Don't bother, those programs only cool the cpu when idle, and can affect performance when under load as well, but it'll never reduce load temps, i used them once way back in K6-2 days and found in some games it jerked about but with it off they did'nt, tried it back like 2yrs ago on my Athlon 1.2 and same, maybe those bugs are sorted. Also the temperature variation over time when going from such a low dle temp to a high temp and back can cause core fracture, especially with todays high speed hot cpus.
