I have three non-reference 5870s that I absolutely hate.  They are a dual-fan Gigabyte design (http://www.gigabyte.us/products/product-page.aspx?pid=3430#ov)

I cannot keep them cool.  They are well spaced, and each have a delta fan blowing down on them.  Cgminer tries to keep them at 75C.  One runs the fan at 0%, one at 67% and the other one can't keep up at 85% (at stock clocks).  I have tried reapplying thermal paste, etc.  

The heatsink and fan assembly are attached to the card by four screws surrounding the GPU.  Can I get aftermarket cooling solutions?  I would love to get a "reference" type cooler.

Is there a standard mounting system?  Or am I left in the dust because my card is non-reference?

Thoughts?

Dan

I have the same card, agree, cooling is shitty.
80-84C on core (depends if the windows is open) with a 80mm fan laid on exhausting hot air up, fan @ 85%

Let me know if you find anything, i have 2 of the VisionTek versions of that card, same thing, one runs cool as ice, the other one jumps all over the place.  I fucking hate the cooler design.  But hey, I got them for $100 each so I guess it's a fair trade off.

I had my XFX fan fail on me and they just sent me a cooler from a dead card they had. Very nice.
