I have been reading on various other forums about speculation of non-reference GPU cooling designs should have specific heat pipes and heat sink direction orientation to help GPU cooling. For an aftermarket cooler, some people argued with heat sinks going parallel to the air flow of the bottom AP fans, will help cooling better?? Is this just pure speculation? Or so marginal that it's silly? I'm hoping to order a FT05 soon and go completely air again with SLI 970s. I'm conflicted between aftermarket coolers (MSI vs Gigabyte) because the reference 970 by Nvidia is expensive ($380 USD each!!) or aftermarket reference coolers are plastic and loud. Some clarification would really be appreciated before I place my orders.
