Does not matter which way air blows. What matter is CFM - cubic feet per minute. IOW all fans must move air in the same direction across the chassis.
In a 70 degree room that computer should be perfectly happy even without a fan. Fan is necessary so that the system also works happy in a 100 degree room.
93 degrees? What is that measuring? CPU? Then that is 93 degree C. Important is to know what the max CPU temperature is. But I bet that 93 is above manufacturer's specification.
CPU temperature in a 70 degree room must be so low that when room (and CPU) temperature increases 20 degree C, then CPU is still below maximum temperature.
Chassis fan should not be a solution. With the case open, what is CPU temperature? Open case temperature should be same with or without chassis fans.
What is the CPU heatsink fan rated for in 'degrees C per watt'. Doing that calculation, you know what CPU temperature should be. Does that calculated numbers agree with measured? If not (probably not), then you know where fault lies.
Intel or AMD CPU? If Intel, the heatsink could have become completely disattached. CPU would simply adjust so that CPU damage does not occur.
What would a second chassis fan do? Lowers chassis and CPU temperature (at best) only single digit degrees. At most, one chassis fan means temperature inside the chassis increase less than 10 degrees above room temperature. But again, I suspect your measurements are in degrees C; not F.
What is temperature actually measuring? Northbridge? Where temperature is being measured is where to start looking for a failure. Although not sure what your numbers actually are, those numbers are not acceptable for any typically measured location.
