Okay, so we both agree that lint is a bad thing, and that running an open air loop is a bad thing to do, which pretty much means using a filter in such scenarios, or using a closed loop filled with clean water is the way to go.

If crap from the radiator is an issue, then an in-line filter should be used anyway, if only for the pump's longevity sake even with blocks that may otherwise pass such hard stuff unhindered.

I guess for radiator crap one could argue a point for both sides of the coin. A "lint-trap" block which catch all the hard lint that is potentially damaging to the pump. Performance of the block will slowly degrade, forcing the user to investigate, realise that they have an issue and install a filter anyway. A non-trap block will have particles of matter getting stuck in the pump's axle/spindle contact points causing wear.

In either scenario (lint or radiator crap), they are both issues that need to be made aware of, observed, and addressed if they occur, regardless of the waterblock used (lint trap or open).

Just curious as to what kind of filter could be used, i tried goodle but only could find stuff meant for home applications that wouldnt be well suited for high flow applications.
