Hypothetically speaking, what would happen if one were to insert a CPU (namely a mPGA478 Celeron) into the socket while the system is powered on?

Just curious as I almost did this today by mistake....
 
The heatsink retention bracket was broken (as seems to happen often with P4s) and I had taken the CPU out to see if it looked damaged at all (not that you'd necessarily be able to see any damage). While it was out, we decided to turn the system on to see if the case fan was blowing as it should. This is one of those Dell cases which has a passive heatsink on the CPU, and a green plastic duct that comes down over the heatsink so that the 80mm rear case fan provides the CPU's airflow. The fan was hardly blowing much air at all, we discovered.

It's probably temperature controlled, so with no CPU creating heat, it's not going to provide airflow.
