Thanks. I don't think vertical suspension will work for me because I will need more drives than I can fit with a vertical orientation. I would be happy with a rubber grommet type of mounting - except the drive cage on that case doesn't have the extra width for them (just 1/8 of an inch!).

Hard drive noise in Antec 300?

I am thinking of buying an Antec 300 to use for my Windows Home Server system. It is inexpensive, has washable filters, and enough drive mounts. But the hard drive mounts are straight-to-steel. This system could have 4-5 hard drives eventually. Will this case produce a lot of hard drive noise? Is it...

Question about power supplies - multiple +12V rails

I am confused about multiple +12V rails, which are common. I have a S12-380 with two +12V rails. How do I distribute the power load across the rails? Or do I even try? I am replacing the S12-380 with a S12-550 soon - and it has 4 18A rails. The owners manual says nothing about how to distribute the ...

I see now that those two cards are apparently called the Silent and the Silent Magic. The Silent has the V-engine heat sink design.

Any idea if the Silent Magic (cheaper) is close to the reviewed unit?

Do you know if that ASUS card was released with two different heat sink designs? The Newegg phot has a very different heat sink from the unit reviewed by SPCR and the unit listed on ASUS' website.

I have a 3000B case with an ASUS A7N8X Deluxe MB. The front USB ports work fine. I know exactly what you mean about the keyed connector. I can only guess that the problem is with the MB or its configuration. Try another connector if you can. It seems unlikely the ports or the cable are actually bad.

It should be fairly easy to determine if damping will help on a metal panel. If pressing your fingers or hand on a panel reduces or changes the noise and vibration, damping will probably make a difference. Almost any metal will be opaque to higher frequencies. Unfortunately most noise in a PC is at ...

I believe the thicker fans have the same number of blades, but the blades have a steeper pitch (or angle). If all else is equal (mainly RPM), the steeper blade will push more air, and cause more turbulence. The tradeoff then is a more powerful fan at reduced RPM vs. a less powerful fan at higher RPM...

chirs - what I meant to say was that resistance doesn't change with voltage or current. You are correct - the voltage across a resistor will change as Ohm's law says. So if a connector adds .05 ohms of resistance it will cause a greater voltage drop at high current. Thanks for pointing that out.

I think you guys are not really applying the simple principles of electricity to this issue.
