Magnetic interference

[deathstar305]

Hi first time water cooling a PC. Ran great for 3 months. When I flushed the coolant and switched from barbs to compression fittings I ran into an issue iv never seen before. I have 2 Western digital blue drives in raid1. After the fluid change one of the drives kept dropping out. I had Western digital replace the drive. The new drive did same issue. After talking with my local store we thought the raid controller on the motherboard had issues  so I replaced it as well . Still same issue. It wasn't until 7 days in to testing that I ran both drives outside of the case that I discovered the pump for my cooling system was creating a magnetic field that was causing the top drive to reset and drop out. I'm wondering if this is something anyone else has seen before or if this is unique. My pump was 1 inch above my drive.

Interesting.
No, I've never seen or heard of it before.

I mean it is not rare that a mechanical harddrive fails because if magnetism, but I've never heard about a pump creating such a magnetic field.

Anyway, it's definitly good to know for the future.
Did you replace the pump or did you locate the drives to a different position so it wouldn't happen again?

My fix was farely simple. I flipped the top drive upside down in the drive cage. Put just enough distance to solve the issue.

interesting!  If you get a chance and you don't mind, see if the other drive that wasn't having issues has issues when in that top spot.  I'd be interested to see if maybe that one drive was particularly vulnerable.

Actually I did verify. I had 3 drives during testing all 3 did it when placed in the top spot.

Nice!  Thanks for the heads up

That's definitely a new one I haven't seen before, I guess it depends on the likely hood of it occurring but not out of the question. Hmm maybe I should reposition my HDD now I think about it as it's <1inch away from my pump
