Question Touching wire turns on my case fans? Electrical shortage?

[AdamMack95]

My case fans haven't worked in 4+ years. I have a GTX 970, i7 4790k, 16gb DDR3 ram, and ASUS z97 AR. I don't game anymore, so while my case fans not spinning has been annoying, it's not been a big deal in the grand scheme of things because my temps never got high doing college work.

The thing is, they would occasionally work for short periods of time. When I say occasionally, I mean about once every couple of months the fans and RGB would fire up for 5-10 minutes, then shut off again.

I got a new monitor today, and while checking my fan connections to see if they were loose, realized that me touching the wire makes the fans and RGB fire back up.

Surely this is some sort of electrical issue or shortage? I replaced the PSU about 2 years ago thinking it would fix it, which it didn't. My PSU is a Corsair RM850x. My case fans are a mix of NZXT and Corsair 12v DC's.

Please...just watch this video so you can see what I mean.

Both brands of fans made during a decade or so ago were all trash.

You don't check connections while the system is powered up unless you'd like to be a conduit for the electricity, since electricity will take the path of least resistance.

I would remove them entirely from your system and look into PWM controlled fans, tethered to a PWM fan hub and call it a day. Also, you should consider dusting the entire system's innards. The issue you're seeing, can also lead to melted connectors or a fire.
