Low delivery head might a problem for 3 block setup. Though I have no experience with pump flow.
 
i'm using the swiftech mcp355 pump now. i see that my mcp355 has a higher delevery head, but lower lph. the xspc pump had a lower delevery head but higher lph. wich would be the better pump?
 
Flow rate will be reduced by number of blocks, how restrictive they are, amount of tubing. Pump with more head will deal with more restrictive loop better. Though I have no idea what kind of affect it will have on your loop, if any.

Flow rate is calulated at 0 inches and nothing restricting flow.
 
...wich (sic) would be the better pump?
You really have to do the calculations. Here's a little chart that shows the relationships between two pumps with different P/Q curves.

If you don't want to take the time to learn this stuff or it's over your head, well, you might want to rethink WCing. Not knowing this stuff is like going grocery shopping blindfolded. ....did you get a box of Wheaties or a box of laundry detergent?

Here's a good discussion of P/Q curves (this article refers to fans, but the principals are the same for pumps)

And you really should read this too..........

As for Zalman and XCPC, well let's just say you'd be washing your cloths in Wheaties and eating Tide for breakfast.

well, i've been WC for years, but i never really paid attention to delv. head rate. just on the LPH rate on pumps. what i have now is working just fine. i've just had the same pump/resv combo for a while now and was looking for something diffrent. i really like pump/resv combo's cause its just easier to deal with in a case.

all the heat from the pump will be going into the coolant as well. Even though its only 10 or 11 watts its still not ideal
 
yea, i'm sticking to what i have for now. up grading to a e8400 so if i see my temps go higher then what they are, i'm just gonna order the mcp655 and just use a T-line.
