I recently fried two of my exhaust fans (cpu) i had on my box. Luckily i have more on hand. Now to the puzzle.

When my old exhaust fans were in use, they pulled out a lot more air than my current fans. When the old exhaust fans and circulation fan were on, and with the intake fan both on/off, the temperature would rise causing me to turn off the intake (didn't mattter if was on/off, same result) and circ for a period of time till the temps lowered.
Now when i installed my new fans they pulled out less air. I kept the intake/circ fan as the same with the old exhaust timing, and noticed that when the intake/circ was on, the temp would lower...even lower than the old fan set-up. But with the intake/circ fan off, the temperature would rise.
I'm not complaining since i can keep circulating the air at a lower temp than previous...i'm just puzzled why this occurs.

If the old fans were on their way out they probably weren't turning up to speed
thus not moving the rated airflow...

WAS MOSE'S REALLY SPEAKING TO A BURNING BUSH???
OR WAS IT ONLY SMOKING???

no that couldn't be it. When i put my hand over the fan before i fried it, i could feel more air than the new ones. Oh well, i've just decided to thank the MJ spirits
