Project Mega Chill

[Karlmcwade]

Im making a water cooled p.c atm, Nothing new them i hear you say. My water cooled rig is being made for performance not to make is silent. My componets list is as follows.
1 7000lpm industrial water pump (136 litres per min)
2 Home made water bock made from Alloy with fittings to take 28mm copper pipeing. (have to use alloy as copper is to hard for me to machine with my dremill)
3 100 litre water res
3 A lorry Rad (yes i said lorry it huge)
4 All my pipeing will be 28mm copper no tubing at all as the pressure might burst the piping ( nothing worse than a wet p.c )
5 panfice aux fan 3375 cfm

Maybe cool the north bridge with a smaller w/b and 15mm fittings (again home made)

Going to use zinc as a sacrefice item in the res so that the copper does not corrode the alloy and distill the water or maybe just use all window wiper fluid (methonal)

Any ideas or thoughts plz post ( and yes i cannot spell were's the F7 key when u need it )

What kind of furnace will it be cooling?

My current rig with some new mem Kingston hyper x 2*256 Pc3200
Gonna push it to 2600mhz or killit trying
My Air cooling setup is v noisey(2 delta 120mmfans 54 db each ( very loud), 4 other 80mm fans oem

That's serious overkill!

Cool, none the less. With that much coolant and that big of a radiator I think you wont have much to worry about, and I wouldn't even bother running 3375CFM through it.

Now if you had the urge, putting a 500W TEC (peltier) on it (do they even come that big), that setup would be awesome!

[Groth]

What kind of pump is that? What's the max head/pressure? Power draw?

[Whodovoodoo2man]

Absolute madness!

If you can't dremel copper block, make it out of copper sheet. A lot cheaper, and every bit as effective- it's the water that cools.

Don,t like tec,s there price vs performance is not worth the effort, (really i cannot afford one).

As for the pump spec's Groth its 7000lmp with a 6m head @ 30mm (410w) It mains powered so a modded power supply which will turn it on along with the p.c so no fryed cpu (hopefully)

Have to use alloy as copper is very hard to get hold of here in N.Ireland (In block form anyway, I think Companies think im making a bomb or somthing :shrug: ) Alloy is cheap and readlly avalible and this rig cost no more than £100.

The pump was the most expencive part at £57 ( I work for a hardware store so staff discount helps keep the cost down)

[Karlmcwade]

And i tinks that this will rival vapo's /prommie's as it is all ready.
Tec would be over kill ( if this is not all ready)

6 meters of head? That's not much for 410 watts. Once you put a block on there, I'll be shocked it you can get more than 40-50 l/min throughput.

Not using 6m of head tho it going to run horizontly so no head losses. Its rated at 7000lpm With a 6m head @ 30mm diamater So i will get at least 130 lpm, even with a block and rad Its a very strong pump (Loads of torque) 1 hp

[Groth]

Horizontal or vertical or whatever for your pipe runs makes no difference. Running water through an obstruction (like a water block) results in a head loss (pressure drop) across the obstruction. I'm predicting based on some of BillA's pressure/flow data that with only 6 m of head to work with, you won't push more than 50 l/min through even an unrestrictive block.

More details on pump would be good. A link to it's specifications would be better. An actual P-Q curve would be best.

This pump is designed to pump water from a depth of 6 meters straight up(swimming pool) which means it has to force water up a 30mm pipe 6m high And the pumps power is 7000lmh after it has cleared the pipe so it is pumping faster than 7000lph and is loosing power so that when it gets to 6 meters it is flowing 7000lph Which is a hell of a lot Nearly 6x more than a 1250 And it is designed to move Solids ie dirt rocks up to a size of 3 cm3 (any bigger will no get threw the Grill) so i dont think that a water block will really slow it down seing the block i am making is made for Little restance for flow (hoping that the Liquid temp will be so low that i will not need a High flow restance block) I will only have 3 m of coper tubing in total (excluding the rad) and this is 28mm so 2 mm less that what the pump is rated to pump so It should in thery pump slightly faster.

[Groth]

At various points you described the pump as "7000lpm", "136 litres per min", "7000lmp", "7000lmh", and "7000lph", and as both 410 W and 1 hp (1 hosepower = 746 W). Makes it tough to know what expect results-wise. So, back to my first questions: What kind of pump is that? What's the max head/pressure?

I'm a big fan of overkill, but you have to have realistic expectations. Saying "And i tinks that this will rival vapo's /prommie's as it is all ready" is setting yourself up for serious disappointment.

[siavash_s_s]

uhh i dont understand how this is going to be anny better then a normal setup? the water will *always* be the same or higher than the ambient, so why the big setup? the only reason i would do this is to cool an entire pc room or cafe or lab, then it would be good
but for 1 cpu you are going to get around ambient and no better, which is similar to a normal setup anyway. as said before a tec would be a viable option here

[Sandman001]

Seems extreme overkill......pointless overkill.........especially with a homemade block that won't be a top performer (my geuss).

the big rad is wasted if you aren't using TEC's or something.

[siavash_s_s]

this seems to me to be a more *make my penis bigger than do something usefull* project lol

your wasting time money electricity lol with this unless you hook it up to a whole lab full of pc's, now that would b awsome, blue reactive liquid in tubes everywhere

get a tec for it, OR you could make an outdoor bong and use it to cool your room and possibly your drink too LOL

[Skulemate]

Groth is right... pump specs would be lovely. In all likelihood this pump is totally inappropriate, as your cooling loop will be cooling the pump first and the CPU second. Remember, regardless of how big your radiator is you can only approach (and never reach) ambient temperatures with a pure water-cooling setup... you won't likely be close to a Vapochill or Prometia.

he probably wont ever go much over ambient tho (i may be wrong...)
but i still dont get it :shrug: :shrug: :shrug:

[Groth]

I'm just hoping we haven't completely scared 'im off...I want to see pics of the rad and fan.

yeh lol dont be shy, we still have the *real* flamers in the car LOL

show us your setup, then sell it to a computer lab
turn a profit even

Amazing that there is discussion of TEC's/Vapo's being too expensive, yet by the sound of the size of the pump/fan, the running costs of this beast will be well over $100/month just in electricity alone.

When going for overkill, one must always keep an eye on that electricity bill, because electricity isn't free/cheap when you start talking about sucking down what seems to me to be >1KWh full-time.

Methinks in 6 months a Vapo could easily be paid for.

Oh, and 7000LPH at 6m head doesn't sound that impressive to me. Give me 1000LPH at 20m head any day.

Could not afford that pump Cathar.
Update on rig is as follows Going to get a tec now u lot have convinced me
Yes this rig will suck in a lot of power and it doesnt really bother me as it is going on display in a computer shop as a show peice. I not posting pic's untill its fully finished. Its a mess atm. but it passed the leak test At full steam and no leaks the pump is very noisy,
