Diamond HD5570 TemperaturesIn an HTPC setup temperatures can be an issue mostly due to the confined space and typical lack of cooling in the small cases. This could especially be a problem for high performing video cards. The design of Diamond's HD5570 includes more memory and a faster clock which will generate more heat.
When taking measurements the video card is first idled in 2D mode to obtain an idle temperature using GPU-Z.Then Furmark is used to stress the GPU and raise the card temperatures until they are steady. Temperatures are again recorded from GPU-Z under this stressed scenario. During testing the ambient temperature remained steady at 20.2°C.
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 it's been proved that 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.
The temperatures recorded for the Diamond HD5570 are recorded in the table below.
These temperatures are not on record-low scale, but I wouldn't be concerned about overheating during some long movie sessions. When we tested ATI's 5570 it measured at 35°C idle and 50°C under a load in a sdifferent hardware configuration. The idle numbers are close, but the performance under load is much different. Despite the marks being similar between tests the heat generation is much higher. I doubt the difference is due to case cooling since we're comparing a HAF 912 to CM Storm Sniper. But why do we have more heat at comparable performance even with the faster memory clock? Another indicator that something was not up to snuff with the card.
