Electrified backplate?

[tikker]

I have watercooled my 1080 Ti using the EK waterblock and backplate. When I touch it with my hand and move around I can feel this kind of ``vibrating'' feeling, which reminds me of the tingly feeling when touching something that has a slight electification to it. When I touch the case and feel the backplate this sensation isn't there. Could my backplate be electrified somehow? I don't have a multimeter to check it quickly so I thought I'd ask here first.

The vibration is probably caused by the fans or other components in the system. The voltages at which the system operates (12v DC via PCI-E) is not enough to shock you.

Hmm, yet I don't feel them when just touching the backplate and holding still. Only when moving my hand around and not touching the metal of the case.

That's just the material, it might create a teeny tiny amount of Static electricity, or it's just the feel of the material-

There are special suppression capacitors in AC-DC power supplies, that couple the mains AC side over to the DC side, this is done at 1/2 of the RMS voltage (for me it's 120v, for 120 volt mains it'd be 60v) however the backplate should be grounded, so unless you're touching +12v that won't happen, but there DC side is coupled over to the mains side. They're called X and Y class suppression capacitors, usually 1000 and 2000 volt rated.

Probably just static electricity then, if any at all. Or I'm going crazy  Guess it's all fine then.

Time to think of other things that can be a culprit for system instability...

Your finger is rapidly bouncing up and down as the friction stops it, whilst you continue to apply pressure. Your finger hops up a tiny bit, moves forwards, then gets 'stuck' again.

Probably, intersting coating on the backplate then. So smooth yet rough enough to do this.

Well, 'smooth' is just bumps close enough together that it feels like one, uniform surface.

True.

It's just my system has weird booting issues yet when I RMAed they found nothing, so I'm thinking of pretty much everything at this point...

Should lick it like a 9volt. Only way to know for sure.
