I have a few DEC RZ26's and RZ28's (1 & 2 GB SCSI) here that, without enough air flow across them, get hot enough to actually create blisters. (Usually on my right index finger.) Discovered that I can strap an old 486 heatsink/fan to the top of them, and that REALLY helps cool them down. Just have to grind off the little "lips" that drop down over the sides of the CPU so that you get full-surface contact of the heat sink. mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
