Ryzen 5 2600 High Temps

[Exogenesis]

Hello

I purchased this prebuilt system from Overclockers about 6 months ago: https://www.overclockers.co.uk/ocuk...zen-5-2600-rx-590-8gb-graphics-fs-1aq-og.html

It has a Ryzen 2600 with stock stealth cooler. The cooler that shipped with the PC had a fault (vibrations at high fan speeds), so I had a replacement stock cooler sent out (the same AMD stealth cooler).

The vibrations have gone and all seemed fine, but curiosity got the best of me and I wanted to see what sort of temps I was getting.

At idle I'm getting 40-45, but in games like PUBG it goes as high as 87.

I've looked around online and seem to get mixed answers in terms of what's dangerous and what isn't with the Ryzen temps, so I wondered if anyone could help me out?

I just want to enjoy my PC but I'm worried about the temps.

Stock Stealth is pretty rubbish but it's what AMD supply.

What is the airflow like in the case itself?

The system came with 1 front fan and 1 at the back.
There's also a Vega 56 below the CPU (facing down), and I've read that they blow out at lot of hot air.

I wish I'd checked my temps with the previous cooler to see if anything has changed, but I'm pretty certain I have fit the new cooler correctly.

I see different opinions on the net, some saying it's fine as it's not reaching the CPUs max temp, others say differently.
