nikhsub1, in the UK, oddly enough the threaded Iwaki pumps have an 'M' instead of a T at the end of the model number. I believe this applies to all 240v models.
Blackeagle, thanks for all the info on your setup. My system too will go in a separate box, with rad, pump and fans in there. My radiator (
Thermochill 120.3) has 3/8" BSPT threads so I can't really widen that, and at the most could use 1/2" barbs on it. I think I most certainly will plug my waterblocks in parallel which should result in a theoretical 3/4" path (2x 3/8").
Here is the layout and specs on the parts for a serial system which I might use to begin with:
The radiator has a 3/8" threaded connection, and so this as well as the blocks is the limiting point, however unlike the blocks (Swiftech MCW5000) this can accomodate 1/2" ID tubing depending upon the size of barbs I use.
To go with a parallel system, two radiators would be required to open up that 3/8" path to 3/4", which would prove an expensive way to reduce restriction:
Not sure whether to use a reservoir immediately, esp. since John Guest sell pushfits with one input and up to four outputs.
Any input appreciated, esp. regarding the effect one rad. would have on flow.
