Re: [EVDL] Zilla Engine Light Blinking - cooling things in general

This article discusses 'ionic air movement' to cool 'test' computer chips
from 140F to 95F.
http://www.extremetech.com/article2/0,1558,2170692,00.asp?kc=ETRSS02129TX1K0000532

This old article about "coolchips" (2003) is interesting:
http://www.smalltimes.com/Articles/Article_Display.cfm?ARTICLE_ID=269175&p=109

I'm still waiting on a chip or 2 to replace compressors
http://www.coolchips.gi/about.shtml

According to the licensing agreement, one would hope that Otmar would be
able to grap this one...
electrically cooling his zillas, *internally* would be even more efficient
than having to route everything to a common heat-sink...

I've heard about 'coolchips' for a while, but I've not seen any actual,
purchasable product.
Has anyone heard anything substantial? or is this still just so much
marketing wind?

This technology could be used anywhere from cpu, controller, refrigerator
items, to shoes on a hot day...

I am using a Maxi-Jet 1200 MarineLand pump which Otmar said works good. It

may be a little more then 1 gallon per minute. Also the pump is at a
high
point in the installation, so the head pressure is not that great if you
was
to pump upward.
