Is there anything suspicious with those temperatures? (THERMTRIP on TR 5965WX, WRX80 Creator mobo)

Lapsio · April 23

I'm using Noctua NH-U14S TR4-SP3 to cool down Threadripper 5965WX (280w) and since I started loading this system to 100% of its capacity I noticed that I'm occasionally getting THERMTRIPs and whole machie shuts down. It's fairly dangerous in my case since this machiene has RAID array that could easily get damged from such dirty shutdowns. I'm not entirely sure where to start troubleshooting. According to my home temperature sensor, PC has intake temperature of 29.5°C which is maybe not perfect but shouldn't be terrible either. I don't have AC at home so it is what it is during summer. Here's how my temperatures look like according to IPMI on motherboard:

Threadripper has Tjunc of 95°C so it's very uncomfortable stable state. According to OS sensors reading it reaches even up to 94.8°C which is nearly trip threshold. However other temperatures in chassis... don't really look all that bad. I mean even if we take a look at DDR4_H which is bottom RAM slot on motherboard (place where cooler intake is located because NH-U14S TR4-SP3 is vertical flow configuration:

it's 43°C so ambient near CPU cooler intake can't be higher than that. Socket temperature also doesn't look too bad. All fans in chassis and on cooler are Noctua IndustrialPPC 3000 rpm jet engies so it blows quite hard. There are 4 intake fans, 3 exhaust and 2 on cooler. All of them are the same 3k rpm 140mm. Case inside looks like this:

Behind vertical GPU there are 2 more GPUs for CUDA and network cards. Total power draw of machine is around 1200-1300w on outlet power meter. Around 700w with CPU-only load and idling GPUs.
