My friend just bought a Barton to use as a server in his home. I was surprised to find idle temps above 40 C. I think the max die temp is something like 55 C, but we don't want to go there. This is a Barton 2600, in an Asus A7N8X deluxe mobo, with the case off, until we finish configureing. I had told him to get a different HS/fan, but this was what was available... a Top Motor fan? Anyway, he will get something else, what temps (not overclocked) should we be OK with? My computer runs at 40 C most of the time, I can get it cooler by turning the fan up faster and louder, but I AM overclocked... He wants a QUIET cooler, his Antec case has a 92 MM fan out the back, thermostatically controlled. Would 45C under load be OK, or would that jeapordize his CPU life?
