Whats the difference between the Alphacool NexXos

XP
HP
XP Light

Looking at them, it seems its the top material, Copper, plexi , Delrin

anyone any other ideas as to why ??
 
The Copper Top is a heavy block, so for some applications it isnt too suitable.

Also if you have Aluminium in your system its unadvisable to mix Copper/Aluminium as they have a tendancy to react with one another.

but they all have copper bases, which i want anywho....

i have an all copper loop, and dont want to change that tbh...

gonna go with the light if it is indeed a copper base, with delrin top, which i cant find anyone to confirm :o
 
get the full block, its got a better performance rating AND a higher thermal tolerance, i.e. if your pump fails your nexxos block would have to get to 200oC before the cpu blocks seals would fail and of course your cpu cut off would activate long before this. cheaper blocks tend not to have this safety feature.
 
HP - this was the older alphacool cpu block and has a diferent flow of water throught the block. Me thinks it has a different base too.

XP - this was the newer model and available in different types. Theres the XP bold (which has a clear plastic top - not sure which plastic tho). And the XP light and the XP (both of these are more readily available). All i know about these 2 is that the XP light has a diferent top (the standard XP i think has a brass top) and doesnt perform aswell as the XP.

Note - I cant rem the materials off the top of my head so made semi-educated geusses.. all i know for sure is that the bases are copper :D

As it stand me thinks XP > XP light > HP in terms of performance ... just my 2 pence.

xp bold ^ ... doesnt look to have higher pin count tbh (or are they the nozzles :o :p )

think i'll go for the XP nickel plated copper top variety... LGA775 mount (how is the mounting system btw ? it looks a bit flimsy)

mountings are fine, they clip on to the cpu cooling bracket (brack square around the cpu socket)
 
The xp bold is the one of the newer ones and isnt as restrictive as the old ones. It has a plexi-top which is the only bad point about this block although it is nearly 1cm thick so unlikely to crack. I got one of them and can confirm they are very good - keeps my dual core with 5 degree diff between idle and load with 1.6v. I use an eheim 1250, maze 4 and 120.3 rad

not a fan of acrylic tops, they give me the heebee jeebee`s :(
 
Yeah thats what put me off as well but it performs on par with dangerden tdx blocks and LRWW when they are using 1/2" tubing and the nexxxos 9/16" and so should be a bit better once running on 1/2" tubing. Im going to make a new top for mine out of copper in the lab and then do away with the plexi top but it is a cm thick so unlikely to crack that quickly
 
(or are they the nozzles)

Yes... they are... firing over a square grid array over the core center - baseplate on all 3 blocks is same as this one:

XP Bold is same block as above, but with a copper nozzle plate instead of a plexi nozzle plate. The NEW revision of the plexi-top model has better nozzles and will outperform the one with the copper mid-plate by the looksa things... has a circular nozzle pattern rather than a grid nozzle pattern aligning to pin intersects.

So, XP, XP Bold and XP Light all have the SAME base plate. It's the midplate and top that changes. XP top is nickel plated copper fer bling, and also outperforms the others due to additional channeling on the underside of the midplate and a slighlty different nozzle array iirc. Difference is always in the nozzles, not the pin count afaik.

with regards to cracking plexi-glass, thats highly unlikely as its a very very strong and heat resistant material, im confident you could use nexXxos block for as long as you wanted with the plexi top and you wouldn't see any problems

its not the plexi glass, its the seals under it. if your pump stops plexiglass doesnt absorb heat very well which means most of its going into the cpu block and the rubber seal and i would bet my pc that the seals would fail at a much lower temperature than that of the Nexxos XP block which has a nickel plated copper top.
 
yeah those rubber O-rings, they claim temperatures have to reach 200*C before they give in, but whether its true its another matter :rolleyes:

if they use a high density rubber/polymer mix and the outer shell absorbs most of the heat i cant see them hitting their melting point before the PC shuts down. :)
