This person is correct. Yay.. Intelligence.
Poorly built kit? I hope you are not referring to my attempt to build said system. I've been in the HVAC business for half my life. If you think you know more about heating & cooling then I, I will gladly debate you. Flames aren't appreciated nor will be answered.
Are any of you aware of how much a centrail air-conditioner unit for your house costs a contractor? between $700-$1100 depending on house size. Most houses fall in the $800-900 range.
For a company to charge you $500 for a Tiny unit to cool your CPU is laughable. The markup is huge because not to many people are familliar with HVAC nor do they have easy access to the parts needed.
I can provide links to these prices but you would need a business license to purchase any units at these prices. Thats how they get away with charging 2,000$-4,000$ for an AC unit that costs them $900.
Thats HVAC business, it's very profitable if you can afford initial startup which includes being licensed and bonded in every city you work, insured, and advertisement. Not to mention tools and employee's. It costs around $20k minimum to start your own HVAC business. That is why I am no longer in the field. My dad had his own business so he still has his accounts with various wholesalers, but is retired so I no longer do HVAC.
I'm a lowly technician for verizon wireless now...
As far as phase change cooling goes, most of you have it all wrong. Except for the poster above. Phase change cooling will be useless soon anyways as the chips get smaller and run at lower and lower temps. Negative side effects include less voltage tolerance due to die size, electron mitigation etc... But the smaller they make the chip, the less heat becomes the issue.
