To nozzle or not to nozzle?

I bought a Dtek FusionV2 from a forum member and it came with a quad nozzle thingy;

So the question is, should I go with the quad nozzle (as I have a Q9550) or the standard one? I've read that the quad nozzle doesn't make that much difference and that they can reduce the flow and increase the temps of other components in a multi block loop. I've got my GPU in the loop too (full build details in the link in my sig).

It seems to be tricky to find a direct comparison. There was a review on XSf but the images have gone. I figured that there's probably some peeps here with experience of this.

Thanks

This might help (it's only a mirror now as the site has closed down

From memory of reviews the v1 really benefited from the quad nozzle whereas the version 2 has only a very small gain.

As you have suggested, with a gpu in the loop, the nozzle may not be a good idea especially after looking at the second link unless you have a very, very good high pressure pump?

in my experiance it didnt change a thing

Thanks for the replies. That's the review that I was looking for Greebo thanks.

It looks like I'll have to use the quad nozzle as the standard one didn't arrive with the block anyway. Going by that detailed review it doesn't have too much of an impact on pressure drop so we'll see.

I'm using an 18w DDC pump so I'd like to think that has enough pressure in it to overcome this?

your pump should be just fine, I think - depends on your loop, components, elbows, etc.

I have a V2 and quad-nozzle and no complaints. To be honest, opening the V2 and cleaning up the horrendous rubber gasket with a scalpel was more of a benefit than the nozzle.

Definitely worth opening it up anyway to see if your gasket needs stripping!

Why not use no nozzle or am I missing something? Your pump will be up to it as it's one of the best. All depends on the rest of your loop.

Chances are you might gain a degree on the cpu at the cost of your gpu temps.

You have to have at least the standard nozzle or there would be no plate in the centre of the block for flow direction.

If the GPU temps, with the new set up, are the same or better as they are now, with my pump/block set up, then I'll be happy. If not then I'll probably have to get the standard nozzle to try.

That's all assuming that the CPU temps will be better!!
