    Posted: 14 Aug 2019 at 5:08am
Worried about my new upgrades. Running a 3700X, 16 GB 3600 MHZ CL18, GTX 980 Ti and the X570 Steel Legend. I've put the GPU in top slot as the computer won't post with it in the second(which is also only 4x). I have removed the shroud from the GPU so there are a few mm between the GPU and the chipset fan. It's in a well ventilated Corsair 600T with ample airflow and proper cable management.

My issue is in an about 24-25C room, writing this very post, the SB temp is hitting about 72C. Earlier today I did various stress tests(OCCT CPU and GPU) and got it up to around 85C. Playing Division 2, HWINFO reported it maxing at 86.8C.

This cannot be intentional? I saw a youtube video stating ASROCK says the thermal limit is 105C, can anyone confirm that?
Furthermore, the chipset headsink is hot to the touch. I worry that my M2 drive(Intel SSD 600p 1TB) will take damage as operating temperatures state 0-70C. I thinking to pull it out and use my PCIE extension card, though that seems pretty silly when you have M2 slot readily available.

Can I expect this to improve with future updates to BIOS/Chipset? Any tips on how to improve this? Should I just accept it as normal?

Have you checked what your chipset fan is set at?

My x570 Taichi chipset fans default setting is performance and it runs 4500rpm and the temp stays around 60c.. I'm using a Phanteks Enthoo Pro-m with two 140mm noctua fans at the front intake and another 140mm noctua exhaust and a 1080ti sitting right over the chipset fans intake.

I think Asrock should have thought about the chipset fan placement a little more..

It's also running performance. Just turning the computer on, the SB is about 60C, with the fan running at 2500rpm. When I'm hitting around 85, I think it was around 4500-4600rpm.

Updated to new BIOS 1.70. No change in anything. Just sitting in the BIOS, it creeps up to around 80C and stays there. The fan is running at 4200rpm. Removing the side panel doesn't do anything.

I think the motherboard is rated for up to 125C

I'm Running a 3700X, 16GB 3200MHz (OC to 3600MHz CL16), RTX 2070 in a Phanteks P400S case.
My X570 Steel Legend's SB maxes at 77C. But I don't use any M.2 drive, though. Just regular SATA SSD.

Which power option are you using? With Ryzen Balanced, if I just leave the computer idle, it will eventually creep up to around 75C. 90 minutes of rocket league, and it was at 88C.

What is weird though, is both my GPU and my M2 drive, should be directly wired to the CPU, as I'm using the top PCIe slot and the "hyper" M2 slot. So essentially only thing the Southbridge should be handling is 3 SATA drives and a few USB devices (mouse, keyboard, sound).

Do you have a source on 125C though? Because if it is that high, I'll just have to set a constant semi-high fan speed that doesn't whine, and then I can live with it.

I'm using the Ryzen Balanced Power Plan. It reached 77C when playing Anthem.
On light web browsing or watching 4K Youtube it's usually at around 65C and at low 60s when idle. I use a custom fan profile on the SB_FAN settings.

I forgot where i read about the 125C temp, maybe it's on r/AMD reddit.

If you touch chipset heatsink(the one covering the M2 slots), it is also pretty hot? As in, more than say 5-10 seconds and it starts hurting? Was wondering whether the heatsink on the chipset itself is incorrectly mounted... will check when I get home again.
