2 x 6870 Temp Issues/Crashing

For you who want to jump right in - here's my afterburner:



Case: Silverstone RV-02. GPU's are vertical in slots 1 and 3, with 2 pci slots of space in between them.

MoBo: Asus p8P67 WS Edition

GPU's: MSI Twin Frozr II R6870's.

The GPU in slot 3 is the overclocked version that is clocked at 920mhz over 900. Newegg shipped me the OC version on accident - what should I do?

Monitors: 2 x 1080p >> GPU1 and 1 x 1080p monitor >> GPU2.

Load: Very little load. Just internet browsing - no active video's besides maybe a song on youtube with just a pic.


-My temps, clocks, and fan speeds are drastically different
-Sometimes a GPU will freeze or go all black? Hasn't done this recently, however.
-Crossfire is disabled for multiple monitors.

Is this normal?

When I put my hand in the case everything feels cool. All fans are spinning. Lots of airflow...


Any suggestions?

The difference in temp can be explained by location the upper card is in the heat from the lower one. I see nothing wrong with those reports. Check the temps when under load!

But the bottom card is hotter and they are vertical with excellent airflow...

Same cooler both cards? GPU1 more load 52% higher temp, normal! GPU2 overclocked version less load 14% lower temp possible better cooler! Which one has the cooler facing the other card? I would think GPU 1

GPU 1 cooler is facing GPU2? like most 2x GPU setups. Then that means that the GPU fan is sucking hot air from the other GPU not blowing on it!
