It's pretty straight forward, you will either use direct die cooling with custom parts from der8auer and enjoy lower temps or you will run stock. And with how Amazon returns work it's never been easier to get into de-lidding and direct die cooling. I have personally destroyed and broken 3-5 processors so far. All of which I just put the IHS back onto and shipped back to Amazon and got a full return on my credit card. I then repeated until I figured it out and did it properly and it worked. If you want your AMD Ryzen 7000 series CPU to be 75-80c under load you will have to use the aforementioned methods. Otherwise just accept 95c is the stock accepted temperature and there is nothing you can do about it without de-lidding and direct die cooling.

[@Neomeniaaa]

In a way it makes a lot of sense that it does boost till 95 degrees celsius. It's kinda doing the same that laptop parts have done for god knows how long. Pretty sure linus once said as well that it was because an engineer said that "if its not hitting the thermal limit that means there is performance left on the table". Feel like that is exactly what is going on here. Edit: so I actually saw some people use the eco mode for the 7000 series chips (eco mode locks it to 105 watts) and the performance was almost the same. They didnt test extensively and I'd love to see more testing but from the looks of it the high power draw is mostly a dick measuring contest while if you reduce the power draw using that eco mode the performance is still almost the same with normal heat out as well.

[@halbouma6720]

Exactly, we're seeing competition at work here. Back in the day you'd have to buy a special more expensive version of the chip for either HE (low power), or extreme. Now you get all rolled into one. Its going to give you 95% of your top performance auto-tuned for you based on whatever your silicon lottery / setup is. Or if you clamp the power to 65W-88W you get the efficiency model. I prefer this because like Linus said, it always sucks if you later find out you could have spent a couple days overclocking your CPU to get another 30% performance (at higher power draw of course and then wonder if you're hurting the chip lol).

I had to get used to that increase in safe temps when I went from 3900x to 5950x. Despite having a custom loop with dual 360 rads the 5950x just races up towards high 80's but it's happy with it. Just like in your test, the water temps aren't saturated, and as soon as the test finishes the CPU temp plummets back down to mid 30's. I even repasted the heatsink as I was worried the block wasn't drawing the heat off the IHS. It's just down to physics, if you cream that many cores working that fast in such a small space there is a limit to the thermal transfer from die to IHS to heatsink. The 5950x was at the limit, the 7950x seems to redefined the limit.

If I could keep it just under 90 degrees it boosted really well but if I left pbo at what the motherboard gave it, it just threw voltage at it and it performed worse.

If you have that cranked to the max and measure in front of the heater it'll be a high temperature compared to the room. Edit: in short, the processor core is getting really hot really quick but since it hasn't equalized with the cooling capacity of the heatsink (the metal in an air cooler or the liquid in a water cooler), it can drop really quickly as shown in the video.

@@Mike__B Doesnt the liquid move the heat faster to the ambient air than heatpipes in an air cooler?

[@Mike__B]

@@L1ft0ff I'm not sure how fast heat pipes move their liquid/vapor around, but in a water cooler you tend to have a LOT more fluid than in heat pipes and that means a much greater heat capacity so you can pull lots of energy to the radiator where it can then transfer that heat to the radiator which then gets blown out of the case via fans. It's a little more complicated than saying one technology is better than the other, but water cooling definitely has the potential to be better at cooling than "air coolers" (with heat pipes), I believe the big limitation with heat pipes is they can't be terribly long because the vapor in them condenses quickly as it gets away from the heat source.

What I'd like to see is a plot of efficiency (compute performace / W) vs the different eco modes and unconstrained (non-eco mode).

[@mdswish]

Another thing to consider is the heat spreader on Zen 4 is quite thick. It stands to reason that it takes a while to conduct all the heat from the CCDs to the cold plate of whatever cooler you're using. Longer than it would have on Zen 3. This is a side effect of AMD's decision to allow backwards compatibility with AM4 coolers and mounting brackets. For every design decision like that, it causes a trade-off of some sort, and in this case it's less efficient heat transfer from the CCDs to the heat spreader to the cooler.

[@sysbofh]

I wonder, since the heat exchange is from above, if they couldn't just make the base ticker. It would transfer less heat to the board, but the heat spreader would be more efficient.

[@mdswish]

@@sysbofh The reason the base is thinner this generation is because they moved the SMDs from the bottom side of the CPU to the top. That's why the heat spreader has all those cutouts in it and just little legs gluing it to the CPU substrate. That is another design choice they made in order to allow for more data pins in the socket while still having the same general dimensions as socket AM4. Had they left the SMDs on the bottom and stuck with a thinner heat spreader it would have made the CPU socket noticeably larger and forced everyone with an AM4 cooler to at least buy a AM4 > AM5 conversion kit or an entirely new CPU cooler to ensure proper cooler contact. This on a new platform where the adoption cost is already high due to requiring DDR5 and a new motherboard in addition to the CPU itself. So all in all, there is a perfectly rational logic to it. And realistically, while the CPUs do run hot, they are stable at those speeds and at those temps. So as long as you can live with those temps helping to heat your computer room all year round, it's really not that big of a deal.

If you cool the crap out of it, it will boost higher but still try to hit 95C. You have an LN2 pot, it should boost to 5400 on all cores with stock BIOS settings.

