The effort put in this video for this specific situation is amazing thanks.

[@wiktec]

I would definitely lock this cpu at 125W as the performance loss is too small to justify using it in unlimited mode.

[@jessielees]

whats it clocking at 125W?

[@wiktec]

@@jessielees I'm not remember the clocks, but the drop in frequency is less than 200mhz.

[@AnatoleBranch]

@@wiktec I think its around 5100Mhz all cores, it performs very well with some undervolting and watt reduction. With the N15 I'm getting 81 degree's and CBR23 score of 29,700, With a 160 TDP, still close to 5300 all cores.

[@checkmeowt2938]

hey i didn't see the 420 listed in your chart.. Just curious - Did you see any improvements with the big 420 rad? Also if i'm reading this right, you saw better temps on the 280 vs the 360 ? (arctic liquid freeze II). currently upgrading me 7700k to either: 12900k, 13700k, or 7900x. currently running a 280 rad, but can fit a 420 if there are some actual improvements, not just 1-2c.

[@BillNyeTheRussianGuy]

Thanks for this video! Microcenter had a 7900x bundle I couldn't refuse but I was coming from a 6700k so I had no clue what thermal headroom i needed for the upgrade.

[@STSYT]

Sure! Glad you enjoyed it!

[@rejectmodernity99]

Hey man! I wanted to just ask because i am going with the 7900x and im getting the arctic liquid freezer II 360mm for about 50 euros because my freind is selling it for me and it hasnt been used at all and i will pair it with the 7900x so is that good?

[@krusteh]

Hey, thanks for the video, it's exactly what I was looking for in making a decision for my 7900x. One question thought, why is there a difference between the top 2 coolers? Aren't they the same model + extra RGB lights on one of them? I'm looking to buy one of them, but the RGB part is throwing me off haha. I'm not really interested in the lights, but if it runs cooler, why not. :)

[@Frejjan]

Great video

[@XeninWorx]

Did you try using the Noctua offset bracket?

[@joshplays7491]

will my chip be ok if i only game on it with a lower end cooler master, not looking for it to be mega cool just below 90

[@yingbxua6240]

I wish you could also test id-cooling. Xilence sorta reminds me of them.... Also fairly cheap, but decent in some variants. Now what I read from this video - I can undervolt 7900x and use 32eur cooler with this in my mITX case - fingers crossed ⚔️ ))

If you have an Asus mainboard make test with the last 0705 Bios. Now the cpu's are cooler than before. My 7700X is 10 degrees cooler now.

[@liboud22]

Currently running my 7900x @ 170W, 5.7Ghz Max. Cooling it with SilverStone AK620, Never goes above 95 degrees C. hits 1400+ pts in Cinebench 2024 and 26000+ Cinebench R23.

[@soltysss]

well for me second fan for nh-d15 didn't fit, so yeah, not great. At the beginning I had water cooler but it didn't cool that beast, that when I decided to buy best air cooler) correction: added case fans to optimize case airflow - now NH-D15 tamed that CPU)

[@ethanlimberger3886]

Hey man not sure if this is because later updates but I cant get my 7900x to run past 95c even If I wanted to, seems like it just throttles at this temp. How are you even getting temps of 108c?

[@STSYT]

It’s been a while, but I believe to remember that we could just adjust TjMax in bios. Never Z and X boards can do that, and I think that’s also how we did it back then

Does it push 175w on all cores at base clock or boosted clock?.

[@STSYT]

Base, at best. Boost goes a lot higher

[@nigelwright7557]

I guess the outcome is to use a water cooler. They tend to be expensive and also need the right type of case to mount them. I currently have 12600k and that runs great with a tower cooler so cant see me changing soon.

[@cmd.toddwick]

Or, A D15, a Peerless Assassin 120, etc. You really really do not have to spend a ton of money on an AIO. A 35 dollar PA120 will be fine for the vast majority of users. If you work in a naturally hot environment, and while in that environment regularly pump your CPU to its max for long durations, yes, get an AIO, but if the answer to one or all of those is "no", stop wasting money.

