7811-tilt to heat gpu for fun

I found this out when I put lappy sideways on lappy stand so I could lay on my side and see it on floor. If you tilt the lappy to the left (dont block any vents)the GPU temp reading will start to rise before your eyes. Interestingly, the air coming out of the gpu fan will become COOL. The only reason I can think of is there some heatpipe fluid that wont flow when its tilted like this. It dosnt do this when its tilted the other way. Kinda annoying to me because I like to read with it that way sometimes. Try this out yourself you should get same result. I consider this a weakness in the cooler design. I wonder if it would likewise fail in zero gravity? (not that it would matter to me). I wish I could find an alternate cooling setup that wouldnt do this (and that I could control the noise better). I would pay some money and sacrifice some battery if I could find such a thing.

 

Can't you just rotate the display?

 

what did you mean by fluid in the heat pipe

good idea, thanks lol. I just tried it, but Nvidia control panel wont do it.
It returns message about trying a different resolution and/or refresh
rate, which makes no sense to me. I tried several resolutions thought I suspected it wouldnt help. what am i doin wrong?

 

I noticed this same thing when trying to read while laying down on my bed.

Most likely your problems with rotating the display comes from driver incompatability. I had the same problem when using the laptopvideo2go drivers for vista. When I switched over to 177.85 xfastest drivers I was able to rotate the screen again.

And as for why the temps start to go overboard, more than likely its just the sensors that mess up with the 90* switch in gravity. I also had them go way up, but the entire computer was actually cool to the touch since the fans were blowing full blast for no reason.

 

hmm never heard of gravity affecting sensors. Im sticking with my theory.
check your experiment again..heres why I think its something like heatpipe issue... fan air starts out warm before rotating laptop, then after rotating temp reading goes up and air temp goes cool...seems like heat is not getting to 'radiator'...yeah i might try new vid driver later...got new problem headphones out wont work or switch of internal spkrs

 

Yea I think your probably right, I've never heard of those liquid heat pipes before.
