Released June, 2008

We can clearly see that the second GPU runs cooler under load, whether this is because load distribution or design of the cooler remains unknown.

When the top cooling assembly with the fan is removed, one big heatsink remains which looks very much like a Thermalright product.

I'm using a 750W PSU and it seems to be handling the GPU just fine. It may be a little excessive but it works.
