Advice on Fanless PC
Hi,
I'm trying to assemble a PC with moderate-to-low computing power, hoping that I will be able to get something with as close to ZERO dB of noise as possible. I thought the Atom processors were designed to use no fan, but the available MB/CPU combos I've seen sport a big heat sink with fan. I wonder if I could downclock to a point where I can simply remove the fan with no risk to fry the CPU? (actually, would that be the case with a regular intel or AMD processor?) Any other advice not involving those 3 kg fanless heat sinks? (yeah, yeah, I'm going with the hyperbole :-) ) Carlos -- |

And the Nano should be competitive in performance against Atom. New Shuttle PC has Via Nano, fanless cooling - The Tech Report http://techreport.com/discussions.x/16985 Yousuf Khan |

Advice on Fanless PC
Yousuf Khan dachte sehr stark über folgendes nach :
snip VIA Nano can be fanless, I believe. And the Nano should be competitive in performance against Atom. New Shuttle PC has Via Nano, fanless cooling - The Tech Report http://techreport.com/discussions.x/16985 Yousuf Khan The downside of Shuttle's offerings is that these things aren't upgradeable. Several years back (in a time when the average off-the-shelf PC made your ears bleed after a while) - I bought a Pentium M based Shuttle barebone. Back then, I thought I would never want to upgrade the 1,5 GHz CPU, but now I regret buying it instead of a standard (micro)ATX case, especially when running Java IDEs like Eclipse or Netbeans. -- O. |

I wonder if I could downclock to a point where I can simply remove the fan with no risk to fry the CPU? (actually, would that be the case with a regular intel or AMD processor?) I have a regular AMD Athlon(tm) X2 Dual Core BE-2400, on a Gigabyte MicroATX motherboard with the AMD 780G chipset. This is one of their low- power 45W processors, runs at 2.2ghz max. It is really energy-sipping... idles around 21°C with a poorly-attached stock heatsink (no thermal paste) and stock fan in a small case with two hard drives sitting at around 40°C. No case fan, either. I've considered running it fanless, but didn't bother because most of the time, the fan is running so slow as to be inaudible. But I wouldn't hesitate to try it fanless, either. AMD has made a whole series of these low-power dual-core processors (http://en.wikipedia.org/wiki/ List_of_AMD_Athlon_X2_microprocessors#.22Brisbane. 22_.28G1_.26_G2.2C_65_nm.29) and you can get a single-core Sempron version for about $40 (http:// http://www.newegg.com/Product/Produc...2E16819103698). Although I only paid about $45 for mine on sale! Tom's hardware found that these things use 7-10W when idling, and stay under 45W when maxed out (http://www.tomshardware.com/reviews/amd-power- cpu,1925-7.html). So, I think it's quite possible to use a cheap low- power AMD processor and go fanless. Any other advice not involving those 3 kg fanless heat sinks? (yeah, yeah, I'm going with the hyperbole :-) ) If you really don't care about performance at all, Atom or VIA are good choices, as previously suggested. But those are a lot more performance- and upgrade-limited than a "real" socketed desktop processor. Dan |
