Just because the "red Zone" is upwards of 80 does not not mean that it is OK to run it that hot. What I am getting at is sure 55 is fine for a little while but extended periods? I still say that is pretty high. He said it runs 55 at idle, under load it could easily be reaching 65+ To me that is just asking for a shorter life span.
Rock on
With all due respect, if you're going to take the 30 seconds to Quote/contradict what I said, then do us both the favor and take
35 seconds to make sure you're doing it correctly. Kthx.
I never said it was OK for a CPU to run upwards of 80*C and see no damage to them, simply that older ones 'could' operate up to around that temp. My car's engine CAN hit 6700 RPM for a short time if necessary...does that mean it will sustain it for extended periods of time with no damage...of course not.
What I said was "55*C is fine, temp-wise" (Read as: 55*C is fine, you will not harm the CPU").

Cooler is better, but that temp is acceptable.
CPU's frequently operate in the 50+*C range. In fact, it's probably more common for them to do so than it is for them to not do so. Not everyone builds their own PC, places fans for optimum flow, uses high-performance third-party coolers, or positions their cases away from heating vents. The majority of pre-built systems focus on quietness then they do cool-temps, and honestly, the general public could probably care less how hot their CPU runs, just that it *does* run. Part of the reason CPUs will auto-shutdown these days to protect themselves.
As far as shorter life-spans, a new, average CPU is designed to last 11+ years under normal use. Let's be liberal and say that a CPU running at 55*C Idle will take 25% of that suspected life, then round to keep whole numbers; you're still looking at +/- 8 years of CPU life.
