Single or dual loop?
 

Hello,
Just finished my new rig with an external box. Right now I have a block for the cpu and another for the HDs.
Before the external box everything was crammed inside my case.

Because of that the HDs were heating too much, so I decided to make a block for them. To get more space I used and old case and moved the radiator and pump/reservoir to it.

My problem now is that my temperatures increased a lot. I understand that my pump is not good enough I believe the head is about 1.5m, and because off all the plumbing even less, so I'll replace it with something bigger.
My question to you guys is this, should I replace my radiator from a single fan to a 3 fans, get an Eheim 1250 and put all blocks in series (cpu, gpu, chipset, HD)?

Or get another 1 fan radiator and get 2 other pumps, say 2 CSP-Mags, and run 2 loops in parallel, one for the cpu and the other for the other blocks?

Thanks.

i would actually check how much flow you get though those valves
they look resrictive

i would do 2 loops. you want as little heat in a loop as possible and if you can do 2, then go ahead. what kind of radiators are those anyway?

The valves are not as restrictive as it looks, I searched the quick disconnects here in Brazil but a pair of them would cost 4 times what 2 pairs costs in US. So I had to adapt something cheap to get at least some of the functionality a quick disconnect would give me.

I'm thinking of 2 loops as well I'll have to make a new external box, probably with wood, but I guess it will work better.
These radiators are designed specifically for watercooling, the guy that makes them has 3 models 2x120mm fans, 4x120mm fans and 6x120mm fans.
Mine is one 2x120mm but I'm thinking of getting 2 new ones of 4x120mm instead, to get me more overclocking possibilities and to be able to cope with the heat of the gpu, chipset and HDs.

Thanks for the tips.
