Adding a second radiator to my loop

[sprout2287]

I'm in the process of adding a second radiator to my loop due to the recent warming of the weather where I live.

My system currently has a mcr320 on it with 3 yate loon low speed fans. It's cooling my q9650 @ 4.1 and a gtx260 @ 700mhz. Temps are approaching 60c under load and I want to cool it more as it's approaching 90f outdoors and I'm not ready to turn on the AC.

I'm using a mcp355 with petras top right now and just bought another pump, top, and mcr220.

My question is do I need another reservior or can I just add the pump->mcr220 after the cpu block, before the reservior.

Loop is currently this way:

pump--->3x120mm rad--->cpu block--->gpu block--->reservoir--->

So my loop would be as follows:

pump--->3x120mm rad--->cpu block--->pump--->2x120mm rad--->gpu block--->reservoir--->


Anybody got any experience with this type of setup. I'm really just trying to overcome any pressure drop added by the second radiator by adding the second pump.

Do I need to just make it a totally separate loop and add a res? I don't have all that much room as it stands (antec 900)

I'll post pics when I shoehorn all that stuff in there too, i'm sure it will be interesting.

Preemptive thanks for the advice and comments.

No need to add a second pump to the loop - rads add close to no resistance.

Also, you don't have to put it in between CPU and GPU blocks - it makes close to no difference as long as flow is decent [and your will be - even after adding second rad].

Thanks for the reply. I've been reading and found what you're saying to be exactly the case. I'm going to be doing some experimenting with temps and such.

Extra parts... hmmm... might watercool the htpc?
