I'm currently using speedfan, but I want something better for taking CPU and GPU temps.. Any suggestions?
Give HWMonitor a go. http://www.cpuid.com/hwmonitor.php I have run it in conjunction with coretemp and it gives the same results, however it also provides accurate fan speeds, GPU temps, HD Temps and ambient temps (Case and CPU). I have found this to be the best alround and also the least known about.
