Is the pump i am planning to use for a cpu, and gpu loop with a 120mm rad and a second 240. Do you think this pump will be powerfull enough to run this loop or am i best to find something with more power ?? i know this is the pump for a cpu loop with a 240 but not sure if it has the juice to pump through a gpu and second rad.

I don't know the specific data on it, but low flow can result in high temps such as this thread here.

If you have doubts, spend a few more bucks and leave room to expand. Flow will depend on many things such as how the radiator is constructed, some are more restrictive or require higher pressures to be as efficient as desired. A loop has many different factors that effect performance, don't skimp on the heart (pump). thumb.gif

Before jumping onto that pump/RES combo, read several of the forum threads here about the reliability of the 750 pump. It has a miserable track record. If you are within warranty, it's a little down time to swap a new on in. Outside warranty and it's an additional cost. The question isn't if the 750 will fail, but when.

A single DDC-3 with a performance top would have the head-pressure to manage the loop with those RADs easily. Or a pair of DDC-1T pumps with or without performance tops would be ideal since the heat load is around 57C. The DDC-1T is compact and runs cooler than many of the other pumps out there.

D5 is excellent choice, if you don`t have pump controller get the D5 Vario with 5 speed manual control on back. Bottom right corner of pic ( build is still in progress ) thumb.gifbike.gif450
