Potential unaddressed danger.

post #1 of 8
Thread Starter 
Ive been out of this community for a few months and Im seeing some interesting tech. But one of the things that concerns me about some of these new liquid coolers is the potential to actually destabilize/harm the CPU by means of magnetically induced current.

Im speaking of the liquid coolers with the pump directly over top of the CPU. If the motor in this pump is a brushless DC type with the magnet spinning(like many case fan motors are configured), then what you have is a magnet, passing over hundreds of millions of little electrical connections, in theory inducing some level of electrical current in each one as it passes.

This could cause noise, interference, flips in logic, many types of disturbances to the smooth and stable operation of a CPU.

It may not be huge but if the magnet spins I believe this is a very real possibility.

Perhaps the cpu and waterblock are shielded with some sort of high permeability magnetic material such as MuMetal, even so, I would still be cautious about it being close to my processor.

Just some thoughts, anyone know anything about this?

Interesting notion but I would think we would have heard of any ill effects by now. I would assume that the manufacturers of those coolers have designed their products with the proper shielding to prevent this from happening. Don't forget that in between the pump and the CPU is a hunk of metal to draw the heat away from the chip, maybe that's enough to shield things properly on its own. I would also assume the CPU's heat shield does some of that work too.

Interesting thought, but never heard of any problems.

Yep, there are some things in between to help shield the chip from magnetic fields, but if it isnt ferrous metal I dont think it would have a huge effect.

Im about to do a bulldozer build and I was just going through things in my mind to eliminate any unnecessary instability issues. An electric motor that close was just a red flag to me.

I thought we wouldve heard about it already as well but when 99.9% of the people who own computers dont know much about electricity/magnetics, they may be experiencing instabilities and attributing them to the parameters of their OC, endlessly adjusting settings when the settings may well not be the culprit.

I'd say the only people who would even be able to tell the difference are those who have and try both types of liquid cooling systems, those with pump on chip and those with pump elsewhere, while leaving their OC settings intact.

wouldn't the copper waterblock act as a Faraday cage and block most of the magnetic interference, just a thought not my field. see what I did there

Good thought, perhaps. I suppose its all a matter of proportion, to me though, when dealing with components only a few nanometers in thickness it may not take much to influence results.

What you did there, I see it...

The copper block and IHS would block a certain amount of it, plus the motor in those pumps is pretty small and weak. It may have an effect, but it'd be pretty minor all things considered.

I would think if there were a problem it would affect all people with the kind of cooler(s) under discussion, whether they OC or not, or at least a significant percentage of them, and the cooler manufacturers would become aware of it quickly. It is however conceivable that there might be a tiny increase in the rate of computational error which is still caught by the CPU's internal error correction and thus isn't noticeable by the user.
