Yes, the fan must draw a few hundred mW ... Looks like I should get one when I upgrade to a machine with SATA. (My newest machine is seven years old.

Hmm ... there is an old mercury barometer (was my grandfather's) in the hall -- that has a thermometer that reads in def F -- but I think I'll leave it in the hall where it can look pretty and where any mercury vapour that may possibly emanate from it has a relatively easy escape route (my study relies on a Velux skylight). > Sorry, I forgot it was a 'Ready Made' NAS box.

I have quite a few Seagate drives but this is the only Chinese one, and so far the Thai and Singaporean drives have been no trouble. Still: quite a lot of failures for Odie still represents a pretty small percentage of drives failing in use -- it's just that Odie usually only gets to see them when they do go. > I fell in love with Samsung's Spinpoint drives a few years back when I > discovered the joy of a silence (and low temperature operation) that > initially marked them out from the competition at that time. This Seagate is very quiet, more so than the Samsung. OTOH the Samsung in the PC I'm using (which is a different model -- an HD501LJ, rather than an HD502LJ) makes no noticeable noise (from within an Icy-Box trayless SATA enclosure inside an Antec Solo). Cheers, Daniel.

At bit OT, but I got myself one of those IR spot thermometers a while back when I started out building my own PBX/NAS/Router boxes just to make sure that inside their fanless environment nothing was getting too hot - since then I've used it on all sort of things...

Yes, they do, but I was running with the lids on, then removing it and measuring immediately to try to get worst-case values. Maybe not that scientific, but it seemed to satisfy me :) I'm currently frowning over a new box with 2 x 1TB WDC "Green" drives which are running at 50C surface temp (52 according to smartctl) which is annoying as I think I'm going to have to re-position them. Maybe I'd have been better off without it! Gordon |
