Alphacool NexXxoS XP waterblock review

[pHaestus]

I am going to give up on getting comments back from Alphacool and just post the review of the block with my personal comments and performance results. That's probably all that anyone cares about anyway, right? The bottom line is the NexXxoS XP is a very nice performer, and if it had a different top plate I think it'd be pretty close to best mass-produced waterblock. A lot of the other reviewers and comments by salespeople have misrepresented it as a "low flow" block. It's nothing of the sort; this is a performance block that is very restrictive and demands a pump with good pressure capability (and a properly configured loop) to really shine. German blocks can't be all stereotyped as "low flow", guys.

Edit: Joe - It all works now Vbb and PHP5 play nice now

Start of third last paragraph:

"I shall issue a large caveat that this is just a theoretical model and is, as of now, fully validated."

I think you meant to say "not fully validated"

Looks good!

"CPU Alphacool NexXxoS HP Pro S. A"

what about that 1 but do the jeting in a middle plate not just under the barb

some 1 up for makeing 1 of these a new middle plate?

I am wonder whether it is the same one with just only plastic top for socket A?

Cathar: Fixed thanks

flatline: I BELIEVE that block has a thicker bp and performs somewhat worse. I actually have that block but don't have any barbs that're designed for it.

alex: It is my understanding that the linked block is the same but with plastic top. Alphacool could clarify

[redleader]

The HTML on your news post looks a little broken to me. Could just be the library machine I'm posting from though.

tnx just my 1st thorts on what i see

(regarding xp) but am correct in thinking thay cud use that tipe of hold down and thus be able to have a central inlet? i meen what do u think the actual point of restrisction is the(jet) holes or the tiny gap under the inlet?

(regarding hp pro s) was it the base thinckness or the size of jets (look like pin holes and not menny ither)in your opinion. also in the pic i psoted it looks to me like thay have restricted the outlet if this block can i tell me what size hole im looking at there (as u have block)

tnx 4 your time


oh and congrats on another review we can actualy trust

[psychofunk]

Hey what size barbs are those you used?

[lolito_fr]

Wow I even get my name in a pH article

i meen what do u think the actual point of restrisction is the(jet) holes or the tiny gap under the inlet?

Both are restrictive, but only the jet holes are useful restriction. The shape of the inlet is basically wasting power. (well it certainly looks as though it is)
If this block was optimised like a Storm G4/G5, things could get quite interesting

[flatline]

yea thats why i thort adding a middle plate to the "HP Pro S. A" and looseing the 12? 1mm? holes under inlet in faver of a open aira at bottom of inlet and adding a thin 3mm? acrilic jet plate with the same patern of 20 holes also.. after looking at some info on pins (Roscal's?) shudnt the pins be aranged in an "XXX" not a "+++"
for turbulance sake? :shrug:

[lolito_fr]

Making a new top plate and maybe tapering the jets for the XP is feasable (tempting even...), changing the pins into XXX's is a whole different story! But yes, xxx probably would be better, - a production process issue I suppose(?)

I guess the general trends seen in those graphs suggest a much bigger problem with the WCP testbed than low flow rate, eh? :shrug:

Does anyone know whats under the nickleplating? Is it copper?

Just read on there site that its nickleplated copper, so I just ordered one! I think that the chamber where the jets are can be modded for better flow thwards the last pins.

pH, I think you need some more practice with the camera

[flatline]

alphacool like the revew


maybe thay wud like to comment on the points made in it and also comments made in this thread?

[KnightElite]

I think it's rather funny how they say that Procooling.de reviewed their block

[Output]

Just got the block and wow, is it small!

Did open it and it looks like its not just the jets and the "jet target" area that cause the high resistance. The chamber where the jets are looks so small, and there are sharp edges in the inlet to the chamber. Also where the dimpled jet target area lets the water out is soo tiny, and the outlet contains sharp edges.
I think that this block can easily be modified so that the edges are smooth, the jet chamger lets water flow better, also the the outlet can be modified easily. Since its nickled copper, I guess its possible to do it?

I was thinking of cutting in the top to make the inlet jet chamber bigger and smoother. Also cutting in the middle plate so that the outlet is smooth and that the water that came out of the jet target area can escape easier. What do you think?

[flatline]

link to a top that may only need 1 drill hole



says "for all NexXxoS CPU"

im asumeing that the 1 wuth little jet holes in it pictured in above post juts drill that out and fit it?


what barbs u get with it?

if u mod it up nice gonna send it to ph for a thranshing on the testbed?

[Output]

Does anyone know if I have to remove all the nickel plating or is it safe to only remove where the cuts are? Im scared that nickel will chip from the block and get stuck in the jets...

@Output: i would sandblast everything.

The Nexxos HP pro base actually is the same as the XP base! In the time when the XP was very new, alphacool had a set to upgrade your Nexxos HP pro to an XP. The baseplate thickness ist the same with all blocks from alphacool including the SP (only channels in one direction, instead of pins).
The XP uses 1/4" barbs, the HP pro only 1/8" ones :o - because it has the jets integrated in the same sheet of Plexiglas.

It would already make a nice flow improvement, if you copy the channels of the middle plate on the other side of the topplate.
the onliest thing then is to get good highflow/moderateflow 1/4" barbs.

I produced this ones especially for watercooling issues, but i have to regret that they can beused effectively for 1/2" tubing ( in fact i never tested ). They are ideal for 10-11mm id, thats pretty much for G1/4", i think. I made them more for looks and for practicability, thats why it has the hexagon socket inside, very small od and many barbs (or flukes?) to make sure that the tubing sits safe on it.
The winding is about the half as short as of the standard barbs, so there is eneugh place to modifie the nexxosXP top from the bottom side for more flow on the jet chamber.

[killernoodle]

Very interesting design with those barbs, did you say you turn them yourself?

[davidzo]

if you wanted to guess if i have a cnc at home, i have to disappoint you. I gave a commission to a cnc turning company which made a few hundred of those for me.
They are originally from my company but another staff constructed them (Bambi).

I'm abit torn now, since I'm worried about nickel chips blocking the channels, and I dont know anyone that can help me sandblast the middle and top plate
Guess I'll have to grind it away with fine sandpaper or something!

Those barbs looks great! I've tried to find barbs like that, but I've had bad luck... I now have the barbs from my old maze 2 block on it, but they will only go in like 3-4 turns since there wider at the top!

I don't think that electroplating "chips" off...
