Watercooled GPU but HOT backplate

[newtekie1]

Air temp inside the case, temperature in the room, water temp...

Man, take a physics class. The backplate being hot is not going to affect the temperature in your room, or the water temp. Well, actually it will, but it will make the water temp lower since the heat the backplate is dissipating won't be going into the fluid, so the fluid will actually be slightly cooler.

I'd bet the zotac block doesn't touch the Memory VRM as well

Actually, it does.

What it comes down to at the end of the day is your unrealistic expectations on what a waterblock should be doing. It does not cool every hot component of the card. It doesn't matter what waterblock you put on a 1080Ti, or any graphics card, the backplate will heat up because all the components on the PCB are producing heat, and the backplate is going to absorb that heat.

Well... I just learned that the ek water block for the aorus xtreme edition 1080 ti DOES NOT cover the memory VRM section...!?!

What the hell were ek thinking lol

Here's the block I should have bought instead... Man the obstacle just never stop adding up when doing pc watercooling lol

You're over estimating things. That memory vrm puts out negligible heat, estimates put it around 1-3 watt. The stock cooler doesn't even really cool it much. Take a look, its covered by 1/4 in thick thermal pad that's basically useless. If EK didn't deem it needing to be actively cooled they probably know what they are doing.

I actually would be happy if the back plate is doing it's job which is to support the card and get hot, it's another heat spreader, so it's dispersing the heat correctly. I'd be more concerned if it was cool to the touch under load, course he could always add a fan to the back of it or go refrigeration cooling or just step down to a 1060/1050Ti.

I think worrying is like rocking a chair, it's something to do but gets you no where.
