2 cards different temps

[LitecoinRates]

Hi Folks,

I am running 2X AMD Radeon R270x with cgminer.

One runs at 72 degrees, the other at 83 degrees, always 10 more

Why is the second card 10 degrees higher? I have to run the fan full throttle to cool it which makes it noisy.

Thanks for looking.

its pretty normal. the display is on the 2nd card so its doing more work i assume you have them in crossfire so the 2nd card does the display work. run the pc with no side on it should help with cooling

It's not because the display card does more work.  The display card would actually run cooler then since mining (scrypt anyways) pretty much maxes out the card while basic renders for display are minimal work and actually cut the 100% throttle of mining.

The #1 card (the one in the top slot) is sucking in hot air from the back of the 2nd card.  If you swap the card positions you'll notice the cards will swap temp gradients.

Only way to fix that is put some good distance with risers.

Thanks both for the feedback. How do I remove the crossfire, just unplug the ribbon cable?
