Yeah my venemous-X with just one fan gets up to 90C in small FFT prime, with 5 ghz and 1.45v load going through the thing.
And TRUE black with Ven-X mount fares even worse, even though the mount is so secure with the TRUE that it doesn't swivel one bit...(the Ven-X swivels but temps are lower).

Even a 190cfm Delta won't help, because it reaches 80C within 5 seconds...
