How sad...AMD die-hards are grasping at straws here.
The hype around this chip has caused every idiot who knows how to get into BIOS to try overclocking to 4.0ghz+, and people are burning chips because they dont know what they are doing with voltages.
Great chip. Best $189 I've spent in a while.

I am a big AMD diehard, so I'm going to lay it on the line.
Nobody makes a sensor, and reader combo that works, without having some type of calibration.
No desktop has a method to calibrate it's sensors.
If you think your computer is giving accurate temps, you are sadly mistaken.
On a single core chip, there will be huge variations in diferent parts of the chip. Dual cores just multiply those variations.
If you want to know how hot your chip is, run F@H. If it cant complete a work order, it's too hot. If it always completes, it's running nice and cool.
Endyn is right. Hot spot are in different areas. Later steppings help those hotspots along with other issues such as errata.
F@H is a good way to test it. Sois Prime95. If you can run Prime95 for 8+ hours(mine was about 11 hours then I stopped) can be assured your CPU is not over heating. I use 2 programs, a thermal sensor on my heatsink and the BIOS. And so far my CPU stays at 50-55c when under load with Prime95 even after 10 hours.
But in comparison to single cores having a dual/quad run as cool or cooler is amazing. But thats the amazing thing about technology. It gets smaller allowing you to add more and do the same thing only faster and better.
From a consumer point of view the chip doesn't have issues.
However, from a overclocker's view, the malfunctioning temperature sensor is an issue.
It's not a show-stopper, but it is annoying and lower the value of the chip to OCers, than and that there is less overhead in the higher clocked chips.
I returned my 8400 today and the guy at the store said more than half of the 8400 chips where being returned because of heat problems. Damn Intel for selling defective chips to their customers and trying to pretend there is nothing wrong. Money, Money, Money!!! is all they care about.
Dont buy the 8400 wait for the Next stepping!!!!!!!!!!!!!!!!!!!!
This sounds like the rant of an AMD mole. More than 1/2? What a joke. I can't believe people actually lend credibility to posts like this by responding with logic.

TC prove that the Wolfdale sensor is the one at fault here? I can just as easily say it is the software that is messed up.
Nothing I have seen in any of the multitude of threads has indicated it is the problem of the processor thermal sensor. I think you are spreading FUD. My opinion.
I've read most of this thread and would like to add my experience with the 8400.
I had an E6600 @ 3.7ghz with 1.575v. Under watercooling with several other items in the loop, temps were 37'C idle and 59'C under load. These are the temps in Core Temp. Intel TAT reported similar and Asus probe was a few degrees higher as per usual.
NOW installing the E8400 again under water with the E6600 having been in 30 seconds prior, my IDLE temps are HIGHER than the load temps above.... Without even touching the bios leaving all settings at default and the CPU at 3Ghz, it's idling at 44'C and loads in the high 60'C. Reseated, re-applied TIM and still the same. Put E6600 back in and temps again are WAY lower than the 8400. Put 8400 back in, temps sky high again. Insane. At default voltage the E6600 would idle at 24'C and load at around 40'c!!!!!
There IS an issue. No other chip has had this kind of press for high temps. What some of you appear to have forgotten is that the 8400 has only just been released so there are hardly any out in the wild and to have this many reports at this stage is WORRYING.
I have the chip at 4.4Ghz and it's perfectly stable at 1.575v using Orthos for 8 hours. Idles at exactly the same temp as stock.....weird. Loads at 75'C. the E6600 never went above 60'C at this voltage.

Que? The supposed problem isnt high temps, it is temps being read incorrectly. I thought you said you read the whole thread?
And BTW, these beauties are going for $300+ on ebay, and people are buying them. Crazy to think I got mine for $189. The bad news is, that shows Intel that people are willing to pay this much for this chip.

i quit this site since the banned me to teletubies for 2 weeks so this is not me!
first off the cpu works fine - there is nothing in intels product info that says temp sensors are required
second - the stock hsf is totally crap - so warning to anyone toss it, the all aluminum design is to save shipping money and eliinate the costly copper core
finally, you can estimate the cpu temperature form the mobo temp
when first boot you see it says 10 or 15c then both the mobo and cpu heat up to 20c or so. if you know anything about mobo temps you know your off by 10-15c
when you heat the cpu at 100% load you see mobo at 20-25c and cpu at 40c this equals 40-45c mobo and 60c cpu
