WB and Gpu pelt with one RAD

[htkm1]

Currently I am running a WB, NB Blocks and a Gpu pelt(80W) with a Thermochill 120.3. I am thinking of getting a WB pelt 226W (Swiftech). Also I will be changing the Gpu pelt to a 172W. Both will be powered(12v) by an Antec 480W PSU. I have another 480W PSU supplying the Rig. the ambient Temp is 26~30C. I stay near the Equator.
It will be running on a loop WB(pelt)>>NB>>Gpu(pelt)>>Rese>>Pump>>RAD.
So my question is;
1. Is it advisable to get 2 x 120mm RADs and // them. One each going to WB and Gpu with NB on either one?
2. With the above loop, how much will the Gpu pelt performance be effected?
Any advice/comments welcome.

Now the only thing i would say that is very wrong inn that setup, would be the power supplys. Does that supply have that many Amps?

For the cooling, the best performance you would get from to seperate loops.
Other then that it should work, but the heat genrated from the 226 pelt is going to warm the water pretty much, causing the GPU temp to rise quite a bit.

You have a large and pretty effective rad, but you did not spec how many fans are on it, nor the cfm of those fans. If the fans are producing a strong air flow (140+cfm actual flow of air through the rad, fans will need to be rated at double that.) through the rad, then it should be able to deal with the load.

I'd suggest that you lose the NB block. with two TECs in the system & after hitting that CPU pelt block the water will not really cool it well, a good air sink like the new Swiftech or Microcool blocks will serve better. And removal of the NB block will also increase your flow rate for the CPU & GPU blocks.

I have 3 x 120mm Fans sucking Air from the RAD. Cfm is approx. 90 each.
Swiftech MCX159 for the NB?

Yes, that is the one I consider the better of the two I refered to. The Microcool will cool about as well, but is louder, from stats I've read double the noise level of the MCX159.

And if you want even more cooling, at the cost of more noise, you can install a higher pressure & cfm 40mm fan than the stock 6cfm fan which gives only 18dba of noise. You can find a Delta 15.7 cfm 40mm x 28mm fan at Sidewinder computers, but it's around 40dba noise. Sidewinder also has a second Delta 28mm thick @ 8cfm and 24dba. And Sunon makes a Tornado 40mm that gives approx 13-14cfm and is also 28mm thick, I can't recall the noise of this one though & not sure of a site selling it.

Last tip in favor of the MCX159 is that I have read that Swiftech is considering a TEC version of it. Would be most likly you could get a upgrade kit if you wished.

There was a review done at Xtreme Systems not to long ago that compared the Swiftech and Microcool if you wish more info on them.
