Only reason I noticed this so well is, my 2002 Nissan Frontier A/C does virtually nothing when I'm sitting at idle, 'cause the fan doesn't kick on at all. It sucks!

I know many cars do this, but the 8 does not - the fans are strictly controlled by coolant temps and are not automatically turned on with the AC Compressor.
I cannot recommend highly enough the Mazsport Cooling Fan Mod - I have had it for 1.5 years and it works great. While it will not actually increase your maximum cooling capacity, it will get the most out of it and will keep you average engine temperature much lower during normal operating conditions.

Getting the accessport means you can increase omp flow rates, which I consider far more important for engine longevity. You also get to adjust the radiator fans to kick on at any temp, with any speed you desire. So no need to cut into hoses and no need to be locked into one fan setting.

he also said best AND cheapest.
if you get this, then you've wasted your money if you get the AP for OMP rate increase. So you have to decide if you ever plan to get the AP for that statement to be valid.
Remember, the engine was designed to operate at temps higher than 190F. We only use the fan speed increase to treat a symptom, it doesn't resolve the problem, which is heat soak and overheating. Once the vehicle gets too hot, it can take a long to cool off. So we try to keep it away from that point to stave off problems. It doesn't increase the cooling capabilities of the vehicle, it just increases the buffer between "operating temp" and "overheating" by causing the vehicle to run cooler than designed. It will not increase engine life unless your car is getting overheated on a regular basis before the mod, and assuming the increased buffer is enough to keep the car from overheating afterwards. If you're in AZ or LV and overheat before, you're likely to overheat after as you're using the same exact fan/radiator before as after.
So like I said, OMP > Fan speed. AP gets you both. Plus power.

surprised you didn't say 'Plus power and economy.'

Cooling Fan 3 Relay
Have had the Mazsport Cooling mod for two weeks now. Everytime I pull into the driveway coming home from work (only 5 miles) my fans are blowing hard! I love it!!! It makes me confident that there was something messed up with one of the fan relays. I'll probably go have them tested just to see.
Rythmic, don't delay and pick one up now!
So can anyone confirm what the Cooling Fan 3 relay is for?
