not how to stop it happening.

Basically, while running something that uses the GPU, the fans will spin up/down to cool the GPU as needed. However, if you quit your GPU application while the fans are spinning and the switchable graphics switch back to CPU, the fans will continue spinning until you either restart/sleep, or once again run something that switches the graphics back to GPU.

I think what's happening is that the 7970 drivers are controlling the fan speeds. But the drivers are only active if the switching is set to GPU. If the drivers are not active the fans will continue spinning at whatever speed they were going when the GPU app was last closed. So, if you run a game, the GPU fan control kicks in and speeds up the fans. If you exit the game with the fans spinning at high speed, the AMD driver cant drop the speed back down because the graphics have switched back to CPU. If you leave the game running on a menu or something, till the fans stop, and then quit, then all is well.

I hope that makes sense?

In a nutshell, I'm convinced its a driver issue and hope its fixed in a future update.

Well, the new 306.23 Nvidia drivers fix the fan issue on my 675M... but... it proceeded to eat up power and reduce battery life to the extent that it halved! Tried to tweak the power management settings to no avail, so have had to rollback the drivers today because it was getting silly :(

I should of just said use GPU-Z and click the second tab. You can keep an active log by checking the box at the bottom.

There should be some new drivers very soon. Hopefully with some big new improvements!! Probably within 2 months.
