Hey folks,
A bit over a year ago I bought an MSI Aegis RS series desktop because it came with an RTX 3080. At that point you couldn't get an RTX 3080 anywhere for love or money. Historically I've built my own rigs from the ground up, but this had decent specs out of the box--and that 3080. It's a mid-tower case though.
I immediately added an NVME drive (Samsung 970 Plus) and set that as the boot device/Windows volume. I also replaced the 16 GB of RAM with 32 GB of Corsair memory. I made both those changes within 2-3 weeks of receiving the PC. Everything has been running wonderfully since then. There haven't been any other hardware changes.
But in the past two-three weeks, I've been getting crashes or summary power shut downs, increasing in frequency. Either the system hangs and is unresponsive to all input (except the case power switch), or else the system literally powers itself down. This even happens when I leave it on overnight - I guess the Windows backup process or a scheduled virus scan must be pegging it.
When I'm watching, I've noticed that when this happens it's usually under load and the fans are going faster than usual. So I stared running HWMON and realized that the CPU cores are idling ok at around 41 to 44 degrees Celsius, but under any kind of load--from a relatively light-weight 3D game to a complex Word doc, or rendering video--they flare up and hover between 80 and 100. During video rendering or gaming, all cores routinely report 95 to 100 degrees Celsius.
I've tried contact MSI's support since it's still under warranty. Their initial response before I noticed the cooling issue was "RMA It". But that doesn't work for me because I rely on this thing for my livelihood (to include rendering videos). I can't just send it off for a couple of weeks and wait for them to maybe fix or replace it a month or two later. I've asked them to help me troubleshoot the cooling issue and so far I haven't heard back.
I've never overclocked anything before so I don't have a lot of experience fighting with cooling issues. My last couple of builds have used Corsair liquid cooling solutions (H70 and H105 I think). This thing has a proprietary cooling loop - looks like about a 120 mm radiator. Again, it was just fine for a year, but something has apparently gone sideways.
I've enabled "Smart Fan Mode" in the BIOS for all case fans--not sure why it was off, but I guess because of noise--and now the fans spin up like mad when it heats up, but they're not getting the job done.
I did notice (and remove) a fair amount of dust built up on the front panel air filter, but cleaning that was unsurprisingly not the solution here.
I don't know what the normal RPM should be for the "pump fan" listed in the BIOS hardware monitoring, but I couldn't help noticing it seems to be running about 5x the RPMs of the other fans.
Any advice would be appreciated, thanks!
