(fwd) References: Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Not so fast there, I built an Alpha system the other week and the CPU ran DARN hot, I asked the vendor and I casually mentioned that it should not be a problem because "The cover was off the whole time" - he said I should never run my system for any length of time with the cover off, because the air is not flowing, it is stagnant over the CPU. I suspect that even though you have a fan next to the CPU, the heat is not being pulled away from the processor by the PS fan as it would if the case were closed, you simply have the fan blowing air onto the CPU and hopefully "pushing" the hot air away. I would not point my finger at a heat issue right away, but I would not dismiss it so quickly either (BTW, after I closed the case the Alpha system ran fine for 72 hours straight, with the case open it started to fail after about 8 hours or so...
