Alex<br>If you want to passive cool a cpu, you need a cpu that can be passively cooled. This is pretty much only specific low powered cpu's like VIAs, or laptop model cpus. However many value cpus can be cooled with a giant heatsink and a giant slow moving fan. The key is you only need SOME airflow, you don't need massive airflow if you have enough surface area.<br>Thermalright makes a few (massive) coolers that are meant to be run without a fan.<br>Just don't expect decent temps OR any overclocking.<br>Not worth it at all IMHO. - processors get as hot as how hard you make them work.....with a duo, you could slow down the clock<br>- underclock it (?), to reduce heat...<br>A good low RPM 120mm fan will do wonders for a decent heat sink [with good thermal paste on] and will make very very little noise. e.g.<br>http://www.scan.co.uk/Product.aspx?WebProductID=1040411&source=froogle<br>The only way you'd even hear it is if you had no other fans in your system.<br>The Core 2 Duo's work fine,(even moderately overclocked) with the Thermalright Ultra 120 extreme cooled passively. It does tend to get a little on the hot side, though it definitely won't fit a 1u case.<br>I don't know of a <u>cheap/small</u> passive for the Core 2 Duo.....<br><br>Aitch :)<br>==========================================<br><br><br>> To: kent@mailman.lug.org.uk<br>> From: alex@alexlayfield.force9.co.uk<br>> Date: Wed, 23 Sep 2009 13:37:35 +0000<br>> Subject: Re: [Klug-general] Custom ATX sized heatsink<br>> <br>> Hacksaws generally make things smaller in my experience :-)<br>> <br>> I should've explained what I am trying to do.<br>> <br>> Passive cooling of an ATX Core2Duo E5400 with G41 chipset & onboard GPU.<br>> <br>> E5400 = 65W max TPD<br>> <br>> PicoPSU 120W<br>> <br>> 2x 2.5" SATA HDDs<br>> <br>> Mobo TPD depends on what's being used.<br>> Intel DG41TY<br>> <br>> MTBF of components is rated @ 55degC so need to be within that bracket.<br>> <br>> Want case to be minimally sized (1U too) & incorporate heatsink.
