Inetl G3258 CPU - overheat - damaged?

[Shaolin_K]

Hi

Earlier today, I built a system with the G3258 chip using the stock Intel cooler.

I kept it all at stock and it booted into windows - so I thought no problem. So I ran the Intel processor diag tool (CPU stress tool) and noticed it had failed, but had stuff to do and forgot about it for a couple of hours. When I came back, I re-ran the test and again it had failed??!!

This was in the afternoon, when the ambient temp of the room was pretty warm! The tool suggested I check the thermal paste - it was at this point that I realised the fan wasn't spinning (I think the plug wasn't plugged in properly)!!

Would I have done any significant damage here? Are there any utilities to check the integrity of CPUs, or do they just work / not work?

Would it have affected its overclocking potential?

Speaking of which, what's the typical overclock for this chip?

Cheers

Extremely unlikely - they are designed to shutdown safely before any damage can occur.. but relying on safety cut-offs is never a great thing!

I'd agree with kalniel, modern chips are built not to kill themselves - I'm not familiar with the stress tool you used, did it give any specifics for the "fail"? I'd imagine if the chip has throttled itself drastically then the utility might suddenly see the chip running at a very low speed and assume something is wrong.

Have you tried running the stress test with the fan connected properly?

I've also never, ever, had a new CPU arrive with a defect or manufacturing issue - not to say that it doesn't happen but I'd be very surprised if the chip was the problem. If the throttling has been ruled out wih adequate cooling, check that your BIOS up to date, RAM all installed correctly, PSU not on its last legs etc.

If a chip is overheating first it will throttle the clock speeds and then it'll shut itself down safely. Only if it overheats really fast will it blow itself up. I would be very surprised if you'd managed to overheat a CPU fast enough to damage it when it's got a heatsink mounted on top of it, whether or not the fan was spinning.

Your post is a bit vague but if the computer was still running when you came back to it a couple of hours later then the CPU definitely didn't overheat.

As for the failure, it's possible that the tool tests whether it can reach it's nominal speed which it may not have been able to with the fan disconnected. Does it not give any details of what the failure was?

Chip will be fine, as others have said, but if you're going to overclock it, put an aftermarket cooler on, the stock intel one will limit any overclock significantly compared to a decent after-market cooler.

To expand on this, Intel's description of the tool is:

... The purpose of the Intel® Processor Diagnostic Tool is to verify the functionality of an Intel® microprocessor. The diagnostic checks for brand identification, verifies the processor operating frequency, tests specific processor features, and performs a stress test on the processor. ...

Hmmm, apparently that's not a valid download for the Atom Z3735 in my tablet. Wonder just how much it stresses the CPU...

If the heatsinks on then it is fine, only a chance in harming it if you forgot to attach the heatsink.

Too much temp, just shorter lifespan.
