I have two gigabyte 1080ti waterforce aourus extreme with built in waterbkock
I am using one ekwb extreme 240 for both of them for 3 years.
Last week my pump got stuck.I opened it and fixed it.
About 1 month ago till now one of my geraphic card after about 15-20 min under load gets 78C,but my another card is about 52-58C
Both of them was working about 46-49C
I read that my gigabyte 1080ti waterbkock cant be opend.
But I disassembled the whole loop and cleaned it as EK said
Whats is wrong with my loop?

Check your warranty, if it's no longer valid, go ahead and take the block apart, it's likely gunk build up.
 
Whats your flow rate on your pump? Does the speed gradually decrease?

Vital information as it will determine whether the blocks are blocked or not. Mine did this and the cpu block was absolutely hammered with gunk. The the flow rate would start high then drop until the fluid is barely moving.

I dont know how to find flow rate on my pump!
Please tell me how can See that?
But if fluid barley miving,how another geraphic card that connected to the same loop is 50C?!
In my mind,If fluid barley moving both of them should get high temp

It will speed up as it leaves the pump, hits first gpu and its fine then slows down as it hits second gpu thats possibly clogged hence your difference in temps.

By the sounds of it, both probably are clogged but one worse than the other. You'll need a flow meter to see your flow rates, a digital one is best so you can see an actual reading.

Is it possible that flow rate of pump decreased or pump cant do its job?
Maybe its some how got damaged because of clogged or ...
Last week that I cleaned it,it looks good but I am not sure that it works fine
Are you sure that problem is the block not the pump or radiator or the fans of radiator or ..?

If the second block is plugged it would affect flow uniformly through the loop and affect temperatures uniformly. If on the other hand part of the second block is plugged, that part of the chip would not be cooled properly. So, is there a potential blockage in the second block? Yes, there could be.

There also could be a different cause though. It could be that the overheating when the pump was not working has caused the thermal compound on the second block to dry out and it's no longer providing an effective heat bridge.

Is it possible that just one of thermal compound dry out and the other one nothing happens?
 
yes, it is. if one had a thinner spread it would have dried faster than one with a thicker spread.

unfortunately there is one other scenario which is that one of the cards was damaged when your pump failed and now doesn't control itself properly. I would really suggest dismantling both cards down to PCB, heat plate and cover. clean the pcb, inspect all the components looking at the caps in particular for any sign of a domed end. check the thermal tape and see if it needs replacing, new paste on the chips. clean out the heatplates with a toothbrush and some toothpaste (not joking). clean the inside of the covers the same way.

I will do that
Tnx☺️
 
I really dont know what to title this...
You can not take it apart with out destroying it.
The face plate cover, and the top cover at the ports are glued on. How do I get this thing apart for cleaning?


When I called Gigabyte,
ME: How do I clean this card?
Gigabyte:" we do not recommend cleaning them."
ME: Do I just put it back and let it break, then send it back?
Gigabyte: " we dont recommend that either. "


In these two topics you can see no one gets a correct answer:

Please help meeee

It my not help but try backflushing the blocks with soapy water. Take the cards and pump out, put the input to the pump into a bucket of warm soapy water, connect the pump outlet the the waterblock OUT port, put the out port Into a drain or back into the bucket. Turn the pump on and let it run. Do the cards one at a time.

Thoroughly flush the blocks with clean water before re-installing to remove any soap.

Doesnt it hurt the pump?
Or dirts get stuck in pump?

Any other idea please?
 
Buy a set of triangle security screw bits and take it apart?
i second this. they use a standard Chinese size screw that is not a common size over here. The triangle screw driver should work and be easy to find. You could also use a torx screw driver (be careful in case of stripping the head.)
