I wrote too. This was my thought as well. idle is about 30-35C, "Is it possible to tame the heat of the 3900X? Prime95 with Small FFTs almost instantly overheats. AVX workloads probably need a lot more voltage than non-AVX. Though I'm using an AIO, so my results aren't directly comparable. Now, as per instructions, I mounted the block in a way that the inlet is center and the outlet port is "up". Review of the year 2019 & 2020. On a single thread I could get 4.3 out of it during testing and about 3.9-4.1 all core depending on the test. i.e. The trick is 90degree rotation: by default all AIO / water blocks split the flow (verticallly, since they are expecting center die) so technically your using half the flow / surface for cooling the cores, 90 Degree rotation would direct 100% of flow/ usage of the entire cold plate. Hardware. Are there any updates on a revised jet plate for the HK IV? thermal throttle.

Wassim Aouadi. 1st impressions are not that good, I remember when NFS used to … There are several factors which can affect this, such as room dimensions, heating levels and types of window, which are all covered in our radiator BTU calculator. Honestly, as much as it pains me to say it - unless it's throttling somehow or affecting performance... just let the hotspot temps hit 80-90C. In order to further reduce the heat output in the spotlight, 12V low-voltage spots can be used. For this we just need a pic from the other angle to see the fans. Any updates or insights you can provide from the tests so far? I don't know what the jet plate looks like and I'm not gonna disassemble the block (and have to drain my loop) if I can avoid it. I finished building my custom loop for my 3900X just over a couple ago and the temps are a bit disconcerting. The TDP is a rather tame estimation of the heat output of the processors when it comes to Intel. We had to lower our voltage over and over again to keep it from overheating when fully loaded on all cores. All forum topics; Previous Topic; Next Topic; 1 Reply fyrel. I'm aware of possible air bubble problems so I'm skeptical myself. The default value 142 95 140 are bad it sends too much voltage but core clock cannot boost higher becuase its limit by cpu temperature itself so you got more voltage for no reason and running hot. I am not wrong, you definitely need to watch that video if you are going to suggest AIO orientation. In the end, our maximum overclock of 4 GHz is disappointing compared to what (low-threaded) boosts we would see from even the stock … Power Usage. There seems to be a problem with the heat transfer to the block. The 3900X could be the new CPU king Here's a killer gaming build. This is wrong. Built to Perform. Hello Jakob, any updates with regard to the CPU blocks? Try auto and see what your load temps are like then. That’s where the somewhat marketing-driven TDP figure comes from.By the numbers, Intel’s 9900K is the more efficient chip, with a rated TDP of 95 watts, while the 3900X has a TDP of 105 watts. The biggest hurdle with Ryzen 9 3900X is its massive heat output that managed to overwhelm our 240 mm AIO watercooling, even with slightly reduced voltages. FATALA-VM SPA. General Hardware .

I would recommend your other cooler for sure if you can find the AM4 mount kit for it. Even with a 240 mm all-in-one water cooler, we couldn't even get close to what it can do. Thing is, These run better at Stock or PBO. Highlighted. Trying out NFS Heat performance on my Ryzen 3900x/2080 Ti, video is 1st two races in the game. It would be really cool for someone to test this out and measure the performance difference, if I didn't have to drain my loop and refill it, I would definitely give it a go today. I did not fiddle with voltages. Will appreciate any comments. It's not the pump location per say, it's where the top of the loop is located. AMD has been enjoying quite a year; with the release of the Ryzen 9 3900x and 3950x, the company has done an amazing job at bringing higher end processors in the market. Cookies help us deliver our Services. to make an informed diagnosis. At the least, a single bead in the middle doesn't appear to work as well as before, because there are now multiple dies under the heat spreader, instead of one central die. This is of course, still following the installation instruction of the Heatkiller IV Pro for AM4, so I am wondering if my temp issues are potentially related to this, or is it simply impossible for the 3900X to dissipate it's heat onto the package fast enough to avoid thermal issues? For PC on the PC, a GameFAQs message board topic titled "9900k or 3900x?" For the CPU, I am using a Heatkiller IV Pro, and my concern here is that the cooler is not mounted with enough