The real issue is that you should see if any data is available about whether the fan starts up with only 7 volts of power. If that is not the case all other specs really are moot.
I would think it's probably better to avoid fans with a thermistor (temp control sensor) as they may lower the voltage of the fan to a level in which the fan never of rarely turns on.Quote:
(does this fan switch better in between speeds as the console heats up?)
Since the PS2 already varies the voltage going to the fan a temp sensor is largely not needed.
A fan with a position switch is a better idea for controlling fan speed as you can control it's speed.
A site such as silent PC may provide info on whether a fan starts at 7v or not.
If you plan to power the fan from a 12v location, then I guess you don't need to work about the 7v issue. I don't know about 12v power locations, so consult some chip install diagrams if that is the route you want to go.
