I keep on having to open the case on the ones that get fans, because of all the dust accumulation. I'm just not willing to use hot drives, I have this strong suspicion that, cooling or not, they are not as reliable. BTW, if you think maintaining cooling is as simple as placing an extra fan in, well, it's not. You have to very carefully consider air flow, and your heat sources. It's not enough just to push a lot of air. If I was doing it for a lot of PCs, for a company (and I had a number of probes to make certain) then you can do a good job, but most of the fan placements I've seen, even many of those done by big companies, are a joke, done on the same level as putting in flashy displays on a stereo (it makes the buyer feel good without improving performance). ---------------------------------------------------------------------------- Chuck Robey | Interests include C & Java programming, FreeBSD, chuckr@picnic.mat.net | electronics, communications, and signal processing.
