Radiator Recommendation
 

hello all! just trying to get recommendation of the best rad for the $. I need a x2 120 rad and I'm between the swiftech mcr220-xp or koolance high flow.

basically i understand the difference between them one having a brass core and the other copper.

while brass has a thermal conductivity of 109 units of heat being dissipated while running @ 25c, copper has a 401 units @ 25c, but i would like to know of any issues or bad experiences of those who have used either of these. Thnx.

copper cools better brass is cheaper
simple as that
cooper can turn green and corrode if the loop is not keept clean I would use a silver-kill-coil + distilled water or your non reactive coolent of choice
also if using a copper rad its not a good idea to use a Aluminum block they can't react with the copper causing nasty goo in the loop nickle plated blocks are fine tho
brass while more resistant to corrosion does not cool any-ware near as good as copper I always go with copper or nickel its very rare for a copper rad to corrode unless you are dumping tap water in on a routine basis or mixing iron/steel and copper ...
NEVER USE chlorinated water ever This pretty much excludes tap water!

swiftech makes the best I have 2 of them never a problem at all 5 years now.

But Swiftech still make the best, Right? lol.

Swiftech isn't the "best" they are a good bang for your buck but that's as far as I would go. To this day the best performing 2x120mm rad I have used is a brass heatercore with high speed fans in push/pull with shrouds. If I was you would I would get into the reviews and decide yourself what you want in comparison to fan noise and pump flow.
