Pump near gpu & mobo- an issue?

post #1 of 7
Thread Starter 
Talking with my dad and showing him my computer build thus far and how im mounting the pump and reservoir, he brought up something.

Him being an electrical engineer, he explained that the pump has a motor and any motor creates electrical noise and generates some sort of magnetic field. He went on to say by having the pump so close to the motherboard and possibly the gpu it can cause faults and possibly distort video due to the magnetic field/noise interacting with the traces on the pcb.
Brushless motors will create less noise

I want to get some feedback from you all if you've heard anything about this or experienced issues.

My pump is a 655 and here is a picture of where it will be mounted in relation to the mobo and gpu.

I have a D5/655 and it is mounted almost in the same location with SLI 260's nearby and never had an issue.

I agree with his concepts, although I don't think the magnetic field is strong enough to do any kind of damage to your cards or board. If your HDD cage has a drive in the direct vicinity, I'd consider moving it to the top couple slots. Otherwise, I think most components are shielded enough. Remember, even PCB emits some fields due to the design nature of the traces, I can't think a pump would create any issues for you.

Hrm.. Well, he's right about the electromagnetic interference..

Though the thing is, devices these days are so high wattage that the components on their power feeds will just gobble the electromagnetic interference up and turn it into consumable power. That's what all the support circuitry on the PCBs are for..

So I don't think you have anything to worry about as far as your CPU and GPUs are concerned.. Your hard drives are heavily shielded.. SATA and power cables are all heavily shielded from that kind of thing as well.. Not to mention that the SATA standard has error detection and correction so even if it did interfere, the worst it could do is hurt performance a bit..

Just about everything on your motherboard that consumes power gets it's power from mobo power circuitry which can easily filter out and stabilize electromagnetic interference as well so they should be ok..

The things that are MOST likely to be affected are the things that are Analog, not digital..

Possibly if you're using VGA or S-Video output, it could create slight distortions in that, but digital outputs (DVI-D, HDMI, etc) have error correction in them so they'd be unaffected...


Possibly if you were using analog sound output (green) then you could hear a hum or a little bit of distortion on that from electromagnetic interference..

Other than that, I really can't think of anything that would really make placing the pump too close to something an issue..

as long as nothing leaks, it won't be a problem.

I even asked my dad about the HDD's or SSDs and he said that theyre fine even being directly next to the pump as theyre very well shielded.

Im not using any analog or vga outs. I figured it wouldnt be a problem as Ive seen people mount pumps near the same location.

Thanks for the input Would like to hear some more though.

Don't worry about it, the same applies to the motors that turn the fans on your graphic cards and such, whatever magnetic inteference is too small to ever cause problems. Just make sure the loop is tight

Oh I sure will, the only parts that Ill keep an eye on are the 1/2" barbs and 7/16" tubing. Im using compression fittings everywhere that is visible and barbs where they arent. Everything should be solid
