DDC3.2 Pump Top Shootout! 10 tops tested..

[Digz]

I'll give it a try, I've been meaning to try couple out on my old orange impeller DDC2, I have a black impeller DDC also, but it's got a burnt chip and about to go, but if it works on the orange, it should work on the black.

The problem I had on the top of the XSPC reservoir top was the thread depth on the reservoir wasn't deep enough so the black plastic cap threads could slip when tightend alot. I probably wouldn't have noticed in a normal system without a second reservoir, but since my testing rig included a much larger reservoir, that cap has to seal perfectly, or it'll try to leak a little on me.

I wouldn't worry to much about it in a normal system if your reservoir is mounted upright, but I wouldn't want to mount one sideways. I talked with XSPC about the threads, and my sample was previously used, so it's possibly I just got one that was partly damaged.

Thanks Martin

I can't find the post but ages ago on another forum a person posted pics of the tops removed on orginal Black pump and the new Blue pumps when they first came out but when he put the pumps back together he mixed up the tops by mistake and one of the pumps then later burnt out.I can't remember which one but apperntly it was due to friction of the impeller rubbing against the top as the clearance and bore size is different around the inlet so it would be of intrest if XSPC took that into account or soley designed it for the Blue pumps.

I hear what your saying about the top fill cap could have been mistreated before you got it but it's still a concern as people will fill and empty their loops more than once and if it wears like yours has then the res is pointless using if it's not hermetically sealed as your be forever topping it up or having to change the water when it becomes contaminated and turns to pondwater.
