I posted this in the problems thread but it got locked, so I'm assuming it's ok to repost it here.
My (3D capable, if it matters) R3's GPU will throttle to the lowest performance state (state 12) the instant it hits 79C. I personally think this is extremely low, especially since I can achieve this playing Dirt 2 with my laptop flat on a table. Elevating it ~1 cm will drop it down to 76C, but since that is extremely close to the throttle point, come late summer this won't work. This has happened in all official Dell drivers as well as the 275 betas.
A few questions at this point:
Am I the only one experiencing this problem?
Is this possibly corrected in software?
Now, I know I can correct this myself with a repaste, or probably by calling Dell, but I want to see if this is systemic or software related first.

Honestly, I have yet to have any throttling happen on this machine, might just be crappy thermal compound in your case.

Well, I was able to get another 6 degree C leeway by forcing the GPU fan to run at max. For some odd reason, it doesn't spin at its maximum possible speed which would have been almost enough to stop the throttling. Normally, it won't go faster than 4200 rpm but it can run at 4700.
I'm still thinking about doing a repaste, but I worry that if it doesn't help, Dell would blame that as causing the overheat. I don't know as of now, as the fan speed adjustment isn't permanent. -
You are allowed to repaste, it does not void warranty or anything. Just tell them it was doing it already when you call.

Much to my disappointment, the factory paste job was exemplary. Very thin with no overrun, and it wasn't dried out.
The AS5 I used didn't improve things much, but I'll wait on the cure time. Judging by how I may be the only one affected by this, if things don't improve I'll just assume what I have is a very poor example of a 460m. -
Yup, I wouldn't wait on it to cure, it will only drop another few degrees. My laptop stays in the 50-60c range for the most part. Call them and have them NBD you a new GPU. You can have someone install it or do it yourself, takes 5 minutes to swap out
-
Are you OC'ing the GPU to get those temps?
Agree on getting a new 460m card if they are normal clock temps. -
The temperatures are without an overclock, but they are generated by running it at maximum load.
It's disappointing too, although this particular chip ran hot, when I could keep it cool it overclocked amazingly well. 880/1625 doing CUDA, 850/1600 doing 3D.
R3 460M GPU throttling?
