In my Antec SX1040, I have my Asus K7V 600Mhz. board. I'm using the stock Antec Fans from both my SX1240 and SX1040 and getting decent Temps. Thats a total of 4 ea. 80mm Sleeve Bearing 34.0 CFM.
When I placed those same fans in my SX1240, I got highly elevated system temps. System was about 27C, and 44C Cpu temps.
I replaced them with 42 CFM Ball Bearing Sunons, as I returned the Antec Fans back into my SX1040. With the higher CFM Sunons, I'm getting a System Temp of 24C, and a CPU Temp of 36C, as I type this post. That equates to only 1C over room temp.
Seeing those System Temps fall, convinces me that High CFM, High Quality fans are doing a better job at cooling with Positive Case Pressure.
I would like to upgrade to the Panaflo H1's as my budget permits.
Also, I have found that most Antec Fans are rebadged Sunons. I found this by removing the Antec Fan stickers.
