Well folks the decision is MADE! After checking my AsusProbe temp logs... I've determined that actually running a Totally independant fan exhaust for your HCore IS physically better for temps... that extra heat added, as someone put it, DOES matter! At least in my case... I checked back over a few days/weeks from when I had the triangle and I notice that the case temp and the idle/max loads of my CPU were VERY CLOSE! Pre 172mm I was getting around a 3-6C temp diff between Case and CPU idle and max.... With the 172mm I'm seeing more like 6-8 Idle Max, which isn't too bad, but I'll stick with as LOW as I can get!
Oh BTW- The 172mm Pic is with the XP2000 at 1720mhz@1.792Vcore
The 120mmTriangle is XP1600 at 1806@1.774Vcore
The hotter 1600+ putting out MORE max wattage still runs cooler than the less wattaged XP2000 when using the Triangle! Case isolation DOES matter folks, Least I've SEEN the results and about about to switch back... Anyone wanna buy a 172mm Comair Rotron 300CFM@4500RPM 12volts? haha
