Well, I did contact Asus and they did say they would replace it as long as I sent off the original.
The thing is, that when it came for me to do that, I could not find the original fan???
I have now found it, but, Im also using a Zalman anyway so its kind of not worth worrying about?
I dont know though cos the 6600GTs are in a Ca19-SLI Board and while they are a Zalman and an IceQ Cooler, they are fine in there.
The 7600GTs are in the A8N-SLI and again, with the Zalman NB cooler and the both cards having Zalman VGA Coolers, it needs the 2 PCI slot gap to fit them in, so they are snug.
And the Foxconn only has the 1 PCI slot gap, however the 7800GTX Cards are running stock ( Thin ) cooling and therefore they too are snug.
If I was to go back to the A8N with the 7800GTX Cards, this would also mean that I will need to get different coolers for the 7600GTs to put them into the Foxconn.
I dont like the foxconn though... At first it could not see 4GB and now its seeing 3.9GB and Windows sees 3.7 ( and Im on 64Bit ) - The Latest BIOS has helped, but not fully.
