Grrr... problems with attachments/pasting it in the post. Here's a dropbox link.

Hola Chico: Level 30 Robots/Traps Mastermind
I have noticed the exact same thing with my Nvidia 460 card.
I use EXPERtool to control my fan settings and noticed it has jumped from being into green which is usually 60-65 o'c to quite firmly being in the orange 80-85 o'c, I haven't changed any graphics settings within game.
Too many 50's to list here's a few you may know.
Slazenger, Area51, Area53, Area54, Erruption, Mind Plague, Thresher, Sheath, Broadside, Debt
Bump. Any advice?

All processors, be they central processing units (CPU's), graphics accelerators (GA's), graphics processing unit's (GPU's), network processing units (NPU), sound / audio processing units (SPU / APU), and even Physics Processing Units (PPU's), all have defined maximum clock-speeds. Outside of direct user-intervention, such as increasing the voltage to the processor, or increasing elements of the processor's timing mechanisms, this means there is a hard-cap to the amount of work that any individual processor can accomplish. The hard limit to how much work a processor can accomplish means that there is a hard limit on how much heat that processor can put off, a limit that is referred to as the TPD envelope, or Thermal Design Power: http://en.wikipedia.org/wiki/Thermal_design_power This heat output is often measured in Watts. Most processor vendors rate their processors by some variant of the Thermal Design Power. AMD, for example, sells their processors with explicit maximum TPD ratings: List of Phenom Processors :: Phenom Processors For Sale. Other vendors, such as Intel, have caught flack for selling their processors using figures from Average Thermal Load, instead of the maximum thermal load. The maximum TPD is a incredibly important figure for vendors actually building products with various processors. This CK8 cooler from Cooler-Master, for example, is only certified for dissipating up to 110watts. If you were to try and use it to cool off a processor with a 125watt rating, you'd probably wind up with a fried processor very, very quickly. Presuming that the manufacturer of the processor was accurate about the thermal performance of their processor, outside of user or external intervention, there should not a case where a processor being used in a default setting should be cable of reaching a temperature where automatic shut-offs engage. Referencing the external intervention, build-ups of dust, dirt, or other such debris can impedes adequate and proper airflow to system processors, creating an overheating situation separate of any software variables. |

All consumer processors are sold by maximum enabled clockspeed. You buy an AMD processor at 2.8ghz, you expect it to run at 2.8ghz. You buy an Intel processor at 2.8ghh, you expect it to run at 2.8ghz. You buy a RadeonHD 5850 at 850mhz, you expect it to run at 850mhz. You buy a GTX 480 at 700mhz, you expect it to run at 700mhz. The maximum clockspeed also means there is a hard-limit to how many instructions a chip can possibly compute at one time, also known as instructions per clock, or I.P.C. The hard limit of any chip's I.P.C. means there is a hard-limit to the amount of work a processor can accomplish. Since there is a hard-limit to the amount of work the processor can accomplish, there is a hard-limit to how much heat a processor can put off. This hard-limit is referred to as Maximum TPD, or Maximum Thermal Design Power. Chip vendors generally tell the OEM's and ODM's what the Maximum TPD's for their chips are, allowing the OEM's and ODM's to properly prepare and manufacture appropriate chassis for the chip products. Some chip vendors, such as Intel and AMD/ATi go a step further, producing their own reference heat-sink designs, and cutting down the research and design work required for an OEM or ODM. Under most default circumstances then, outside of direct user-intervention, processors should not experience a situation where the chip can overheat. |
If your cards are, for whatever reason, actually overheating, both of you would need to contact Nvidia.
Slazenger: Right off hand you may have a major problem. If those temperatures you gave are accurate, you're GTX 460 is pumping out twice the amount of heat in Celsius than it should: http://www.bit-tech.net/hardware/gra...card-review/11
If those temperatures are in Fahrenheit, your temperature monitor IS NOT ACCURATE.
Branman: My suspicion is that you are seeing a memory leak. There's a bug on AMD cards right now where the game cuts off and crashes with certain AMD driver sets.
It's possible depending on the Nvidia driver you have installed that you might be experiencing a similar memory leak.
My computer seems to be overheating since the last update to Live. I've only had it happen while playing CoH. I've played hours and hours of Arkham Asylum lately with no issues, but CoH quits on me after an hour or so lately.
Here's my DxDiag. Thanks for any help.
