Hello,
I have had my PC and GPU (Sc2 Hybrid 1080 Ti) for almost 3 years.
Yesterday almost as soon as i turned on my PC , i got a notification from CAM that was my gpu was overheating (90°C) . I tried rebooting to see if anything  changed but no luck.

So i decided to unplug the GPU , dust off and shake the radiator to maybe eliminate airbubbles, i also replaced the thermal paste ( I thought my warranty was already gone, but actually i still had  a few months left, and i broke a little part of the backplate cause a screw was stuck , so my warranty is void now :s , Still sent a message to evga support but they haven't replied yet.)


GPU is still overheating, when the PC starts, GPU temp rises from about 50°C to 90°C, in a few minutes while idle.
The radiator is cold to the touch and the gpu itself is hot, and i feel/hear nothing from the tubes, so it seems the pump died.

1) Could it be something else than the pump ?
 
2) Is there any way to fix the pump ? 
 
3) If the pump is perma dead, is there any way to buy a new one without buying a new gpu ?  ( i have looked it up but didn't see any sc2 hybrid kit)

4) I read a thread about converting an Sc2 hybrid to fully air cooled ,  
but i'am not sure how to do it, replace thermal paste and slap an air cooler on the chip i guess ? but what about the vrams since they were also cooled off by the water cooling?

I would remove/take apart the pump and see if there's something in the impeller housing or a sticking bearing preventing the impeller from spinning..Maybe there's a way to put a little oil in the bearing if it's sticking.
 
When you go to reassemble it, be sure to clean/lubricate any rubber O-rings to reduce the risk of them being cut/damaged upon reassembly.

Thanks for your suggestion.
but since they are hard to find and may not be compatible with my card, i'll try to find a solution with evga support first.

have to sit a home, confined , can't go outside except for groceries=> pump dies after nearly 3 years, what a bad timing.
