Interferance from pump motor?

Sorry for the noob question:

Just wondering... all the parts of the watercooling set-up I'm planning have started to arrive and I'm laying everything out to decide where everything should go. Had a question as I was visualizing everything together:

The case is a Lian-Li PC-7x and I was considering putting a Danger Den/Laing pump in the HDD cage but then I started wondering... I imagine the motor on the pump is not shielded (I see no UL or FCC interferance notice) and I was concerned about what kind of problems that might create if mounted so close to the HDD which will also occupy that space.

Yeah, yeah, I know, there's motors in the HDDs that don't create any kind of problem and many people have fans mounted in close proximity to HDDs but I just wanted to be sure I wasn't missing anything.

Has anyone ever heard of any problems with pump motor interferance?

Also, as a side note... looking at the rear of the pump there appears to be a small header or jumper, like the headers on the motherboard for the Power/HDD activity LEDs, what is that for? Is that actually a LED header to alert for pump failure? I was going to jab an LED onto it but didn't want to go shorting out a $70 pump out of curiosity.

Thanks much,

BellaCroix
 
It would take much much bigger magnets and much more EMI to bother your drives.

The jump on the back of the pump is for improved starting at low voltages. If you aren't running your pump at under 7 volts, it's irrelevant.
