actually, it sorta can.     find the lowest reading sensor on the 
system, probably one on the mainboard...    use a manual thermometer to 
read the intake air temp and calculate the delta.

i think you'll find under normal operating conditions that delta is 
pretty constant if the server is under a reasonably consistent workload.
