In my M3 this fan uncouples when it cools down and barely spins, then couples when it gets hot, spins quickly and increases airflow through the radiator.
2. The clutch pedal was EXTREMELY soft.
As for the fan, it's supposed to work the same way the clutch fan in your M3 does. Fluid gets warm, thickens, causes fan to spin...cools down, fan stops spinning. You can get electric fans and make them fit with a bit of fabrication work, or you can just get another OE fan from a junkyard or off the Buy/Sell/Trade forums here on NICO. Sounds like the one in that car is done for.
The clutch pedal might be soft due to improper bleeding when that new master and slave cylinder was installed. Theres a damper box in the clutch system that makes it really tough to bleed...a semi-popular mod is to bypass the damn thing completely with some stainless hose. The clutch feel of a stock 240SX is moderately soft, IMO. I'm sure it won't be nearly as still as your M3.
BTW, if you don't mind saying, how much is the seller asking for the car?
Also, how 'bout some pictures of that M3?

Nice car, man!