pressure because there is a tall plastic washer between the mounting screw and the motherboard. I'm on the Crosshair VII Hero which only has 1.0.0.2 AGESA atm. 0 Kudos Share. I don't think I'm gonna OC my upcoming 3900X at all, seems like a winner right out of the box. In the words of Der8auer, the new chips possibly have hotspots, I assume the cpu chiplets. RE: UPS heat output IRstuff (Aerospace) 16 Sep 04 00:14. I have three 360MM XE 360 radiators with 3000RPM fans attached to them. Peak temperature while stressing the CPU with CPU-Z is about 72C, and repeated runs of cinebench r20 can get the cpu up to 80C. We will let you guys know if we will release a Ryzen 3000 dedicated cooling solution. Use Precision Boost Overdrive to reduce the limit the power instead of extend it. In a low-voltage recessed spotlight, the only power loss occurs in the LED chip and in the driver. When I first got my 3900x I set it to 4.3 all core in the BIOS, I tired 4.4 but it would not boot. Just … The Ryzen 9 3900x is the perfect and high-performance processor with 12 cores and 24 threads. I set it back to normal and it would clock to 4.25 at boot but raise and lower as needed. So, you do not have to worry much about it. So I turned on PBO, set the PBO scalar to 10 (max) AND applied a -0.1V offset. It will slightly reduce the effect of gravity this way. Keeping your components cool is a concern for any builder as it impacts performance and longevity of many of the parts of a PC. Ryzen 9 3900x Voltage and Temperature. So it's a good idea that you wanted to lower the heat output somewhat, this CPU is getting quite hot as it is. Welcome to TechPowerUp Forums, Guest! In order to ensure the processor doesn't overheat with heavy multi-threaded loads, we used the same CPU voltage as in our original 3900X review: 1.225 V. While that is quite low, it's the best we can do with the 240 mm AIO. But that’s not the full story. I think it's possible to get good temps with AIO / custom water blocks. Didn't happen with my 3900x and NH-D15 when I tested, they were gone only at the center, not at all about 5mm from the edges and only partially near the cpu chiplets. If OP disconnects the fans connected on the top of the case and connects them to the back of the radiator, that is, if it uses the radiator with 4 fans, it partially prevents the processor from blowing hot air into the case, and may provide temperature gain up to 10 degrees. Based on the 754 watt figure, BTUs/hr = (754 watts * 3600) / 1054 = 2577 BTUs per hour, per server. Forums. Efficiency isn’t as important on desktop chips as it with mobile, as there’s no battery life to be concerned with. Fans need to spin up higher to better dissipate the heat. I dont have an AM4 watercooled, so I cant help much more. Maybe I'm wrong, maybe not... You're writing whatever comes to your mind. Heat output is measured in British Thermal Units (BTUs) - 1kw/hr = 3412 BTU/h or 1000 BTU/h is around 293W. If possible, get a PSU of 700 watts or better. 4) Unfortunate i can't mount the radiator on the top of the case because the memory is in the way. the extra <10% clockspeed and +-5% ipc in games isn't really worth the gaping hardware-level security holes every few months, or the 33% less cores, or the higher power consumption and higher heat output, or any of the other Intel bulls***. Enabling PBO still saw the 3800X run around 2-3 degrees hotter but now it’s only clocking 25-50 MHz higher than the 3700X, so if you want to turn your 3700X into a 3800X, just enable PBO. I also have a 3900x, which stock scores around 7k in r20, or a hair under. This can also present a challenge to the end-user in terms of the choice of components. Especially if your gpu (assuming in the same loop) stays at 40. #Noctua #CorsairH100X #Ryzen9 I changed the Corsair ML120 premium fans on the Corsair H100X AIO to a couple of Noctua NF-F12 Chromax 1500rpm fans. I used GTA V for testing because it consistently was able pin both the 3950X and my 1080Ti at full power. (Maybe this is not the best advice, and feel free to get other opinions.) Didn't take long for the PC to shut itself down. ARUN-T. ARUN-T. I'm sure that it could probably clock higher, but the PBO algorithm still needs tuning. You do the undervolt and you will drop 10% of the heat output compared to stock. Designed to Win. This is the “heat output range” which can be achieved by the stove. Going above what the processor will boost to will require more sufficient aftermarket air or liquid cooling. For example, the 9900K which has a reputation of being an inferno, has theoretical intensity of ~1.15W/mm² when operating at 5.0GHz (200W @ 174mm²).Meanwhile Matisse can easily reach intensity of > 1.5W/mm² (120W+ @ 74mm²).
