I'm currently using this software...is it reliable....??
and is this software actually measure the CPU temperature???
because my PC is often hibernated by this software.....
I like to know the actual safe temperature for CPU...can somebody help me??
I also want to upgrade the cooling system on my PC...is it necessary....??
currently I'm only using pre-installed CPU fan....and GPU fan only....
I'm using CoreTemp right now. I don't think it's accurate in the display of the clock speed of the processor (even under load, such as having 5 instances of batch converting WAV files to MP3, I still see 0.2 for 200 MHz - I'd expect that when idling, not with 60% CPU usage). As to the accuracy of the temps, that I don't know, though they do make sense (I've seen them get to just shy of 70C during that conversion).
38 to 45 for idling is only slightly high and is what I generally get. When under load, 70 is okay, though a bit high. When temps start getting pushing 80, you should be concerned. Usually, processors reduce their clocks when heat gets too high to protect themselves.
CoreTemp is accurate for temperatures - as are RealTemp and CPUID's Hardware Monitor (recommended). You can get one of the others to crosscheck if you'd like.
Use CPUID's CPU-z to watch frequency and other pieces of information.
Your temps are NOT a problem. You can drive your cpu at 100% using Prime95 Stress Test, and CPUID's Hardware Monitor to watch the temperatures. As long as the core temps level off before hitting 80C, you're OK. If you hit 80C, a better cooler and/or case may be needed for long-lasting 24/7 use. Nothing you run will drive your cpu as hard as this test.
