Two rads in one loop?

post #1 of 12
Thread Starter 
Hey,

I want to cool a Q6600 and two 3870's. What are my best options?

I don't really want to do two loops because I don't want to purchase two pumps and two reservoirs. Could I put two rads in one loop with just one pump like this? (I would go with a 480 rad but I can't fit that into a Lian-Li A71B case)



Thanks

I ran a dual rad loop before. What cpu block do you plan on using? Gpu block?

As long as you're using fairly freeflowing blocks with a good pump such as the DDC or D5 vario, you should be good.

You can put 2 rads in one loop its just going to add more resistance to flow. If you have a good pump it shouldn't be a problem.

Im no expert but you would need a nicer pump than with 2 loops.

I was thinking of:

CPU Block: D-tek fuzion v2
GPU Block: D-Tek fuzion gfx V2

How does that look? (I would also have a res, but I just didn't put it in the pic)

Hi.

This loop order works well:

Pump > Rad #1 (220) > CPU > Rad #2 (120) > GPU > Res.

Here is an example.

Is that the D5 Vario pump?

Do you suggest only a 120mm rad after the Q6600 or should I stick with a 240mm?

Thanks, +rep

You can't beat the addition of more surface area. 2x 240mm is good.

That's definitely a D5 (get the vario one!)

Do you want to keep it all internal? If not I would just put a 480 on top of your case, or make a stand like I did for mine once and just stood it at the rear of my case...It would be cheaper, I like keeping my rad out in the cooler room ambients also, has to help temp's a little...

Two Black Ice GT 240mm rads are actually cheaper than one 480mm rad on Petra's.
