Ryzen 9 3900X: Wraith Prism RGB Stock Cooler vs. 360mm AIO Liquid Cooler

Yeah, I’d definitely buy a better cooler for a 3900X, a $500 CPU. Call me vain but I don’t like the look or the noise of the wraith cooler. And besides, there’s something awesome about buying a better cooler. I actually use a Noctua NH-D15 with custom industrial grade Noctua fans. It’s a lot quieter than my previous H110i as I can have the top of my case covered and there’s no pump noise. The performance is more than good enough. I also think it looks better, especially with those mod tops on it. Not good value at all though once you add the custom parts.

I actually think it’s a bit of a shame that the excellent R5 3600 only comes with the wraith stealth. The wraith stealth is quite poor imo and Steve’s review stated the chip was hitting a thermal limit with it.

Would be stupid from AMDs part to give you a cooler that will not let the CPU stretch its legs and give you the maximum performance.

How exactly does AutoOC for PBO work? What does it change compared to PBO alone? What can we set using this function? Increase clock target? Increase power budget? I can't find any good explanation for this function.
How does it differ from ZEN+ implementation.

here you go :

2. Gamers Nexus: “Precision Boost” is not an abbreviation for “Precision Boost Overdrive,” it’s actually a different thing: Precision Boost is like XFR, AMD’s Extended Frequency Range boosting table for boosting a limited number of cores when possible. XFR was introduced with the first Ryzen series CPUs. Precision Boost takes into account three numbers in deciding how many cores can boost and when, and those numbers are PPT, TDC, and EDC, as well as temperature and the chip’s max boost clock. Precision Boost is enabled on a stock CPU, Precision Boost Overdrive is not. What PBO does not ever do is boost the frequency beyond the advertised CPU clocks, which is a major point that people have confused.

If there were legs to stretch...
"There is no manual OC headroom with Ryzen 3000." -Hallock (AMD)
"He couldn't reach max boost with $500 custom water cooling." -De8auer talking about a friend
"I don't recommend using the box cooler even if you run the chip at stock." -Gamers Nexus

When a $255 6T i5 is as fast as the competitors' $500 24T "flagship."
WTF are you even talking about? The $500 3900X is on average about 30% faster than the $485 9900K and within 5% in gaming. If you literally only game tho, you shouldn't bother with either. You should get the $200 3600, which outperforms your precious $255 i5 chip in gaming and for less money.

Given that my 1600 came with, spire is it?, I can imagine a number of users just switching their 1600's out for a 3600 and using the 1600 cooler instead.
Its what I plan to do, I wonder if it will actually make any difference, the 1600 is a 95w chip and the 3600 is 65w.

I'm sorry but this test is completely pointless if you do not show temperatures. or talk about the noise difference between the two coolers.
Unless you have been living under a rock you should already know that ryzen 3 doesn't overclock well so any highend cooler is a complete waste.

You guys keep saying you're going to show off temps (some of your graphs are even labeled as "temperature") but I just see Fan RPMs.... This is a pretty disappointing test, it doesn't show any good empirical data. RPMs can be high with temperatures low for a multitude of reasons.

Please show the real data.

So only reason is if you need a dead silent pc. stock cooler upgrade isnt worth upgrading.
amazing.
I'd like to say you're right... but they didn't even show the actual temperatures. Just Fan RPMs and clock speeds which doesn't really tell me much in cooler performance. They don't even have the right data points for their graph labels. But it has already been proven that AIO/Liquid Cooling has marginal cooling efficiency improvements over air cooling.

When you test a 360 CLC on a consumer chip that has zero OC'ing headroom, and then turn around and say the enthusiast class 9900K is hot.....

What I'd like to see in these cooler tests is how an one type of cooler affects the other components nearby (VRM, etc) compared to the other.

If I reduce the maximum temperature from almost 90 degress down to just over 70 degrees, will the CPU last longer? That, even more than quieter operation, is what would tempt me into getting a fancier cooler: now that the 3950X is announced, and a fancy cooler is recommended for it, I was wondering if the stock cooler was barely adequate for the 3900X as well, but apparently not.
