Your stress testing program and your temp program should be separate. They call on different parts of the PC (so to speak). If your trying to max out using prime95 I would not want it doing temp / voltage monitoring.
My OC tool suite consist of CPU-Z, PRIME95 Priority 8-10, and Hardware monitor. Some may question CPU-Z I like to monitor the FSB multiplier changes if any are taking place. Also good to see to see if AI overclockers actually work and what is being changed. MEM, CPU.
Throw in a GPU torture test like ATItool and your really working that PC.
