There seems to be a dramatic difference in flow resistance through certain waterblocks, although there doesn't seem to be a huge difference in achieved temperatures. I'm mainly talking about the top selling 3-4 waterblocks in this instance.
My question is this. How can you put together a WC system with any confidence, if you cannot find someone who has already done exactly the same thing in a system beforehand, and therefore has the relevant experience?
This situation isn't helped by several factors......identical chips with varying temperatures for instance, varying cases, loop lengths changing as layouts vary (even in the same case) and now I've discovered that not all 500 lph pumps are the same, once you discover the head capability!! No rude comments please!
Whilst I've received some brilliant advice from here, and some excellent pointers, is the only real answer trial and error? If so, this could get ridiculously pricey.
