Noob question no 1 :
So.... using lower Hmax will reduce the cooling "capabilities" ( sorry dunno what the terms for it )?
Generally most probably. The impact of Hmax on the cooling performance depends on how restrictive is the waterblock. High restriction waterblocks need pumps with good Hmax to be able to bring out its full potential whereas low restriction waterblocks are more max flow dependant although you still need some reasonable Hmax (which shud be normal in higher flow, lower hmax pumps).

Noob Question no 2 :
How to classify, which waterblock need high pressure n which not?
By the design of its channels/fins/jets. An example of a waterblock with high restriction is the Storm G4 and the AquaXtreme MP-05.
Examples of low restriction waterblocks are like those who just have a simple single channel passing thru.
