Bump... I have figured out why my mhash/s is lowering on my second and 3rd card... They down clock them selves when I turn them on... I can only asume this is because of heat... So what do you guys use to keep your temps down? I hit 100c plus with all three cards on, and the middle and top cards hits 95 when I only have two running (bottom and middle or top is the same result)... Any suggestions are welcome, but my comp is in my room so using 190CFM fans in the GPU duct in the HAF X is not an option (I have tried
Have you considered going caseless? From what I have read, it's going to be tough keeping 3x5870s cool in a case, especially if they are close together. I have enough trouble with my 2x5850s in a case, and will be going caseless soon. I know, if they are in your room, you don't want a caseless mess, but it may be the best way to keep the cards cool. If you are handy with tools, I think it isn't that hard to build an open air case that is relatively tidy. I've built an aluminum frame that I might cover with some mesh screen, and I think the end result will look OK.
