experiments in water cooling a mach/vapo

[Jack]

Very interesting!

i will get some K probs on the hx tomorrow so we can look at the temps there as well

I would like to know how the HX is coping as well

[Marvin]

jeeze how much$$ on copper is that ld?

just pm him.

[bazx]

i will fix um on today

5° idle to load, very impressive bazx

[4Qman]

Very good performance. I would be interested to see how it would perform using a 120.3 Rad and Pump with some decent fans on it.

There would be a large amount of heat to shift from the tripple rad. Sacha will you be testing with your water setup when you get the unit home?,.

[M.Beier]

Now thats awesome, I want such a mod once I get the funds

[Pete]

I got some WC kit you guys can borrow if needs to test it all out

PA120.1
PA120.3
BIX 120.1
Eheim 1048 x 2
Laing DDC2
Hydlor pump (asket kit)
Yate Loon med speed

I had the idea of using 2 PA120.1 in a std case. Rads fit on the base of the case okay, this is taking not case is raised off the floor enough to allow fresh airflow in. Anyway radon the base, 1 at the far back and 1 at the far front. Front one can have the coil over the rad so it will have the water flowing through it and also be acitvly cooled via air off the fan on the rad!

Thats basicly a 120.2 setup, fans can run happerly on 7v and 5v and be totaly silent. Get the pump on some aint vibe mounts and your sorted even more! All you'd have is the sound of the compresser.


I think the WC should be in the same box, having it mixing with the PC and outside is going to be too messy.

How ever here is an idea. Gray built me a V2k unit that had a SLHX which i was going to use on my GFX. CPU was -35 at the his testing load and water was -0.8c i think also under load. Now how about it...you make a SLHX add it to the SS so it's all running off the same system and loop and you basicly then have a water chiller and use that to cool the coil down even more. Might be able to get some crazy blends going on then. Then all you'd have noise wise would be the compresser and pump.

I got photos of it on my rig so i'll grab them soon as painkillers kick in!

So manny ideas that could be done here gents!

[maverik-sg1]

My thoughts were to build a res around the existing HX (with current fan removed) and then have that piped through a XSPC 3x120mm rad - the resoning being that you might get great heat dissipation by doing something like that.

But as I am not as skilled/brave/knowledgeable as these guy in such things, I just sit in awe at the work that has been done so far - the results gained prove the worth - nice job.

I will be trying out a single 120 rad first to see how well it performs, then i will use a twin and then triple rad and compare the results of these tests and post, the idea is that if we can have something that can just be hocked up to a water loop and removing a CPU water block then there would be know expense to the consumer as he would already have a water setup, but he would then have a water setup with the added benefit of a silent S/S unit providing sub cooling temperatures.

Anyway will keep you guys posted, but baz has some more work to do with the unit first so it will be nice to see what he comes up with.

[godsgifttoearth]

would you see any increase in performance using a plate HX instead of the coil? i have been waiting for someone to try using water for aaages! the next step would surely be to use passive liquid to air heat exchanger on the condenser side for a lovely quiet setup!

Ya but for the rest of us on load testers bazx, we have no idea the wattage that cpu is putting out, or dissipating into your evap, so your temps look great no doubt, but we can't really compare.

[jinu117]

Primary advantage of heat exhchanging that way would be the fact water can transmit a lot more heat given surface area vs refrigerant. (and we only have so much surface area inside the condenser tubing)
Worth the added cost? Not sure. However, it does give some option on how to cool water part obviously (like what was done here, maybe even geothermal for cool 15c - or warm 15c, or typical water cooling route).

adam you no my feelings on dummy loads by now

as a bencher i am only intrested in cpu overclock

dummy heat loads mean nothing to me

i only want to know how fast i can make the cpu work


Out of interest can you tell me the heat load that would be needed to be applied to this unit

To simulate

6800 over clocked to 4500mhz @ 1,7v Also at 4600mhz and then at 4700mhz

Running a bench mark prog

and at what point the unit would fail to hold load

[n00b 0f l337]

I'm not sure which is why I wish you had a load tester :P
jk
Dun worry about it maybe someone will chime in.

[Pete]

225W at a guess Baz

Thats round 150-160 watts on my load tester. What you mean point fail to hold? If it fails its no good

Ontopic: More than 4-5 degrees subcooling will not give you better temps.

Edit: if you mean 1,7 vcore on bios, it will be more like 130-140 watts due to droop

[X_Man]

BAZX - Can I substitute that water thingee with this?

[TopherTony]

That would work in place of his waterbarrel. Difference being his semi passive cooling vs. your active cooling

[Jack]

Well I don't know... How many Watts can that Thermaltake unit handle? It doesn't look that powerfull.

[[XC] gomeler]

Just took a look at that TT radiator, it's positively huge and I imagine it would work. I'm really interested in seeing exactly how many 120mm x 120mm rads it takes to keep the temps under control.

[kayl]

nice work there bazx, some cold numbers there with the water cooling.
not so good 32m spi run though?

hehe i was waiting for that

this is just a load test not benching

looks good

[Pete]

This could be good in a Lian-Li V2k, PA120.2 or 120.3 mounted the roof!

Ssilencer managed to put a condensor as well as a radiator in a V2k case, so you should be able to put a decently sized radiator in the bottom of that case as well.
