Aluminium + copper loop

[DaveCad919]

Hey!

 

I am a total beginner and messed up with my custom loop. I bought water parts from this one local craigslist seller and thought everything would be nice and compatible. Some of the parts were brand new as well.

 

So I thought nothing and built my loop. Turns out, I now have mixed aluminium and copper. The 2 rads are 360mm x 27mm aluminium, while my CPU and GPU blocks are copper. I’ve been running this system for a week now, no issues and the temps are good. Am I f*ked though? I was thinking about swapping my rads to copper asap..

 

Fuel used: EK cryofuel clear, says atleast in the description that is has some anti-corrosion additives, but from what I’ve read so far, it’s not enough?

ummmm you should probbably use all of one metal

It can work, like you see in every single AiO... I once had to refill an AiO and just used EK Cryofuel for that and it worked fine for years... BUT, galvanic corrosion is a thing and it might impact the performance, especially of the rads and in the worse case it can lead to leaks... If you can I would sell the rads on eBay and buy proper copper ones...

Noone wanna buy a recently corroded radiator. Even with long wash theyll still corrode.

Swapping to 280mm x 45mm copper rads. Only ran the aluminium rads for a week, have I potentially damaged my blocks now? Or will I be fine if I flush my system and swap to copper rads?

Flush fluid, run distilled water through everything, then replace with a good coolant. You'll be fine.

i would swap them with copper rads ASAP, unless ya wanna run high glycol ratio coolant (ie car coolant)

 

cheap rads are bykski CR-RD360RC-TN-V2 or barrow dabel-20b

 

remember to flush them
