I replaced my PSU fan with a Panflo L1A, just wondering how much CFM should the fan push, is the Panaflo good enough?

The air coming out is just about as hot as it was before after extended periods of use. But if I need to, I will refrain from using it extensively.

I replaced Antec PS fan with Panaflo L1A. No measurable or noticeable difference except it's quieter.

I found negative case pressure produced better temps in my Antec 1030, two rear case fans extracting, plus extracting PS fan. I considered just removing PS fan, but didn't want PS heat being sucked into case air.

If I were running positive case air pressure, I'd have tried just removed the PS fan without replacement.

I've modded the PSU's with Panaflo L1A's with no increase in case temps and maybe even a small decrease.

Bryan1129: check what the rating of your old PSU fan was. From the label you should be able to determine the model. Chances are, it's a Yate Loon fan, http://www.yateloon.com/. All three PSUs of my computers I checked are Yate Loon, a 200W AT one, and 250W and 300W modern ones also.

If the CFM is of your old fan wasn't much greater than the current Panaflo, then not to worry.
