  1. Update: So I opened the case and looked inside my Corsair One Pro. The M.2 SSD is on the front of the motherboard and it has the stock ASRock heatsink already. The heatsink looks a bit wimpy to me. If you are interested in what it looks like, you may see it on ASRock's website: ASRock > B550 Phantom Gaming-ITX/ax I am not sure upgrading the heatsink would do much. It gets the hot air from the CPU watercooler radiator. So when the CPU is hot, the SSD gets the heat from its radiator. It has a great performance when it is cool though: I am at the end of the 30-day return period. I think I will keep it. Then I will replace the M.2 SSD in a few years.
  2. I have figured it out. This is what I have done: 1. Have 5 layers of temperature lighting types. 2. For each layer, create a "Quick Lighting Zone" by selecting the corresponding LED(s), the sensor, and the color temperature range. As a result, I have the following color scheme: 1. LEDs 1 and 5 correspond to CPU temp. 2. LEDs 2 and 6 correspond to GPU temp. 3. LEDs 3 and 7 correspond to SSD temp. 4. LED 4 corresponds to CPU coolant temp. 5. LED 8 corresponds to GPU coolant temp.
  3. Currently, I have the 8 LEDs programmed to change color based on CPU temperature, as shown below: I would like to program each LED individually. For example, LED 1 for CPU temperature, LED 2 for GPU temperature, LED3 for SSD temperature, etc. Can someone please explain how I can do that with iCUE?
  4. The top fan and the GPU water pump look okay to me. If it were me, I would open up the computer and see if the GPU radiator is clogged with dust. How long have you owned this machine? Is it in a dusty environment?
  5. If you turn fan to its max speed, does it still over heat? Maybe you can do a screenshot of the iCUE Dashboard and put all sensors on the dashboard when your unit is overheating? An example is shown below:
  6. What are the reasonable upper temperature for the CPU coolant and GPU coolant for A200 when it is under load? In iCUE's Alert tab, one can set the alert coolant temperature for turning fan to max and another alert for shutting down the computers. What would you recommend for these 4 values? 1. temp for CPU coolant to trigger max fan, 2. temp for CPU coolant to trigger shutting down, 3 temp for GPU coolant to trigger max fan and 4 temp for GPU coolant to trigger shutting down
  7. Update: The Cinebench R23 multi-core score for my unit is 23,663, which is a bit less than the average 28,782 shown on some website. So I used HWMonitor to investigate what is going on. I found the core power consumption is limited to 85W. The R9 5950x has a core power consumption rating of 105W. Apparently, it is reduced to 85W to keep the system from overheat.
  8. It looks like I have found another weak point of the system: the M.2 SSD. Without any R/W to it, it reached 69C while I was doing CPU or GPU stress test. The top fan was at 1,200rpm during these tests. I should probably open up the computer to take a look.
  9. For my Machine Learning work (as opposed to Deep Learning work), it is CPU 100% for hours or days, but not much GPU or disk I/O. The CPU stays at 80C. The top fan stays at 1,200rpm. The CPU coolant stays at 48C, for room temperature at 22C. I think the clock speeds, as shown below, look reasonable too.
  10. Good point, LeDoyen. How do I increase the CPU water pump speed?
  11. I don't think USB ports are supposed to deliver power when the computer is shut down. One can change the BIOS setting to deliver power when the computer is in sleep mode, but not shut down.
  12. Did you update the BIOS or change its settings? I think 10-12 seconds seem to be okay. I just got a brand new unit and it takes that long as well. One can disable some self tests in the BIOS to speed up the boot time. But It is probably not a good idea.
  13. Nice repair work! It is good to know that one can replace the AIOs if they fail outside of warranty period! With the stock AIOs on Corsair One, can owners top off the fluid if it vaporizes over time? Your choice of top fan is good. My Corsair One Pro came with that fan, I believe. Can you comment more about how Argus Monitor fan control is better than iCUE? While the current version is iCUE is quite good already for most heavy duty applications, it does not address some of my uses. I need to run some single-threaded software for hours. It does not stress GPU much. As a result, the CPU can run at 90-91C, but the fan speed does not increase. Apparently, the logic in iCUE fan control does not cover some of my use cases.
  14. Update: I believe the fan control software is still buggy. This is not a deal breaker for me. But I hope Corsair can fix it soon. My Corsair One Pro's fan can spin at 2,000rpm. When multi-cores and GPU are running harder, the fan also gradually increases the speed. This is nice. However, for some of my work, the software runs in single thread and runs for a long time, and without GPU processing. As a result, the CPU runs at 91C for a long time (like hours) and I don't see the fan speeding up. This is not a good idea for consumer products! I set the min fan speed at 975rpm. When CPU runs at 90C, I would hope the fan could speed up a bit.
  15. Thanks again for the info. I changed the computation software and now it could drive the GPU to 80% utilization, which is very good. Judging from the low utilization of the bus interface, there is not a lot of traffic between vram and system ram. So the 12GB vram size is probably not a bottleneck, I think...
