Liquid Cooled SkullTrail

[s0lid]

Hey cybi how fast is those harpentowns @ 3Ghz?
Wprime times for exsample :p

Wants mi own ST board + 2 x 54x0 chips

[CyberDruid]

cooling the 5000x/5400 chipset to ~0c or colder helps FSB a lot

I'll take the Forum move as a sign then

I was thinking about a chilled loop. But I am not sure the phaser would hang with that.

In the past two days my overal temps have crept up another 3C...I think three seperate loops would be the way to go.

Any thoughts on using a Phase Change unit to chill one of the loops? Possible set uip being Pump/Rad/WB connected to phase/CPU WBs/res

I've often wondered how a phase would work if you just added a waterblock to the loop and clamped that to the phase head...you'd think it would make a dramatic drop in temps right before the CPU or whatever you are cooling...

I'll run some benchies in a bit.

Id certainly love to see someone try a phase change in the loop.. but wouldnt you have to run like 30% antifreeze to stop freezing?

awesome setup tho

[THRASHER2]

There it is: ready to remount inside the Soldam case.

Where can I get one of those BlastFLow X20 adapters

I have since upgraded this to a Swiftech 220 custom kit.

It's going to depend a lot on the evaporator style of the phase unit. Do you have a maze evap or a stepped evap with center cap?

You seem to have plenty of spare parts so I might suggest a slightly different route but, again, this is going to depend on the phase unit and what load it's charged for. you could pretty easily make a HX for your cpu and chipset loops by dropping your radiators into an antifreeze/distilled bath in a cooler and put a high flow waterblock against the evap and loop the antifreeze/distilled through the block on the evap and into the cooler to chill the radiator bath. Depending on the charge on the phase you may or may not need to mix antifreeze into your current loops.

IMHO, you'll either need a custom chiller with big(24+plate) HX evap or a triple head phase to really pull the most from any skulltrail rig.

[CyberDruid]

Thanks for the input. Chilled liquid seems like the way to go.

I got the adpater for the X20 from Vadim Computers in the UK.

[WesM63]

Cyber,
That stupid SB fan annoy's the heck outta me. Do you know of a replacment air-cooler?

BTW, The Blastflow block can be had at NCIX for $119 USD.

[jedson3614]

Why are your temps so high for watercooling

I can't imagine how you would adapt a heatpipe cooler...there are three small chips

Why are your temps so high for watercooling

The Xeons have been running a lot hotter than I expected. I even RMAed one of them because the Core temp difference was so radical...two of the four cores idled at 50C... The new one is more normal but they still run hot.

I'm building a larger cooler with three PA120.3 on three seperate loops so I think that will help.

I have reseated the waterblocks a number of times and used IC Diamond TIM this time instead of Shin Etsu but saw no real difference.

Just too much tubing and not enough rad or pump...the IwakiRD30 and the PA120.3 finally met their match

[STEvil]

Coretemp doesnt read 45nm processor temps correctly. Realtemp does a better job.

Use a common res between the loops so you're not wasting radiator power

[NaeKuh]

wait CD why is this in the TEC section?

Also, how does load temps look with the cards like that. It was tested and on the 8800GTX it was actually a double digit number @ load.

I think fugger was trying to send him a message, lol.

We could probably figure out a TEC set-up for this thing but, even cpu and chipset only would be terrifying. we're talking dual E5420's and a 5400 here so, 320W Qmax pelts on the cpus and an 80w qmax on the chipset. Should be able to run all three at 10v to improve thermal transfer efficiency since we're not trying to dive too far into sub-freezing. but, this is still going to need it's own ~950W 12v psu so something likes of a 1200W ATX psu or a meanwell se-1000-12. Problem then is going to be dissipating all the heat from the peltiers. 320W qmax pelts require about 500W to transfer that much. cranking them down 10v will drop transfer to about 270-280w and draw to about ~440 for each cpu and 90W draw and under 7w transfer. Should keep all three just sub-freezing at load. Then you're just going to need a pair of PA120.3s to dissipate all the heat coming off the hotside. Remember, most pelts you have to keep them below 50C on the hotside or their going to loose a lot of efficiency. I'm honestly not sure if your d-teks can move enough heat to keep the pelts cool.

