One other thing, a squirrel cage blower will force more of its rating into a restricted box than will a fan bladed blower. The fan type will have 'blow back/around/whatever' the blades where as a squirrel cage ones will attempt to force as much of their rating as possible out their output port. Both suck at sucking air thru their intakes, so never put the intake against a hole in the box as the thru put will drop.<br><br>I strongly suspect that is why swamp coolers use a squirrel cage instead of a bladed fan...besides the bladed would be bigger for the same unrestricted flow air out put.<br><br>Cpu bladed coolers are chosen for space considerations, not over all efficiency. That is why they use them, they are shallow thickness wise. and 'space efficient<br><br><b><i>KE7FEG &lt;eculbert@yahoo.com&gt;</i></b> wrote:<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"> 1500 cfm thru the case? that is almost 1/2 the
 volume of air of a small swamp cooler. The case is too small and doesn't have that much opening. realisticly about 300 or so cfm would be massive air movement thru there.<br><br>I have ordered one item from the following site w/satisfaction.

He experience no heat problem. I am reasonably sure the heat problem may turn out to be a ps problem when it fails. Or the cpu cooler is marginal. A well designed system  should survive swamp cooler life. Yes, I know
 it can get to close to 90 and humid, but humid air cools better.<br><br>An example that vividly points out humid vs dry was the 62 ford falcon we had when we came out here.

All the other  higher volume either don't have a picture to

Or cost about $2500 or so to get aps or salt river to run a 3 phase line in. Of course you could get an phase inverter for $100-200 and get the same thing off of the 2 phase 220 volt line.<br><br><br><br><b><i>JD Austin &lt;jd@twingeckos.com&gt;</i></b> wrote:<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"> You have a few options:<br>Go crazy with fans inside the case.<br>Use electric chillers (peltiers?)<br>Take the cover off and put an external fan on it.<br><br>When I lived in the same conditions I did #3 :).<br>jd<br><br>-----Original Message-----<br>From: "Technomage" <technomage-hawke@cox.net><br>To: plug-discuss@lists.plug.phoenix.az.us<br>Sent: 8/9/06 7:54 AM<br>Subject: funneling heat away from the inside of a  box<br><br>ok,<br>I am having some serious
