what is the best hardware monitor temperature for cpu, vga, hdd
There HWmonitor and speed fan. Those are the 2 that i can think off the top of my head that see temps from all locations.
For Hardware specific temp programs,
Real temp (if calibrated, can be the best program to watch cpu temps that i know of)
EVGA Precision (for EVGA card temps, fans, and overclocking)
Nvida's and ATI's own driver control center. (at least i think ati catalyst also show temps like nvidia's does. been to long scene i used them)
List goes on.
