Presumably this is not very good for the CPU. What, specifically, is your objective? I'm gathering you're looking for a quiet processor by removing the fan. What processor speed do you need? I run a PPro 180 which has no CPU fan, just a moderately large heatsink. Since 1997. If you can use an actively cooled system elsewhere, a low-end Pentium system or 486 with scads o' RAM, a good video card, and a fast NIC, makes a good X terminal. Can additional, silent, cooling be applied? There are both solid-state and liquid cooling systems which may be appropriate -- the key to silent cooling is to dissipate the heat quickly and to a large surface area. Another tack is to use non-Intel hardware. The PowerPC (Macintosh), ARM, and MIPS chips all run significantly cooler than x86. The original Cobalt Cube has minimal cooling, though the current version is based on x86 and has a larger fan. Likewise the Netwinder. Note that both are very underpowered by current standards -- sufficient for file/print serving, but slow for much else. Likewise the Mac Cube is a passively Still another tack might be to find a very quiet fan. I don't have specifics on any of this, but suspect an isolation mounting system, large radius, low speed, and well-engineered bearings, will help -- Karsten M.
