70 Celsius too high under full load?

Hello, I have an asus motherboard w/ a core 2 duo 3ghz.
Idle temps for cpu= 41 C
idle temp for mobo= 32 C
CPU under full load (prime95) = 70 C


Under full load, motherboard stays same, but the cpu goes up to 70 C.

is that normal? I have arctic silver applied with the stock heatsink/fan.

Thanks for any input

E8400?

I regard 70 C. as right on the edge of "too high". OTOH, there's little in the line of real world applications that will load both cores 100% and drive the temps up.

Having said that, do not OC until you have better cooling.

yes, it is an e8400

Also, would it be normal to receive different temps on a different mobo?

I had this processor installed on a different motherboard, and it was about 10 degrees cooler with the same heatsink/fan.

Thanks for the quick response, by the way

what do u use to see the temps? check again with everest.

IMO is good, the problem coul be if the temp of the processor is more that 100, but inclusive mt 955 with oc @ 3.8GHz stay in under 80.

I view 70C as my upper limit, with 65C being more reasonable. And again, only for short spurts. I'd look to improve your cooling a little bit.
