Any number of reasons, fan shape, proximity to the vents.How is that even possible?The Jamma Nation X fan was as loud as my original one.
Ended up using a Gelid Silent 6 fan for a fraction of the price of a 612FL.
I don't make stuff up and don't like having to replace parts.
Silent 6 is way quieter than that cheap debranded JNX one when fit into a cps2.
That said the JNX moves more air and would be better suited to inside a cab.
Bit loud for my consolized cps2.
