I was expecting it to be competitive like reniors

For this temperature for you it is ok?

Upgraded my CPU cooler to Corsair iCUE H150i Elite Capellix..

Temp about to settle down at 70'c under Prime95 stress test. However, the clocks speed for the 3700X only at 37xx mhz when im doing stress test. Is this consider normal? 

just choose any thermal paste that you mentioned.

as long the cpu cooler is rated for your cpu max boosted tdp, 3 degree plus minus doesn't affect much la…

I have both, have used both.

NTH2 is better because it doesn't degrade as quickly as Kryonaut, also won't suffer from pump out issue (this is an issue for Zen CPUs because the IHS is convex). I have used Kryonaut since 2014 and my experience is that you need to change them out in about ~1 year or so. NTH2 has been more than 1 year in my 3900x system, still hasn't suffered any degradation. On my 5900x system, I'm still using the Kryonaut on it but these few weeks I have noticed higher peak temps. No, it's not because of weather affecting ambient temp either because my room temp is always controlled at 22c whenever PC is turned on.

That said, they both perform exactly the same temps wise when both are freshly applied. 0.5c difference is NOT a difference ya. 

Anyone with Ryzen 3000 series suffers from whea error code 18, black screen bsod reboot?

Actually don't have high hopes for their 3D v-cache either. Zen 3 is complicated enough as is, just tacking on massive amounts of L3 isn't going to alleviate the problems it already has. This is just a stop gap for AMD so they can have something to compete with ADL (eventhough it's a futile attempt) so that they have a buffer before launching Zen 4.

It's made for people who are on Zen 2 who has a good X570 board, good b-die DDR4s and not wanting to wait until Zen 4 releases in Q4 2022 because FOMO.

Honestly, it's a pointless release just like Coffee Lake Refresh was.

Or rocketlake

Yeap if they did that then we would have raptorlake today and alderlake last year lol.. but owell, when you have a bad ceo, no matter how good your engineers are, it wont be fruitful.

I guess AMD doesn't want people to buy their CPU.

Core i7-12700K price level.

Obviously 5800x is the better choice since it's only RM300 extra.

But the issue with the single chiplet Zen 3s is that it gets stupidly hot. Your wraith prism will not be enough to handle it without running at constant 100% fanspeed and with PBO disabled, which kinda defeats the purpose of the 5800x gaming prowess to begin with.

So if you're going for the 5800x, do pick up a better cooler to go with it.

OTOH the 5700x just launched for RM1.3k, maybe you can get that for a 1:1 exchange? Would be a better choice than the 5800x IMO.
