[Awful Hydro X Temps - 3080 Ti and 3900X]

3090s have memory chips on the back side of the PCB, so they need at least a solid heatsink of a backplate, and not the flimsy aesthetics one Corsair provides.

EK and other manufacturers even offer active backplates which are basically a watercooled backplate precisely to cool the GDDR6X.

On mine i had load temps of 92°C on the memory when aircooled (same style backplate as the XG7)

72°C watercooled only on the front side with an aluminium backplate

52°C with active backplate.

For the GPU temp, it doesn't make much difference, but for the memory, a decent backplate is a must for 3090s.

Hmm ok. I have the 3080Ti.  I know there is only half the memory than the 3090 but are there any parts on the back of the 3080Ti i should be worried about?  I took the thermal pads off the factory cooler back plate and put them in the same place on the Corsair one. Is that ok?

What do you use to see the temps on the memory chips?

Why is the XG7 bad for the 3090 but not the 3080?

Thanks both.  I have opened up the side of the case.  I was running it with the 2 fans at the top and 3 in the front as all intakes.  This is why the internal case temp was high. I have swapped the top fans around so they are exhaust. 

I also screwed down both the top plate on the GPU and the CPU block. I didnt do them all the way up as I didnt know how far I could go.  I bottomed out the screws on both and now im only touching 53deg on the GPU after gaming for a while.

I will still have a go at doing my own fan curve as well, so thanks Leekay07 for the screenshot.

I have just finished my loop with the Hydro X system. I have:

360mm + 240mm radiators

XG7 for my 3080 Ti Founders edition

XC7 for my 3900X

During gaming, my CPU is hitting 73 degrees and my GPU is at 83 degrees. The coolant is hitting 40 degrees. These are worse temps than when they were air cooled.

I have each radiator fan set to the Hydro X option, as well as the Pump on fan header 6 as the pump option.

Does anyone know what is going on? I have spent quite a bit of time and money on this and i have added almost 20 degrees onto my components rather than taking what i thought would be that much off.
