That's within range of most cooling solutions I'd think. You guys are fine with those temps, as long as it's not throttling (85C at least on my last CPU, 2700X) then it really doesn't matter. But if you do another build, consider big air. I just pieced together this 5900X rig of course, was always curious about the D15, and am shocked at how it performs.
Thanks for the reply. I'm sure your Noctua is a great air cooler but I seriously doubt it will cool better then my Capellix 360 AIO. Are u running the Newest Prime95 with AVX instruction test? The temps we are seeing are with AVX enabled. My CPU idles in the 20's-30's with Ambient room temp at 72-75F. I stay in the 50's with most tests/tasks but if It's something with AVX, that is where the CPU will spike in temp
I just checked to be sure on my settings, yes those temps are with AVX enabled. I don't want to attack any AIO but my numbers are in a constrained case. Granted I have 5 Noctua fans in there, but some are less than ideal (15x120mm), nothing is setup for any trickery. Stock bios settings etc. Mine are legit temps on what I consider a proper D15 rig. I've seen hwmon record a 71C max, but that's momentarily. I've never caught it hitting over 71C, even for a second, and my fans are set to ramp to 100% after 255 seconds, giving the heatsink a lot of time to get saturated with heat. I do that to prevent tiny blips from making any noise on the desktop. Under load, I can't get this system to go over 61C. At least the hardest workload I know of, Prime95 with 24-thread torture test.
Well then that Noctua is a great cooler, especially in a tight case. I will run some prime95 AVX later and get back to u with the temps I am seeing. I also have a Lian li Dynamic XL so my case is huge, and if you are getting those temps, it is putting my 360 AIO to shame
Yeah I didn't post it to show off or be a dweeb about it. If I knew how to help you guys get those temps down, I would. I was just happy- I have been so impressed with this system that I came to the forum to see what people were talking about in regards to cooling. I always wanted a D15 and this worked out better than I imagined. I'd use an AIO but I know there's a massive difference between different choices and there's a lot going on there, I'm kind of lazy, I want to set things up and forget it. The only ones I've looked at though were the NZXT and I'm unfamiliar with the rest. I took a screenshot of it last time I did a 10 minute run, I did this a couple times to burn it all in. Proof (as good as you can produce at least) because talk is cheap and people lie, but I don't.
Can you post results from CBR20 and HWInfo.
I don't have CBR installed right now but will be happy to put in the effort to get you those. Just eager to see Island's results, and wouldn't mind if you shared yours too- you also have a 5900X.
I just made this post with all details.
I ran this for ya. I don't know if my score is great or not but everything is stock here, nothing is tweaked out. Temps while this ran varied from 56C-59C. Peak of 62C at some blip that I didn't catch as you can see here. While performance could be tweaked out, only running spec 3200MHz on my RAM, but my temps are still (apparantly) phenomenal on ye ole D15! Hail Noctua!
We going to hear back from you? Curious on more benchmark results myself. My rig like all of yours is a new 5900X build so comparing is good. I'm happy with my 8301/612 CBR20 score, but my previously amazing temps appear to be gone now- so rest easy on that front! I'm probably closer to the rest of you. Unleashing the additional 600 points in CBR seems to have unleashed some power limitation that was in place with PBO being set to auto in my BIOS.
Keep in mind that when playing games you will be GPU limited. E.g. running at 4k with a 2060 will make sure the CPU barely does any work so there isn't as much heat produced. If you change the res to 720p and everything to low then your temps will go up so comparing games without everything else the same is apples to oranges.
Posting my cinebench scores in case you are interested. The score of 8359 is stock and 8770 is with PBO and 627 single core with PBO off. Single core score drops when PBO is on, not sure why. Not much gain for a whole lot of watts. Keep in mind that the CPU will throttle on watts. Mine stays at at 195w average. My guess is yours throttles a bit more. The D15 is a great cooler, but once you run PBO with a 200w limit you are close if not above the thermal limit of the D15. At stock 142w it should work very well if noise is not a factor (needs high speed on case fans to provide fresh air vs. a front mounted rad).
