So here we'll have a look at GPU temperatures. First up, IDLE (desktop) temperatures.
IDLE temperatures are always a tiny bit tricky to read out as Windows Aero could have an affect on this. Overall anything below 50 Degrees C is considered okay, anything below 40 Degrees C is very nice. We threw in some cards at random that we recently have tested in the above chart.
But what happens when we are gaming? We fire off an intense game-like application at the graphics cards and note down the highest temperature from either one of the GPUs. The GPU with the least airflow will run the most hot of course.
So with the two cards fully stressed and close to each other as just explained we kept monitoring temperatures and noted down the GPU that got the most hot, there's was definitely an increase in the GPU temperature on the upper graphics card that lacks the most airflow, it normalized at 89/90 Degrees C which quite honestly is a lot.
Obviously with extra GPUs in your PC, please make sure your PC is well ventilated at all times, this will seriously help you on the overall GPU temperatures.
PowerColor Radeon HD 7850 SCS3 review We test and review the PowerColor Radeon HD 7850 SCS3 today. This stock clocked Radeon HD 7850 is cooled passively, meaning it has no fans tool it down. That also means it's rather silent as it does not make any noise. But what about temperatures then you must be wondering ?
Gigabyte Radeon HD 7790 2GB OC review We test and review the Gigabyte Radeon HD 7790 2GB OC edition, also known under SKU code GV-R7790OC-2GD. We benchmark the product incl FCAT Frametimes. The new graphics card is intended to boost a little more performance into entry-level gaming. The Gigabyte HD7790 OC 2GB clocks in at 1075 MHz on the boost engine, packed with totally silent custom cooling.
MSI Radeon HD 7790 TurboDuo OC review We test and review the MSI Radeon HD 7790 OC edition, also known under SKU code R7790-1GD5-OC incl FCAT Frametimes. The new graphics card is intended to boost a little more performance into entry-level gaming.
Radeon HD 7990 review We review the new AMD Radeon HD 7990 including FCAT frametime measurements. The dual GPU product that you guys learned to know under codename Malta finally is released. AMD it doing it in style, two fully equipped Tahiti XT2 GPUs versus good yet silent cooling. In this review we'll look at the product, the architecture, the benchmarks, including frametime based FCAT measurements. Head on over towards our AMD Radeon HD 7990.