A tripple head phase unit seems overly complicated for my tastes but, would be a good option. A simple maze evap on the 5400 and a pair of nice stepped evaps on your cpus would work but, it's going to be a monster to keep them below freezing at load given your current temps and the 120W stock TDP each.

I would build a chiller if it were going to be mine. Assuming 220W each cpu and 40W chipset to be on the safe side you're at 480W or 1638 BTUs. The smallest HX I know of are about 6000BTU rated but, keeping the charge down and doing a R22/R290 blend would be simple enough and good for ~-30C with a good 1/3-1/2hp rotary compressor and a rather large condensor. Fan throttling to match load is going to be the hard part IMHO. Most single stage units are only throttling for a load difference of a single processor, not two and a chipset. You may actually need about a 2L reservoir kept pulled down to keep from having a big ripple in temps when you load it. I might suggest a pair of 120mm Kaze ultra 3Ks set up to go full bore at pull down with one shutting off after the fluid is down to temp and the second canrun down to 1500 rpm when the system is idle and throttle up at load. A simple temperature controller to keep the air temp within on the outlet side of the condensor within 10C of the inlet side should work just fine.

come on, you know you wanna!

There is. Good point though.

MADNESS!

That is way beyond my knowledge and ability...but yes I would love to do that..

[ArtosDracon]

I'm sure any of the prominent phase builders would be happy to build one for you for a chunk of coin. I happen to like nol's work personally.

[CyberDruid]

I like his work too...but I am going to have to wait on that "phase" of the Skulltrail build.

I am involved in a number of expensive projects for the biz and just can't lavish the Black Knight with uber cooling yet.

[-Acid-]

Dunno how i missed this thread, Wait its in the Tec section lolol (someone hinting at something i wonder)

Love the build CyberDruid expected nothing less

Why is everyone teasing me with ST build, Wes has one too now
Bloody exp her in u.k tho 420 for a mobo !!!!!

[DarthBeavis]

Thanks Cyber. I am going to order a SB/NVidia MCP cooler for my Skulltrail. I decided to swap out my X2s for GX2s tho.

Great ideas there
BUT, as I own two E5420 myself, I can tell you - they don't drain no power.
When running them at 3Ghz, my whole system pulls 220W from the wall while running prime SmallFFT, and that is with a rather inefficient cooltek 600W PSU.
These Harpertowns have an 80W TDP, but in reality, it's more like 60W each.
Getting them higher is rather a matter of high FSB (and therefore MCH, VTT and Vdimm) than it is of Vcore. Feeding those CPUs more than ~1,3V would be pointless even at 450 FSB.

Great build druid, now you just gotta get some new ram - I can recommend the ones I have, very cheap but seemingly very good Buffalo 800 FBDimms.
They cost me 60€ per 2GB stick, and if my mobo isn't somehow throttling them, I can pass memtest at 900Mhz 5-5-5-15 with 1,9V.

You can find the exact description of my build here - as of now, I have 430Mhz FSB stabilized. However, I still need a new bios, the Z7S still is VERY buggy.

Edit: Namely, this pic will be of interest to you, because it shows the rams' exact descriptions.

[CyberDruid]

I wonder why mine run so damn hot then.

Thanks for the info. I'll try lowering my Vcore and see if it will still Fold. The Transcend seems to be a weak link.

[jcool]

I don't have Vcore option in Bios, but that's not a problem up to 3,25Ghz, and even then I think my problem is the VTT.
I have two perfectly identical CPUs, both run at 1,16V Vcore loaded and 1,08V VTT...
The only 2 things running hot are the MCH and FBDimm, got to improve cooling soon.

[WesM63]

My kingstons run really hot too.

[CyberDruid]

Well I checked out Real Temp and basically it's just saying Tmax is 95C instead of 105C so Core temp is 10C high. Interesting premise.

But I found juicing the CPU(s) was working to make my rig stable for Folding.

Since I am under 100% load 24/7 I expected some heat..but not 63C. If RealTemp's premise is correct I have a much more acceptable 53C load temp.

[p8ntslinger676]

hell i bet if you ran two 427watters off a 1000 watt meanwell you would be sitting nicely :P but thats if you have money to blow, plus think about the power bill and the fact that you'd have to have a wall of rads
