[SOLVED] Keep replacing thermal paste, but not working

[dbqkd]

Hello guys,

I’m using TS140 as NAS server with Intel Xeon E3-1225 v3 3.2GHz, running 24/7 almost 5 years. It keeps shutting down recently. I have replaced power supply and applied new thermal paste:

• First thermal paste applied lasts for few months
• Second thermal paste applied lasts for few weeks
• Third thermal paste applied lasts for few days

Is it the thermal paste issue? Or something else?
Any idea how to fix it?

Thanks

Is something vibrating causing the thermal paste to break. Maybe use better thermal paste everyone is a critic with thermal paste i use Artic Silver 5

I’m using Arctic MX-4 thermal compound. Should I change to Artic Silver 5? Or is the CPU itself having issue?

Thermal paste is basically just the same so this sounds like a CPU issue

Does it worth to replace the CPU? Or just buy a new NAS system?

Sounds like a cpu/motherboard issue, and my guess is motherboard vs cpu if the cpu has been on stock speeds.

Could also just be the power supply. I would actually try that first if you've got a spare to test with.

Tried a new power supply, but having thesame issue. How do I know if it is cpu or mainboard? Anyway to test it?

Thanks

Gotcha. Unfortunately, you would need to swap the motherboard or cpu for a 'known working' part. I would take the cpu and put it in another system and test it there. If it works 100%, which I suspect it would, then motherboard is the culprit.

Thanks SamirD,

I have bought a new system for now.
I will try it out to find out defective part.
