Hi Guys!

I have some questions as to what Watercooling system I should use for a HP Z800 Specs below....

2 x Xeon X5670 CPU's (1366 socket)
1 x EVGA GTX 980 2.0 ACX (non superclocked version)

My main issue is space and would most likely require a dual bay reservoir and pump and the radiator to be placed externally due to lack of space and modding with the Z800 case. (but if you have any suggestions i'd be grateful) See pics attached.





The main reason for wanting to watercool is because my internal temps are a tad high I believe, and wouldn't want to risk frying the GTX or my CPU's. I do a lot of 3D Rendering and have the system running pretty much 24/7.

I also have an issue with the fan noise on full load, they're way too loud under load so will possibly swap these out for some Noctua fans or something similar.

I appreciate any help you guys can give me! :)

Cheers,
Jon.
 
I may be wrong but i think you might find this very tricky.

The Z600/800 were designed for businesses, and poking around mine a few years ago (Z600) the design takes a very modular approach. Meaning everything that needs to go in there slots in just where it needs to, just as you mention - you really don't get any empty space.

That's fine you say, i'll move it into a custom case with lots of room. Now if i'm remembering correctly this is where you'll run into the problems. Due to the modular design, the PSU's were also custom built for these models, along with a custom design motherboard. So even though having a larger case may make room for watercooling components, you might find it a real pain to transfer over the components from the Z800.

How hot is it actually running under heavy load? You do have the luxury here that HP designed a dedicated air flow component, something that doesn't really exist in the custom world.
 
Cheers guys for replying,

The z800 has a AIO watercooling unit for the CPU's which I can acquire for around £250 (I begrudge paying that for something that is closed loop and no expansion to the GTX).

I was thinking that an external reservoir/pump would be best but was hoping to not spend in excess off £350-400 for everything, 2 x cpu blocks/tubing/gpu block etc. (although this can change if really needed).

My temps when under full load reach around 88 degrees on the CPU I know that's not really anywhere near the TDP of the X5670's but my previous graphics card (seems to have) died due to overheating when I was rendering an animation for 3 days, looks like the internal temp of the case killed it although It may have been just a dud card on it's way out but I don't necessarily want to take that risk with a new £300+ card.

I don't want to transfer it to a custom case really because like you said the PSU is custom built, the motherboard wont just attached to a standard PSU (I have seen elsewhere that someone hacked it into a case but had to splice the PSU connectors etc and had some issues with it throwing some errors at BIOS) Not really my cup of tea.

I do have the airflow channels that you are talking about in place when the system is closed up, but took them off for the pics.

Cheers,
Jonnie.

In that case you could always put a rad on the outside of the case and just cool the GPU to keep temps under control. Not exactly what you wanted but it's certainly cheaper and wouldn't be as much of a struggle with space.

Would this still require an internal pump and reservoir though? I don't think the GTX has any closed loop cooling to buy seperately at present, I might be wrong.

I know that the GTX can be bought with a pre-installed all in one water cooling unit but I'm unable to find this as a separate component.

i would consider looking at a fully external wc solution (like some of the koolance units?) and then just having the two pipes for the blocks going into the case.... probably from a modified pci bay slot?
 
Thanks zeegy, I was thinking this might be the only option too. I will see what the bank manager says (My Wife) :) and hopefully this can be a go ahead pretty soon. I will keep you guys updated once the decision has been made :)
