void the waranty is fun job
remove 4 screws

remove the four screws of the spring holding the cooler on the die,

They have used one way slotted screws to hold the cover on top of the pump and some triangle shaped ones .The security screws on the bottom plate of the R9 Fury X consist of four one way slotted screws and a few 1.5 mm triangle shaped ones

So here is what’s inside as can you see they have soldered the PCB with the electronics directly onto the motor. The labels indicate a I²C communication to the main PCB and also some alert output for whatever purpose, what you don’t see yet is the flex electronics which goes down to the copper cooling plate – I suspect some sort of additional temperature sensor, and I have no idea why they would bother doing that – except maybe the temperature everyone is reading isn’t actually the core but only the copper plate, that would make the temperatures look much better than they are.R9 Fury X –

below the cover is a simple white pcb soldered to the motor

Next up is of course getting out those triangle screws to see what the cooler looks from the inside. But wait, there is still water in the system. So first I have to get that out – trying to remove a tube without destroying it proved to be a fruitless effort, so I cut one near the radiator. A neon colored liquid came out of it – surely no simple water. Actually if you do some research, the R9 Fury X user guide from AMD suggests that it is some sort of „a mixture of monoethylene glycol / ethanediol“. Well I won’t drink it and you also shouldn’t get it on your hands either. A note maybe, the bowl I used is a very old one has chipped off at some places, the liquid is (as it should be) clear and nice.

Okay now with a 1.5mm triangle bit and a lot of pressure (yet again) I was able to remove all of the screws (I felt a bit proud). Out comes this:The cooling plate of the R9 Fury X with very thin fins

The bottom side of the pump used on the R9 Fury X.. left in all the sealing rubbers. One is as expected a square one around the whole block. The other one covers the top of the fins, so that the water has to go through the fins and can’t take the easy way out. The slot in the middle is where the water is pressed in and the small rectangle at the bottom is where the water leaves the pump block. You can also see the flex PCB, which I suspect to be a temperature sensor. I haven’t found any way to open up the block any further – I have no idea what they have done, maybe it is welded together. To complete the tear down I tried to get the PCB off of the top side. This turned out to be a bad idea (I think). After using a hot air gun and some force with the screw driver the PCB came off – in a bad way. Seems like the motor got so hot that in the end I pulled the contacts out of the motor and not out of the PCB.

The motor below the top PCB.. So what’s there to see? , the winding is loosely put into a hole which is then filled with some sort of glueish stuff to hold the winding in place. Failing to do so reliably which is also a cause for the noise and whining people are hearing from their pumps. Anyways I probably just have killed my pump.

What’s the PCB looking like? Not much to see on the bottom. You can see the pins I pulled from the motor, and the mounting of the flex PCB – there is also an IC under that black blob where the flex PCB is mounted.
Yeah and that is that. No way to remove the impeller from the pump, well I didn’t want to go to the extreme level and drill out the motor as I want to have it sealed. My suggestion for anyone trying to get the stock cooler integrated into a custom loop is to use the pump of the Fury as pump for the loop.
[attachmentid=4642118]
fit new tubes to the cooler .Standard 8/10 mm tubes will fit just on the stock tube mounts, use some tube mounting things of which I don’t even remotely know how they are called in English and you are done. It is sealed tight and no water came out.
The temp sensor most likely to measure water temp for how fast the fan on the radiator should spin. The core temp reading using software like GPU-Z/HWiNFO/etc pretty much the core temp.

, but the shader count boggles my mind not sure my card is a pure r9 290x or just an unlocked 290x anyway i can check it?
