Replace Pumps on Radeon R9 295x2

[OldBigWoody]

I have 2 Radeon R9 295x2s that I have had for several years. On one of the cards, it seems the Asetek pumps have failed. No movement of liquid can be felt through the plumbing. Using MSI Afterburner, the temps slowly creep up to 78C under idle load and then computer powers off to protect hardware. The on board fan and the radiator fan work fine. I am interested in replacing or repairing the pumps. I have contacted Asetek about RMA and repair procedures but have not heard back yet. What options do I have to get these pumps up and running again? How do both pumps fail and not just one? Any insight would be greatly appreciated.

 

Computer specs:

 

GA-z270x-Gaming K7 motherboard

Intel I7-6700k CPU

Corsair H100i V2 CPU cooler

16GB of Giel 24000 RAM

2 R9 295x2 GPUs

EVGA supernova 1600W Gold PSU

5 SATA drives

1 M.2 SATA drive

The simplest way to go would be getting waterblocks for the the GPUs and running an open loop.

I did think about this and was planning on purchasing a waterblock but I hit a road block when I could not find one in stock. It seems those manufactures have moved on to more popular form factors... I appreciate the reply.

Does the rad get warm?  A cool rad and an overheating card is a sure sign the pumps aren't running.  If you can't find actual water blocks for your card, you could likely modify the existing pump/block combo to use them as a block.  Depending on how they come apart you might be able to just yank the impellers out of them, put them back together, and then use an external pump to shove water through the now-empty pump housings.

That is a good idea. I think this is going to be my last resort to get it up and running. I tried looking on the old ebay for water blocks but its barren. If anyone finds a waterblock let us all know!

Ended up purchasing a broken 295x2 on ebay and will replace pumps from that. Thanks for the input on this!
