On a side note.
For the low-flow test what exactly were you proposing.
We supply pump, block, an tubing and we use a common rad and fans ???
Or do we supply a 240 rad and we use common fans ??
Or we supply a 240 rad and fans ?? (I assume you are no going to ask us to use low volted papst fans for a performance test...)
For the sake of interest in nothing else I would like to see the "middle type" included the convergance of the the two types, the AC cobra if you will

that Pug offered..
What pump block and rad are you proposing ??
From my point of view (and remember I admit to knowing nothing) If we used a common radiator and fans then the only variables are block and pump (and obviously tubing) so noone can come crying afterwards....
