Thanks pauly, but my sleeving on this cables were really poor, I tried to get one piece of 4mm sleeving over the cables, but it just wouldn't expand enough, so I had to use a piece of 10mm sleeving on the thicker section, but at the end of the day, these wires won't be seen anyway, as they will be going under my rad in the basement of my TJ07 and then connecting to my fan controller.
I'm going to be fitting some grills onto those rad fans as well, hopefully I will be starting to move all my hardware from my current case this weekend, I am just waiting on my Silverstone CFP51 HDD bay thingy to get delivered then I can get cracking with my build..
@twist3d, if it is just the PWM signal that is coming from the fan header then I am sure you will be safe enough, can I ask how you go about doing this??
