So I have stock cooler on my AMD athlon x4 760k 100w CPU reaching 90degrees under stress test playing games like arma 3 tit hits 70-75 is it just that the stock cooler is crap and I need a new one or is my CPU busted ? I'm going to under clock for now

Did you try a finger test? I'm not using the stock cooler on my Athlon X4 750K -it's an old copper heatpipe cooler from an original Phenom- and I'm flying with a reported thermal margin of 20C at 1.45v. Use OverDrive for your temp readings.

I've seen bigger chipset heatsinks than the stock cooler :)

Over drive I'll check it out I've been using stock hsf currently I use speccy and HW monitor they read the exact same so I don't know the 750k is a nice CPU but for a 5er you shoulda got the 760k

what temp are you getting in BIOS?

No difference between the Trinity/Richland CPU cores -- the 750K goes on the E-Blast for $70 every month or so. And, if you are not running 4.5GHz+ without throttling, **You Are Doing It Wrong** :lol: 

HWMonitor and other utilities do not give accurate readings -- by using AOD it will report your 'Thermal Margin' under the CPU Status tab.

in bios about 36-40c

Well your socket temps seem fine. I don't think you should be worried, speccy does the same thing to me under load (A10-6800k reports 85°) but my socket temps don't go above 54° and amd overdrive margin never drops below 30 so it can't be right.

That's great.

I'm running 4.6GHz at 1.45v +/- with a thermal margin of 20C, UNB at 2500MHz-1.25v, with some GSkill 2400MHz Cas10. Occasionally, the margin will drop to 18-19C.

Trinity/Richland chips are "volt-leaky" and love the juice. Even more so with the CUs disabled. If you think you have a temp issue, simply place your finger on the sink. If you pull back a smoking nub, you might have a problem :D  I'll bet you don't, especially if you are running stock.

The "volts & heat" from the chips come from the on-board graphics engine. The CPU cores only take up 130mm2 or so on a 256mm2 chip and are quite efficient. If the graphics engine on the die is not under load they become even more so.

If LTF is using a discreet card, that's why his thermal margin never drops below 30C because the CUs never max their volt load.

You guessed correctly, I am indeed using a discrete card instead of the igp :)

You should be able to get a nice overclock with the 212 evo. 4.5ghz is pretty common
