AMD Radeon R9 295X2 Owners Thread

Hey guys I'm just after some advice on a fan setup for my 295, I've bought 2 Noctua 3000rpm fans and a splitter which will let me plug both of them into the header the stock fan usually plugs into.
However when I do this the fans seem to speed up and slow down constantly and never stay at a set speed, I was thinking it may be because they are 3000rpm fans and not the same speed as the stock fan.
Could someone shed some light on this and maybe tell me a good way to setup these fans?

Thanks guys :D

I assume they speed up when the GPU(s) are actually in use? The speed of the fan is controlled by the temperature of the water to my understanding when connected to the card. If you want static speed or to control your own fan curve, you need to put the header onto your mobo and control it like that.

If you go back a little, this is discussed at length in this thread :)

The fan header is not powerful enough on the R9 295x2 to control the 3,000 RPM Industrials. If you wish to have it controlled via the 295x2 you will need a couple of these. These are the strongest fans requiring the least power that will work with the header.

If i was you I'd use a fan controller to operate the Industrials and use those as they are beastly fans. I used four with my QuadFire 295x2 set up.
 
Ok thanks guys, right now I have them plugged into the motherboard (Gigabyte) and I'm using Gigabyte SIV to control them manually,
the only reason I wanted to have them auto was because sometimes I'd set them to say, 1000rpm manually, and I'd get an error and they'd shoot up to max speed and I cant change it till I restart the PC.

Really weird but ill setup a fan curve tonight using SIV and see what happens.

I got the best results performance/noise with 2 Akasa Apaches working at 100% speed. Dead quiet and work well even with overclocks under full load.

I assume you didn't try to flash the card yes?

The card is stock, never touched it.

Still no fans in afterburner 0% on speed and 0 on RPM.
I can see the fan on GPU-Z however.
That doesn't change the fact that it does the same thing all the time so I tun on the pc my room is cold and even when I am at login screen where you put password in like a minute it starts to spin faster.
This is the fan on the card itself not the rad. Card is on 34 degrees atm.
 
I have installed battlefront beta and now got horrible flickering in the menu...I will post video shortly

I really thing there is something wrong with the card and the warranty ends 27th this month...anyone got some tests I can do ?

If you go back in the thread you wil find some images where I suggest running OCCT. That usually shows up any errors for me. When I was having issues in the past with my 7970 I later run OCCT to find many GPU errors and to fix it I had to back down on GPU core clock quite a bit.
 
This is what's happening
I really need to narrow down if the card is faulty,
I will run the OCCT tomorrow for half of the day is that a reliable indicator ?
Can my increased speed on the fan from boot be an indication thats something is wrong ?

Create a new profile for battlefront and set crossfire to disabled, might work as that looks like a crossfire bug.

I wonder if anyone can answer my fan related problem tho...

I'm not sure what your fan problem is but I can relate how I works here ... for me, at boot, it'll go to 100% and it'll stay at that until the drivers have initialised and take over fan control (which is also roughly when the Windows login screen shows). And I believe every graphics card will act like that.

Thanks for this, however the increase of the speed happens after the 100% then the slow down and then it goes up again without any reason.

I had the same problem, fixed it by connecting the fan to the motherboard.

Hmm this might be the option but this was never happening before and rather then quick fix I would like to know if i can find the problem and if not RMA the card..

New discovery when the pc boots in the led on the fan flashes and when it again increases the speed after the windows start the led on the fan flashes few more times....
 
What's everyones temps like with this? 100% usage in BF4 it's sat at 70-71C with the windows open... I have my heatsink and fan outside the case as well.

That's what it ought to be ... throttles when it hits 74C (I have to underclock mine a little to prevent that, still intending to replace the fan).
