Should I still worry about cable bend?

HungryHamster

I'm installing a RTX 4090 and there's only going to be 30mm of room between it and the case side panel. I have the CableMod cable and they recommend that the bend not get started before 35mm:

I know pretty much all the incidents of melted cables are due to user error with it not being fully inserted. If I make sure it's fully inserted, do you think I should still worry about having that cable bent up against the glass?

JTC explained about this, the reason why there's a rule for it is because the heat build up from the power current is worse when it is bent. So I would strictly follow the guidelines to avoid any issue.

Thanks for your response. I know the heat build up is worse, but I guess I'm wondering if that's a big deal. I saw some testing from GN and others that tried to get the cables to fail with just a significant bend and when they did thermal imaging on it, it only got up to around 50c while under full load. They never got it to fail that way. I would only start the bend 5mm less than recommended. I can't imagine a lot of people have a case that accommodates 35mm of room before any bend.

I guess at this point that would basically be your call. I would like to play it safe, but:

I have a Define 7 XL and I'm not confident it can fit a 4090.
