2 Dual Radiator or 1 Quad Radiator?

I have a motherboard that can get a stable FSB up to about 450... and I'm thinking of getting a q6700... I wanted to be able to OC it past 4 ghz with a water cooling

I would also connect the loop to my NB and my gpu... would the Black Ice gtx 480 work ok for that loop? Or should I get 2 double radiators? Which would give better performance?

PS. accidentally started this thread in wrong section so sorry if you've seen this before

i would say 2 duals, and put the radiators in between different blocks

than again, i have no experience with water

That is a very good question. At some point I plan on getting a decent water set up, and have looked into the quad Rad. Looks very nice, hehe!

Now there was one option I liked, that would indeed go quite well with said quad Rad!

How about a dual fan Res/Rad combo and the Quad Rad? That appears to be my plan so far.. and why not? Makes the res put in some extra cooling!!

Hehehe, enjoy!

nice... only adds 30 bucks to the loop as well :D

hehehe, hey, you can get a normal res, with no added cooling besides for what dissipates via the plastic, or design material.

Or, you can get a res that can add two fans to your loop, and get things cooler. As I was gonna do a full loop, I figured, CPU, NB, Res/Rad, then Video cards, then real quad Rad before back to the CPU.

I just need to get all the items together and order mine, too!

The single quad is likely to be less restrictive than the two doubles. However, I think the difference would be negligible. Do whichever is easier to mount.

It's not that difficult to see which is the better solution. With dual 120mm rads placed after the CPU and then one after the NB/GPU, no major component will be made to suffer from the tremendous heat generated by the other.

Phreejak is likely right that 2 duals are better than a single quad on this. You will maintain more evenly balanced temps, but in all honesty, the 'super heated water from one component blasts the next' argument really doesn't take shape with water cooling. Water has such a great thermal capacity that you aren't going to see spikes in temps from 1 second to the is a gradual cycle. For instance, my Q6600 runs about 48C at the hottest core on load, my GPU (9800gtx) gets only to about 46C on load...and it comes after my CPU and NB block in my loop.

To be honest, you probably wouldn't see incredibly different results due to similar surface area cooling the same amount of thermal output from these blocks. Either way, you still have to cool X-number of cooling blocks with the same (average) surface area of 1 or 2 radiators. Before or after a component only decreases (slightly) the temps going to the next component, which will still have residual heat from previous cycles anyway.

With a decent -> good cooling loop, you are moving a relatively decent amount of fluid every minute (~400L/h or ~7L/min) At that rate, regardless of your radiator, you would be better off with higher quality (higher CFM) fans than anything. Your radiator surface area is constant; airflow is your variable in this equation.

well i have 2 360mm rads and they get very restrictive im useing a alpacool ap1510 which has one of the best head preassure and the amount it can pump arround is really limited by the 2 rads so if you do want 2 rads then i sujest you spend atleast 50 quid on a decent pump or 2 pumps. wc the gfx card has no real use apart from noise.

I haven't seen any rads lately that seemed to be restrictive. Which ones are you using? I always thought that your smaller blocks (NB, MOSFETS, RAM, etc) were always primary restrictors since they have very small block surface areas...even elbow bends are less restrictive than those.

Running high volume pumps with smaller tubing can also be a problem if you use those tubing 1/2" to 3/8" or 1/4"?

im useing 1/2" all the way through the cpu block is a ek supreme which is very restrictive at high volumes the 2 rads are i think blackice gt stealth 360mm and i have a 250mm cylindrical res. i do have about 7' of tubeing though.
