Is RX 9070 VRAM temperature regular value or hotspot?

AMD reference card 9070 XT change of pads. 10 April

https://wccftech.com/amd-radeon-rx-...eplacing-thermal-pads-fixes-high-gddr6-temps/

6c lower VRAM temps with changed thermal pads to T "grease"(I guess putty) in Furmark but, has Samsung memory and 8 heatpipes heatsink.

Also if you notice heatsink exhaust is not covered by the plastic shroud, similar to some 9070XT XFX and Gigabyte.



AMD reference card heatsink thickness and exhaust is let's say ideal(but is a smaller card and we have to consider that, I believe is 12cm width by 5 cm tall) and than we have Pure which cut off a hefty amount of heatsink thickness same as the most expensive card from Acer, Predator. Than we have the Acer Nitro which is funny, they remove the fins from the hottest part of the card to the tail. Why?

I guess Acer on the Nitro card they hopped the heat pipes will carry all the heat to the tail of the card where the third fan has a blow trough and is more efficient in cooling the whole card Meanwhile GPU, VRAM and VRM will not agree to that. Without high RPM that card I believe will run hot.


Above all is very strange that is very hard to find pictures of Nvidia or AMD cards from this angle(like u see the Pure card above or the AMD reference), showing to amount of shroud/heatsink coverage.
If heatsink is revealed in high % and has no aesthetics, yes, is no marketing in that, I know is ugly but is necessary. The more the exhaust is covered the more noisy card you'll have and more often you'll change TIM.

I might try those mods at some point in the future. I'd use putty instead of pads though. Good to see the RGB Devil blocking the fan grill can be removed. That should really open up airflow for the 3rd fan.

I haven't seen any real issues with temps yet, but I might see them in the future.

Is the €940 for the Red Devil or Red Devil Limited Edition? I paid $790 for my non-LE Red Devil. Prices have gotten out of hand, for sure.

Make sure when you add thermal putty or thermal pads on RD back plate you cover drv mosfets as well, there are 2 columns of drv mosfets on the left and right of the VRAM.
I added just the picture of the 2 easy to miss.
IMO no backplate thermal pads on such condensed PCB is a a big NO.

This review shows that in Steel Nomad test RD VRAM reached 92 C.
PCBs contains Copper layers, sometime ceramic layer too which will make heat transfer faster trough PCB.

Why bother removing the LED panel? Why not just buy a cheaper model that doesn't have it in the first place, like the Hellhound for for example?

While the weight and number of heat pipes offer a more silent and better cooling with RD card, I can easily take off the silly panel and add thermal putty for the back plate making it even more efficient and silent. I can not do that with HH card can I?

You ignore 3 more heat pipes and over + 300 gr heat sink but I can't. Why are you ignoring the differences when we actually talk about cooling? We have different mindsets, yes but try to be objective pls.

And whatever I do with HH in terms of added stuff, will be inferior to RD in terms of cooling not to say RD has a better voltage stability in the silent BIOS.

How does the Hellhound have 4 heatpipes when the Reaper has 5? Something's not right there.

The hunt for silence is a valid reason. I'm just wondering where the line of extreme costs and diminishing returns is.

...and he realize that they are cutting corners. Most of them does not only PC.
IKR Wizz counted 4 for the HH.
Let me show you how bad it is in the example bellow where they literally cutting corners and never the less 2 expensive cards. Asus TUF and PC Red Devil.



2 memory modules are half cooled from the back while another 2 only 70% cooled. Resulting in 4 modules/card not properly cooled.
Sapphire did it right in covering the entire chips but, they failed to cool the driver mosfets from the back.

However the point was that HH has 4 heat pipes while RD has 7 and over 300 gr heavier. So IMO is worth buying the RD, remove led panel and add thermal pads to link the back plate.

As for the second point.
Costs IMO will worth in the long run in stability of your card and longevity.
Fiddling with settings to stabilize a card with too hot drv mosfets and VRAM will be time consuming, IMO is not worth it.

Did you move your Reaper in another PC case?

I did, now I have 2x 12 cm fans blowing fresh air at it. It lowers idle temperatures nicely, but doesn't do much at load (-2 °C at most). So I'm concluding that the high VRAM temp is by design on these cards.

At least you tried, can we have a picture of your current setup?

Already wrote about that. I would go for Red Evil if it had backplate utilized properly.
PowerColor is cheaping out on GPUs. I remember when even budget-oriented Sapphire Pulse version had thermal pads and PowerColor's GPU's lacked them.
I mean no one cares about missing thermal pads (between PCB and backplate, ofc) on lower end models like RX 7600, RX 6600 etc.

Sure - it's on the last page of my build log, link in my signature.
