AMD Radeon RX 6900 XTX Engineering Sample Pictured

[64K]

Nah, that still belongs to the furnace that was the 295x2, which peaked at 525W power draw all through a 120mm rad.

The RX 295X2 that I have seen had a fan and the 120mm rad. The one that Wizzard reviewed here ran it all the way up to 646 watts running Furmark. It only had two 8 pin. Including the PCIe slot power that would put it at 375 watts to be in spec.

Well sure the exaust was hot, but what about the GPU's themselves. IIRC the 295x2 ran in the 60-70C range for both chips under duress.

It might had different result if it was in well controlled room temperature, sadly I can't provide it. Apart from that, I'm also had hard time finding good position, whether positive pressure or negative pressure in closed chassis, both of which still make card hot unless I opened side panel. I think best single rad 120mm implementation is on the Vega 64 LC, but that's because GPU itself support undervolt.

my fury X runs cool

Because you just playing solitaire
Have you ordered the RX 6900 XT, mod?

 

[Gmr_Chick]

I'd say no, I had previous R9 295X2 and R9 FuryX, both has the same 120mm radiator and also both spewing dragon breath.

That Spartacus remake was really weird.

As was said above, a 120mm rad on a power hungry card, like the R9 295X2 and R9 FuryX, didn't bode well

Then go and learn some thermodynamics. When the water hits 55°C in that AIO, the radiator is virtually becoming a 360 with 35°C water and 25°C ambient.

The problem with single loop custom water is that the CPU and tha GPU differs so much thermally that the limitations of the CPU makes GPU-cooling imbalanced. Because of that you need to bruteforce it with 3 tines bigger radiators.

And you have no idea why having water temp of 55C is a bad idea do you?
Small hint: Water permeation and pump failure, basically the AIO would die pretty quick under high water temp for extended period of time. Fury X have high rate of pump failure I think

Just googling Fury X pump problem and there are so many links about pump whine and failure...
Even D5 and DDC pumps would have a hard time surviving 50-60C water temp for a long time, not to mention these tiny AIO pump

Every aio dies before the rest of the card its on. I dont see how its an advantage or unique selling point in any possible way. Its only there because air is not feasible. Nuff said...

If they start slapping subpar AIOs on every high TDP GPU, I'm glad I decided to stick with lower TDP, traditionally air cooled GPUs. At least heatpipes don't die on me (well they can but extremely rare).

Back from the University of Thermodynamics. This still seems like a bad idea.

One of mother's?

In past, the Fury X was considered "hot" because its operating temperature around 80°C, at least in my unit. When compared to competitors like the 980 / 980Ti, it certainly looks bad especially the latter only equipped with regular fan. Now standard has changed, I don't worry anymore with 950mV undelvolt 1950Mhz clock 1300rpm fan hovering in 90°C range

 

[Flyordie]

Uhh.. Isn't this the reason V64 LC has a reserve tank and a small port for refilling on the backside of the reservoir?

Come'on, i never had a AIO fail on me, ever. If the build quality is good then it lasts years.

That's from Gladiator 2, Russel Crowe is making himself a steak.

 

[ADB1979]

I thought that the XTXH GPU's were actually a newer stepping/revision rather than simply being the "golden samples" as they have an updated part number on the die itself

 

[DeathtoGnomes]

What no leaks about mining performance ?

a "regular" (nothing special, medium quality) 120 rad cool well 150 W. In other words 1W/sqcm

 

[phanbuey]

that's if you want to keep the coolant at a certain temp.

A 120mm rad CAN cool 300-400W, but the fan(s) will be going at 2000+ rpm and the coolant temp will be in the 50-60C range, plus the air coming out of it could be used to make beef jerky. The GPU will still be pretty cool, just due to the way they dump heat (and it's still probably better than the stock heatsink anyway) but I hope the el cheapo tubes, plastic/rubber gaskets, and the coolant itself is fine to be braising at that temp over time without breaking down.

+1 I always try to split loops because of this, but you do want to keep your fluid temps at around 40C if possible on a gpu loop....

These aren't exactly automotive grade parts, and some weird and not so great stuff starts happing as you get to 60C on the coolant.

 

[flatty]

A 120mm rad CAN cool 300-400W,..

Agree, I said "well" (decent temps, fans not becoming "helicopters, etc
I remember that exist an 120 rad (thermalright IF im not wrong) that was able to hit more than 550 W at 30 mm thick

If the build quality is good then it lasts years.

That is twice over, exactly the point.

- OEM build quality is hit/miss. There are many problematic designs, even down to simple things like choice of materials, tubing, etc. And let's not begin about pump failure. Corners always get cut.
- More moving and individual parts than air cooling result in a simple fact: AIOs break faster and are much more prone to it. Even with a decent design. If you think otherwise, you're lacking objectivity.

- 'It lasts years'... exactly, number undefined. And when it dies, your hardware is likely still going or capable of doing so. Its a simple fact they die or get worse over time as gunk builds up slowly and motors go weaker. A heatsink and a fan lasts literally forever, and worst case you'll replace a 5-15 dollar fan over its lifetime, or two over your personal lifetime if you really grow attached to it
