All,
There are two switches on the right side of the case on the Mach III. The switch to the front controls the fan (turns it on when up, and off when down). What does the other switch do? At present it is in the down position. I noticed recently that the core temperature at idle is running around 58 C, which seems hotter than it should be. The Mach III is inside a cabinet without a back and some decent ventilation. Wondering if the Mach III should not be placed inside a cabinet.
R.

Hi Ramesh,
58C is very normal, but best would be if the fans don't switch on in order to maintain it at that level. I think at 61C the fans switch on.
Of course, in a cabinet the heat will build up somewhat; also with decent ventilation.
Do you regularly undust your Mach III ? that will really do wonders if you never do that (you will see what I mean if you take off the cover).
Btw, switch Down means On (you said it the other way around).
That other switch increases the "steady fan" speed somewhat. Down is higher. Thus, especially with a warmer ambient (say 100F) it may be necessary to increase the fan speed somewhat, so the other fans stay off. Thus, having those on/off all the time (white led goes along with that), is not the best for a steady sound.
I hope it is clear a little !
Peter

Peter,
Thank you. Clears it up. Front switch down is ON--my mistake. Back switch down means higher speed for steady fan. I'll take the covers off and dust the Mach III over the weekend.
Sound is fantastic.
Ramesh

Use monitoring software to keep an eye on your Mach III's temperatures, especially under load. If temperatures are consistently high (above 80°C under load or 60°C at idle for CPUs), it's a sign of potential cooling issues.

Thank you Anatole. I use CoreTemp to monitor the core temperatures. Recently, and in the new cabinet, they range from 58-61 idling, and rise to about 63 under load. The back of the cabinet is open, and if I open the front doors, the idle temp drops to around 55. Part of the issue is not a lot of clearance on the sides. I'm going to experiment a little. Contingency solution is to place the Mach III on top of the cabinet. Of course, that will upset other residents of the household!