I think what a lot of people don't really understand is if a device is generating 250 watts of heat it doesn't really matter if the hotspot temperature is 95 or 80 it's still the same amount of heat being generated and your room won't warm up any faster because 250 watts of heat = 250 watts of heat. Temperature is like voltage, if I have 120 volts at 1 amp it generates 120W and if I have 12v at 10 amps I still have 120 watts. What is missing in the equation is the actual density of the heat because all they are measuring is a tiny spot on the die. That's like lighting a candle in a room, while the temperature is higher right next to the candle the overall room temperature doesn't really change because the density of the heat is so small What really needs to be done is monitor the water temperature on a new 7950 drawing 220 watts and a 5950 also drawing 220 watts. The fact that it cools down so fast tells me that actual density of the heat isn't any more than a normal 80C system drawing 220 watts. What I suspect will happen in this experiment is the water temperature on both system will be roughly the same even though there is a fairly large difference between the hotspot temperatures after all 220 watts is 220 watts To cool this CPU properly is really no different than any other CPU, concentrate less on temperature and instead how many watts of heat your cooling system is capable of dissipating.

Hey Jay, I believe it's because under full load, the auto overclocking will just keep rising until it hits that 95 degree safe limit. It only stops increasing its speed once it hits 95 degrees. It's how AMD decided to control it on purpose. It makes it easier for the user, and also safer, as some people bring their systems to the very edge, and run it like that all the time, and with it shorten the life of their processor, often significantly.

I doubt the temps can transfer well enough through the the chip pcb itself to affect the motherboard. Older ryzen pins would be falling off left and right if that were a thing. Especially since the heat is instantly passed through the ihs. Things generally try to take the path of least resistance. You're not gonna see lightning try to bore a hole through a wall to get to you, it will jump to whatever metallic thing is nearby.

@@Wheres_my_Dragonator I get that, but if you've ever stuck your finger on the back of the PCB of your GPU, you know that gets pretty toasty, even under moderate loads.

@@Wheres_my_Dragonator It doesn't have to transfer from the CPU to the mobo, the mobo itself will heat up (unless it is a very expensive one with overboard VRMs) from the 100W+ loads all the time. The VRM will have to handle the increased loads and the CPU socket will have to sink the heat from the CPU and all the amps rushing through it. In 8core + territory we are talking 200W+ now, this is bonkers..... b350 had 1 or 2 boards that could handle 100W, b450 had a few more and b550 can generally run it just fine, but b550 was more expensive, because of that. The next b650 will have to be even more expesive or caps will start blowing up. And probably forget about cheap electrolitic caps, they'll have to use the more expensive solid ones. There is a reason 65W CPUs were/are the norm, with 90-100W ones being for "enthusiasts", more than that is FX9590 territory and where Threadrippers used to be. When does this end ? Next gen 300W ?

[@TrowGundam]

With Ryzen 5000, Curve Optimizer was the way to go. Don't trust Ryzen Master's auto tuning it does. It'll zero in on offsets that are way too high. They'll be stable in the short term, sure, but they will cause crashes over time. Although the values it finds could be used as a good starting point for manual tuning. But the curve optimizer lets you undervolt (or overvolt, but that's not what most of the community used it for) each individual core separately. Doing this can really help control the power consumption and heat generated by the CPU. Then after that you can mess with the PBO settings (PPT, EDC and TDC) to use the extra thermal and power headroom you got from the Curve Optimizer to bring up the overall performance. It's definitely a very different style of tuning than just telling it to run higher clocks and increasing the voltage as necessary. I feel it is better for an every day use system though. It just takes a really long time to dial in the values. It took me like 3+ weeks of running stress tests to find the rock solid stable offsets for all my cores, but it was worth it.

For any cooling method, the temperature gradient across the coolest part of the cooler and the middle of the chip thickness are what determines overall cooling capacity. Any extra material, distance, whatever increases the physical width of that distance.

[@tweakmixbuilds]

5:18 I think you can call it as generated heat - as equivalent of the work that the cpu was actually doing by the time that the system reports its temperature reading. And what the AIO is actually cooling is the residual heat that was dissipated from the IHS to the cold plate of the AIO. And that the AIO's job is to continue keeping its cold plate cool so that heat dissipation process keeps on going, keeping the cpu as cool as possible. If cpu's IHS and AIO's or any other cooler's cold plate becomes equal in temperature, heat dissipation stops. And cpu cooling stops as well.

Do you think now with the way this cpu temp is set up, it will effect the temp on the gpu in a single custom loop? Thanks for the video

Unlikely, it isn't running at 95C because it can't get rid of heat fast enough. More that it doesn't care about the temp. So the waste heat wattage going into the loop won't be much different than any other equivalent TDP drawing cpu.

A good analogy about this temperature behavior would be the cooling system of a car engine. It's designed to keep the coolant in the 80-95°C and oil at 90-120°C no matter the load.

I think we just have to get used to the 95°C as a "norm". It makes a lot of sense, when you think about it.

If it's gonna self-overclock until it reaches a target temp, there needs to be a bios setting to adjust that target temp. 95C is just ridiculous.
