** R9 290X Watercooling Thread **

Some website seem to think the new drivers only improve the 290 and not the 290x, sure as it is the same GPU it should improve the X aswell :/

If not then the X doesnt look so great for price.
 
Don't wanna double post so I'll leave my findings here:

http://forums.overclockers.co.uk/showpost.php?p=25274613&postcount=1473

Running stuff in sig, cooling with:

1 x HWL Black Ice GTX 360
1 x EK 120
1 x EK 140

Scythe GT's @ 1450 ~ 1850RPM - cooling CPU/GPU/RAM

Not running a modded bios, gonna wait for an afterburner update, I get artifacts if I run Memory above 1450 currently, but deffo need more voltage to push my card further.

EK Block

I currently have my FX8350 @ 4.7Ghz and my R9 290 running @ 1150 core 1350 memory stock voltages. My single rad 240 loop keeps my GPU at a constant 49'C on BF4 running Ultra. Great compared to 95'C

Who needs screw holes when you have thermal adhesive? :D




I will say that getting that off is a fair bit more difficult than the little ones due to the shape though...

I would like to bump this to say I added a EK VGA universal waterblock, Alpenfohn heatsinks and the single large Alpenfohn VRM heatsink attached with thermal adhesive in the same way as Uncle Petey did above, and the results are pretty great. Core maxes out at 38c, VRM one hits 56 and VRM two 44.

It was a pain to install but I will always prefer universal blocks, I hope the current loop I have can last 6 or 7 years with a little tweaking (2 so far).

Cheers the the innovative ideas guys.

So I have a 290x under water. I have been overclocking it with CCC and managed to get to its limit on stock voltage. It was roughly 1150 and 1350 or so on mem.

I tested in Heaven and began to see artefacts and crashes at anything above.

So I dloaded Trixx and run it on top of CCC, everything works fine, any adjustments in Trixx then show up in GPUZ and CCC .

Trixx I wanted to use for voltage control. The setting is called VDDC offset and goes from 0 to 200. Is this because the voltage of the card is dynamic ??

Also how do i best work out what voltage i have increased it by and whats a safe voltage to go up to on these cards ?

My current settings are 1200 clock 1500 mem with 150 on vddc offset. It seems stable and gave me a heaven score of 1536 on a 8350 at 4.3.

Is that any good ???

Thanks for the help I have learnt a lot about clocking etc today and so any extra help understanding the changes ive made would be great

Cheers
 
My rig is a 3770k at 4.5ghz and 2 x 290x at 1100/1450

Max temps on gpus are 55c ingame.

And 48c when mining. But under voted at 800/1375

I run two 240mm rads, ones 30mm thick and second is 45mm thick.

with GO fans.

I never run them over 75% speed and it cools my system perfectly well

why not I wanna see pictures and your temp your getting. :)

VRm2:25

After Heaven (max C):
Core:64
VRM1:56
VRM2:47

after Heaven (settings in pic):


The guts :), bear in mind its not a very big case.

Well my vrm heatsink fell off at some point last night. Thank god for the cable-tie I put on just in-case as a 7950 sits just below it. VRMs went up to 95c.

Guys I've fitted my first ever full cover block to my 290 :D

Problem is temps, I'm using a Bitfenix Phenom case with a single 60mm thick Thermochil PA 120.2 and loop order is as follows:

Pump > Radiator > CPU Block > GPU Block > Reservoir > Pump

GPU maxes out at 50c after running Heaven 4.0 on loop, VRM temps are higher then expect though.

VRM1 - 65C
VRM2 - 43C

That's what they settle on, now I have the water flowing over the CPU and GPU core first before it flows over the VRM's so are the VRM's running at that temperature because the water is just heated up too much before it gets to the VRM's?

Also do you think it would be worth adding a 60mm thick 120mm radiator in-between the CPU and GPU block to help drop the temp that little bit more?
 
Water temps won't be the same as VRM or GPU temps and I don't think it makes much difference which way round the components are cooled. On my 290s they are cooled in series one after the other and the 4th card only runs about 1c hotter than the first.

Your temps look fine for a 290 on water, adding more rads will bring the temps down a bit but not a huge amount.

Cheers, they're not that expensive but I'm sure I have one laying in one of my draws.

Here is a loop of Heaven @4K I have just done to show the temps cards get to on water.

Much the same as your 290X
