Eleblyat4 years ago000Is the volume of the expansion tank sufficient compared to a pump/reservoir combination or do I have to order a separate reservoir?Show in original language (German)DarkSide7372 years ago • purchased this product000purchased this productYes. I'm using a custom loop and the pump itself is enough as reservoir. I have the additional reservoir still in the box because is not necessary.CommentDarkSide7372 years ago • purchased this product000purchased this productYes. The tank itself is enough for CPU + GPU if you want. I'm using only for CPU and took about 1/2L of coolant in the loop: CPU block, Corsair XD3 Pump and Corsair 140x280mm radiator.CommentBen30004 years ago • purchased this product000purchased this productYes, that's quite enough.Show in original language (German)Commentzwerbel4 years ago • purchased this product000purchased this productIn my opinion, the container is sufficient.
