Tenchusatsu, where did you order the thermally-controlled power supply I got fairly cheap power supplies made by Antec from this place: techstore.com I already installed them, and my impression is that the noise of the power supply is not really perceptible compared to the noise of other components (I guess I can call it a success for now). The fan on the power supply (which is set up to blow the air out of th case) is controlled by thermostat that measures how hot the air coming out of the case is. It spins faster if the air in the case is hot, slower when it is normal. At this point, my case fans make the most noise. I guess one option is to just turn them off, and I think I could get away with it on the PII-400 machine, but the overclocked Celeron needs the air from the air intake. So I got these case fans: crazypc.com They are made by Enermax (they also make quiet power supplies). They have a thermal probe that you can place in the PC to check how hot it is inside the case - the fan RPM depend on it. I just got it delivered today to the office, but I am not there, so I won't be able to tell you how satisfied I am with them until next week. Joe

Tench, Re: You might even want to involve the AMD Mod Squad, since there are more hardware tweakers on that thread than this one. You called for us? Don't unleash the dogs of war again. <g> More seriously: I'm also a big fan of quiet PCs and did take some measure to decrease the noise level of my 1 GHz Athlon system. After switching my CPU cooler to a model with a low noise fan (TwinOrb -- it has two fans but both have only approx. 3,500rpm, so you can barely hear them together) I installed -- just like Joe -- a new fan for my power supply. I chose a Papst 80mm fan, they are very quiet and thermally controlled. It's also a good idea to install the fan in a way that it sucks the hot air out of the tower -- this helps cooling the CPU. With this configuration I could deactivate my case fan and my CPU is still only around 52°C, even if overclocked a little bit. The PC is now more quiet than my old Celeron system and barely noticeable. The most common problem with loud PCs are the cheaps fans: Usually they are very small (50mmx50mm) and thus extremely fast spinning (up to 7,000rpm) which creates a lot of noise. Additional cheap power supply and case fans don't help either. Andreas
