Glad your PS is sorted out. What was the issue?

Regarding the fan, I've only ever had one go bad. It made nasty-loud whirring sound and was pretty much frozen stuck solid no matter what temperature the engine was at, but I don't think it was overheating - but I also think the owner never drove it hard with that loud whirring noise (if I recall correctly - it was a number of years back). We replaced the fan's clutch assembly (moved the blades from one to the other), and it fixed the whirring noise.

Is your oem fan shroud still in place? How about the thermostat - is that new? ...and is it oem-spec?

Reminder: No one should ever be doing work on the Mkiv Supra Turbo's powertrain without a copy of the Toyota Supra Repair Manuals (TSRMs). I'm sure there's a test for the fan in the TSRM, as well as a complete diagnostic procedure for overheating.
