Question about power supply 'Amp' ratings (rated current)

[tjasinto]

Hi all. I have a Powermac MDD Dual 867 Mhz G4 'the wind tunnel macs'..LOL

I'm replacing the 2 power supply fans.

I got a hold of 3 different thermaltake fans. All of them are 60x60x25mm.

One of them, an old (approx 4 years old) Thermaltake Volcano 5 has an amp rating of 0.19 amp.

The other 2 fans have rated currents of 0.17 and 0.32 amps. These 2 fans are brand new.

I know for sure that the Volcano 5 would work with my power supply but like I said it's old and it probably has anohter year of life in it.

Which fans should I use in my power supply? How does the different current ratings affect my decision if they have any affect at all..

Thanks

that little of a diff in amp ratings aint gonna matter, unless of course, you've already got 100's of other high-amperage devices suckin lotsa juice from the psu........

However, generally, the higher the amps, the faster the fan can run, and therefore probably be capable of moving a bit more air, depending on the overall design. Also generally, the more air it moves, the more noise the fan will make......
