I have a rig with 3 x 5850s installed. When they're mining, the temperature peak 92-93'C on one of the cards. One of them peak at 82'C and the other one 72'C.
Clock settings & temps
Adapter 0= 775Mhz core, 900Mhz memory | 92'C
Adapter 1= 900Mhz core, 900Mhz memory | 72'C
Adapter 2= 875Mhz core, 900Mhz memory | 82'C
I reapplied thermal paste on the GPUs with Arctic Silver 5 4 days ago but the temps don't seem they've improve much. I am worried that the temp is rising over 90'C. I noticed that some ppl underclock memory down to about 300Mhz.
If I do that, would it improve the gpu temp much?
I can't underclock at the moment yet because I am running catalyst 11.5 and it won't let me set it under 900Mhz. I've heard 11.6 would allow me to underclock but I'd like to hear your opinion first.
The rig is running upright atm 90mm fan has been fitted to blow cool air towards the GPUs from the side.

I have looked around the board but couldn't find a specific answer, so if you have any suggestion or advice it would be greatly appreciated. Or if you can share a link with a possible solution, that would be great too.
Thanks in advance!http://C:\Users\Ei\Desktop\IMG_0245.JPG
