Koolance PC2-C Fan Question

[aceman817]

i was thinking of upgrading the stock fans on my pc2-c with some quieter ones. the standard ones push 28cfm @ like 33db (approx. couldn't get accurate number) and i was thinking of getting like a stealth fan which pushes 27cfm @ only 21db. this sounded like the best replacement to me as the panaflos are about the same in noise and don't push as mush air. has anyone upgraded their fans on this or any other koolance case? if so, which ones did you use? also, i notice that the stock fans only have two wires like the panaflos while the connectors on the panel have the usual 3 full pins. will getting fans with all 3 wires make a difference? isn't the extra wire for like monitoring or something? any input is greatly appreciated!

Actually, I'd take said Panaflos over the Stealths. While they are rated at the same noise level, decibel ratings are subjective, and the Panaflo L1As are actually quieter. Plus you get unsurpassed reliability and save a few bucks with the L1As.
The third wire is for monitoring RPMs- not essential, especially for case fans.

what are the L1As rated at? i though the cfm on them was much less.
