Xtreme Triple PA120.3 Cooler

[phelan1777]

I was under the impression that Iwakis are to only mounted one way, as any other mount would not be ideal for performance, and possibly damage the pump?

[CyberDruid]

I have read the PDF. I ran one mounted vertically for 9 months. No harm.

These are mounted horizontally. The concern is two fold: that no air get's trapped in the pump chamber: ideally you would want the outlet facing up to facilitate that...but properly filling the loop before starting the pump is another alternative.

The second is that there could be wear associated with the thrust surfaces mif mounted vertical leading to premature wear of those areas. So far that has not been an issue.

This orientation is horizontal and the only variance being the outlets are pointed down...but since this is for me and not a client I do not have any worries about warranty/longevity, etc.

I lined the panels with Sonex using 3M 777 contact adhesive and it made a big difference.

Cooler is currently in place sitting over the AC vent running the ST. I am seeing 9-10C lower load temps.

10C is a lot...and well worth the efforts.

Also the greatly increased surface area is letting me run the fans very low...and cannot hear them and I am about 3 feet away.

Once bled in the system is almost silent: exactly what I had hoped.

I eliminated the balance tube and that stopped the aeration. No waterfall...but silent.

I have to say the entire apparatus has exceeded my expectations. GPU temps at idle went from 39 to 27C. It is so much quieter than the last cooler I wish I had built it sooner.

This is the last phase of my Silent PC project. To have this much power with virtually no noise (the Raptors are now the loudest component) was the goal. I had my doubts because almost every rig I have built is a compromise in some area...this time since it is for me there was no limit to the budget and I allowed myself to keep trying until I got it right.

I learned a fair amount in the process...but my intial hunches about angling the rads was spot on.

Soooo anybody want to buy some Alphacool pumps

[The[R]eaper]

unbelievable CD! two iwaki's w/ 3 120.3's

10c drop is amazing while being silent.

damn, you make me wanna build an external box and get an RD-30

congrats to you sir

So do you think the Iwakis with their heat dump is worth it? I mean, all those pumps are doing is pushing water through the rads, not a couple of rigs' worth of blocks?

If you have a decent RAD and run the RD30 into the RAD first then its highly unlikely u will see any affects of the heat dump, unless maybe if you run @ 24v.

There are results from tests run as far back as two years ago with running the RD @ 18 vs 24v and corresponding heat dump.


As I have two RDs now, I might try something not nearly as crazy, but crazy none the less :p;

[CyberDruid]

Go for it.

The cooler is pressing through 2 FuZion CPU WBs, MCH WB, SB WB, and two dual GPU WBs. Although one Iwaki could certainly produce the minimum required I find that increased flow does yield lower temps.

After Folding for the past several hours I am seeing 9-10C lower temps than before. This is with a thick dust filter and the fans on lowest setting. Basically I went from a 35C delta from intake temps to a 25C delta. Ambient is 23.3 and my hottest core is 48-49C under load. The coolest core is 35-36C.

[daedality]

Now that I have my doubts about these pumps...I am considering using a pair of IwakiRD30 and running the rads in series for a single loop.

Here's a question: which would work best

Pump>rad>rad>rad>pump

or

Pump>3-way splitter>rads>3-way splitter>pump

Just kicking that around. Of course I could go totally nuts and just get a third Iwaki...but that seems like too much...I am getting excellent flow with the single pump cooler I have now so I am guessing a pair of Iwaki would be more than enough.

Haha. As soon as I started reading this thread, at your original post, I was going to make a post suggesting that you ditch the pumps and mount a couple of Iwaki's in a single loop.

...and then I decided to read the entire thread before posting. Sometimes it's funny the way things work out.

ANYWAY.

Well I worked until about 2AM and got the unit completed


Here I have the second Iwaki mounted

I have a few suggestions. Definitely leak proof the PSUs, then what I would do would be to mount the Iwakis on top of the PSUs. With the Iwakis lower, you can bring your reservoirs down and mount them inside of the structure instead of having them stick out like that. Then, get rid of the balance tube between them and instead place that third reservoir. I think you'll have a better time with cavitation if you had that between them rather than a tube. Also it would be easier to fill the loop because you could use the top hole of the middle reservoir for filling. It would, of course, need to be mounted above the other two reservoirs. Also, I would shorten up some of those bends (like the one between the two radiators) with a couple copper U-bends like Martin has tested. I get mine at any local plumbing store, just make sure you have the tubing fastened on them tight if you ever use them with Iwakis.

Those are just suggestions though, it may be too much trouble to do all that but I think it would save you time in the long-run.

[CyberDruid]

I like it how it is now..without the balance tube cavitation stopped completely. No more gurgling and crackling like in the vid I link below. Thanks though. Frankly I would prefer 7" of tubing over an elbow any day...but when I do use elbows thw copper ones for soldering pipe work well...especially Martin's with the little barbs.

Everything is working well...there's nothing I foresee changing. I may put a splash guard ovewr the PSUs ... but I don't expect any leaks. Everything is sealed off with EK captive O ring barbs and stainless steel double wall pinch clamps except for the pumps which are so larg and OD that the tubing barely slips over them. On those I used nylon ties specific for tubing.

Last Vid of the apparatus installed.

[CyberDruid]

It's staying the way it is. It works great. It bled in seconds...it runs without cavitation. I am happy. Thanks though.

So what is the final loop order? I'm having problems following it.

[SafeFire]

Jesuschristandagoat, that's some serious cooling power.
You should try and measure the water temperature at the point where the waterblocks would be, see how close to 0 it is.

I must admit that I did like the triple loop better, comes off more "neat", and seams like it would utilize the power of three PA120.3's better when cooling more than a single component.

Give or take, this cooling loop really pushes boundaries for what is possible, and plausible.
I congratulate you druid, you are eXtreme!

[Xilikon]

I love the badass setup You always push the limits of watercooling and case modding to the extreme so great job

[CyberDruid]

Oh I am glad to have gotten this out of my system...now back to case modding...

Final loop is >res1>res2>pump1>rad1>rad2Pump2>rad3>PC

I appreciate all the insight from you waterheads and of course it's always great to hear I am Xtreme..I love that...

It was a lot of long days...40hours in about 3 days has got me a little hungover...scratched, sore the usual..but like rough sex case modding does make you sleep good at night

[CyberDruid]

[zlojack]

That's just phenomenal.

[Polizei]

Hmm... why not run it:

Res1 > Res2 > Pump1 > Rad1 > Rad2 > Rad3 > Pump2 > blocks > Res1

Running the 3 PA's together can't kill the flow that much to need a pump mixed in there. In the end, it doesn't really matter because it still performs great.

[CyberDruid]

I ran the 2nd pump through a rad so as to kill off any heat dump from the pump...no sense in uber cooling the water then heat it at the last pass...

Update on the temps. Now that the heatsoak from Folding has finally settled in my overall drop in temps is only about 7C. But I am still happy.

[Dawgdoc]

CD, to say that you are Xtreme is like saying that Mt Everest is an anthill.

Keep up the good work man. You are one crazy badass SOB and I love it!!

I really look forward to your build threads and learn something each time I read one. You are simply an AMAZING craftsman.

AMAZING craftman!

[CyberDruid]

Awww shucks. The cooler is working great. I never shut it off and having it quieter is a great plus. The Airfilter mat is really doing it's job too...this thing is kind of like a whole-home air purifier too

[Section8]

Wow. That setup is insane. What all are you cooling? A supercharged Hemi? LOL..

[Yeknom]

Wow, insane. Great work.
