Processors

I've had a Ryzen 5 5500 for a few months now, and I've noted that I probably got a bad bin on it.

When I got it, I was using a Deepcool Gammaxx 400 V2 as my CPU cooler with the Maxtor CTG9 thermal paste, and under stock conditions it reached 90C on stress tests and 85C on games.

I tried switching pastes to a worse one I had, but no luck. So I switched my CPU cooler to a Deepcool AG 400 Plus. I firstly used it with the stock deepcool paste that came with it, and I had a very little reduction. From 90C in stock, to about 82C. I tried switching pastes again, and nothing changed.

There was one time I've had to deal with some stuff and I also fused the Gammaxx 400 V2 heatsink with the AG 400 Plus fans, and it would reach about 80C, and that was using the worst paste I have here, since I had no other, but I thought it wouldn't make difference because of my previous tests.

So after a while I came back to the AG 400 Plus, but with the worse thermal paste as well. It was still reaching 82-83c in stock, enabling Curve Optimizer per core at -25 helped it, making it maintain a stable 75C when stress testing.. but, overtime, that 75C turned into 80C once again.

I've also used 2 different boards on several occasions, these being the MSI A320M-A Pro and the MSI B450M PRO-VDH MAX

I've also used 2 different cases, and no results.

My conclusion is that I've probably got a bad bin, but maybe someone out there knows something.

To add - recently I tried overclocking it just to see how much it would heat up, I went from 4.2GHz to 4.45GHz at 1.375v, any lower than that it would BSOD. It reached a 105W power draw, and the temps were about 87-88C. Though, I believe this is on my side because it was fixed voltage.

Overheating is once again one, if not the most debated topic. You need to be wary of several factors, everything counts!

Room temperature, what case and size, fan type and positioning, cooler and as you mentioned, thermal paste among others.

Example, a glass front is not great for airflow and mini ITX is challenging to make it cool.

About the bad bin, normally bad silicon require more voltage to operate, noticeable on overclocks not getting stable enough at a given vCore voltage. So if you achieved -24, thats not bad.

Another thing, are those average or max temperatures? Peaking at 80 is super OK, even at 90C but if its staying at 90ish all the time you could, maybe, eventually enter throttling temps.

I find the cooler a bit "skinny" but it should be able to deal with your CPU, try getting a nice thermal paste like Artic or Noctua, they are not that expensive. You could try putting 2 fans on the cooler if possible for that push-pull and maybe a couple of C lower.

Then instead of fixed voltages or curve optimizer, try negative offset undervolting. Something like -0.1v or 0.05v if it crashes during stress test.

But don't worry too much yet and share more details about the rig.

Good luck

The AG400 Plus I have already has 2 fans. This is my rig.

widedisplay, 5500 maximum temperature is specified at 90C, so why do you think it is overheating? What are you measuring temperatures with? If not Ryzen Master (RM) then it is probably wrong. Please post a screenshot of RM running Cinebench R24 Multi core. Thanks and enjoy, John.
