I'm building a new cooling loop thats gonna include an apogee, some maze 4 gpus, and an aluminum alphacool bullseye reservoir. I've been reading up recently that a mix of aluminum and copper in the same loop will lead to corrosion. I already ordered all the parts and they are scheduled to arrive on friday...I wanna get started on the loop this weekend before I start my summer classes. So should I bother sending the aluminum bullseye all the way back to Florida (performance-pcs.com) to get it exchanged for the delrin one, or can I just keep the aluminum version and hope that nothing falls apart?
 
It will have corrosion, yes. However, the corrosion happens over time. Running anti-corrosion fluid (lots of it) will help.
 
for the most part those screaming about this are "chicken littles".

Galvanic corrosion can be a minimal concern if:

-the aluminum parts are anodized.

-you use distilled water with a corrosion inhibitor or a premix like PC ICE.

I ran aluminum and copper together for almost 18 months 24/7 with distilled water with about 20% anti-freeze. Guess how much corrosion I found after retiring the rig?


NADA :rolleyes:
 
OK...so the bullseye is anodized black and i will be using Audi antifreeze...the main ingredient being Ethylene glycol. Would a 50/50 mix be ok?
