I went to Micro Center and returned the dud Bifenix fan. Picked up the Corsair AF-140 for exhaust and tidied things a a bit more. Nice sturdy fan, replaced with the white ring, rubber corners and close to 1000 RPM of stock Fractals.
Ambient 25C. Real Temp temps at idle: 33-25-28-32 +/- one or two degrees as it fluctuates. @7v it's pretty much the same. Was feeling a little disappointed with HR-02 Macho until I ran Prime95 Blended torture test. Temps were 55-54-58-59 with ambient around 27C. When I had the side open I tightened the Macho a bit more. Running @stock until I get GPU back.
Did a comparison of the two fans. Missing from Corsair's spec is bearing type. Anyone know what it uses?
Finished for now until My GPU RMA arrives.Bitfenix
