I think SMBUSMASTER 1 is the correct sensor, but it strangely doesn't go above 60°C. I did manage to lower it though! The problem was the GPU.

Sapphire Pulse RX 5700XT by default has very passive fans profile, and runs quite hot on idle. Using radeon-profile I enabled better cooling fan curve, and chipset temperature went down! GPU is basically right in front of the flat heatsink on X570 Taichi, and when it's hot, it affects everything from the chipset to nvme drive that sit under that metal plate).

Actually I've seen chipset jump above 60°C now, so it's not capped. I suppose SMBUSMASTER 1 is OK then.

Hi Shmerl, I know its off topic but was just wondering if you are going to post some superposition benchmarks for the pulse 5700xt.

I can give it a try.

Thanks, I'm thinking of getting the none xt model later in the week, to give my rx 480 a break.

Looks like it's OpenGL only though, so I'd say not as useful these days. Downloading it now.

Cheers, will take a look later this evening. Heading out now.

Here is the result. I've never tested it before, so not sure how it compares to other cards:

Thanks Shmerl, the benchmarks thread in the forums here suggest 1080 extreme for comparison and no-one has entered an rx5700. I'm guessing with your rig you should get in the top ten. I am also curious how quiet you find the card and how significant the difference is between the dual bios settings.
I have been a big fan of the open source drivers and have had a great experience with several amd cards now. The pulse looks like the one to get, but it would just be nice to get an opinion from someone using the open source linux driver.
Thanks again.

The card is pretty quiet. But I also have a new case, and I suspect thick walls contribute to general noise dampening. It's surprisingly quiet overall, even on full load (more than my previous case). Though I also made sure to replace case fans with Noctua ones (200 mm), and to use rubber connectors on them instead of metal screws. It's supposed to lower noise as well.

One thing to note. The GPU basiclaly stops fans rotation when under low load, and runs at around 50-51°C. When under load, fans start rotation. 50°C is a bit high to my taste, but to lower it, I'd need to use radeon-profile for the custom fan curve.

It might be not so bad after all, since the only downside is that heat spreads to the metal heatsink on the motherboard, that covers X570 chipset and NVMe drive. So because of that, NVMe runs at around 45°C on idle. When I set custom fan curve for the GPU, NVMe drive temperature drops to 35°C or so. Probably not very critical difference though.

I haven't tested the second BIOS with that switch. I simply put it to more performant one.

Drivers wise, it's hard to say yet. The Witcher 3 in Wine+dxvk works well so far (I posted results in TW3 thread. So radv seems to work for it.

Something like The Bard's Tale IV for example hanged altogether. Possibly due to radeonsi for Navi still being rather fresh.

Thanks Shmerl, I appreciate the feedback.

@Shmerl

Finally got round to installing my x570t/3900x

This is what I've got up to now, Not sure if you've sussed yours since your last posts.

Not sure if the Water pump and south bridge fans are the right way round.

Yes, k10temp works fine now in 5.4-rc1+ for me. No need to patch it manually. Chipset temperature is SMBUSMASTER 1 for me.

Quoting: ShmerlYes, k10temp works fine now in 5.4-rc1+ for me. No need to patch it manually. Chipset temperature is SMBUSMASTER 1 for me.

Me too, Not sure why I didn't add that :dizzy: I used zenpower-git from the AUR to get K10temps

There's no data sheet for the NCT 6798 yet so no idea what to do the scaler at for the 12v rail ect

I think in7 is 3VSB, in8 is VBat and int 3 being 3VVC

To add I think SMBUSMASTER 0: is CPU temp too

Hi Shmerl, I found this thread while Googling about the same problem.

What sort of chipset temperatures were you able to achieve by adjust the fan curve? I'm also getting 59 to 60 C chipset temps at idle.

In the end, I stopped using custom profiles. And I set chipset fan mode to silent. It's runs at around 55-60°C on average load. When GPU blasts to 100%, it heats up the surrounding area, so it goes up to 75°C or even more sometimes.

Thanks.

How hot are these compared to "normal" chipset temps? This is my first time building a PC, so I have no point of comparison.

Do you worry at all about the temps wearing your motherboard out faster than normal?

I don't think it's a problem, unless it starts hitting something above 90°C or so. But you can contact Asrock to confirm it, I'd be interested in that too.
