First build, Gpu hot hot hot.

Doing my first water cooling build. Thought I had it working perfectly. But when may graphics card gets any load the temp shoots way up to 90 degrees instantly from a 35ish idle. My CPU which is in the same loop with max load is around 50 degrees while being over clocked considerably so I think the water flow must be fine.

The build.
Ek pump\res 140 revo d5 combo
Ek coolstream xe 360 rad with 3x furious vadar fans
EK-Supremacy EVO Elite Edition - Intel 2011
EK 980ti water block

Water flows in that order.

In my noobish opinion, I think I've either messed up the thermal paste on the GPU or installed the block wrong somehow. Before I drain my loop and start taking my card apart I thought I'd ask if you non noob watercooling people agree with my guess off the problem. Any advice appreciated.

What are your CPU temps like?

I'd most likely say you didn't apply the thermal paste properly. Even an idle of 35c seems too high to me. Mine idles at about 20-23c at the moment.

May be a blockage in the block itself, pump might not being creating enough flow to keep the fluid cool. May be a massive air lock stopping fluid flow. I'd strip, reapply paste, check the blocks, make sure everything is clean and tight, fill her on up and make sure you've got all the bubbles out

I'd drain the loop,

If its instant or seconds from 30-90 then yes its likely the thermal paste or the block itself isn't making correct contact with the die.

But it could also be if the block is completely dry. Which could happen if it is setup wrong.

A couple of pics would let us see anything immediately wrong with the setup

instant from 30 to 90 isnt thermal paste (unless you applied like a spoonfull of it). Its most likely the block not making full contact with the gpu die.

Just updating this. Drained the loop, took the block off and reapplied thermal paste. Temperatures are now great. So it probably was either attached incorrectly or the paste wasn't right. Thanks for the help everyone. Now to see how far I can push the clocks.
