Ryzen Fan Videos
« on: September 07, 2023, 04:32:48 am »
Is there some reason why you would not want to enable throttling at a high temperature just so your system doesn't reboot without flushing drive caches? (That is just in case it got that high) This screen is like my ASUS B350 Plus but is not. You can see at the bottom there someone put in a very conservative setting, I was saying before with my 5900X and a GAMMAX 400, I noticed I would not be able to get rid of the heat, but it mostly works with limiting the Boost Override to a max of 105 watts and max boost frequency of 4.8Ghz. Also I notice 100% cpu load has a different amount of heat with Blender for example than Prime95 is hotter. Again I get 72C max with 100% blender cpu load. You should also watch out for the dimensions of these huge fans you are getting if they hit anything. Really bad idea swapping mount hardware and I would not advise using the center clip for a massive hearsiink, Mine actually does use the center mount like that. It actually has been kind of bugging me since I got that cooler that the retaining clip could snap unlike the original Wraith cooler. That is my computer below. One of the fan LEDs seems to have died and I hope that is ok.

For practical scenarios? I know none.

For benchmark wankery? To be effective, throttling must kick in at a temperature lower than the thermal shutdown temperature. The consequence is losing the very top of the temperature scale, because CPU will never operate in it with throttling. So to squeeze the last cycles out of the hardware, one can’t have this enabled.
People imagine AI as T1000. What we got so far is glorified T9.

Your heatsink is mounted backwards. The fan should push the air through the heatsink, so the PSU/back case fans pump the heat out.
You're running a beefy RTX card + 5900X combo... in a 2005 case?
C'mon, also get a decent case that provides better airflow. There're plenty of NOX cases for $50, with 5-6 fans.
You can get a cheap liquid cooler for $50 or so, they do work pretty nice as the heat is pumped out of the case much better.
Still, modern cpus spike a lot, the dies have gotten smaller so the power can't be evacuated so effectively as older (larger) cpus.

In any case, 72ºC is perfectly fine, newer Ryzens are even worse, they boost all the way up until reaching 95ºC and only then they start slowing down!
90% of computers running stock coolers work at this temperature under load or even higher, it's not a concern at all.
Rising the power of that Ryzen might get you into 5GHz, with much increased power and temperatures, the gain will be marginal.
My i7-3770K ran at 85-90ºC for 10 years, no problem, this was due Intel using crappy thermal paste used instead soldering the die to the IHS like in previous generations.

Any modern CPU can run naked, they will throttle down as required to avoid getting too hot, this is not like in 2000s AMD Athlons where they burned down miserably.

Minor question to the OP how much airflow in and out does that case actually have? Unless it is a lot more than the photo shows likely you are pumping recirculated air past your 5900X instead of fresh cool air.

My 5900X (was 3700X) in the since dust removed case also runs a pair of 180mm fans in the mesh fronted case feeding air in so it handles Aussie Summer temps easily. Coolermaster H500P case btw.



Found a Bench test result I ran with some temperatures shown during the run.

What happened since my message was I noticed that red LED on my fan came on and that lead me to believe there could have been a loose wire. So I took off that old fan and checked it out. There was no obvious problem, but the build quality was pitiful on that fan. My guess was it may have been a bad solder joint, they looked bad. I myself had to solder some LED leads that were just dangling because they were not soldered and they were all nearly shorting out. So I was at the store a while back and thought I should stock up on another cpu fan and got a Corsair one. I just said why not use some decent stuff NOW, and I can get another fan later. So I changed them out and the Corsair does seem to be working pretty well. Here is the new fan and the benchmarks for blender and mprime. All below 80C I think. Mostly well below. Can PCIe transfer cause CPU heat? I was doing GPU render on blender with like near zero CPU load and it was still getting hot.

I admit I take the side panel off when I make it do something intense. What I do like about the case is you can't possibly get a drink into it. Oh well. I don't really understand about the heatsink. The cooler came that way so I think you are saying of the 2 ways I could have put it in, it is the wrong way. Well I would prefer to keep all the cables away from it. I was running blender for animations when I was away with the panel on and I noticed the whole system was like 120F. It works a lot better with the panel off, but I got scared my caps etc would die early so I hope there is no damage. That is when I was using the 2600 and not the 5900X.

