MS1000 and MS2125 fan leads and CFM question

Stereo Junkie · Post by **Stereo Junkie** » Thu Jun 26, 2008 12:46 pm

Do the fan leads on the pcb's of the MS1000 and MS2125 have variable voltage over them or are they always on/off?

Thanks,

The fan output is a constant +12V when the amplifier is powered up.

Rolandk,
Big thanks!

Okay a follow up question then. How much CFM would need to keep a MS1000 and/or a MS2125 cool if inverted?

Thanks,

Just get one that you think is WAY to big and then buy another just like it. Should be good. Run 1 to push and 1 to pull.

mikelycka,

Good question! MS1000 probably in bridged at 3ohm on each side trying for ~1000 W. MS2125s in stereo at 4ohm for one around ~70 W and the other around ~150 W.

I can find some Sunon fans 60x60x38mm that move ~56CFM but they are anywhere between $10 and 25 bucks a pop.

Thanks,
