Is my cpu malfunctioning or did I seat it wrong?

Try reseating your heatsink.

Slightly off topic, has someone invented a much easier way to "unstuck" sensors lately that the rest of us don't know about?

I reseated the heatsink and even took out the mobo and checked the pins (Im very bored right now lol)

im using a Xigamatex HDT-S1283 btw

oh and to sirrell as tempting as that may seem im going to have to go with a no on tht one... plus the guy didnt have any load on the cpu when he did it and if he did it would melt the tape (jk lol)

Please ppl. There is nothing wrong with your cpu. CPU's is made in a VERY advanced process in cleanrooms and tested bla bla.
CPU's dont fail unless you can smell the burnt silicon!
You cant trust a program like speedfan that much, even thou its good app.
Still I would look at that cooler, is it mouted ok.

so perzy, in your eyes, all silicon chips that come off the production line are absolutely identical, and perform the exact same? not even a molecule different? Its perfectly possible that there is some manufacturing defect.... although the heat sink is still the much more likely answer...

Could it be possible that intel accidentally put in the wrong measurement system into the chips for measuring on Core 0 because even if the heastink wasnt seated right it shouldnt give a 20C diff

It's just a stuck sensor. I wouldn't worry too much.

Dude, your temp sensors are working well according to the real temp fluctuation test. The cores are mounted side by side under that plate and one is alot hotter than the other, I suspect one of your hsf pins isn't fastened into the mobo properly, why dont you simply get a crossbow bracket for the xiggy and that way you can be sure there's enough pressure on the cpu for good conduction and if that doesn't work return your cpu, because that temp difference is massive. Also check you cpu for flatness and reapply some arctic silver after cleaning the cpu properly.