That heatsink is rather small for a 5900x.
If the fan is sucking the air from the radiator, change it to the other side, fans are much better at pushing air than sucking it.
If it's pushing the air into it, you're having a fan battle.

5900X should draw max ~135W at stock
Gammax 400 is rated for 180W TDP.

If you disable PBO, undervolt, etc. you won't come close to 100W and get similar performance.
Think turning on ECO mode 105W does a similar thing, if its available.

Well I feel safe around 75C for a CPU for a lifespan. By setting the wattage max to 105 I was limiting the boost rates I was going to get. Really what I found is at 105 Watts and 4.8Ghz max the cpu acts pretty much like it is in the specs, but not what AMD seems to want it to do. Running blender I think I got 3.8ghz on all cores, which is actually 100mhz more than the CPU is speced for. So I am pretty happy. My memory is just 2400 memory with a good CAS. Actually is it 3200 and 2400 I run as 2400. But if I made it any faster then I would just get more heat out. Because I am like 2 or 4 rank dual channel I get like what memtest claims is 30Gb/s memory transfer which sounds pretty good. Mine was also the GAMMAX 400 V1 which may be slightly different. It is working better with the Corsair fan.

Yeah I agree, they crank the power to get the best benchmark numbers, similar thing is seen on graphics cards with ridiculously high TDPs. For the average person it should have just been left in a stock eco mode, then have the toggle for those that want it.

The memory though I doubt it will increase power consumption any significant amount. A stick of DDR4 should be less than 2-3W. Going from 2400 to 3200 can increase performance 5-15% in games, so if its stable, its worth it.

There is also some more speed to be had with Ryzen if you do some manual Memory tuning. I gained around 7% when I built this system with a 3700X in it over stock timings.

Reality is it is time for the OP to buy a new case you have OUR permission  :-DD

I never had one of them but I think the bull doze era of AMD had even worse TDPs. Recently I upgraded my second computer for somewhere around $80. I got a i5 3570, 16GB of DDR3, and an ASUS board for a CM6870. The board has almost no advanced settings, but it seems to be set up the way I wanted. So far the board works great except when I enabled like all the C states or whatever I got hangs, but it seems to be fine without that. Also there are some scratches on the board right where you would drag a GPU out and I hope it is ok. I am guessing that is NIGHT and DAY to the bull doze. But also that system does Pcie3 and has my old 1660 in there so it can do stuff when I am away. That is my plan is not to leave my 5900X on when I am gone.  In the Linux dmesg Linux complains about the CM6870's APCI information saying there are unknown or wrong elements in it. It has the latest bios. The CM6870 came with a 3770 originally so I assume it always would have supported my CPU. The owners actually sold off the 3770 and I got the 3570 from someone else. Those pictures are from my no2 system. Both computers have HVR-1800s which get OTA HDTV in Canada as it stands (ATSC 1). Although I probably will never use no2 to record that. It is one of the HDTV cards supported for Linux.

Modern CPUs are thermally governed, the better cooling you have the faster they'll run and the longer they'll spend at full speed. They're otherwise designed to sit at the throttling temperature all the time.

Sort of.
CPUs have a 1 to 3 year warranty, depending on the sku. If they test at 95C and a percentage of processors fail withing that accelerated life testing, its up to them to determine if that is an acceptable number or not. It could be 0.1%, 1%, etc. who knows. Real world stats sees failure rates for intel CPUs in the 0.2 to 1% range (Puget), I'm not sure if this is in a 1 or 3 year timespan. I didn't see AMD CPU numbers.

AMD GPUs have been claimed to be safe to run at 110C. We know the GPU failure rates in general are much higher, up to 5-15%. So no, I don't really trust AMD in telling me what temperature is suitable for my use.

I would gladly trade off the <5% performance hit that you get from dropping to reasonable temperatures and power efficiencies. Depending on your kwh power costs, it might even be worth it to buy a higher tier CPU with more cores, and run it at lower power cap.
