Will a MD30RZ effectively pump chilled (12c) water around a cpu (apogee), gpu (ek x1900), mosfet (mips), chipset (ek nf4) and a 30' round trip of tubing?

With ease, unless your tubing is on a different floor!
Although the Apogee wont benefit from high flow rates.
ya , why not change the apogee to something powerful like Storm or MP-05 LE

storm would brickwall an md-30 with 30 feet of tubing in the loop.

And why i think of the opposite?
Apogee like other low restiction blocks need high flowrates to perform their best cause. On the other hand pressure is for restriction.

That diodnt make any sense joe =p
In any case restrictive block on 30' of tube is a bad idea unless youre happy with a trickle of flow.
Anyway, leaving aside the actual flow of a block for a given pump which is a function of PQ and F/PD curve interaction, blocks like a storm wil benefit more from high flow rates than low-restriction blocks. In fact, the storm is pretty much unbeaten at *any* flowrate, the catch being that when you couple a storm to a pump system flow will be considerably lower than w. say a 6002...

that is of little importance as this is a chiller and coolant gets thick at low temperatures, a restrictive block on a chiller is not a good idea. You would benifit from a high flow block like the 6002 much more.
But better question yet why do you have 30 feet of tubbing? Get rid of all that, get am MD20 instead (much less heat dump) and enjoy.

chiller will be outside on the side of my house in weather proof box with fan intake and outlet

whne the coolant in question is water @ 12c i dare you to measure viscosity changes between that and the 25-30c our h2o usually runs at =p

is that question to me? if so I daren't. double dare!

omg... creidiki just dared someone to measure the viscosity change in a liquid....
and damn, i thought testing rads and wb's was hard

I dought he used straight water as it may be 12C with load but without it may dip below 0C. He didnt say but probbably water cut with antifreze.

chiller will be temp controller to hold water at 12c with a 5c margin - water+antifreeze+zerex

Why bother with a chiller for only 12C. A weak pelt setup will net you that much.

why dont you temp control the chiller to hold water at 0C or like -20C ?
i wouldnt bother with a chiller at 12C... because i doubt its gonna get you anymore OC than a Triple Rad

he probbably cant hit -20C even if he wanted to. Not sure what he is running.

chiller is being built by johann.. to hold 12c becuase
1. I can't be bothered insulating
2. I want a chiller so i can remove noise and heat from my study to the chiller that will be outside in a weatherproof box (fan in and out)
3. my oc is "ok" 2.9 on an opty 165
