It doesn't seem to be a problem to find the brackets if you do a little searching on it, but the problem is...
Can anyone tell me what the hight difference is from the die to the frame on the GPU? These cards need a shim or pad in between the GPU and the cooler head, and I don't know what the dimentions are for it.

And do people recommend Thermal Pads or Copper Shims and why?Tthanks beforehand smile.gif

Never heard of using a thermal pad on the gpu. Not sure if that would work out too great for you. I used http://www.frozencpu.com/products/14971/ex-blc-1051/EK-VGA_Supreme_HF_HD7970_Cu_Adapter.html
on both of my 7950's. Used the mkII from kepler dynamics for the bracket on one and just ended up using a seidon 120m cooler and some 3mmx25mm machine screws on the other gpu to attach it since the holes line up.

Well I took the leap a few days ago. Thermaltake Water Performer 2.0 and a Sapphire R9 290.
Now I'm here to troubleshoot a little.

My computer boots just fine, and seems to have to issue running idle, resting at temperatures around 40C - 50C. But under load it's unable to handle itself whatsoever. Playing a game will skyrocket it past 95C, and even a video will heat it to above 70C easily. But after the programs are shut down, it plummets right back down quite well, leading me to believe that the mod went off just fine, it just wasn't enough.

So, here are the potential problems I want to address here:

-I only had 16 copper ramsinks, which I used entirely on the vram surrounding the core. The VRMs still remain bare, and need to be entirely cooled by case fans.
-Water Performer 2.0 is getting a little outdated. Always a possibility that it simply won't be enough. If anyone has experience here with this model, please let me know.
-I had four fan cables that needed power, but only two outputs on the motherboard. The two radiator fans came with a Y-splitter cable, which took care of both of them. I had also used this configuration on this motherboard before without issue, so this was fine.

Next I had to attach the 4-pin cpu fan to the 3-pin case fan output, which should be backwards compatible, and seems fine, but this left the pump still to be attached. Some weeks prior I had ordered a molex - 3-pin adapter, but it still had not shipped, and would be at least another two weeks to receive it. So, the solution required a bit of creativity, ingenuity, and stupidity. I had a spare molex-sata adapter lying around unused, so I googled the pinouts, stripped the wires, and fitted it to the 3-pin cable. It didn't allow for any control or PWM, but it got it the 12v it needed, and seems to be running fine.

This all of course, led to the configuration being somewhat convoluted, and it may leave quite a bit of room for error somewhere inside. One obvious problem being that the radiator fans are now controlled by the CPU temperatures, rather than the GPU.


This leaves a number of problems that I have little way of testing on my own. I have tried using both speedfan and the BIOS fan controls to adjust the fan settings to match the GPU, but it has yet to have any success. Really any help would be appreciated, since I've been out of commission for near to a week now, and would hope for some returning functionality soon.

Your cooler isn't making good contact..Did you use a shim?
post #2054 of 3006
Thread Starter 
Im using the keplerdynamics bracket on my 2 7970s.
Didnt need to use a shim since both of them had the core protruding past the protector.
One stuck out more then the other.

Id recommend against trying to remove the protector. Gave a go at removing mine and wouldnt budge with a heat gun and razor blade.

A shim would be better, you need to apply thermal paste to both sides of the shim (touching GPU and touching the cooler).

But, it I were you, I would just remove that square and go no shim.

I just ordered this bracket -> http://keplerdynamics.com/sigmacool/radeonmkii and the bracket comes with a shim.

Thanks to both of you smile.gif

Actually found the EK-VGA Supreme Adapter last night and decided to just order it immidiatly smile.gif
And thanks about the heads up with the bracket... Had not noticed that one... Found a Pulse Modding Bracket, that looks pretty much identical to the one DWood used to make, though the one with room for a 92mm fan, has half of the 92mm bracket cut off, which I'm kind of scared of since I have a feeling that might cause some vibrations from the fan and make noise...
Really want a bracket with room for a fan to cool the VRAM, though I'm pretty sure I've read that the Sapphire cards have heatsinks on 'em... One can never be too cool or careful though tongue.gif

Any of you know of any other brackets with room for VRAM fan? Would be MUCH appreciated smile.gif

have any info on how to remove square shroud around GPU?
Last Mod I did I think the shim slid over and was touching the shroud which shorted out my GPU. (got RMA though)

I have seen it done in a video, but I do not remember where.

You don't need a bracket with w/ VRM fan, just get something like this http://www.ebay.com/itm/PCI-12cm-Dual-Fans-Mount-Rack-Cooling-Heatsink-Bracket-for-Graphics-video-card-/150964042576?pt=LH_DefaultDomain_0&hash=item2326287b50

2x 120s will cool down the whole PCB, presumably you have heatsinks.

I also ordered http://www.ebay.com/itm/100x110x25mm-Aluminum-Heat-Sink-for-Electronics-Computer-Electric-equipment-H152-/190709644522?ssPageName=ADME:L:OC:US:3160
to be used for VRM 1 and 2. Mind you, it will be quite a lot dremel work.

A couple of months ago I sold my 2nd 7970 and my full loop.  I forgot how insanely loud the reference cooler is on an OC'd 7970, so after a trip to Microcenter, and a little cutting and modding this is what I came up with.

 

Diamond 7970

Cooler Master Seidon 120M

 

Clocks:

Voltage: 1.24

Core: 1215

Memory: 1550 

 

Max Temps:

Core: 60

VRM1: 76

VRM2: 62

 

Looks like I need to do a bit of dusting in my case, but dusty fan and case aside, I am very happy with the results. :D

Getting one of these for my R9 290


should be pretty good, considering the radiator is really thick. Has anybody used one of these before?

No, but considering it's design was to keep the Overclocked 8350s (9xxx Series) CPU's cool, it should work nicely.
