So I borrowed a friend's infrared camera to check the insulation on my house, and thought I'd do something [H]ard with it.

The laptop is an Asus G51JX-A1, in various Power4Gear modes. Ambient temp was 77F, it's not on a cooling pad, it's sitting directly on an MDF 1" thick cubicle table. Software was 3DMark2006 with standard settings.

Power4Gear set to Battery Saving, Idle at Windows 7 Desktop. Coretemp reported 113F on the highest core.

Power4Gear set to High Performance/Extreme Turbo, Idle at Windows 7 Desktop. Coretemp reported 123F on the highest core.

HP/Extreme Turbo with 3DMark06 on its second run, whichever test is the Antarctic Outpost. Coretemp reported 161F on the highest core.

A shot of the left side where the exhaust fan aims. The wire is a USB cable for my G13 gamepad that I was using to monitor Coretemp with.

With HP/Extreme Turbo, on a fresh install of Windows 7 Pro using the drivers that came on the CD in the box for everything, I scored 9624 on 3DMark2006. Nothing has been tweaked.
 
Yeah, that does look pretty kewl.

I heard that the G51J has throttling issues because of insufficient power and when run without throttling can cause the power brick to shutdown. :eek: It would have been awesome to see an infrared comparison between throttled and non throttled under heavy load. :).

My Zalman NC2000 came in last night. I'm going to see if I can borrow the IR camera again, and if I can get it, I'll try the throttling thing.

If I'm feeling really bold, I have a 200+W Kepco regulated power supply I can put the laptop on if it shuts off the brick. I'll just need to go to the local electronics store to get the power jack.
 
I tried to figure out how much current the laptop pulls off the power supply, but ran into problems (my meter can't flow enough current.) But in case anyone is curious:

Battery Saving: 60% CPU Max at idle Windows 7:
0% Display = 1.2A
100% Display = 1.4A

High Performance Extreme Turbo at idle Windows 7:
100% Display = 1.8A

When I fired up 3DMark2006, it went to 5.2A then throttled because of the meter (I'm guessing.) I'll get a real ammeter and some real cables and try again sometime.
 
This makes me happy that I paid the extra $$ to have that diamond thermal paste put on my G51J3D :)
