Air trapped in Waterblock? (EK Quantum Vector 3090 FE)

[Larry4D]

Hey guys, I have just a quick question. 

 

I've just installed 2x EK Quantum Vector 3090 FE waterblocks, and the bottom one of the two appears to have what I assume are bubbles trapped between the acrylic and the plate. Here's a photo of what I've spotted.

 

 

Is this normal/okay? I know there's been a few bubbles in the system and that they will take a few days to clear out, I just wanted to make sure there's not a fault with the block.

 

Also, here's a couple shots of the whole setup for bants:

 

 

Please excuse the mix of tubing - long story short I had the wrong fittings but basically this weekend I will be replacing all the clear tubing with ZMT (and redoing some different run paths, I can already pick out some better routes).

 

Here's a shot of it before the water cooling (temps were not viable...)

 

 

So far the temps (in the water cooling) have the vram temps at about 74c (down from 106 in aircooled) and the GPU die sits around 62c under a rendering load. CPU sits around 60-70C when rendering (5900x).

 

This is my first ever custom loop and will be an ongoing project. Machine is used for rendering with Octane and Redshift hence the GPU horsepower.
