Ok guys.. I have a new theory on why this waterblock is outperforming a Maze1C.. First, make sure you've read and understand the results of BillA's article at Overclockers.com
http://www.overclockers.com/articles481/
As everyone learned in that article, radiators have a happy spot for flow rate, sometimes that happy spot can REALLY improve it's performance.
See where I'm going with this? A couple months ago I moved my whole system up to 1/2" tubing to improve the flow rate. I also went up to a heatercore radiator. My flow rate quadrupled, but my temps remained the same. Mind boggling and hella frustrating.
So. The Maze1C with it's 1/2" fittings and nice wide round channels was not slowing my water down at all.
Now although this little block's whole design is to be unrestrictive, the fact is, my water is being squeezed down into a 1/4NPT fitting, which slows things down alot. This isn't a problem for the block, because with it being so small, it can handle slow waterflow without the water losing it's "bite" from hanging around too long. And with the water flowing so much slower, it spends alot longer in the radiator now. And as BillA taught us, slower through the radiator is a good thing.
