Personally, I have been working on cooling an identical version of the HP server found upstairs. <div><br></div><div>Pretty much any type of oil will work for coolant (white oil/mineral oil, veggie oil, motor oil, etc...) You are looking for a low viscosity liquid which is non-conductive and non-corrosive. I prefer liquids which do not have horrible MSDS sheets. All you need is a radiator, pump, and a holding/submersion tank. One can find integrated pumps and radiators cheaply on Ebay. </div><div><br></div><div>Lesson's learned: </div><div>A 6 gallon tank will not hold a 2U rack server. </div><div>Do not place non-SSD and/or optical drives into the coolant due to friction and design issues with the drives. </div><div>Be careful of wicking. Given time, coolant will find a way out of the case.</div><div>Places will laugh and think you are crazy for ordering 6 gallons of mineral oil. Be prepared to hunt for mineral oil or shell out a chunk of change for shipping/handling.</div><div><br></div><div><div><br></div><div>John Menerick</div><div>irc: liquidsun<br><div><br></div><div><br></div><div><br><div><div>On Jun 5, 2009, at 11:49 AM, Christie Dudley wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite">I heard talk of it being donated this weekend.
