Hi everyone,
I was gifted a Supermicro H8DG6-F with dual core g34 AMD Opterons cores by a friend to create a rendering computer. I'm very much an amateur with anything server related, but have been determined to get the PC build to work.
However, after numerous trials I've been unable to resolve my issue. My MB uses automatic fan control (only available for 4 pin fans) in combination with a BIOS setting (4 modes, performance, high, balanced, energy efficient) as a way of controlling fan speed. I work in a quiet co-working space and need the rendering PC to be reliably quiet. For cooling, I'm exclusively using Noctua 4 pin PWM for both my heatsinks and a few of the case fans. My computer at idle is incredibly quiet, which is wonderful.
However, any time I render anything (either GPU or CPU) my computer will stay nice and quiet, and then, out of no where, ramp up to sounding like its going to explode. I've downloaded a few tools to try and monitor fan speeds but unfortunately I'm not getting any readings (CAM, Openhardware) so all I can provide are guesswork RPM readings from my BIOS. I would say that at idle, my fans are spinning around 400 RPM ish, and when I render, they continue to hover around that range, until they all simultaneously ramp up to 1600 RPM at once and create a lot of noise.
The interesting part is that when they ramp up, its only for about 20 seconds, then they go back down to being perfectly quiet (while the render is still happening). Then, after another minute, they'll again ramp from being perfectly quiet to max RPM for 20 seconds, and go back down, in an endless loop until I cancel the render
Based on reading these forums, my understanding is that the BIOS thinks the fans are running too slowly because they fall below some RPM threshold so it hits them with 100% duty until the RPM recovers. The temperature control takes over again and the RPM falls based on the PWM sent to the fan and the process repeats.
I want to confirm that this is indeed the problem, and if it is, kindly ask that somebody might be able to provide a way of fixing the issue. I contacted Supermicro but they were not very responsive. They told me I could "use a third party ipmiutil tool if I desired" to fix it. I saw a couple of ipmiutil commands floating around the forums, but because I am very inexperienced in these matters, I was apprehensive about using one of the commands incorrectly and messing up my machine. I am using Windows 10 pro for OS
Sorry for rambling and thanks everyone for your time. Any help you could provide would be hugely appreciated!! I have been struggling with this issue for months.
