This is a bit off topic, but I have commented on the issue of dusty heat syncs in the past. With the recent discussion of the high temps generated by the last V7-beta on some systems (not mine), I thought that I would remind folks. I just dusted out my 2.5 year old laptop (2 GHz Pentium-M) and the difference was impressive. (And so was the cloud of dust I blew out!) Quiescent temperature dropped from 60C to 53C and the peak temperature during a kernel build dropped from a very toasty 90C to a comfortable 72C. 18C (32F) is a huge improvement! The dust either a laptop or a tower can collect is impressive, even in a fairly clean environment. I suspect an annual cleaning of heat syncs could significantly increase both the reliability and lifetime of systems. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
