Audio amps have significantly different thermal characteristics than do CPUs. For example a typical class AB amp is about 70% efficient. Therefore with 100 watts output (to the speaker) there is about 35 watts of heat that needs to be dissipated at the power transistors. In addition in a typical aud...

I did almost the same mod as Boomer. The differences were: 1. I mounted the fans just like the stock fans. 2. I wired the fans into the stock internal wires. The result was a very quite PSU that has been in place now for about 7 months without any problems. My (perhaps not very well done) near field...

I have used both CPUIdle and VCool. VCool is free and at least on my machine works as well as CPUIdle. This type of software functions because the OS invokes the HLT instruction when ever it enters the idle loop by flipping a flag in the BIOS to make that instruction to actualy work. This reduces po...

I have the same problem with my setup. I am under the impresion that this is fairly common. In my case I beleive that it is because of the controller which is a RAID controler.

There is a long earlier thread where the use of an enclosure box was a significant topic. This design was the focus of a number of posts in that thread and it's principals of operation were expounded on in some detail. Here is the link http://forums.silentpcreview.com//viewtopic.php?t=2442 Since thi...

I have a system very much like yours. But I don't have your concerns about keeping the keyboard powered during an outage. I have an APC BackUPS 700 with the PC, monitor (19"), printer (Epson 1270) and film scanner on backup with everything else on the conditioned lines. When I go into the software f...

There is a small possibilty that this could have shortened the life expenctancy of your CPU. But these normaly are obsolete long before they die. So if it is working now I would not be concerned about this.

I have used CPUIdle and did not notice any instability on my WinXP system. I tried some other software coolers and most of them did have instability problems. I am now using VCool and with certain setting it was unstable. But with some experimentation it is now stable. I also tried undervolting my C...

I also use MBM. I have found that with my mother board the HLT command does not result in cooler temps without running cooling software. I am curently running VCool and this lowers my idle temps by about 22*F over what I see without it. I am running Win XP.

An LC circuit is an capacitor (C) and an inductor (L) connected together. This is a circuit that acts as a band pass filter that resonates where the frequency of the effective resistance of L = the effective resistance of C. This is called a tank circuit and it is used extensively in RF (radio) circ...

What did you find?

Mike and all, I did not mean to imply that cabinets of this type would increase the noise levels althoug under exactly the right this could happen. But rather that if the noise properties of your components were well understood and if you had the right algorithms and enough computing power it should...

The frequency of the tunnel resonance it dedendant on three factors. 1. The volume of the chamber connected to the tunnel. 2. the cross sectional area of the tunnel (speaker builders would call this a port) 3. The lengh of the tunnel. The larger the chamber the lower the resonance frequency. The lon...

Most systems even fairly "high powered" ones draw way less than 200 watts. For example my XP 1800 two disk drive system just breaks the 100 watt mark at idle (with idle cooling software running) and peaks out at about 150 watts fully loaded. I am almost certain that most 400 to 500 watt PSUs designe...

XP 1800 stock speed and vcore (1.54 GHz, 1.75V) 2 120mm under volted fans 1 intake 1 exhaust. Case temps are very low - about 4C above room temps. The reading is from the CPU diode. So the temps are warm but OK for such a low noise cooler. Under normal conditions I almost never see temp go more than...

I am running one of these. With room temps around 21C I see idle temps around 49C and max load temps around 68C. I have started running CPUIdle and this dropped my idle temps to around 38C. I have a well cooled case with MB temps around 4C above room temps. The heat pipes feel very warm when there i...

Another way to go is the NoiseMagic controller sold by Silicon Acoustics http://www.siliconacoustics.com/nmt2.html . This controller is designed to mount on the fan housing. But it is easy to modify. In my case I have put standard 3 pin leads on it and put the thermister on a longer wire lead. Event...

I have a 120mm low speed panaflow that will not start when I connect it to fan only connector on my Antec TruePower PSU. I have not checked the voltage of this connector but I suspect that it is around 4V when the PSU is cool (most of the time). I have other fans that are fine with this connector.