I'm pretty happy with my results, I'm within margin of error with everyone else's 5900X, and my multicore is only suffering a bit due to zero memory optimization being done. I'm also on a mini-ITX board, which is surprisingly adequate. To be clear, I like watercooling, I just don't think the additional performance is worth it for me. If you have the space as I do, and you refuse any case that doesn't have a horizontal motherboard layout (GPU sag and any form of strain from components is eliminated), a big chunk of metal and fans makes sense for me.. someone who wants to set it and forget it. I highly doubt in real world use it makes any difference between the best coolers, especially in gaming. My machine only really gets any sort of intensive use when in-home streaming (8-threads in use and the game, Steam Link) or code compilation.Margin of error is generally 1% or at most 2% so around 5% is well outside. How much real world impact it would have depends on the use. My setup is built in memory profile and all else stock, outside of turning on PBO in one run. Manual OC and increasing temp and power limits just dont't bring real world gains that are large enough on the 5900x and it is just better to control the temps as the CPU will OC by itself. That said, I do agree with you that real world gains are generally small outside of noise between air and water on stock settings as there just isn't enough heat at 142 watts or less.I never understood the people that worry about noise. I have my rig to turn all 5 fans up to 100% at 50C+. I think that's why I'm getting such good results. Noctua fans are still definitely bearable at full speed. I also have a pair of Sony WH1000XM4 noise cancelling headphones, but I didn't buy them for the fans.
Nice small-form factor computer setup
That setup will massively improve the performance of the air cooler compared to a normal case though, so it will not be comparable if running a midi tower or full tower.
That's what I found through the course of this thread. PBO while increasing my CBR20 score by about 800 points, shot temps through the roof. Probably power too, I didn't look at that. It basically just takes the CPU out of any reasonable binning limits for not a lot of gain. I assume it's better to leave enabled as most tasks are shorter bursts and not as heavily threaded as CBR20. It does look like you're at 3600MHz on your RAM while I'm at 3200, which is going to make up the sort of difference we're seeing between my system and yours in multithreaded results. I could bump mine up probably, just don't want to.
Running 3200mhz at 14-14-14-36 or something like that would generally perform about equal or slightly better in most cases as long as it is 2x 2rank. Only some cases where 3600mhz with higher latency has a major benefit over 3200mhz with lower latency. If I were to run with OC then I would probably OC once a certain threshold is reached in amps and run "stock" the rest of the way. None of the games I've tried are even close to the 142 watt limit without PBO so makes no sense for me, especially with the possability of the added heat on occasion. However even with cyberpunk running 12-14 threads the boost clocks are still 4650+ so I doubt there are any games where overclocking would benefit and for other tasks it doesn't matter much if it takes 55 seconds or 1 minute. The single core performance drops about 3% in my system though with PBO on so stock seems the most sensible.
From my testing it seems to be the insane voltage they run (up to 1.5v in single or low core loads) which causes temp issues at stock. I have seen as high as 22w on one core and that can easily cause temps to spike to 75+ even if I can easily cool the entire CPU at 142 watts. The CPU is designed to run this hot though and it isn't much worse than what intel has been doing so it isn't something I worry about now, but it was a bit of a shock when first running the CPU in synthetic loads.
It's hard to know the best settings with these things. This is another area where Intel just has you taken care of. I was getting acceptable performance with PBO on "auto" (off). I feel like I've seen single/dualcore speeds drop a bit with PBO on though. I was seeing 5050MHz regularly and I haven't been catching that for a while. Your single threaded point may be accurate and I'm losing a bit of ST performance for the multicore uplift, and using a lot more electricity and generating a lot more heat. In the end, likely I go back to how I entered this thread, PBO auto/off. Hard to know which is the way to go! Only thing we can do is benchmark our own individual usecases, whether it's games or work.
The one issue with this is that the #1 instability generating change for people is fiddling with their RAM. Few to none do the effort of running their machine all night on memtest86 to check for memory stability. Since it plays their little games, they think all is well. It's not. Random issues pop up later on and they wonder why their "software" is so buggy.
Welp, just got a random reboot tonight while doing 8 thread libx264 encoding, so I've disabled PBO. Nothing in the event logs that's useful, no crash dump to sift through. So I can't blame a driver on it, I usually like to point the finger at Nvidia. Probably PBO pushing a bit too hard in some way.
You could try setting your TRC to XMP spec instead of the autosetting that you get with D.O.C.P. Got between 1 and 1.5 percent gains from that in benchmarks. Mine was set to 85 on auto and XMP spec for mine is 58. Did stability testing similar to what I would do with a permanent OC with no issues (about 10 hours worth of tests total). Also made some minor changes to my cooling as well so those two improvements combined has me up to 635single core and 8568 in multicore in cinebench 20 (no hardware monitors running) with only D.O.C.P+trc and rest on default settings. Most of the improvement was from the TRC.
I'll take a look at that. What has bugged me is that there's 3 PBO options in my BIOS.
