What do the D-tek Fuzion nozzles actually do?

[Crashgate3]

I've looks at LOADS of sites for an explanantion, but the best answer I've been able to find anywhere is 'they restrict the flow slightly' and for the most part it's just the enigmatic 'they make it better'. Nowhere can I find an explanation of what they actually do.

Can anyone enlighten me?

For starters the washer seals the top plate and stops any back flow. The nozzle itself depending on which one, changes the flow making a more turbulent steam. The quad nozzle directs the flow towards the cores somewhat. Turbulent flow has the capacity to remove more heat from a surface. A laminar or semi laminar flow had a greater static boundary layer impeding heat transfer.

i was just about to say that........

Ah right, so they stir up the water and swap the hot water at the edges with the cold water nearer the middle? That makes sense.

I'm planning on getting a Fuzion when I sort my watercooled PC out. So it's worth getting the nozzles then? I'm also planning on running two GPU blocks on the same loop, so will the pressure drop be a problem?

The midplate washer can also bow the base plate ensuring lots of pressure is applied directly to the cores. .

hi i tested a d/tek against a zalman gold and an innovatek g/flow and i found that the innovatek was better by 3c and the zalman was best of all by 7c it did have the quad nozzle fitted this was tested ona penryn quad on a max se on a custom loop just for cpu hope this helps

 

[marscay]

i have a hard time believing that zalman block is 7c better than the fuzion.

 

[roller]

i tested a q660 and a q685 both lapped the 6850 was an es i work for myself and i have no reason to xagerate the findings were what i found and no matter which block is used if the loop is of a bad design yure wasting money chasing around after blocks as the block is the end of the chain

Eh?

Screenshots please?
This is my loop with a d-tek fusion using quad nozzles but bear in mind ive also got a ek8800gt block in the loop cooling a G92 gts ...

Do you live in Alaska or summit?

 

[YZFAndy]

Who has added a nozzle kit later and how much did it drop things?

 

[Cob]

I did, but I also added an X1900XTX to the loop at the same time and can't really comment.

Me? ambient was 18C, you wanna see them on a cold day

Tbh i think this thread is a wind up, obviously can't back up claims with evidence

your cpu can't be below ambient without sub zero cooling basically thats what he's getting at. Its literally impossible for a normal watercooled pc to cool to much less than probably 5 to 10 degrees above ambient at the very very best.

And how cant it be? you seriously think i would have my room that cold to drop temps when there low enough ..

 

[matt100]

not at all, its very simple.. either your room was below 10 degrees, you were using chilled water or your temps are being recorded incorrectly. Its physics, they're pretty simple rules.

 

[drunkenmaster]

can you not understand that a cpu will NOT IN USE be the exact same temp as the ambient temperature of the room. it will NEVER EVER be lower, then when its turned on it IS the heatsource, it heats up the room, it will never be lower than ambient temp.

I really can't see how people don't get that and constantly show temps below ambient saying how good the cooling is.

As for the zalman/inno/d-tek comparison.

considering theres hundreds of reviews of all blocks which mostly show zalman, inno, thermaltake, gigabyte, coolermaster watercooling to all be pants, somehow i think me, and everyone else will take multiple full reviews with testing procedure, temps, ambient temps, water temps and spec all listed, over random guy in thread saying the zalman block is the best.

not to mention the rest of the response was largely wrong to. the loop past a certain point doesn't make almost any difference, for just a cpu a 120mm rad and 3 x 360mm rad's won't make much of a difference, a loop that gives 2litres per min and one that does 10lpm is also shown to make next to no difference. you need a basic loop with a pump thats not underpowered, then not much else matters. even between the best 10 waterblocks of the past 2 years we're only seeing 2-3c difference tbh. the bowing makes very little difference, and so do the nozzels.
