CPU overheating problem.

[dredrox]

Hello,

I have problem with AMD Athlon 64 X2 4800+ CPU overheating and i have tried pretty much everything to solve overheating problem.
At night idle temps are like 50-55*c, full load 90-100*c...During day 58-60*c while idle, in load 5 sec to 100*c,
but it does not shutdown at that temperature, it keep going i did load it to 120*c and stop afraid it will die.

CPU fan speed +- 3200rmp, its clean, i did even wash heatsink to ensure there is no dust, replace thermal paste like 10 times with same result.
I have box cooler there is like no chance to not install it properly ^^.
Bios temps are quite same right now 60*c cpu, 40*c system. I have 1 side and 2 back case fans, but temps are same with or without them.
So my question is, since cpu is like 5 years old, i am wondering is there chance that IHS thermal paste is dried up and that leads cpu overheating?

thanks in advance!

If you did the thermal paste 10 times why do you think the paste would be old ? ?
Unless your stating it's all been the same product out of 1 tube...

yea, i did change thermal paste on cpu, but not in, what am asking is, how much dried IHS(Integrated Heat Spreader) thermal paste affect to cpu temperature?

AMD CPUs don't use thermal paste between the die and IHS.
What kind of heatsink is it?  Sounds like it's either not making proper contact or, if it's a heatpipe cooler, that one or more of the heatpipes has a crack in it, which has let the liquid evaporate and therefore the heatpipe has stopped functioning.
The other possibility is a faulty temperature sensor, but it's more likely to be one of the first two.

 this one

how to check is it making proprer contact? It's not moving at all and i did put all amount of thermal paste on cpu, from alot to verry small amount. All same result with temperature.

edit: At first i thought its sensors, heatsink was warm at 90-100*c, so i start playing game and after like 30min pc shutdown...when u touched heatsink after that it was hot, but i could hold it wasnt that hot to burn my fingers like 100*c would do.

OK, not a heatpipe model then so there's no chance of a faulty heatsink, and you said the fan is spinning fine too.

You can check if it's making proper contact in two ways.  Firstly, is the heatsink getting hot, or even warm, or does it stay cold?  Secondly, how did you apply the paste?  If you did it in the way I always do, which is to put a dot around the size of a ball bearing on the CPU, and attach the heatsink, you'll be able to see how it spreads.  It should spread uniformly and cover most of the CPU's surface very thinly and evenly.  If it doesn't, then it's not making proper contact.  This could be due to damage to the heatsink's mounting arms, or damage to the mounting bracket on the motherboard.

heatsink is warm/hot depends how much i load cpu..,but never too hot to burn finger..last time i dont know^^, but i did try that way and there was like 3-4mm empty space around processor. I dont have thermal paste anymore i wasted 2 tubes trying to sove overheating...guess ill just wait september and buy new pc..

Just checking, are you overcloking this cpu?

[dredrox]

nope, never did.

[Yasjalnadie]

Also try other temp monitoring software just to make sure its correct.

[dredrox]

I did try Speccy, Core Temp, speed fan, aida64, everything is quite same +- 3/4*c

but it does not shutdown at that temperature, it keep going i did load it to 120*c and stop afraid it will die.

Did you try updating the BIOS if a newer version is available?

[dredrox]

nope, dont see how that would help ^^, anyway i just ordered Cooler Master Hyper TX3 EVO (they don't have 212 evo) if that doesnt help, ill just melt it with jet lighter and cry for new pc at parents.
