Yes, 70 C is waaaaaaay too high. At those temps the BIOS/CPU would be thermal throttling ... intentionally lowering the clock speed and voltage of the CPU to keep it from burning out. It definitely sounds as though the stock HSF ... that is what your are using, right? ... is just not seated correctly. To reach 70 C at stock speeds just idling in the BIOS I'd wonder if there is an air gap between the HSF and the processor.
Have you tried resetting the HSF? Make sure you reapply the thermal grease.
I did reset the hsf. Im going to buy some more thermal grease since the thermal grease under the intel heatsink didn't seem to be enough.
Don't forget to somewhat thoroughly clean off whatever thermal bridging material is currently on the heat sink and processor before applying anything new. The "Heatsink Preparation" section in the
install instructions for Arctic Sliver has some suggestions about how to do the cleaning you might want to check out.
Did u remove sticker under heat sink. Maybe u have cheap PSupply. U might consider water cooling.
There was no sticker under the heatsink only three strips of thermal paste.
:? That sounds strange. Is this an Intel boxed retail E4300 or did you get it some other way? I always thought the heat sinks which came with Intel retail processors came with a thermal pad pre-applied. Supposedly the thermal pads are made with a paraffin wax. The wax melts once it gets hot and binds to the heat sink and processor heat spreader. But it sounds like your heatsink had something else on it. I'm not familiar with a heatsink coming with "strips" of thermal compound pre-applied. :?
