I'd have rather the block been another 1/2" taller and paid another $10 into the price for the pump had I known the flow rate would be THIS weak.
I ran it in about every configuration possible, the only thing I didn't try was to see how much it would actually pump without a radiator, mainly because that information really isn't relevant. If it's a firehose without a rad and a trickle with one, then who cares, it's the performance in a complete loop we're concerned about, not how fast it can drain a bucket.
Its more relevant than you think because RADs dont produce hardly any drag, but a clogged one can really give a bad impresson on the pump lol. I have had a corsair aio unit have some copper clogging the Rad fitting right out of the box before. Not really mad about it, the test them all, I think it broke loose during shipment. And how "fast it can drain a bucket" directly affects how it performs in a loop and it is the best measure of how it performs, GPM, LPM, Head pressure, Lift height, PSI, it all matters! Just trying to help....
