The problem with refrigeration used with computers is the condensation .

This all seems quite extreme, I'm sure you could just get away with just using dust filters on the fans and air inlets.

Or build a basic cabinet similar to Velocity3x's link.

Indeed, let's not forget this is the same room I sleep in, if I needed to go to the extreme of a cabinet then I probably shouldn't be doing so ;)

some people here are getting abit off topic with cooling when we should be talking about how to filter or stop dust destroying our computers, sorry if I annoyed some of you guys but cooling has nothing to do with keeping dust out and other crap, but you only need really good cooling if you playing HQ games on high and playing all day long or if your an over clocker.
Once again sorry if I annoyed anyone.

Velocity's idea is great and if your on a low budget building one wouldn't be hard, or you can put it in another room like what some people said.

abit off topic

I guess the link is that putting in filters or enclosing the case will reduce the effectiveness of the stock cooling. The cooling methods described were meant to eliminate airflow through the PC case avoiding dust getting in.

Refrigeration works fine with electronics... as long as you keep in on all the time. Condensation becomes an issue when you cycle the refrigeration and allow warm humid air in. We had more than a few jobs at the water purification company I worked at that equipped the electrical components panel boxes with refrigeration units not much different than a window unit!

I think Jack's post 3 above mine really brings the topic back to reality lol... If he's going to LIVE in the same room as the one he machines in, I would put priority on his own well being before a computer's. I've seen more than a few shop computers and they all seem to use a positive pressure design similar to a rack server. Just put a nice filter on the intake side and you should be good if your adamant about changing it/cleaning it on a monthly or so basis as needed.

Did I mention I love fans?

Added another transparenty lighty-upy one to the front covering three unused 5.25" bays :D quick paintjob and it doesn't look too shabby.

I want to modify one of those fans to strobe a high intensity LED to make the blade appear to be barely moving,

Tech - grab the signal from the Tach line output (typically the yellow wire) and plug that signal into a PIC that counts the pulses. For every 2 pulses (on most pc fans) that is one full rotation. You can then add a pot input to the PIC to vary the gain on the counting and you can then have your blades moving forward, back, or stationary.

Most of that you already probably knew - but it would be a fun day project!

why not have a cooler thats quiet? Image


Gents,

We were looking to cool water for another reason. Something about coloring aluminum. Anyway, I realized the aquarium hobbyists have chillers designed to cool fish tanks. These are refrigerated coolers, nicer ones have programmable stats on them. We found ours in Craigslist. A really elegant way to make chilled water for various uses.
