Have you noticed unusual performance in your computer's processor?
I've just assembled my new build, but I've seen the 5800X3D running hot, often around 83°C with peak temps hitting 90°C during tasks. I'm not sure what's causing this or if it's typical. (Thermal paste was applied.) I have three exhaust fans and three intake fans. CPU: AMD Ryzen 5800X3D Cooler: Corsair iCUE 100Hi Capellix
The current temperature is unusually high—check the cooler attachment. Ensure all fans are running properly. Have any overclocking changes been made?
I'll review the mounting in a few hours to confirm anything unusual. I'm certain there was no plastic, which was the first item I took out during setup. I'm still unsure about other possibilities but will revisit this later.
Another chance is that you received a faulty unit where the microfins are stuck together. I haven’t come across any Corsair AIOs with that issue, though it might be possible in theory and could happen if the mount appears to function properly.
My 5900X operates between 36°C to 38°C. The 5800X3D uses two-thirds as many cores and threads, which suggests it should be cooler, though both models run on 105W chips. I’d appreciate seeing the specifications and images—details like the case, coolers, etc. If you own an AIO with a front-mounted radiator in a solid-nose chassis, that’s likely part of the issue. Generally, optimal cooling requires 2–3 intake fans, one exhaust fan at the back, and 1–2 at the top. Updated January 19, 2023 by An0maly_76
My heater is installed high up and the housing I'm using is a Corsair iCue 4000X. It has three front intake fans, one back exhaust, and two on top are also exhausts. This photo might not be useful right now, but it shows what appears to be the setup until I can capture a clearer image with lighting and no glare.
I’d verify the fan placements carefully just in case. A piece of paper could easily be carried away by a fan exhaust and drawn into an intake. Besides misaligned fans, it seems the CPU plate might not be firmly attached, there may be insufficient thermal paste, air blocking the flow, or the cooling pump is weak. Also, inspect the radiator and hoses for hot or cold areas—ideally use an IR or laser heat gun to measure temperatures accurately. By the way, what model are you using? A quick note: I initially considered the Asus B550M-K for my 5900X, but it was advised to switch to the Tuf B550-PLUS or Tuf B550-PRO because of their lower VRM quality. I also question if that’s why performance dropped.
I've experienced automotive heater cores with a one-way control valve. It's unclear why the maker would require this for an AIO, but it might be relevant here. If the radiator has a similar check valve and the pump resists it, the fluid won't flow properly, leading to overheating.
