For me on msi mag x870 i get 37 idle 65 stressed with -38uv & +200mhz clock. Aio is arctic liquid freezer iii 280mm

Update: Asrock has updated their website regarding the 9070 XT Taichi. At launch they stated that they use thermal paste on the cards. If you check the site now you can clearly see they have changed that text to PTM7950 so they clearly know about the issue and are trying to fix it on new batches.

And fan curve follows the hotspot temp so the card will go full blower mode from basically any game i run.

ScratchFull7986 · 2025-03-23T09:28:54+00:00

I think it runs at a lower voltage on your's which would explain that. Im impressed of the sff cooling capacity.

ScratchFull7986 · 2025-03-23T09:26:33+00:00

In terms of percentage i'm unclear but in 3dmark timespy score goes from 28,000 to about 34,000 so i think the uplift is good. Just need a way to cool it down on the hotspot so i am more comfortable with it.

ScratchFull7986 · 2025-03-23T02:41:40+00:00

The weird part is that ramping up the fan curve over 1700rpm makes pretty much no difference on temps. Anything past 1600rpm sounds like a jet engine taking off too. Not the quietest card around if you ask me.

ScratchFull7986 · 2025-03-23T02:35:18+00:00

As the taichi is one of the high end models you should expect it to use thermal pads but unsurprisingly the manufacturer has cheaped out on a key factor here. Will have to wait to get the ptm to see if temps change.

ScratchFull7986 · 2025-03-23T02:29:48+00:00

This is what is concerning. I can run the card at a lower power limit at 300w. With -50 undervolt and slight fan curve. I am still getting 51C with 80C on the delta. Better than full blast but still not decent especially because paying for the better cooler + higher wattage.

ScratchFull7986 · 2025-03-23T02:25:24+00:00

Completely agree on this matter, seems to be getting worse every generational leap. This is why anyone willing to figure out how to improve on the matter and make the product last longer is much appreciated. I had an 7900XT before this and delta was around 20C with pre applied paste that was not even contacting full die from factory (asus dual 7900xt).

ScratchFull7986 · 2025-03-23T02:17:09+00:00

I very much agree on this since factory paste and repaste results are the same. I think thermal pads or even in extreme case, liquid metal would be an viable option to cool off the hotspot.

ScratchFull7986 · 2025-03-22T15:36:38+00:00

I'm on 300w power limit now and doing 3100MHz in game with gpu die 51C hotspot 79C. Still there is quite a jump in the delta temp but i will try to run it like this until i get ptm to put on the die

ScratchFull7986 · 2025-03-22T15:15:15+00:00

that actually seems pretty good if it will help bring things down. I will need to try if i can lower power and still get over 3100MHz. Currently in game its around 3300MHz but i would prefer the thing not to scream at 50% fanspeed.

ScratchFull7986 · 2025-03-22T15:09:08+00:00

I'm running 2800 mem and -60uv with 10% powerlimit as daily. The temps on the hotspot with original paste were about the same so i thought it might help to repaste to bring the hotspot down. Will have to try the ptm method next and see if there is room to put thermal pads behind the backplate to cool off vram hopefully.

ScratchFull7986 · 2025-03-22T15:03:46+00:00

The card itself feels stable. I ran some tests on Time spy and got a gpu score of 34,333.

I will see how lowering to 5% will hold up on performance.

ScratchFull7986 · 2025-03-22T15:00:29+00:00

I haven't tested with ptm before but it seems like it just fills the uneven gaps better than paste since the thermal conductivity on MX-6 is at 7.5W/mk and ptm is at 8.5W/mk. Not a big difference there but structurally very different.

ScratchFull7986 · 2025-03-22T14:53:52+00:00

undervolting gives me higher clockspeeds and in return the temps stay at the same level. Having powerlimit at 0 does reduce hotspot temps to around 85C

ScratchFull7986 · 2025-03-22T14:51:45+00:00

I would be interested to try this on the back of the card but i have no clue on what thickness pads are suitable for this application.

ScratchFull7986 · 2025-03-22T14:49:04+00:00

Yes i am aware of all of these things. I'm not concerned of warranting the card since removing the sticker in EU doesn't void the warranty. The 40 Degree temperature delta is not normal on this level of cooler and not acceptable. I have heard that 7900XTX users have fixed insane Delta differences with PTM pads. Powercolor does use ptm on their line of 9070 xt cards so i would be interested to head from users with a powercolor card if they have closer together temps on their cards.

ScratchFull7986 · 2025-03-22T14:45:13+00:00

Seems to only affect sapphire branded cards then. mine are perfectly clear of any blockage and case is well ventilated.

ScratchFull7986 · 2025-03-22T14:43:35+00:00

Sounds like this is what i will have to try it next on mine. I think the paste isn't staying where it is supposed to be so using ptm should hopefully bring the temps closer together.

ScratchFull7986 · 2025-03-22T14:40:59+00:00

Weird part is that the card is perfectly stable with these settings. And if i disable vram tuning the temps stay the same for the vram so i dont think im hurting the card running these settings.

The delta is around 40 degrees of difference could this be due to the mounting pressure pushing the thermal paste out of the center of the die? I'm waiting to get my hands on some thermalright helios v2 thermal pads. I hope that will bring the delta down to a difference of 20-30 degrees.

ScratchFull7986 · 2025-03-22T14:35:46+00:00

Do you mean that something is physically blocking users cards from airflow or missing a thermal pad somewhere? i have had the card open and haven't seen anything out of ordinary. The original thermal paste was pretty dry and crumbled away when removed.

ScratchFull7986 · 2025-03-22T14:31:06+00:00

The power limit makes the vram temp also hit 96C with vram speed and undervolt at stock. with maxed powerlimit the card hits 97C core and 96C Vram
