Fermi GF108 Temperatures
Benchmark tests are always nice, so long as you care about comparing one product to another. But when you're an overclocker, gamer, or merely a PC hardware enthusiast who likes to tweak things on occasion, there's no substitute for good information. Benchmark Reviews has a very popular guide written on Overclocking Video Cards, which gives detailed instruction on how to tweak a graphics cards for better performance. Of course, not every video card has overclocking head room. Some products run so hot that they can't suffer any higher temperatures than they already do. This is why we measure the operating temperature of the video card products we test.
The FurMark application has the ability to push the a graphics processor to higher strains than any video game can. Doing so generates maximum thermal load for a GPU. This makes FurMark an excellent program to use to find out just how hot a video card has the potential to get inside of your computer. Now, the fact that FurMark pushes a GPU to extreme highs means that the likelihood of a video card reaching the temperatures that we are representing as the high here is very unlikely. The numbers we put here are a representation of the maximum thermal output of a video card and don't reflect normal, real-world performance.
To measure the temperatures of a video card, I first measure the idle temperature using GPU-Z. Then I use FurMark to push the GPU temperature to the very limit. The ambient temperature of test environment stays at a stable 20°C. After I am certain that the video card has reached its thermal potential, I close FurMark and measure the highest temperature recorded by GPU-Z during the process. I do this because it has often been speculated that FurMark records higher-than-actual temperatures. It is interesting to note, however, that both FurMark and GPU-Z came up with the same temperatures for ASUS ENGT430 video card.
ASUS ENGT430 GeForce GT 430 1GB Video Card Temperatures
With the GF108 graphics processor being intended for use in a media PC environment, we would hope that the GT430 video cards would operate at relatively low temperatures. The ASUS ENGT430 is a low-profile video card and has only a small fan and heatsink cooling it. This works great for saving space in a small mini-ITX case, and it looks like it works pretty well for cooling this minimal card as well.
The ASUS ENGT430 is an interesting new card with an interesting purpose. Being low-profile and meant for a media environment, it is our hope that the ENGT430 doesn't put out a lot of heat. Most tightly enclosed HTPC cases aren't great at expelling excess heat. The ASUS ENGT430 can certainly be said to run at cold temperatures, but the results are less than surprising. Both the GF104 and the GF104 based cards run very cool as well. In fact, the NVIDIA reference GTS 450 tested here at Benchmark Reviews had nearly identical operating temperatures as the ASUS ENGT430. The ENGT430 runs idle at 30°C and undiscernable noise with an ambient room temperature of 20°C. After about 10 minutes of running FurMark's stress test, the ASUS ENGT430 was just as quiet and ran at 65°C. The fact that the ASUS ENGT430, at nearly have the GPU power, is running at the same temperature as a GTS 450 isn't all that difficult to understand. The low profile card has very little cooling going on. The ASUS ENGT430 has only a tiny fan and a small heatsink to help keep heat off the chip. There is no covering to focus the heat in a certain direction, nor are there any heatpipes to help take the heat toward the fan.
