Thanks Jedi @LtMatt hope you can help or share experience with the below, and thanks for your time Sir >

Dear Members, was hoping you can help or advise

-I recently purchased and installed a Sapphire 6900xt Toxic limited edition AIO card - great performance but way too loud - Latest AMD drivers set to automatic and default, tried profiles, rage and quiet no difference.
-I can start any game fresh and they start ramping up very quickly to 100%.
-The clocks are amazing as it hits 2500+ sometimes and is stable but man just too noisy (made sure case fans are not the problem).

My experience with any of the recent cards is that the fans are pretty quiet now a days until of course I got this AIO one?

I am very technical so please advise in depth if necessary - much appreciate your help...

Yes, one very happy and very fast Toxic owner here. :D

The stock BIOS on the card is the performance BIOS. The downside of this is that it will not let you reduce the fan speed below 38% and the stock fan profile on the performance BIOS is aggressive.

As you have found out, it gets loud at high speeds. Luckily, you don't need to run it at full speeds or anywhere near.

Look at the side of the GPU and flick the BIOS switch to the middle BIOS option. This is the quiet BIOS, and will let you reduce the fan speed to silent levels.

I find a fan speed of 34% is silent. I use up to around 37-39% when overclocking. You can go as low as 25%.

As mentioned by Jedi, have the rad sitting in the roof as exhaust. Feed plenty of cool air in through the front/bottom of your chassis.

When using the quiet BIOS, the power limit is reduced to 284W at default. If you increase this to +15% using the power limit found in Radeon Software > GPU Tuning, it will go up to 327W.

This is still lower than the performance BIOS, but should be enough for stock operation.

If you use MowerPowerTool (MPT) then you can truly unlock the maximum performance of the card for agressive overclocks and 2700Mhz+ clock speeds on the core.

Other than power limits and fan speeds, there is no difference between the two BIOS, so you can just use the quiet BIOS and then fully control fan speeds. You can increase power limits to unlock extra performance with MPT.

Hi Jedi, all great questions, yes at the top (under the radiator the fans are of the Toxic) pulling upwards

- Lian Li Mini new model case with EK AIO Elite x4 push/pull 140 side fans (outwards) on radiator
- x3 120 EK fans bottom (intake) upwards and
- x1 120 on the rear outward.


There is something I am suspicious of but not too sure at the moment...

Okay, sounds good.
 
That is amazing guys, thank you Matt - I new i came to the right place - was worried because suspicions about tampering with the card being 2nd user eBay - but got at a good price.

Just to add I set manual 50% fans and they were pretty acceptable and clocks still hit over 2500+ - but was worried when it gets hot if 50% will keep it safe -

final Qs
> using AMD driver built in manual fan setting, if I set it slightly below 50% so the noise is a little less then it is now, do the fans still ramp up (even if manual setting) if things get dangerously hot...
> If I need to change colour do I have to use that dodgy Trixx software (am scared of it because I had bad experience in the past where it messed up the fan speeds too in a similar way this card is behaving but on a Vega 64)

I am extremely grateful for the reply and help - will be in touch if any further interesting observations occur...

Junction temperature below 110c for Toxic Limited Edition (XTX) is safe. If you are using the Toxic Extreme (XTXH) max junction temp is 95c.

If you hit those temps, clocks and voltage will drop to try and reduce temp.

Trixxx software is fine, but it's only useful for changing RGB of the GPU, using Trixxx Boost (resolution scaling) or checking fan health. I have it installed but don't use it much.

You can customise the fan speeds to your desire in GPU Tuning. We wrote a knowledge base article here on how to tune GPU performance using Radeon Software. Customize GPU Performance Tuning with AMD Radeon™ Software | AMD
 
for those with a xfx 6900xt Limited edition (with the xtxh core), did xfx ever release a bios update or anything to change the thermal limit of the hotspot/edge?

also, any user feedback with the asrock oc formula?

No, the hotspot is supposed to be 95c. It's the same for all XTXH models, except for some reason, the Red Devil Ultimate (air cooled) XTXH.

I presume the Liquid cooled Red Devil Ultimate also has 110c max hotspot limit.

if that's the case, can they still overclock well? I was looking up the xfx's lower limit temps on reddit and that led me to your posts here. Yes i read the part where you returned it.

I am also looking at the asrock oc formula, the xfx limited edition. PC ultimate is too expensive.

also, by "Liquid cooled Red Devil Ultimate" you mean liquid devil ultimate?

Just a heads up @Too Tall , if you are using anything other than air cooling or water cooling (ie, Dice, phase, LN2, ice chiller, ect). Post your result as such so that it goes in the Extreme Cooling scores and not in the normal scores.

Nothing that fancy i'm afraid, just an ice room fan.

Mrs wont let me get away with an aircon.

Tootall is on regular water cooling, but if that's the case then the best 3090 score on Timespy thread should be in the extreme cooling section.
