There has been a lot of talk about the e8400 temperature readings since this cpu came out. Many overclockers are readying irregular or high temps with these processors. If you are concerned about this, you are not alone.
The only real solution at this point in time is to wait for the first revision to come out. When will this be released, nobody knows. The amount of time it takes depends on how much of a problem Intel thinks this is.
The real question is how much of a problem is this? If you are not overclocking then it is not a problem at all. As long as you have your heat sink installed properly you won’t be having a problem with this issue
Keep in mind some motherboards are reading the chips better than others, check around and see how your motherboard is doing. It seems that Abit P35 boards are prone to the error. On the other hand Gigabyte P35 boards seem to be working fine with the e8400.
If you are a moderate overclocker, then this shouldn’t be a deal breaker. You will have to be very careful with your overclock to make sure you don’t fry your chip. If you don’t mind taking a little risk, feel free for a moderate overclock.
If you plan on doing as high as a oc as possible on the Intel e8400 cpu, this could definitely be a problem. There are other means to read the temperate of the processor, but you are playing with fire pushing the chip hard with faulty temperature readings from the chip.
Personally I would wait for the G0 type stepping that fixes this problem. I like the piece of mind of knowing everything is ok when I look up the temps. I am also a moderate overclocker and would like to push the chip to around 4ghz. That’s high enough where I would like to know what the temps are reading on the chip.
