While it is normal for the top card in a Crossfire situation to run several degrees warmer due to less airflow, it is not normal for a 7870 to run at 80°C under normal gaming circumstances. Improve your case airflow.

Well....I installed the sapphire trixx and could reduce the temp of the first gpu, but even changing the second too, only the first GPU use the trixx settings, any ideas?

If your 1st adapter is exactly on top of the other (pcie slots too near), then no matter the custom fan speed you use, it will always overheat because it sucks hot air directly from the second adapter during load.

If there is enough space between the two cards inside your pc case, and you have a good internal case airflow, then 90°+ C is too hot for the 1st and 80°+ C is too hot for the 2nd as well.

Leave automatic fan for casual pc use only.

Use msi afterburner to make a custom fan speed of 50-70% rpm, before launching a demanding/ stressful game, so as to maintain a temperature mark of up to ~78° C. Adjust fan speed accordingly and/ or case airflow.

Thx, my MSI config for fan control is changed to:

40º - 80%
50º - 90%
60º -  100%

now in game my 1st temp is 85-87º and my 2nd is 78-80º

Still too high, in my opinion.

Is the 1st adapter on top of the 2nd inside your pc ?
