AngryAlpaca-
I did not say that I thought the PolarFlo was one of the best, I did say that it looks pretty decent.
A c/w of .17 is not one of the best ratings I have ever seen for a block, but it is FAR from the worst I have seen.
A block with a c/w of .17 should do a pretty good job of cooling a hot cpu.
Will it do as well as a block with a c/w of .13? Not likely as long as all other system variables are unchanged....but even then I would have to say it IS possible.
But it will do better than a block with a c/w of .21- and I have seen far more commercial blocks with c/ws that test above .20 than below.
I have used a couple of different water blocks and personally I think that any block with a c/w under .20 is ample. Lower IS better, as a rule but there are often other considerations that must be made when buying components for a water cooled system.
Would I use a Polarflo block? Yes, if I needed a block and found one at a good price.
I've used a Koolance block too- not as bad as reports made out either, when put into a decent system.
