How I made my Dimension 4600 quiet

You may incur another cost in the future as a result of slowing down your
case fans.

I eliminated all HD noise by removing the Dell supplied HD's and
installed a Maxtor PCI-SATA/150 card which connects now to dual Maxtor
Diamonplus 120gb fluid dynamic bearing drives

not only are the Maxtor SATA drives totally (and I mean *totally*
silent), they are ultrafast as according to drivespeed analysis tools
the existing IDE's had seek times of 80-95 milliseconds, the SATA's
have seektimes under 10 milliseconds

another advantage of the Maxtor SATA's are that according to internal
drive temperature readings (available via low-level tools accessing
drive SMART data), they run at about 91-96 F when the previous drives
were 30 degrees hotter

Is it any good with the leaves?

I always thought diodes were rectifiers working like a gate rather than
lowering voltage .How do they slow down a fan?

Yes, but as a side effect they decrease the voltage by 0.8 V each
(in the pass through direction).

Chris, how did you modify the new power supply?

Did you have to modify so that it would fit inside the Dell case?

I own a Dimension 4500 and might want a quieter power supply like yours.
