Temperature difference between Cores on CPU.

[AshleyKitty123]

Hello everyone! I was doing some stress testing on my pc and i was noticing some very strange temperatures. At idle, the temps were ok at around 46 C° on both cores, but when i start a stress test, 1 core stays at a normal temp of around 70 C° , but the second core goes as high as 94 C°!!!. I re-applied thermal paste multiple times, tighten the heatsink mounting clips to no success.How can i fix this? 

 

CPU: Athlon 64 X2 4400+ Dual Core 65nm Brishbane. 

Heatsink: Stock AMD Heatsink 

Thermal Paste : Thermal Grizzly Kryonaut.

What test are you running? Are both cores being stressed during the stress test or just one core? What temp monitoring software are you using?

 

What are you hoping to use the machine for? The Athlon X2 4400 is over 13 years old and it is going to struggle a lot in general daily tasks. You may want to consider replacing the system. The CPU is worth less than the thermal paste you're using on it.

I wouldn't worry too much about how it performs and temperatures under synthetic loads in stress tests, and instead just try to use it for light tasks until you are able to replace it.

chances are that the thermal solution underneath the lid has deteriorated more on one side, than it did on the other.

 

after 13 years you should be happy it's not vominting up capacitor juices all over your desk tho, be happy its as stable as it is.

1:Im using Aida 64 for the stress test and temp monitoring (The temperatures are exactly the same with prime95). 

2:Both cores are being stressed. 

3: It's our main Home computer, we use it for storing our photos, surfing the internet from time to time and some light gaming.

Is there any reason why you've decided to perform stress tests on the machine now after 10+ years? Are there any underlying issues with the machine that you are trying to diagnose and solve by running the stress tests?

 

It's a very old CPU with a very old AMD stock heatsink. Termperatures aren't going to be great. Check that the fan on the heatsink is functioning correctly and also check the BIOS for the fan profile and make sure the fan is increasing the fans RPM as the CPU temp increases.

 

Probably time to start to budget and plan for replacing the computer if that is at all possible.

No. There are no problems that i can think of with this computer other than a few loud fans (that im gonna replace shortly) and these weird temps. 

 

I do known its a very old CPU and a very old heatsink. For the heatsink part, i  placed an order for a new cooler, that should solve the average high temps and lack of airflow on the motherboard's VRM.

 

I already intend to build a new desktop to replace my "Gaming" notebook that i use. The reason why is still focus some of my attention on this pc is because it is the first ever computer that my family owned and it holds a special place in my heart. It would really be sad to see it go.(it sounds kinda weird but I secretly made a promise that ill never throw it out ?  ).

I decided to delid it, and found out that @manikyath was right. The TIM between the IHS and the die has worn out more around the center of the die, and that paste was basicaly rock solid. Fingers crossed that it still works when i put it back together! ??

After deliding, reapplying the paste and re-liding, It works, and the temperatures improved 10 flold. Now the temp difference between Cores is around 6-8 °C (witch, from what i've read is normal) instead of the 20 °C before. Special thanks to both of you for helping me!
