I see no cooling effect
1) Make sure your system is idle when VCool is not running: Software coolers will have no effect on busy systems. Use the task manager (W2K) or Wintop (W98) to see if there are any threads eating up time (e.g. SETI@home).
2) Start VCool and set the NB Cool Bit but deactivate the loop. Check again that your system is still idle.
3) Still no temperature drop? Then enable the idle loop. When you check utilization you should see that VCool eats up most of the CPU time now.
On newer systems the Halt Detect PCI option is often required to achieve cooling. You can configure VCool to use this option instead of the cool bit or even both. NOTE: In some cases the idle loop might actually increase the temperature with Halt Detect enabled, so try try deactivating the loop.
If you still don't see any cooling effect VCool doesn't work on your system. Sorry. It would be nice if you could email me your system specs.
PS: Make sure the the temperature display is actually being updated
