Really, go eff yourself liar. ENJOY THE UNEMPLOYMENT LINE WHEN BFL goes BANKRUPT. How do you expect to cool 6 asic chips with one fan? The 7990 has two chips and requires three fans to keep them at 90c when under full load. STFU you scamming bastard.
Yep. My 6800 series dual gpu cards with a vapor pipe engineered by a multi billion dollar company run at 100C when mining. Two fans will not keep them cool on a hot summer day and that's just two chips.
BFL is a long con only interested in stealing money from unsuspecting noobs.
