I actually had a faulty Ryzen 1700x I think? 50 to 60c idle temp.

Hi,

Setup is MSI B350 Tomahawk and Corsair H110i.

Upon first boot it was sat at 55c in the bios, I thought it may be a buggy BIOS. But I booted into Windows (on my old install) and saw it was now at 60c in the AMD Ryzen utlity.

Remounted the H110i twice with new paste, no luck, identical temps. Putting it under load was impossible as it hit 70c+ pretty much instantly. It was also very loud.

At this point I really am scratching my head wondering how the H110i could be faulty, wondered if the pump wasn't working etc. I was thinking maybe I could have mounted it wrong, but it really is very very simple to install on the AM4 socket. I saw other people with the B350 Tomahawk reporting normal temps, so I ruled that out.

So I picked up a Ryzen 1700 with the stock cooler.

Firstly I fitted the stock cooler with the 1700x... 62c to 69c at idle! at this point I knew it had to be the CPU.

Fitted the 1700 with the H110i, 31c idle...

So yeah I am RMA'ing the CPU. I have built 100's if not 1000's of PC's and I've never had a faulty CPU. Has anyone else had a faulty Ryzen CPU?

Hope this helps if anyone else has the same issue with stupidly high temps!

I know this might not be the case but have you checked

Yep... 100% not a heatsink problem, it was very tight to the CPU with both the H110i and the stock cooler. Also the problem disappeared when swapping from the 1700x to the 1700 but with the same cooler.

Might be the motherboard overvolting the CPU??

CPU-z reported normal voltage. I have tried up to 1.45v on the 1700 and I am still nowhere near the temps the 1700x was reporting.

Surely not to the tune of 60 degrees at idle though?

OP does sound like he's got a weird one. I guess it's possible to get a badly made unit without enough/any solder twixt the chip and heatspreader or something... sooner or later, someone's gonna get the duffer.

Sorry yeah I should have added that when I ran the built in CPU-Z benchmark it was hitting over 70c pretty much instantly on the single thread test, I stopped it immediately. That was with the H110i too.

Very odd.
What does everyone else's BIOS have for the temp? Mine says 38c (1800X).

But with a 1700x...

Was the notched side on the cooler bracket correct?

Yes everything regarding cooler installation was correct, the problem follows the CPU, it doesn't matter which cooler I use.

I can put the 1700x back in and run the CPU-Z bench if required

Update, the retailer confirmed that the CPU was faulty and have refunded me.

Just to add to this thread MSI B350 Tomahawk massively exaggerates idle temperature in the BIOS for me.

I haven't been able to figure out why. I'm guessing the motherboard sensor is poorpy calibrated.

Temps are a lot cooler in Windows and only reach BIOS reported temps of 60C under heavy load, 70C when overclocked.

My temps were the same in the bios and in Windows. Both stupidly high at stock speeds with voltage set to Auto.

Good to hear that you got your refund, you might have read it elsewhere but 1700X and 1800X temp reporting will be 20C higher than 1700 as said by AMD. For this reason you need to -20c from the reported temp until software can be updated to reflect this change.

Yep I did read that! It would have been useful if they told everyone this before. It was also their own app I was running, you'd think that would know!

It also fooled the retailer evidently as they said it was faulty too. Maybe it was. Guess we'll never know.