[@TheDjarEl]

I have 7900X with AK400 cooler, I can get 5.4 GHZ all cores with a -35 curve optimizer and target temperature of 85 degrees. Cinebench R23 score of slightly above 30000. If I change the cooler I may get 100 or 200 more MHz, this is not a bit deal at all.

[@UnTwoOne]

Great video as always. It's interesting, how difficult it will be for aircoolers to handle 13.gen. It's a bit harder to cool AMD 7xxx series, because of this chiplet design, maybe those aircooler will have better luck with Intel. I meah, Xilence can handle 220W of TDP, it should be enough to cool 13600K, at least on paper.

[@TheDjarEl]

This test makes absolutely no sense. See hardware Canucks vidéo. 95 degrees is a target (frequency is adjusted to match this target, even with the best cooler you can get 95 deg, but with a larger frequency). Fixing the voltage makes no sense with these CPU as they can automatically adjust it to what they need. Only changing the values of the curve optimizer, and the throttle temperature makes sense. You can change the throttle target to 70 deg if you want, with any cooler, and you will just have a lower frequency than with a target at 95 deg. For most applications having 5.2 instead of 5.5 GHz will not be a big deal.

[@SamuraiOfTheNorth]

My noctua NH-U12S-SE managed 97°C in prime 95 stress test after 30 minutes of waiting so I think its ok with me because I just use the eco mode anyway :) plenty of power for me

[@thealien_ali3382]

Shouldn't it be 95c all the time?

[@SamuraiOfTheNorth]

@@thealien_ali3382 not with eco mode. it takes less power and doesnt get so hot. in eco mode it runs at 45-50°C if im just wathcing youtube or not doing anything and only uses 45-50 Watts of energy

[@upgrade1373]

my H115i RGB PRO XT is just able to barely keep it at 95c

[@fmonsterrr]

Idk how I see so many state that the 7900x gets super hot. I have a 7900x with the nzxt kraken elite 360 rgb 3 fan. The highest I've seen it get in full high settings is 70-73c gaming 6hrs. I also have the nzxt elite flow case with 3 big front fans. Idk if I'm just lucky but I never reach above 83

[@Kneedragon1962]

Still waiting for the next gen NH-D15. [sigh]. I do plan a 9ooo series, 16 cores, Zen 5 on AM5, and the plan is to set it to self regulate and clock when & where and how it can, and if it gets to 95 ~ well throttle down already! I don't plan to manually clock the thing up & over-volt it just to see what happens. It's designed to run at 95 and self-regulate to stay about there, when loaded. That sounds fine, but when you manually set clocks and voltages and stuff to show how hot it gets, you're breaking that self management and regulation it is designed to do. It's a little bit like jamming the thermostat in your car and then complaining that it boils. That's the sort of thing Top Gear did, not a real car show ~

[@heirtothethrone000]

The real solution is to get the non X version @65 watts so what if the base clock is 3.7 compared to 4.7 you can still overclock it. I've never been a fan of these big coolers.

[@STSYT]

Sure, it’s always just a question of if you really need the performance

im running the be quiet rock pro 4 with 7900x and yea it does get hot, but in gaming alone its perfecly stable at around 60% - 70%temps. i may need to get a watercooler but i dont like having loud fans in my system. anyone can reccmomend me a quiet water cooler?

Percentage temps? What does that mean? Or do you mean Celsius?

[@paranormalrespectingspirit5190]

Hi, did you upgrade to a water cooler? I am torn to go for a water cooler for the first time ever for my AMD 7800x3d

[@the-patient-987]

But it IS AMD's fault and it's not. They made the heat spreader thicker to make it compatible with AM4 coolers. Look at the delidded temps DerBauer got. They sacrificed temps to preserve cooler compatibility but they may have gone too far.

[@luanphan2706]

You can’t have everything in the world.

[@ThePianist51]

I even think the change to PCIe 5.0 and DDR5 were expensive enough. If they changed the state of cooling people would really be pissed.

[@vladasimovic2732]

I have 7900x with Dark Rock Pro 4 air cooler, H7 Flow case with 2x PWM fans, 140mm front and 120mm rear. Cinebench R23, 10 min 100% CPU workload, temp got up to 94 C. My test show that it is about the case and the CPU cooler. The fans can reduce a few degrees but not much. AMD says clearly that 95 C is tjmax but not the limit for power. So it is a safe working 24/7 temp. without reducing efficiency or risking damaging the cpu.

