7805u FX laptop pulsing fan on left side

I have read quite a bit about this but have yet to find a good way to stop the dumb thing from pulsing up and down. The fan pulses high, then low...high...then low, over and over and over. This happens with the laptop completely elevated, power saver mode on (aero off), and nothing running in the OS. My GPU temp is 40-48c (never going above 48) and it continually pulses and annoys the hell outta me.

Anyone have a very easy way to manually set the fan speed on this....I honestly won't game much on the system, and the little I would game I can manually set it higher if need be. I'd like to allow the gpu ti hit 60c or so before crankin the fan at all....especially just in business apps.

Any help appreciated, sorry if this has been discussed a lot before but I could not find a definitive answer.

edit: or maybe I'm a moron and this is the cpu fan....which begs the question anyway....why would it be pulsing? I've never seen a core2 behave like this....I assume I need a bios update?

 

Im pretty sure thats normal and yes that is a cpu fan on the left. getting used to it after a while, was also annoying in the beginning.

 

No. It is GPU fan.

 

For me it only occurs when the computer first starts up. I think read somewhere that it's a little diagnostic test that the computer runs at startup to make sure the throttling is working correctly. Can anyone confirm this? If it's doing this all the time, then I'd say something's wrong.

 

Nothing is wrong ALL the 7811's had pulsing fans when they came out and i think most of the subsequent FX's did as well. BIOS updates helped. Now mine doesn't pulse (using BIOS .12) not sure if any of my upgrades are the reason or not...

 

Can anyone confirm that bios updates do in fact fix this issue. Mine does this constantly...it's annoying enough for me to return the POS.....that's just not acceptable IMO....if I wanted the noise of a desktop I'd buy a desktop. Just sitting idle in power saver mode doing nothing ...the thing should be dead silent

 

pretty much a standard issue, my 6860 does it, atleast i think it did, considering i havent had it since november

 

mine did it the 1st week, doesn't happen much now.

 

Does anyone know where I can download the bios flash for the bios that was on this stock? I was running the .17 out of the box. I flashed to the .12 and it appeared to fix the fan issue....but maybe too much. Looks like now in the OS my gpu is around 70c....uggg, the fan kicks on sometimes but seems very odd. Maybe cpuid hardware monitor is reading incorrectly. I can't handle the pulsing fans so I guess I'll stick with this bios for now, but wanted the .17 to see if it holds true that after a week it stops.

 

70deg on idle or some gaming? That's unreasonably high for idle. Should be 50deg range.

 

right now idle in os at 67c....it goes all over the place but that's monitored through hardware monitor from cpuid site. Before my bios update it was at .17 version of the bios, and was around 40-50.....but the fan constantly went up...down....up...down. Drove me insane.

 

P.S. Ooops, seems my reply is a bit too late

Hey, buddy, that's NOT normal. I had this issue too. That's what you need to do.

1) Try other drivers. You can find these at Definitive Graphics Card Driver Upgrade sticky. I use XFASTEST 180.70 because they give way much better FPS in The Witcher Enchanced Edition for me.

Still get these pulsing fans?

2) Try other BIOSes. You can download it also here, it's sticky too. I got rid of this pulsing bu flashing to .10 BIOS.

Your problem should go away.
