CPU overheating after change. why?

I've been using amd athlon 64 3500+ 2,2 Ghz and decided to change it for amd athlon 64 x2 5000+ 2,6 Ghz for a little bit better performance (that's just all I need, I don't want to spend money on anything better).
I am using standard cooling for 3500+. I thought that there would be no problem with this, because power consumption is almost the same (62W for 3500+ and 65W for 5000+). I even thought that serial cooling is the same for all 64s. But after replacing CPU, during intense use temperature just raises and never stops raising.
Any ideas? Or am I completely wrong and simply need new cooler?

how hot is it getting and sounds like you didn't use thermal paste which is what transfers the heat from the cpu to the cooler and its fins so that it can disipate.
 
As Jonny said, did you clean off the old thermal paste and apply fresh paste?
 
I have no idea how high it would go, I stopped stress testing at ~90.
Paste isn't solution, I tried it with and without, it's sure working better with paste, but in the end it's still overheating. People say thermal paste can give you ~10 degrees.
 
You do need the paste, and like everyone said. Did you clean the paste off the cpu and cooler and re-apply it on chip only, paper thin amount. Otherwise get a after market cooler.
 
Wattage or not, a dual core Athlon X2 5000 will put out more heat then a single core Athlon 3500. Like said above you need to clean off the old paste and just put about the amount of a grain of rice. Either let the heatsink spread it or spread it out as even as you can then apply the heatsink.
 
I owned that very cpu...as said, you need to clean the paste off, apply a little dab in the center and replace the heatsink...make sure your C&Q is enabled and you should be good to go.
 
I've used paste and changed cooling for

Still exactly the same problem.
Can something be wrong with this CPU? Or maybe is there something wrong you can do with instalation that causes temparatures to rise enormously?
Note that silimar processor is running well with exactly the same settings and even without thermal paste.

This is how it looks, 100 degrees in 5 minutes.

...i dont know where your getting the idea you dont need thermal paste. by the looks of things your applying too little or too much, you just need a rice grain sized drop in the center of the amd heatsink. make sure you cleaned off your old thermal compound before with 90 percent rubbing alcohol and you should be fine. there is no reason this 65w chip should hit even 80. mine would sit at mid twenties and hit mid fourties on the stock cooler. also that retention clip on that cooler doesnt look very good to me, id stick with the stock amd cooler.

This cooler gives better results than stock cooler. It was almost made specifically for 5000+ (they did some tests on it, and say that load temperature should be ~50).
Trust me, I know how to use thermal paste and I know the exact temperature difference it has to offer and it's not 60 degrees.


Anyway thanks for all the answers.
I kinda solved this problem by myself. For anyone interested: it seems that my CPU/motherboard/power suply has some problems with my CPU running at full speed, but after downclocking it a bit (2600Mhz->2400Mhz) and lowering voltage slightly (14V->12V) it's working well, not going over 60C on stress tests.
Still have no idea why it's acting like an oven on regular frequency.
 
What kind of case cooling you got. Its suppost to run at 2.6ghz. You got Cool & Quiet enabled in the bios, it should throttle it down when not under load. But you will have the same problem with heat when its under load.
