it may be completely normal, but if your car never did this before, do one quick check. if one of your electric cooling fans goes bad, the remaining one will have to work overtime, i.e. after the car shuts down. to check your fans, start the engine and turn on the a/c full cold. pop the hood and look at both fans, with the a/c on both should be running, if one is out, there is a problem. the first one to go is usually the flat one on the left. if either one is off, turn off the engine and jumper the fan to see if its bad. if you dont have a/c you can just jumper each fan to check the motors and rule that out. hope this helps.
The small fan that you speak of on 4th gens is the A/C condenser fan. It comes on only when the air conditioning is running. The other fan (the big one) is
exclusively for lowering the temp of the coolant; likewise the small one is
exclusively for the condenser unit. One could drive all day with the A/C off and the small fan will never come on. It is exclusive to the condenser and will not come on under any other circumstances. The larger fan does all the engine cooling. If your A/C condenser fan does not come on when the air conditioning is engaged, use a 90-93 Integra condenser fan. It is identical to the 90-93 Accord fan and is usually cheaper at a salvage yard. How do I know all this crap? I've replaced both of mine
twice.
