Water cooling maths?

[Greebe]

lenl,

of which a 50 to75 watt pump should do easily.

Now that's an understatement!

The 96gph/1.6gpm (363lph/6lpm) pump I have only draws 12.5 watts at 120vac.

Forget THG (LOL) as a resource for water cooling... many of us here have much more experience with these things than most anyother site on the web.

Well there you go, when I said It could do it easily I really meant it! It was a quick off the cuff guestimate, I havent really had to source a pump that small yet but I have ran across a few posts showing the procedures. Looks quite neat. I havent got that kind of cpu horse power to worry about to much heat just yet! Still running a Tbird 600.

Thanks

Does anyone know how many watts a XP/MP 1800+ - 2000+ produces? I have looked on AMD's site, but I cant seem to find it...

Perhaps I should get friendly my my insurrance company in anticipation???

Cheers all....

XP 2000+ produces 70watts peak... let me lookup the XP1800+ specs...

Radiator size and design also greatly effects getting rid the dreaded heat build up... aluminum thin fin designs (your typical auto oil cooler) aren't as good as they first appear, but they're cheap ($). Auto heater cores are much better typically cause they're made from copper.

With my setup the objective went for lowest cost (bang for the buck), lower the sound level and utilizing as much materials I had on hand. Which is what mine does very well. Remember I'm running an Athlon500@850 (producing 85.4watts peak!), it's thermal headroom is extremely limited. Thus if room ambient temps prior to water cooling exceeded 77f (25c) it would crap out if really stressed (ie gaming Rendering 3D, converting vid files, etc). Now I have an additional 7c of room ambient temperature headroom, which suits me fine, especially here in Hot/sunny Florida!

Have you tried the minifridge (or maybe minifreezer) solution yet? Just run all that crap into the little fridge (get a used one for $20 or so) and lower effective ambient temp to 40 degrees farenheit. Any fans you put against the fins are inside an insulated cabinet too, and are much more silent (though you still have he refridgerator motor noise to deal with, but stick it in a closet.)

If and when I build a house, I'm going to have an insulated closet with a rack in it for my system, with a window unit air conditioner blasting into it at the bottom, and a return air for the central hvac in the ceiling. All I would have on the desk would be a little scsi case for cd/dvd drives, with power and data lines run in from the closet. Then I can have it dead silent in the room and listen to music and such.. even quieter passages of Sibelius symphonies would be untarnished by fan noise.

Using a seperate AC unit is fine, but the 12vdc converted mini refridgerators typically used in RV's that I've seen setup to chill a cpu aren't up to the task... at best they can handle the cpu only... not the heat of an entire system which today equals or exceeds 300watts.

The problem I would have with doing this is it's humid here... when opening up the fridge to service the computer (changing CD's, testing, Floppy's would hate this!!!) condensation would build up fast and cause all kinds of other problems.

Think you're looking for something like a VapoChill setup Chuck.

[Novdid]

AAAHHH, Vapochill, DROOL, a geeks dream...

[Fat Tone]

You guys! You da men!

Thanks for all the info. All good stuff. I think the only thing missing (and likely to remain so) is the actual specs on the available blocks & rads, but we have enough info to build a system that should have plenty of head room! Thanks again.

Now if only someone out there knew as much about the Netport Express XL printserver...

Rubank, us hicks here in the UK interpret digial photography as making a peephole camera and only using one crayon to colour it in.

Novdid, when Number One Son was a few months old, I took a photo of his face and grey-embossed it (to nearly flat) to use as a tiled background on a family web page. I shrank that and used it as an avatar here. Unfortunately, when we were messing with, erm ,ahem, *someones* identity around here, I changed my avatar temporarily, but lost some of the colour depth in the process, so its not so clear anymore. Guess I deserved it for being a bad boy. I think we all understand yours

That Vapochill system is sweet, but just didn't give me that mad-scientist rush that this article did

I know I must have originally gotten this link here somewhere..

Here's the setup I remembered seeing:

Sacrilege - surely chilling the BEER is more important?

[Novdid]

I agree!

[Greebe]

Think I'd want a bigger fridge for my beer

Chuck, looks nice (I remember seeing this once upon a time), but a shame that they don't have anything but passive airflow to chill those coils. They should have used a coupled anti freze mixture or silicone oil submerging the cold plate (freezer shelf) and coils from that into the water storage reservior. Would have been a much more effecient way to go.

I can actually see your boy on the pic now, Tony.
