At 50dB is the Asus DDR3 card and the EVGA card – the former continuing to use its high fan speeds, and the latter having to rev up to make up for its smaller single-slot cooler. It’s under load that the story takes a turn for the most interesting. Its higher fan speeds means that it even idles at a pretty high speed, making it the second-loudest thing after the GTX 295.

The Asus DDR3 card however is quite distinguishable and is at the bottom of our charts. Active and passively cooled cards are nearly indistinguishable at this point. They all run up against the ambient noise generated by the rest of the computer. This makes it cooler, but as we’ll see it makes it louder too.Īt idle, there’s not much of a story for the GDDR5 cards. For what the GT 240 lacks in performance, it can certainly make up for in temperatures.Īs for the DDR3 card, in spite of having the same cooler Asus has opted to run the fan at a higher speed. The EVGA card meanwhile is 4C cooler than the GT 220, and still 15C cooler than the 4670 in spite of the use of similar single-slot coolers. Our stock Asus card is some 8C cooler than our GT 220, and 19C cooler than the Radeon 4670. Ignoring the DDR3 card for a second, both the Asus and EVGA cards are quite cool.

Load temperatures tell us a somewhat different story however. The double-wide cooler on the Asus cards looks to be good for a couple more degrees than the single-wide cooler on the EVGA card is. These would probably make fair HTPC cards, but the GT 220 should be a bit less power hungry and cooler.Īll of these cards push the limits of what’s practical for idle temperatures, although the Radeon 5850 is finally dethroned here by 2 of our GT 240 cards. Between the GT 240 cards themselves, even with the different in RAM types, they’re all within 2W of each other. The only thing that’s significantly lower is the otherwise anemic 9500 GT while the Radeon 4670 is in a dead-heat.

Under load, these cards are still near the top of our charts. The lack of true idling for the DDR3 card will have some ramifications later. Unfortunately our DDR3 GT 240 refused to (or is simply not programmed to) idle, meaning that it comes in a good 8W higher than the GDDR5 versions of the cards. As an added bonus, with the significantly different designs of the Asus and EVGA cards, we have a chance to see the difference in performance for their respective coolers.ĭue to some unrelated issues we don’t have the GT 220 in these charts, leaving the GDDR5 GT 240 as our least power-hungry card when it comes to idling. With an idle power draw of 9W, and a load power draw of only 70W, the GT 240 should fare fairly well here.
