Is running your CPU close to 100% most of the time really that dangerous?

So I have not been using my system a lot lately so I decided to start running Folding@Home on my PC. I have it running almost 24H a day most of the days. The Folding@Home client uses between 70 and 80 percent of my CPU. Whenever I start running whatever other program my system goes up to 95ish percent. Is it really that dangerous? I know is by no means ideal but is it so bad that I should stop this immediately or is it ok? My system is an i3 4150 so it is not a high powered CPU running extremely hot but I am kind of worried since I am using the stock cooler and the max temp is about 71 degrees Celcius (when I am using my PC for something else and my CPU is running at 98% load, so it is not all the time running at such high tempertures) and when the PC is only running Folding@Home the temps decrease a bit.

if your temps are ok it should be fine

No worries. As long as you aren't going above 85 degrees you are fine.

As long as your temperature is okay, you're in the clear.

I would just run f@h on your idle time. We don't know how long your cpu will last to begin with so i can't tell you the decrease in lifetime. You will probably upgrade before it dies. 70c is about what i get and i boinc when i sleep. Nothing is free. I exexpect to upgupgrade in 3 years and for motherboard and cpu to last as long or longer.

I was in the same exact boat is you. I just got the cooler master 212 evo for my i3 4160 and my temps never go about 36 degrees Celsius while folding. But if  does bother you just enable it while the system is at idle.
