Not to mention that if one goes out, the other one is still pumping away.
to me this is infinitely more important than the extra power/flow from 2 series pumps
at PDXLAN, this guy had a couple 6800Ultra SLI cards on a single pump loop and the pump stopped or burned out or something
MELTED his 6800 cards cuz teh rig doesn't shut off if the gpu gets too hot (only cpu lol)
well, CPU Killer replaced his 6800's with a then-brand-new 7800GTX right on the spot just cuz he felt bad (wasn't even Killer's fault in any way.... happens ya know?)
but it should be a lesson...redundancy is nice (which is why we like RAID-1 for important data)
ps: that same PDXLAN, a kid flew in with his rig, and it got bounced so hard that the cpu heatsink and retention crap got ripped right off his Abit IC7 Pentium4 board....there was no place to get replacements of any kind at night and even the next day would be a hassle having to drove 40 miles down to Wilsonville to the only real store (Fry's) in PDX....so I called CPU Killer over to see what he could do...and CPU Killer just modded his case and installed a watercooling setup RIGHT THERE ON THE SPOT...and charged him NOTHING.
if you guys ever wonder why I promote Danger Den so much...it is because there's no freakin way anyone could EVER beat that kind of service...never in my life have I seen so much at once
