CPU Fan Control Program Request

I have an IBM Netvista Socket 478 motherboard from an 8303 42U model PC (FRU
PN 02R4084). It has been flash upgraded to the latest firmware. In the BIOS
setup utility, it has a Legacy Fan setting with 3 options: ON=fan on all the
time, QUIET= fan runs at a much reduced rate, NORMAL=turns the CPU fan on
when the temp crosses some predetermined threshold. The good news is, the PC
is extremely quiet when in NORMAL mode. The bad news is, when in NORMAL,
whatever controls the CPU fan allows the temp to get into the high 50's (deg
C), then kicks on the fan and cools it to around 35 deg C in a about a
minute. It is bizarre, and works somewhat randomly, and I don't trust it.
So, knowing the outstanding cooling capacity of the heatsink and fan, I
would like a program that will monitor the CPU temp, then allow me to
control the fan to maintain a certain temperature range. I can run the fan
up and down manually with a freeware program called SpeedFan, but it does
not allow any scripting. Anyone got any ideas?

As a follow up, I thought I'd post that SpeedFan does indeed have a built-in
utility to control fan speed and regulate temperature to a desired setpoint.
The program works very well, I might add.
