Watercooled A8N32

Upgrade time - and yes I know it's old tech.

I've got a nagging desire to finish this rig off to my own standards. That means it looks good, performs good and is complely finished, etc.

It's got a Opteron 185, 2GB of Mushkin Redline, and an 8800 GTX, so it's no snail.

However, ever since I bought the Abit Fatal1ty AN8 SLi, I've had regrets. The board is a great board if you're looking to run it at stock. But for overclocking it just doesn't cut it.

Running 1.55V through a dual core CPU hits 75 degrees on the VRM sensor. The mosfets are cooler than they used to be - although nowhere near as cool as they should be. I forked out for VRM waterblocks, and I'm now convinced that not all the VRMs are cooled in any way at all. Either that or they just simply aren't up to the job.

So, while I still can, I'm going to swap out the motherboard. After a few nights reading it seems the best one is between a few boards, but the A8N32 is certainly up there. It's also the only board still available new. I had thought about eBay for a second hand boaard but I'll give it a miss.

The board will be watercooled. While I'm at it, I may as well change to a Cuplex XT DI. Couple of reasons for that. Firstly I want to move from 2 bolts and springs to 4. My board bends with 2 in (although obviously the CPU slot stays flat). Using 4 will (at least I hope so) prevent this. I'll be able to mount to the standard bracket, where I have it removed just now.

I'll cool both of the chipsets. And I'll also cool the mosfets.

That means a total of CPU, GFX, Chipset, Chipset, Mosfet, Mosfet for 6 blocks in serial. Please don't give me any advice that I'm using too many blocks or I need to get a bigger pump or run two loops etc. I don't believe I do, my current setup has 5 blocks and is fine. And if it turns out that I do need to run separate loops or get a new pump, I'll cross that bridge when I come to it.

What I'm after is information from people who've already tried it.

It'll be 8mm P&C tubing, which should make things a little bit easier for routing the tubing.

I'd love to find out -

1) Do the mosfets need cooled? Has anyone run a 1.55 through a dual core and run into temp problems?
2) Can I put blocks on 5 different places on the motherboard without obstructing each other?
3) Photos of a setup like that would be great

Any other comments are welcome - but please I don't want to turn this into another low flow/high flow thread and not get the questions answered :)
 
I've spent a bit of time drawing on a picture of the board in photoshop. Seems like all the blocks will fit. Tubing will be reasonably simple. Just one block to the other from Pump>CPU>GPU>Chipset>Chipset>Mosfet>Mosfet>Rad>Res>Pump.

Thankfully the board will work with the GFX card in either slot. So it'll go on the one furthest from the CPU, which makes tubing easier.

The only problem I can't think of a way round is connecting the two mosfet blocks. There doesn't appear to be enough room for two right angled connectors.

I'm really keen to get the tubing exactly right. Have no excess tubing and not have it waving all over the place, etc

Any suggestions on how to link the two blue bits as neatly as possible would be welcome.
 
hmmmm..thats really a tight spot..kinking will definately be an issue if you dont use coolsleeves. OR you could use a F or Y splitter to link those two.

If not then try something like this to minimize kinking and improve flow between blocks.

check to check or X to X ( I understand youre trying to minimize crossover but thats the best way i can think of) :)
 
Yep, I think that would work. But it's still staying as Option B. I prefer Option A... I just don't know what it is yet :p
 
i am a bit worry about your temp, you got too many stuff in one loop

but I am curious about your result, as I am using this mobo also
 
Ah, someone else with the same board, and watercooled.

What parts of it do you have cooled, and how are temps?
 
If your using AC fittings it's a piece of pie. What blocks and tubing are you planning on using?
 
AquaComputer blocks, AquaComputer P&C fittings, AquaComputer P&C tubing.

Don't keep secrets Top Nurse. :)

Likely it'll be a Cuplex XT, either the normal or the DI. It'll be a couple of twinplex, and a couple of the Asus mosfet blocks, along with a 8800 GTX block.
 
You need 45 degree G 1/8 push-fits and all will be wonderful. I got mine from McMaster-Carr.

So with 45 degree fittings, I can tube the two mosfet coolers together you think.

Interesting :)

Time to see if I can get hold of any.

Not exactly easy to navigate their site... And I won't be in the US until November at the earliest, so I'll need to find a UK supplier. But I'm liking the idea of these 45 degree fittings,
 
Thanks a ton TN :)

Bit of a concern though. Those fittings are for compressed air. Will water be ok in them?
