[Amps] SS amps watercooling - was PowerGenius XL

[Joe]

I was even thinking of one of these crazy yet cheap server power supplies.

I got one here that can make 13.2 volts at 140 amps! Yeah. wow, BUT the 
thing is small with two tiny screaming muffin fans, for cooling, even 
tho there are two, and they are screaming loud! Yet they don't move crap 
for air. Holding an incense stick burning near the air vents and you can 
determine what way the air flow is. Barely, if it is moving 1 cfm I'd be 
amazed.

Hmmm wonder what it would go in a gallon paint can of transformer oil?

Sure would make it useable. Right now unless you mount it in a different 
room forget hearing anything.
