I play games at 5120x1440 with all settings on ultra. It is capable of displaying a temperature of each individual core of every processor in your system! I finally got my PC build put together and am going to run Prime95 (small fft) the rest of the night to see if it's stable. I don’t know if these temps are unexpected or out of range for the 9700k? ASRock X370 Taichi. Few seconds on prime95 smal fft and the 3900x goes to 75C. But it should not ever come close to that in normal day to day. Default bios fan curves had me at 70-71 while gaming with MSI game boost enabled in the BIOS. Re: normal 3900x temps I had the same issue on day 1 of my build, the fix, which I found here, Change from Ryzen Power Plan to Windows Balanced Power Plan. The heat density is the issue, as the cores are packed into 7nm chiplets, and the rate that the heat transfers to the IHS (internal heat spreader) becomes more he rate limiting step. Basically no difference. Doing some benchmark with Cinebench R20 . It will show the voltages/timings/etc it's a useful software, or even RM does the job. Recently upgrade to a Ryzen 3900x with a GIGABYTE X570 AORUS ELITE WIFI Motherboard. I'm using an MSI X570 Pro Carbon Wifi with my 3900x. I’m going to put in a liquid cooling in. I just built out a new PC and using the stock fan for the 3900x. I think there is something wrong with it. Battlefield 5 1080p ultra never goes above 65C. Prime95 will hit that temp on a stock cooler. So I want to know if it's something wrong or those are usual temps for Ryzen on air cooling. Prime95 Smallest FFTs (high heat): 82C Prime95 Small FFTs (max heat): 87C Temps jump up instantly, then when I stop the test they instantly drop back to idle ~32C. The highest temperature was 75 °C with the Ryzen 9 3900X during Prime95 Small FFT. Or I seated things poorly. To clarify a bit on what has been said here: The AVX downclocking is different between Intel and AMD. I am running it on X370 auros K7 board with 32gigs(3200) memory. So with a bit of research I dial it back all the way down to 1.275v. Prime95 temp: 79C. Ive got a query with my temps on my Ryzen 9 3900x, I think its high but can i get a few second opinions & maybe some advice from you guys? have the vcore set to 1.32 in bios which isnt too shabby and its plenty stable. I even run 1usmus Custom Power Plan but same temps. Cooler is fine. Or if my AIO water cooler just isn’t holding up anymore? Core Temp is a compact, no fuss, small footprint, yet powerful program to monitor processor temperature and other vital information.. What makes Core Temp unique is the way it works. Idle is between 45C-55C. I'm new to AMD CPUs so just want to make sure everything is looking good. After the upgrade, noticed the stock cooler for the 3900x whirring up a lot randomly and then calming down. I would think those are stable clock speeds. These are numbers from HWInfo x 64. continuum. Hey Guys, I recently made a 3900x build together with a Gigabyte x570 Elite and a Noctua NH D-15 , but it kinda bugs me when i check the temps on the CPU. According to HWiNFO64, package power has dropped to 120W. I recently got a ryzen 3900x for my 3d workload. For the Ryzen 7 3700X, the Wraith Prism RGB kept it at 66 °C during P95 small FFT testing. I initially had my i5-2500k OC'ed to 4.6GHz, but noticed that ~30 minutes into the stress test Real Temps was getting upper temperature readings of … I am running everything at stock and am very happy with the performance. I just built a new liquid cooling loop. Which got me looking at voltages and the BIOS had the CPU at 1.45ish for god knows what reason. Hi Guys! My 3900x sits at 4.2ghz all cores. Moderator ... 3900X with a Corsair H115i Platinum, Gigabyte AORUS Master BIOS 12g. So, when you will set a range by entering numbers in min and max fields, Prime95 will go through all the numbers that will fall within the given range. I was running Prime95 no errors for about 4.5 hours with the max power/heat option and it got to 90C with EVGA CLC 240 cooler. Popular Reviews. Idle temp … Ik zit met een 3600 @ 4.2 Ghz all cores idle op zo'n 37 graden en stressed 48 graden, AIO = Kraken X62. My temp dropped down from 55-60c idle to 35-40c and gaming from 90-95c down to 75-80c max after 4 hours of gaming ( it runs at 65-70c in the first 2 hours of gaming). It has its own list of sizes that it can use. Have a Ryzen 9 3900x Full Stock- no overclocks- running in a full custom loop, 2x 1080tis in the loop after it. However the only thing concerning me are the temps. Temps zijn wel hoog! Thanks. What are your opinions? I also tried running CBR20 with those settings and with higher voltage to check for false