Many are long overdue for [this time Really] an upgrade to vastly more efficient ones; efficiency which translates into a payback of purchase cost + interest - in 3-4 years. (In my case a few years ago - broke even in about 2.5 yrs. That Amana was a Dog..) And: costs a body ~$35 (typ) to haul one away / reclaim the Freon before it joins the megatons of other crap we throw away daily. Tell 'em they can use that thing - and get quiet as a bonus.. ('Course while its running it's Still an energy hog and later on.. you have to sell them the dehumidifier anti-condensation module, etc.) But they gets to Do It Theyself with simple instructions! See - Truth in Advertising IS our motto - it's just not honored, 'cept in those aberrant cases. Yeah.. nice links. Love the mini-reefer one. Pity that, while the component could be rather cheap if mass produced: this is probably one Expensive box. They also mentioned 'quiet'. I note they also have to add heaters against condensation. Still, if not going for -40 C temps, and in normal to lo-humidity areas: why not a simple circ water (OK deionized) system, with cooling utilizing nominal fan airflow - over usual evaporative cooler ("Swamp Coolers" as used here a lot - esp. in 'mobile homes'). Just stick-on an exchanger over CPU, video, memory (!?), with diff. sized tubes off a parallel manifold, to fine tune the BTU/hour needs. Quiet small pump. Large fan (slo = quieter) for the convection cooling (and to run swamp cooler). No expensive pieces at all, save maybe the exchangers - as these have to physically mount, somewhat neatly. Those must already be available at mass-produced rates. The Israelis made a tiny-box swamp cooler (bought one a few yrs. ago). It won't "cool a small room" particularly - but it blows adequately cool air on your face / chest! Very nicely engineered and built. (This alone wouldn't do, of course - humidity on output might be under 90% inside a \ufffd-box, but.. who wants to test those "rated RH" numbers even at 12 V max?) Guess I'd rather give a Dk place a boost over most others, as you say. (Been to Tivoli yet?) Test: what mean? when you hear somebody hawking, outside a tent: Loppe.. loppe.. loppe.. loppe..! :-\ufffd

RADBOX!"] And, finally, their overall [link\|http://www.overclockers.com/topiclist/index31.asp#WATER COOLING\|"WATER COOLING" Do-It-Yourself tips list]. But, yeah, I've been thinking for a while on a combination of the "Extreme Water-Cooling" guy's and the "RADBOX!" guys' approaches: The box you have at a distance is not just a simple cooler, but an evaporative-refrigeration rig; you pipe supercooled (i.e, just above freezing -- ~+4 C? -- in order to avoid condensation problems) water (or perhaps better yet, some form of alcohol; isopropanol is the usual suspect, I think) in to your computer where you work. Hey, why not put the power supply in that box, too, and pipe in the low-voltage stuff your box needs to run, in stead of 240 (or 120, as the case may be) heat-generating volts, while you're at it? With this approach, you can use a big old fridge, and it doesn't necessarily have to be one of those weird but oh-so-silent gas-burning coolth-through-heat ones, either. With a big fridge, you can get lots of cooling fluid, so you can cool your chipset and graphics adapter and hard drive, and, hey, why not your memory too -- so you ought to be able to eliminate pretty much ALL those pesky little fans. (If not, then dammit, pipe in (cooled!) air from the same box, too! :-) BTW, that's not the only amateur watercooling site out there -- it's a whole sub-culture. It intersects pretty closely with that of the overclockers (judging from the name, this site probably more properly belongs in that camp), and more loosely with that of the "Case Modders" in general -- if you want more links, let me know and I'll rummage around a bit for ya! Lastly: "Flea Circus", perhaps? (At least in Swedish, 'loppa' means 'flea'; and 'loppe' is close enough, at least for Scandinavian inter-government work... :-) Christian R.

What stops me from experimenting much is - while I have enough test equipment around, not a passel of accurate temp monitors (which I think is only sane way to vet some mod). Another time-sink :( Wouldn't have taken much for mfgs. to mount most fans w/ elastomers by now - lots of the sound energy is screwed directly to the case! I'll play a bit with my junk-box of Si-rubber pieces and such. Hmmm - mount with 4 dabs of RTV (room-temp vulcanizing stuff) Fans are light. Thanks for the intro to the Quiet Kewl Ones.. Ashton (Still, for an ex-Citr\ufffden type - all that hydraulics ... )
