I have an old Dell Optiplex

I have an old Dell Optiplex GX150 (P3 coppermine @ 930Mhz) that I first used to join e@h and nearly fell off the chair when it told me it wanted around 23 hours to complete its first wu. Needless to say I set it to 'no new tasks' let it process and then detached from e@h. I now just use the Q6600's to process e@h.

The old GX150 is soon to be replaced by a GX270 (P4 @ 3Ghz with HT). I am hoping when boinc gets get their 'Super Host' idea off the ground it can be used for that.

If I understand this correctly, the "superhost" would mainly be a kind of "proxy/gateway" but not a "cruncher", I guess a PIII would be more than sufficient for that. Or am I missing something? To me a superhost is something that might be useful for large "farms" of crunchers?

You are correct, its basically just queuing the wu and results. Although I will have to put a larger hard disk in it (it only has a 10Gb HDD at the moment).

As I have a few Q6600's and a GX270 running I probably qualify as a 'farmer', although its a quite a small farm :-)

Speaking about P-IIIs again:

Speaking about P-IIIs again: I've got those Dual 1 height unit servers that are crunching just fine but making a hell of a noise, because of those tiny, high RPM fans are blowing air sideways thru the cooling ribs mounted on top of the CPUs.

Those PIIIs have a TDP of around 35 W only, so maybe there are less noisy solutions that would fit into the 1U box. (Drilling a hole in the top cover to blow air from above with a larger/slower fan is not an option for aesthetic reasons :-) ).

Anyway I suspect that those little fans will fail one after another after having been in operation for a couple of years already, so thinking about replacements is probably mandatory sooner or later.

Here is a massively off-topic request stimulated by your fan comments--I'll not object if it is moderated out of existence.

Our church owns a Dell 4100mp DLP projector. For some months it has tended to stop projecting with an overheat light coming on after 20 or 30 minutes of use.

Dell support says that most likely one of the two fans has failed. As it is out of warranty, the price for shipping and diagnosis would be $234.85, with actual repair parts extra when determined.

If I could get the thing apart far enough to get at the fans, I'm confident I could replace them. Does anyone seeing this have 4100mp dismantling advice? I've taken out all obviously relevant screws, but suspect there is a trick akin to "squeeze plastic bit A while pushing on plastic bit B" needed to get further.

Have you tried the Dell website to see if there's documentation for this item?

Yes, I did. They have the user manual in pdf, but the only dismantling supported is that required for a lamp change.

The loudest of those I could find at Nidec's web site was 36.7dB... You'd surely have a fit with my Panaflo fans, since I have 3 @ 32dB, 1 @ 38.2dB, and 1 @ 35.5dB... The flaw in my case is that it uses only 80mm fans. Next case I get is going to use 120mm...or larger...

Here's how my trusty Pentium

Here's how my trusty Pentium II-based Dell Poweredge is doing with the S5R3 workunits.

Yeah, talk about some blazing speed.
