question about no rad

[siavash_s_s]

im just thinkng, it would b very convenient for me to have no radiator and just a tank of water with a sub merged pump in it. im thinking a closed res about 20x16x44 cm dimensions made of either plexiglass or copper sheet

i just want to know if this is going to stay any where near ambient, it is a lot of water but im just not too sure atm

Have a look at Bladerunner's site (zerofanzone google it and you should find it)

So it IS possible though I don't know what size you will need for an ambient system - I'm thinking that might not be enough, though.

Think of it as a kettle the heating element boiling the water there is a point where a heating source of X watts can no longer raise the temperature of the water because the heat is disapated before it has a chance to rise in temperature.

Radiators work buy giving the water more surface area so what you are etentially talking about is a VERY INEFFICIENT passive radiator of 200x160x440 dimentions. From that you can even work out the surface area on a compared to a heatcore I'm thinking they will be pretty low.

Add that to the fact there will be less airflow THROUGH the core of your "radiator" so it will be even less effective.

But it IS possible but I think you will need to go a lot larger than that - or find a way to cool/exchange the water.

i understand all that, what im really looking for is a past experience... its just that making a plexi block is easier then one with places for water res, rad, fan piping wiring etc..
its a pain in the ass with a rad
lol
thnx but

[siavash_s_s]

sweet jeesus his setup is nice
if only i had a mill id take that setup on.. and BEAT ITT MAWIAHAAHAHAHAAUHAHAHA

I don't suggest it, the real cooling in a water cooling system is the radiator, however if the water tank is big enough and has enough surface area, if you don't go OC too much you might be able to run at stock speeds. It depends how you set up the WC system. That res would be a bit small for this.

You could make a res out of copper and have it act like a HUGE heatsink, with fins or have one that acts like a radiator, but at one point for that you would need airflow too...

I would just get a big resovoir on top of or under your PC so it can be bigger...

The plexi block will rather act as an insulation then a dissipation of heat, I would use copper for this if you don't have a rad... still don't suggest it.

If you want a really rough idea of size for that res, I would say you need at least 1m2 of total surface area to get your water to within roughly 10°C of ambient. This is with just natural convection, with a typical CPU heatload. (back of an envelope style calculation, guessing h=5W/m2.K)

As Boli and Ewout_vB said, 20x16x44 cm is a bit on the small side. You'd be lucky to get to within 20°C of ambient. Theres nothing wrong with the idea though.

If I had an aquarium, I know what I'd do with it

How would a 40,000L rainwater tank go?

[siavash_s_s]

ahh its very annyoing how these damn chips are more like heaters then anytihng else
looks like im gunna have to stick with my rad...
thnx for posts evryone

bong is even more work man.. plus too much vapour in my room = me getting sticky and room gettin smelly

[j813]

ya but if ya would use a reservoir it would have that vapor thing.
lol, my room temp can get 33`C but even though I still use a bong. so dont get near me we're gettin sticky. lol

[siavash_s_s]

bong is a silly unpractical idea only used by extremists and *make doers*
the ideal situation is a full refrigerated case with refrigerant goint to cpu then to what ever then opening out and covering the whole mobo
im dreaming..

Geoffman:

If it was full, probably quite well - that much water would take a LONG time to heat up. However you might have issues with running the tank contents through your blocks (bio-growth, corrosion, etc.) so you might want some sort of water / water heat exchanger. Also, does the tank get solar gain? What is it's temp w/o PC cooling? If the tank was sitting in the sun long enough to heat up alot that might not be a good thing.

This MIGHT work, but it would have to be quite a bit bigger, AND copper NOT plexiglass. Conductive properties of plexiglass are crap, so you'd be looking at a hefty delta T associated simply with getting the thermal energy across the walls of the res.

u know what i found
i had an old old mini water heater for like an office, and inside is a pretty large copper ball thing. i goto open it up and remove the element and all the valves, then ill use that maybe
altho it is pretty big
