new rig for a long time lurker, some ?s for the experts I see here.

Dgephri · 09-16-2005, 03:15 PM

Been reading here for a long time.

My latest Mod project will be in a MountainMods Clear case that has yet to be released.

It rearranges the ATX standard so the Opticals, HDD, and PSU are in the bottom, and the Mobo sits flat above it. Quite a bit smaller than their cubes, but not MiniATX or Shuttle sized. Uses full size PSU and mobo.

My questions are regarding overall perfomance/quiet with a group of blocks.

I have been talking to Rokk at DD, and he is willing to work with some of the customization stuff I will need.

Planned:
WC SLI 7800GTX-spacing dependent on the motherboard to be purchsed
WC the CPU (maybe Pentium D engineering sample-crossing fingers)
WC the NB?
new HDD WB that DD has coming
new single pass Rad that DD has coming, 2X120mm in size.
DD CSP-Mag 12V pump (is this enough oomph?)

I might only do a 8-10% OC, and quiet is important as is stability.

I know the selected blocks works out to a moderate amount of resistance in the loop.

I prefer 3/8" tubing since my space is going to be fairly tight for the rest of the Mod to work out.

I think I can complete the Mod layout such that the Dual Rad won't be using Case air, but will be "on top" in a separate 4" deck above the mobo and using direct outside air.

Thoughts? Comments? "you're an idiot"?

How can anyone comment? An unseen case, customised or unreleased DD blocks. How can anyone say whether the pump will be enough? And what is enough? Is it enough for the system to work or do you want sub-40C temperatures?

good point

Dgephri · 09-17-2005, 02:11 PM

ah, I see your point as well.

DD SLI 7800GTX coming:
http://www.dangerdenstore.com/produc...9&cat=0&page=1
Pretty much the same as the 6800 Block they make, and they will be mated together much the same as the SLI 6800 set up:
http://www.dangerdenstore.com/produc...hp?imageid=290

Just spaced whenever I select my motherboard.

I will post the Harddrive block ASAP. That and the Single Pass rad are due up soon.

I suppose I should have waiting and put up more specifics.

My current WC system (NF2-Barton CPU-5950 GPU-single 120mm Rad w/Stealth fan) runs mid 40s, and OCs decently with really low noise.

I would want a similar compromise here. Even though my 7800GTX stock is pretty quiet, I want to minimize what I can.

I'll post up the linkage for the other stuff when it comes in the following weeks.

just becasue they are coming out does not mean that there is any good data to work off.

A signe mag is not going to be enough. That setup is going to have to disipate 300w worth of heat and is as harsh a test for cooling that i could imagine. Im not sure that rad is going to cool well enough without a large temprature differential given that perfromance is probably going to worse than thermochills.

my 2c

SLI is a gimmick. The benefit isn't worth the hassle, especially in a WC rig.

HDD's don't need waterblocks. Another waste of hassle factor/flow. I suppose it would be useful to ensure longevity in a 10K rpm drive that was seeing heavy use in a tight 1U server rack. But servers use redundancy so it's a non issue.

Get a decent passive block for the NB.

PentiumD's thermals suck compared to AMD x2s.

Getting fresh air to the rad is 'must'. Shrouding is important too.

maxSaleen · 09-18-2005, 08:21 PM

FYI: The 7800GTX will put out LESS heat than its predecessor. I also say forget NB/HD watercooling. A good passive block should handle your NB as long as your case has good airflow. Also I don't think it's worth it to have a full cover block, especially considering this board uses DDR3 memory that runs very cool. Passive air heatsinks will be more than adequate. Go with a GPU only solution from (MCW whatever) or a Maze 4. There is also a new GPU block on cooltechnica going under the name AquaExtreme that looks very promising.

The Pentium D's thermals do suck. If you really want quiet, go for two PA160s with undervolted panaflow L1s. Good luck fitting that into a small case. Which reminds me, a photo of the case would really help us help you a lot.

For the HD, get one of those SilenX enclousures (or something comparable). It will cost the same as an HD waterblock, it will keep your drive plenty cool as long as it has some airflow, it won't add restriction to your loop, AND it will totally silence your drive (something a HD waterblock won't do).

....Inhales deeply....

The CSP-MAG will plenty quiet for your uses. I suggest using 1/2" fittings and 7/16" tygon tubing. This is something Cathar swears by high and low. According to him, you get nearly 1/2" flow, with nearly the bend radius of 3/8". Plus you don't need hose clamps with it as it sits over your barbs very snuggly. I have 10' of it next to my desk, I'm just yet to install it into my loop. I can attest to the fact that it bends nearly as well as 3/8" tygon (really the best tubing). While I'm on tubing, as a personal recomendation, DO NOT get primoflex tubing. It really sucks. I have 1/2" primoflex in my loop right now. It kinks very easily.

Get us some pics of that case. After that I (and hopefully the rest) would be glad to give you some more input.

good stuff guys, I knew this was the right place.

I might skip the HDD block and the NB, I probably won't be running Raptors, so the HDD heat is at the bottom of the list. I've run passive NB on my other rigs with little problems, I just wonderd any long term/OC benefits.

SLI: all my other rigs are running 1280X so, yes, on them SLI is overkill (already have a 7800GTX at 1280X1024 on Dell 18" LCD).

I think I will splurge on this rig and go big on the LCD. 20" Viewsonic or something, not sure yet. So 1600X with all the eye candy maxed will be nice to have available.

I know the Pentium Ds are massive Heat sources, but a "loaner" engineering sample at 4GHz might convince me to do it anyway.

I will post up any links as they become available. Kind of sucks to see all the stuff you want to use at PDXLAN, and none of its for sale yet.
