Best Northbridge and GPU waterblocks?

Jimbo Mahoney · 02-09-2005, 06:21 AM

Hi there,

Still in the planning stages of the system.

I am going with the LRWW for AMD 64 cooling (can't get hold of a Storm G4 or afford a G5).

But what about the northbridge and video cooling? It'll be an ATI X850XT or something, rather than a 6800.

In my mind, it's D-Tek or Dangerden?

If you have'nt already purchased the LRWW, you may want to consider the Alphacool NexXos XP. It performs very well as noted in the Procooling Review (http://www.procooling.com/reviews/ht..._waterbloc.php), costs less than the G4 and can be gotten within approximately 14 days of order entry. I have one on my CPU and I'm quite pleased with the results as noted below.

Load data after 10 minute run of CPU Burn-in with error detection disabled.

IDLE\LOAD
Room Temperature (C) = 23\23
Motherboard Temperature (C) = 25\25
CPU Core Temperature (C) = 36\40
CPU Core Voltage (V) = 2.00\1.98
CPU Core Power (W) = 122\120
CPU Cooling System Thermal Resistance (C/W) = 0.09\0.12
CPU Speed = 2507Mhz

The nexxos needs a pump with good max head capabilities, if you're not planning to run such a pump the LRWW will likely be better.

Jimbo Mahoney · 02-09-2005, 01:21 PM

Ah, I wasn't aware the Nexxos was that good. I do indeed plan to run with a high head pump, if not start off with two in serial. I am aiming for Cathar's suggestion of 23ft head / 3.5 gpm.

Two Aquaextreme 50Z's in series strike me as being rather nice, or two D4's or maybe two DDCs......

Who did you order it from? I haven't seen any US dealers.

Directly from Alphacool - link as follows.

Jimbo Mahoney · 02-09-2005, 03:37 PM

Just found a review of it - looks sweet! I underestimated it!

Since I plan on using two decent pumps in serial , I don't think the pressure drop will be so much of an issue.

I think I've found my new Gfx card cooler too!

Alphacool again? I have one of theri GPU blocks NexXxoS GPX-A and the qulaity is very high.

Senater_Cache · 02-09-2005, 07:08 PM

for GFX, I like the Maze4, especially now that it comes with brass tops or noryl tops. It is also smaller in its height dimension which is good for people with packed slots or SLI.

Other than that I would look at the Australian Fusion blocks. I cant recall who manufactures them at the moment. dang it....

NB blocks, I couldnt tell you anything.
Probably all fairly simliar due to size limits.
Go with non corrosive metals.

scooterfl · 02-09-2005, 07:38 PM

re fusion gpu blocks: Silverprop

Jimbo Mahoney · 02-10-2005, 03:48 AM

Dammit, there aren't very many reviews I can find about Gfx card blocks.

The Fusion, Maze and Nexxxos are all on the list.

Nbridge, I guess it doesn't really matter, but I'd prefer lower pressure drop ones, especially if I go with the Nexxxos on the CPU and gfx...

Z-chip looks pretty open to me.

Butcher · 02-10-2005, 06:01 AM

z-chip is the lowest I'm aware of.

Jimbo Mahoney · 02-10-2005, 06:08 AM

OK, thanks.

I've just ordered my two Aquaextreme 50Z's

Nickd · 02-10-2005, 08:59 AM

Where have you ordered them from? I was looking to get one (only one though) myself, but couldn't find them in the UK. Have you had to order them from Oz?
Thanks, Nick

Jimbo Mahoney · 02-10-2005, 03:50 PM

Cooltechnica

US website, but including shipping, two of them come in under £100 and you pay £100 for two D4's here in the UK, exc shipping!

I'm looking forward to getting import duty though

Jimbo Mahoney · 02-10-2005, 05:28 PM

Thinking some more about the CPU block:

I have had a bad (well, very actually) experience with the plastic topped LRWW. It cracked and leaked onto my lovely 9700 non pro (voltmodded and running sweet) killing it

The reason I was leaning towards the LRWW and DD RBX were the brass / alu topped versions...

Has anyone else had plastic-topped blocks cracking?

My LRWW must have been the copper base bending ever so slightly, enough for the plastic to try to bend with it, and snap.

MaxxxRacer · 02-10-2005, 07:49 PM

Plexi topped blocks will always be prone to cracking. In time they all break. Its from the thermal cycling in the system. the brittle plastic cant take it like metal or derlin can.

With those pumps, if you put the #5 insert into the system you would get better performance from the RBX than the WW. If you use the #1 accelerator plate, the WW will win with those pumps...

And the silverprop is the best choice for gpu. The maze4 is a close second, but has considerably less flow resistance (the reason I chose it)

Jimbo Mahoney · 02-11-2005, 03:26 AM

That's a good point about the #5 and the RBX. I hadn't considered that before, but having just decided on a high pumping head system, the #5's resistance isn't an issue anymore.

That also saves me the bother of ordering the Nexxxos from Europe and its nasty plastic top.

If your referring to the Nexxxos XP CPU block, the top is metal as noted in the Procooling product review. Check the image in the link below.

What makes a good CPU/GPU/NB block? Why do we pick one over the other?
For NBs and, to a lesser extent, GPUs, the "performance" of the block is rather mute as these babies put out so little heat.
Looks? Cost?
I have alterier motives here, I have a design for a NB/GPU block and want to make sure it meets the criteria people want.
This thread is on topic for such a discussion IMHO.

#1 - Doesn't leak, crack, warp or fade.
#2 - It fits my NB / Video Card
#3 - Barbs out perpindicular to chip for NB, out parallel to chip for GPU
#4 - Can be fitted into a loop with a modern CPU block, a twin-120mm fan radiator and 1/2" tubing with an eheim 1250 pump (or equiv) and get flow rates over 3 LPM.
#5 - Cools the chip colder than air cooling does.
#6 - Cheap

Anything else?

Maybe once upon a time (referring to the GPUs). If simple inspection of the increased size/complexity of the current GPU stock HSFs is any indication, I suspect the newer models are nearing the heat output by that CPU in your sig.

I'm a gamer. Speaking from personal experience, I see more benefit from overclocking my video card than CPU (comparing clock speeds between stock and water cooling) so a more efficient GPU waterblock at the cost of increased head loss coupled with a waterblock like the MCW6000 is more beneficial to me. Just pointing out a neglected market.

Thanks, but looking on their website, only the socket 754 is metal. The socket 939 is plastic

I think I'm going to go with a Brass topped RBX with nozzle #5 now, a silverprop fusion HL for the gfx and anything really for the nbridge!

Butcher · 02-14-2005, 09:52 AM

GPUs are nearing 100W heat output at stock speeds, neglecting them as "easy to cool" is not a good idea. In many cases the GPU heat output will exceed that of the CPU.
