7811 overheating CPU with 179.48 drivers....

Hokay, this is a weird one. Can anyone think of a reason why these drivers would affect the CPU fan speed? I just began encountering an overheat problem after doing two things - buying an external monitor and playing with the laptop cover closed, and switching to the NVidia 179.48 drivers from the Nvidia site. The keyboard and hard drive area were scary hot after an Oblivion lockup, and my CPU temps were 50% higher than they used to be. I now have a cooler underneath and the laptop cover is left open 2 inches for airflow, but the CPU temps are still at the same level, so that's where I'm placing the blame.

Here's the story: My 7811 has been running superbly, with extremely low CPU temperatures because I am undervolting via RMclock and using the .12 bios which makes the CPU fan stay on higher than it ought after coming out of sleep mode I was using XFastest's 180.70 drivers with E-Wrecked's 21% GPU overclock, and nothing changed anywhere else.

The system was running PERFECTLY - GPU temps around 50-54c under the hardest gaming, CPU temps around 25c max, 16-19c normally. Unbelievable, and I was SO HAPPY with it.

Then I did two things. I bought an external 1900x1200 monitor and connected it via HDMI. And, I changed to using the NVidia 179.48 drivers because I was having an odd problem with Flash animations running slowly (this was just before the new monitor). It didn't fix the flash, but I now notice the following effects:

1. The CPU fan no longer stays on medium (audibly on and you can feel a good airflow). Instead, it's only on very low and never kicks up any farther that I can feel. CPU temps are now (via RMClock and PCWizard) 22c core, and I've seen 37c core under hard gaming. The overall CPU temp under the same hard gaming has been 50c as reported by PC Wizard. As said above, prior to these changes, the temps were 16-19c core, 24-25c core under hard gaming (never took the overall temp before).

2. Instead of the GPU fan turning off for awhile then kicking back on, it now stays on low all the time and kicks up to medium very often. The GPU temp is now 40c at the desktop (Aero disabled) instead of going to 36c and creeping back up to where the fan would kick on. So I now have a continuous wheeeeOOOwheeeOOOO from the fan instead of some minutes of blessed silence in between lol.

I'm not concerned about the GPU fan effect although I thought it worth mentioning. My real question is, does anyone have any idea why the CPU fan speed would be affected by the Nvidia driver change? That's where I think my scary hot keyboard and lockups came from.

Thanks in advance for any help!
Woot

Edit: Went back to XFastest's 180.70 drivers. The GPU fan is back to being quiet for a while, then kicking on. But the CPU fan is still low and the core temps are still 26 at desktop, so I doubt that I can put the lid all the way down when playing on my external monitor. Hmmm....

 

I have the same problem and it's not the drivers. I have tried many versions and the issue is only present when I have my external montitor attached. It's a Samsung 24", connected via HDMI.

I have been very reluctant to take it in figuring I would get some stupid run around because the montior is attached. Looks like I am not the only one then.

I guess I have to bite the bullet and take it in.

Anyone else with this problem?
