Is 70c too hot for CPU when gaming?

I have an Intel i5-3470 3.20GHz CPU with a stock cooler. When i play game like Heroes and Generals, it goes up to 72c. When my PC is idle, it goes around 30 and 40 degrees. Is it a safe temperature or i should upgrade coolers and changing thermal paste? I also wonder if a better psu like 400w or 500w can reduce heat? (Sorry for my bad english)

    No need to upgrade the cooler or change PSU those temps are good and perfectly safe.

  2. 70-80c is normal range for a CPU under full load. Only worry about temps over 80c.

    PSU has nothing to do with CPU temperature.

  3. I think just because they are safe doesnt mean your CPU is not degrading faster than a CPU that is cooler. There are better performing heat sinks out there for under 40 dollars that will perform pretty close to any corsair liquid cooler. As just a note check the CPU fan and make sure it isnt stuffed up with dust
