How tight can I bend petg tubing?

[axlrose]

So I'm thinking of trying out my first water cooled setup and I want to try teaching myself to bend petg.

I'm thinking of putting a line between my reservoir and my cpu block that goes away from the motherboard and then makes the fallout lightening bolt image and then goes back toward my motherboard to connect to the cpu block. Not sure if I'm explaining that well enough, but basically I want the line between the reservoir and cpu block to be the fallout lightening image. I don't often see bends tighter than 90 so I'm wondering if that is a petg cardinal rule or anything.

Thanks for an insight.

Bends produce resistance to liquid flow but pressure rises so you are introducing more problems to cooling for questionable visual effects.