clocks, and it turned in a score of 7040 both times (3.9 GHz is not that fast folks), so I wasn't getting false clocks using the voltage settings that got me 1.056v in Prime95 … Since the software makes heavy use of the processor's integer and floating point instructions, it feeds the processor a consistent and verifiable workload to test the stability of the CPU and the L1/L2/L3 processor cache. My 3900X does not even hit 95 anymore on Prime95, it did with the stock cooler and even high end Noctua Air Cooler. F@H Desktop: i7-5960X 4.4GHz, Noctua NH-D14, ASUS Rampage V, 32GB, RTX2080S, 2TB NVMe SSD, 2x16TB HDD RAID0, Corsair HX1200, Thermaltake Overseer RX1, Samsung 4K curved 49" TV, 23" secondary Running 5 minutes prime95 Small FFts hitting 84°C. Hi. Re: 3900x Temps - Cinebench/Aida64 Higher temps on the same cooler are normal for the 3000 series vs chips with the same TDP from the previous Ryzen releases. Two 140MM intakes pulling fresh air in the front, cooling the radiator. Download Prime95, For overclockers, Prime95 has a feature called "Torture Test" that allows maximum stress testing on the CPU and RAM. These targets and hopes are somewhat based off our success with overclocking the Ryzen 1st and 2nd Gen. CPUs as well as the Threadripper processors, which you could argue are more akin to the 3900X. Ryzen 3900X with a Corsair H100i rad and MX-4 in between. At idle, temps are 32C. Note: Prime95 cannot go through a completely custom sizes. update : and yes, 3900x 4.3Ghz with 1.2V run prime95, after 6 minutes my PC restarts but after lower cpu ratio to 42 i can run prime95 10 minute avg temp is 62, but after 7 minute, temperature are climbing to 88.3c (it looks like if I continue the test more than 10 minutes the temperature will continue to rise, * the number behind the comma *) Re: ryzen9 3900x temp increase to 95 c when rendering Jump to solution Hi I see this answer's been around for ages and wanted to include my own for anyone else who sees it as I don't think it's hitting on the most likely scenario based on what I've read elsewhere and experienced with the 3900x. How long do you prime95 on your systems? When gaming it’s about 70C. I am coming from 1700 with an AIO and these 3900X temps seem high for the Arctic Freezer II 240 which in all reviews performs like a champ. This shows that the stock cooler is adequate for the 3900X at stock settings. Prime95 temps only hit 70C weirdly enough. Can someone tell me what I should be getting running small cpu FFT’s with Prime95 … It’s stable, but these temps sure are high. Granted, een 3600 is geen 3900X… Temps are slightly higher now @ 53.8C but holding steady. Prime95 uses the min and max limits to cycle through all the FFTs within that range. I recently purchased a used 3900x for a new PC build. Download the ZenTimings and post a print of it. When I ran Blender on a large render it was running hot at 92. For cooler I am running a Kraken M22. Using Cinebench to put 100% load on the CPU results in temps at 79 C. ok thought id push my e7200 upto 4ghz and prime95 test it. I just noticed that temps were idling at 70ish and immediately hitting the 95c thermal limit on load. Prime95 has been a popular choice for stress / torture testing a CPU since its introduction, especially with overclockers and system builders. I notice something funny is when the computer is idle the voltage at 1.45-1.46 V and temp is around 45-55 Cel. I'm running the 3900X with the Noctua NH-D15, and that also jumps around in temps and fan speeds, it's done this on multiple different Ryzen CPU & motherboard setups, it's perfectly normal. I realize temps are a very loose - but was curious what other folks temp ranges were so I don’t go full OCD on temps. When i started doing the benchmark, the Voltage drop to 1.3- 1.4 v. The CPU core is at 4.0 ghz on all cores. The 3900X ships with a base clock of 3800MHz and a single-core boost clock of 4600MHz, so a reasonable target, with a sensible boost to voltage, would be around 4.3 - 4.4GHz across all cores. Well, all I can say about your temps then is they are great.

Idle is about 53C. And fins are mildly hot so it's doing his job I guess. When I put load on it, temps instantly spike up. My AIO is the Thermaltake Floe 360. i have a 3900x at 4.4ghz under a 360mm ek custom solution and my load temps are around 75 degrees, tbh i can push 4.45ghz but temps do go past 80 so for so little clock gain its not worth it, most 3900x under all core clocks top out at around 4.3-4.4ghz so what you and i are running is pretty much what is to be expected from that silicone. But I avoid having RM installed so I ZenTimings and HWiNFO64 to monitor sensors.
