GIGABYTE GeForce GT240 Temperatures
Benchmark tests are always nice, so long as you care about comparing one product to another. But when you're an overclocker, or merely a 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 the NVIDIA GeForce Video Card, which gives detailed instruction on how to tweak a GeForce graphics card for better performance. Of course, not every video card has the 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.
FurMark does do two things extremely well: drive the thermal output of any graphics processor higher than any other application of video game, and it does so with consistency every time. While FurMark is not a true benchmark tool for comparing video cards, it would still work very well to compare one product against itself at different stages. FurMark would be very useful for comparing the same GPU against itself using different drivers or clock speeds, of testing the stability of a GPU as it raises the temperatures higher than any program. But in the end, it's a rather limited tool.
Starting with an ambient temperature of 22°C, I used GPU-Z to measure an idle temperature of 32°C for the GIGABYTE GV-N240D5-512I. The test system is an "open" chassis so internal case temperature was not a concern. After running FurMark 1.7.0 for 15 minutes, the load temperature stabilized at 60°C. This temperature is very low compared to NVIDIA's high-end cards, where load temperatures in the mid-90s are not uncommon! It's also 6 degrees lower than the identically-spec'd ASUS ENGT240 GDDR5, so GIGABYTE's giant fan is doing its work. This is a good thing for small form factor and HTPC systems, because although the largish fan is very quiet even at full load, the card's cooler expels all its heated air into your case.
