Review on Apevia CF4S-BK 80Mm 4Pin Molex + 3Pin Motherboard Black Case Fan - Connecting To Power Supply Or Motherboard by Jared Allred

As the title says, they are very quiet even at full load and I needed something to accommodate extra fan space for the pair of passive GPU coolers I had on some retro systems. However, it's disappointing how little airflow they have. Why? Well I still have the old Socket A platform and it has a heatsink where you can fit an 80mm fan. I was hoping to use one of the leftovers from this kit to cool down the XP 3200+ I had; Well, long story short, this thing just didn't have enough airflow to keep the CPU cool enough to get past Prime95 or something. However, it is still suitable for mounting on a case or GPU cooler. Unfortunately, this just means I need to look for something with more CFM for the sound level.
