DD Mag vs DD D5

I just sold the Via Aqua 1300, and got a new DD D5. But I need the 2nd pump for my 2nd loop which contains 1 chipset block and 2 HDD block. so I wonder if Danger Den CSP Mag 12v pump is enough for this loop or I need another DD D5.

Koolance HD-55 HDD blocks X2 (can cool 4 HDDs total)
Swiftech MCV30 Chipset block
BIX 120mm Rad
5.25" bay Res
1/2" tubing

the csp should be fine, but for the same amount of money id just pick up a mag5 or mag3 for that loop.
