60 degree idle temps harmful(not OC'ed)

[smartkid95]

I'm concerned about my intel celeron which isn't overclocked running consistenly at 60 to 70 degrees for up to 10 hours a day up to7 days a week. I like the silent factor of the pc but I think that thats why it runs so hot there isnt a fan on the processor heatsink the fan is on the back of the computer the fan won't turn on until the cpu gets to 70 degrees. this Is 3 questions in one is this dangerous to the cpu, do I need to put a fan on it or possibly a bigger heatsink, or change the fan settings. the form factor is micro atx in a horizontal case not overclocked stock speed.

thanks in advance.

if you would like lower temps, get a fan. it's not really dangerous but high temps lower performance and life. higher temps would cause damage.

There should be adjustable settings in the BIOS to make the fan come on sooner.

I have a small aluminum heatsink on it how much do you think a small fan would improve it

Substantially.