[@vladasimovic2732]

Just run new test with everything closed. Max temp of cores, 92.9 C, one CCD got to 95 for a fraction of a second. Most of the cores never passed 80 C. So, Dark Rock can cool it just fine, if you have a mesh case with solid airflow.

[@oreasic901]

Same case and same cooler here, confirmed this. I also have 2 case fans, one in front and one in back. Being satisfied with temps I decided to gift my pc 2 more coolers in front, just waiting my fan splitter to arive. The front of h7 case is like ice cold always and pulling in fresh air. That is realy one amazing case.

[@akmid60]

Wondering how the arctic 280 did better then the 360 version. By physics the 360 should be better.

[@TheEchelon]

Same here

[@STSYT]

Because the cooling performance of different coolers in relation to one another can change depending on the amount of heat. This is also not exclusive to Water coolers. Take Noctua's NH-D15 & U12A. Depending on the load, the U12A (can) outperform a D15. But turn the heat up and the D15 will be far in front of a U12. The list you are referring too was created using a 3900x that pushes 135W. And the order of cooler on that list is exclusive for that very specific use case. Change the CPU, change the load, and the order can switch. Keep in mind that the list will not "change" but coolers that perform quite similarly might switch places. We used that list to have an "indication" of what to expect. And because that list would not apply directly to the 7900x, we removed the actual numbers. I pulled up the excel sheet where I have all the cooling numbers for all Ryzen 7000 chips. The 360 vs 280 problem comes up with those chips too. Temp normalized to 23°: LF 360 7600x -> 76,4°C ( .4°C better) LF 280 7600x -> 77°C LF 360 7900x -> 82,9°C (.5°C worse) LF 280 7900x -> 82,4°C So if I would have created "real" benchmark lists for every cooler in combination with every Ryzen chip, depending on the chip, the coolers would have switched places. For any benchmark charts that you see out there, you should take them only as sort of an indication how a cooler will perform compared to other ones. But it's never an exact value if you do not happen to have the exact same system. Most of the times such a list will be somewhat accurate. But keep in mind that things might be open to minimal changes. I've seen a dozen Reddit posts of people asking about a LF 280 vs LF 360 comparison. Then someone posts my video under it, accompanied by an army of people referring to Gamers Nexus video and calling me out for not having 1-1 the same results. What everybody forgets there is that GM pushed almost 200W through their coolers, we are doing (only) 130. And what can happen here is that the results at the top end will start to get squished together and sometimes a bit blurry. I did my very best to find an example for this other than myself as a source. Surprisingly, I did not find a single person that did a complete Arctic Lineup comparison using different loads. The closest thing I could find is Anandtech and their LF 420 Review. They did a bunch of graphs at different loads using various coolers. images.anandtech.com/graphs/graph16427/120490.png -> 200W images.anandtech.com/graphs/graph16427/120491.png -> 250W images.anandtech.com/graphs/graph16427/120492.png -> 340W Ignore the LF 240 and keep an eye on the LF 420 vs Alphacool 360. For 200W, the LF 420 had the first spot. Not by a lot though. For 250W, the Alphacool took over. Again by a tiny amount. At 340W, the difference became quite big. And this is the exact same thing. They switched places because the load changed. But, the trend of the graph is still applicable regardless of the load. At any point, both coolers were at the top, and a lot better compared to the last few ones. Just don't take these numbers 1-1. Look where they stand +- compared to everything else. Sorry for the enormous answer. I'm shocked myself. Just got this question way to often over the last few months and wanted to answer it once and for all. Hope this helped :)

Strange BIOS setups for these chips. I'm wondering already if they'll be like the 5800X. It was discovered that the 5800X is overvolted by most Mobo makers. If you do a negative voltage offset on a 5800X and manually set the PBO to +200, they will boost to about 5.1ghz and still run about 8 to 10c cooler on my NH-U14S.... I'm wondering if the same will apply to these new Zen 4 and they are simply set up crazy. I predict a wave of undervolting videos for new GPUs and CPUs.
