EK Water Blocks EK-Quantum Vector FE RTX 3090 - Dead GPU

[B0M8ER]

Hi All,
So I have just purchased this GPU water block from Overclockers to add to my CPU loop and I am having some strange issues.

Basically my card is dead while using this block, I have spent seven hours building and re-building to no avail, I have checked every screw and every thermal pad and every connection to the exact manual plan and also followed some YouTube videos to see if I have missed something.

As soon as I plug the card in to the motherboard on its own (just for boot) or re-build the original cooler back on the card, all works fine with no issues.

I would say I am very experienced as I have been building custom loops for over 15 years but this one has stumped me, I have contacted Overclockers for an RMA, do you guys think this is a manufacturing issue and the only resolution or is there something I'm missing with the 30 series cards when water-cooling?

Thanks, Martyn

Yeah, I have tried everything, It does it even with just the water block attached and no I/O plate or back plate...........That's just the four screws around the GPU die..

I was going to try washers on the standoffs but that would probably cause bad contact from Die to water block..

Is that with the washers?

Hi,
Yes......clear plastic washers were used

Does it boots or is dead straight away?
If boots, even for few seconds, then some protection is kicking in.
If not, somewhere a short may be happening.
With the waterblock installed, does the card connects all the way to the PCI slot?

Hi,
NO, no boot and PCI slot was fully in.
