I think you'll be fine with just the 2x120 radiator alone - but that in addition to the original 120 is probably too much for the pump. I can't imagine why you need more than the 2x120 to cool a cpu anyhow.

I have hands on experience with the H50, I was sort of the one that got the H50 modding going. From whagt I can see, theres no reason for the pump to die form adding more rads.

Just something to keep in mind - if you remove the stock 120 radiator you might actually gain a few degrees as the flow would increase.

This is because you will decrease the total resistance in the system. If you look at the picture below you will see a blue curve - this curve depicts the performance of the pump (not necessarily the h50 pump) - it is not calculated. It shows that as flow increases, the pump loses its' ability to provide head or pressure. Head in feet can be directly converted to psi (just multiply head in feet by .433).

The red and green curves are called system curves - they are calculated. They show that as flow increases the system demands more pressure or head - this is because resistance increases as flow increases. A more complex system (smaller pipes, lots of bends, and other restrictions) is going to require more head as you can see with the green line, which in this case represents a triple radiator system.

Now, where the system curve intersects the pump performance curve is called the operating point - this is where the pump will operate. So for the hypothetical example below, the triple radiator will perform at 68 gph and 8.5 feet of head whereas the dual radiator will perform at 130 gph and 7 feet of head.

I love hydraulics!

thank you for the info cmeeks. i guess i would have better temps with a better cpu block with more copper on it and a better pump with a faster flow.
what would happen if i replace the water with oil? or let me ask different.. is there any fluid / mix that is cooling better? i googled a lil bit and i guess water is the best but i ask anyway..

@ wthbot.. maybe that guy screwed his pump due a wrong installation, what exactly did he do?

I would say you wasted your time. Why not just get another block and pump? You could have built a better loop for much less than buying an h50 and supplemental loop parts.

no.. i did not waste anything, i gained experience. i still can use the h50 in my second rig.
the stuff ive bought was 150$ now. for a complete wc i need about 200$ ( with all stuff i want ) .. so i am still free to decide what to do with no dropped cash outta the window..
