You are getting good components, it seems, but to choke such an expensive system with so little memory is a crime. I usually run 2-3GB memory on my MySQL servers (older dual Xeons). Then again, I have some big databases. Also, if you are running RAID 5, you should buy an extra drive for a spare. The...

Try svc or sidewinder computers (recommended). There are many others. Try to get ones with the three-wire connections so that you can monitor the fan RPMs, and make sure they are L1A models (low speed). You can volt them down if you want with resistors, diodes or a simple fan controller (like the Za...

Before you run out and spend money, I'd suggest that you do some careful temperature monitoring of your CPUs. You can probably reduce the voltage on your CPU fans to reduce the noise. You could also replace their fans with Panaflos, if you want. I would also listen carefully to locate the worst soun...

You are most welcomed! The slot 1 computers were designed in an era where silent computing was just not important. The irony is that they did not suck much juice, and really did not need a lot of air flow to keep them cool. If you have a decent heat sink on the CPU -- and it does not have to be wond...

I thought I would give you a quick update on making Hoover -- the loudest computer I have ever heard -- not so loud. What I did was not too exotic, but it worked really, really well. I cut out the restrictive inlet and outlet grills in the power supply, and replaced the fan with a Panaflo L1A. I cut...

Just to echo what Mr Oblivious said, it seems P3 boards with ISA slots aren't completely unavailable. I have a P3 1 GHz at home on this board: http://www.shentech.com/sy7vba133u.html (who buys these for $85?), but I don't use the ISA slots.

The digital thermometer is a reasonable idea. Any idea what they cost? I paid about $10 for mine at target, but you can get ones designed to fit 3.5" or 5.25" bays if you want something nicer looking. OK, that's fine. I will look for a cheapie.

Considering the maximum safe temp for a p3, the original intended use of the machine, the 80cfm fan, the fans on the heatsink (I've got 2 passively cooled p3's of that speed or faster) and the fact the cpus are in an air duct, I think it's quite safe to say the cooling on that machine is complete o...

Reducing Noise from the Hoover -- a Dual PIII
I just acquired an old HP Netserver E60, which is a dual PIII/SCSI machine. I got it because it has an ISA slot in addition to the PCIs of the era, and I need the ISA slot for an instrument controller, and the software runs only on NT 4. Ugh. In any event, it is the loudest computer I have ever hear...

Thanks for the reply. It is a shame that Aerocool did not go to the effort to shave off those few mm. It seems like a waste to get so close, and mess it up with something that is so easy to correct.

I have noted that the Aerocool VM-101 also takes a single slot (namely, it does not occupy the neighboring one). There have been some discussions of this one in the forums, but it seems basically to be the same idea as those from Aerocase. I'll have to check to see if it would fit. Are there any oth...

Single-slot VGA cooler?
My dual CPU/SCSI system is now pretty quiet other than the obnoxious cooling fan on my graphics card (nVidia Quadro FX1000). It looks like the only single-slot options to reduce the noise from the graphics card are those from Aerocase. Is that right? If so, I will ask them about what is needed for m...

I'm looking for a "quiet" 50mm x 50mm x 10mm fan with roughly 9 cfm of air flow. No, none of these is truly quiet, but that is the only size that will work for me. So please do not suggest using a large or thicker one. (This is for an old Sun Ultra 1E clone). I've come across the Evercool line, and ...

Bat, I've given no thought to oxygen "scavanging," though redox reagents would work. Choose the redox potential carefully -- I wouldn't think that you'd want to precipitate metals (some of which will dissolve, albeit not much) somewhere in the system. I don't recall what we added for larger systems ...

Let me address the question that started this thread. You have two basic choices to get drivers that will work for you: the (old) open-source ones, and nVidia's binary ones. What you choose will largely be a function of what you want to do with your computer. If you need fast 3D for games or solids ...

I'm no XFree fanboy, but it is quite easy to have both monitors use hardware acceleration in XFree. You can run dual independent X sessions (one on each monitor), or MergedFB (a Xinerama-like mode that uses a single frame buffer); both will give full acceleration if you have the DRI extensions set u...

I went through the same question when I set up my dual-monitor FreeBSD system. What you have to answer is "what do you want to use your computer for?"

I don't quite understand your questions, so let me talk around them to see if I hit on something that makes sense. In the researator, as I understand it (and bear in mind I've not seen one) you have a tube that is partially (half? two-thirds? a bit more?) filled with water. A pump draws it out of th...

Having a vent hole would seem to make the unit much more convenient to use and maintain. You don't have to "burp" it (like you do a car system), you can remove the top while it is running to add or remove coolant as you like (to measure the conductivity, pH or bacterial load, for example) or measure...

Does the Reserator have a vent hole? Probably a good idea, and again, not a big deal as long as the coolant has decent basic properties and the coolant is replaced once in a while.

If you mean that you pick up a bit of carbon dioxide when you transfer it from container to the system, sure. Shouldn't make much difference.

Actually I don't think it will make much of a difference which type of water you use. As long as hardness is removed (namely, Ca, Mg, Mn and Fe) I doubt you would see any difference, particularly once antifreeze, anti-bacterials and anti-corrosives are added. FWIW, DI water is usually produced by me...
