There are no decent water cooling suppliers in SA ... I found that THIS
is probably the closest we will come to having a water cooling supplier in SA and they don't stock full water blocks for GPU's and they have like 1 CPU block available .... they do have rads and res' though.
You can also try contact XS-PC
as they should be able to give you an official supplier in SA for a GPU block and other goodies (I am contacting them tomorrow)
What were you trying to cool with your WC setup that you saw no results ??? ...
