nVidia SLI temp difference between cards
- Thread starter cyber69
- Start date
The primary card has more work to do, and will have a higher GPU temperature. This is exacerbated if the secondary card is restricting airflow to the primary card (If the cards are in adjacent slots). It's the load temps you should be looking at though. If the load temps are very high you might want to increase airflow to the cards (A side fan could help here).

Yeah, it's normal. I have around 15-20c difference between my crossfire cards. The top card works harder, and heat rises, so some of the heat from the lower card warms up the top one as well. Sometimes this evens out during heavy load.
Just check your top card doesn't get hotter than 80-90c during load, and you'll be fine.

There's a few. Check out Heaven, Furmark, and OCCT (mostly known for it's cpu functions, but also great for GPU testing).
Many of these benchmarks will produce temperatures higher than any game will produce, as they push the card to unrealistic levels...... so lots of people are still using Crysis warhead for it's benchmark, as its considered the most demanding program that uses your system in a realistic way.
