Risers 008s vs 009s


so i’m looking to upgrade my risers as I have 007s as I have had a few problems with my pc running for 8 -24 hours then it will just cut out and I have no idea why, it’s a 5 x 1080ti rig and I know it’s just the 1 card causing the problem but I have changed all of the cables and still after 8-24 I will get no display output and the cards will stop spinning so I have no idea why it’s doing this

I can see there are 008s and 009s on the market but the 009s doesn’t look as good as the 008s which would you recommend?
