I noticed a number of sites and channels are reporting that the AMD Ryzen 9 3900X 12-core, 24-thread processor can be run at full clock speeds with just 1.00V on the CPU VCore. I just had in my hands a 3900X with a Gigabyte ATC800 cooler, no matter what i did with the themal paste the cpu gets to 90°C on OCCT power test no AVX, ⦠Modern gaming PCs can be incredibly powerful, and incredibly power hungry. AMD ryzen 3900 running too hot and shuts down Hello, I encounter a very strange behaviour. The machine is deffo running hot, the stock fans are noisy (i have the Corsair Pro's to install when I have a chance) and it's really bugging me. Priced at $500, this processor is very strong competition for Intel's Core i9-9900, which only has eight cores. Running wires isnât always practical, but you can use powerline networking to get Ethernet near your Roku if you donât want to run wires. Then they run hot. When gaming itâs about 70C. 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. I have a 9900k and it has the same "qualities". Iâm going to put in a liquid cooling in. NOTE: The 3950X is a 16 core processor while the 3900X is a 12 core processor. Idle is between 45C-55C.

CPUs as well as the ⦠I just built out a new PC and using the stock fan for the 3900x. From what I read from 3900x owners, the cpu is near max OC at stock and runs hot. The Wraith cooler (I have one that came with my 2700x) is a good cooler that serves the purpose. It seems that NZXT is reporting the liquid cooling pump speed at ~10K RPM. My Setup: Gigabyte Aorus Elite WiFi (f11 Bios, the latest) Latest Chipset from AMD AMD 3900x Corsair H100i v2 Windows 10 64bit Updated The first couple of days I had my cpu it was idling between 30c - 40c and under gaming load 60c - 70c Now though under same conditions itâs idling between 50c - 60c and ⦠That shiny new graphics card pushing pixels onto your display might be fast, but it could also get hot enough to fry an egg. Check your voltage if you run high temps on idle!!! But both have 105 Watts TDP. I realize temps are a very loose - but was curious what other folks temp ranges were so I donât go ⦠Low 50s on idle. Ryzen 3xxx CPUs tend to run at veery high voltage even on idle. Would you check how fast the fan blowing through the radiator is running? If part of the issue is unstable wireless, using a wired connection helps. Like way too high. Never before have we seen such power on a desktop platform. When I ran Blender on a large render it was running hot at 92. But a wired connection also causes less heat than wireless. So maybe with the 3900X processor you can use a 280mm Radiator might be what you need to keep it from overheating. Itâs not as fast, but itâs faster than 54-megabit ⦠Good cooling is a must.
