Sorenbro: I've just build a system for one of my friends, and since he came from using a laptop he is acustommed to very low noise. He wanted a powerfull gaming machine too, but wants it to be very quiet at night were it will be downloading. His best choise is to buy a VIA C3 600MHz machine with a ...

Looking at that calculator I would say that they are counting quite far on the safe side, especially on the 12V line. Your worst problem from the harddrives is that they pull a lot of power when they just start to spin. Fortunately your CPU is very unlikely to be even near high load while your drive...

Have you read the thread How much will a 300W power supply run? A very quick summary of what I think is most important in your case: Your motherboard does not need a 350W PSU.

Does anyone know where to purchase a brick PSU that provides more than 110W? dc2dc.com has a 120W. Available both as only brick and as full kit. mini-itx.com has a 150W, but it has a fan in the brick part. The biggest fanless they have is 110W. The problem with higher power is the heat that is gene...

Well, I would say you have plenty of options. Some require a bit of DIY but are cheap or even no-cost-solutions. You can also buy an adapter or fan controller. The more you are willing to pay the better things you will get. You can easilly run a fan on 12V, 7V or 5V without any fan controller. Makin...

Perhaps you want something like a fanmate but made for 4-pin connectors.
Like this one (from a Swedish webshop):
http://www.gtek.se/img_prod/SF-02BK.jpg
Unfortunately this one only goes down to ~7V.
The fan only connector of the Antec PSU has a varying voltage, and normally they deliver ~5.5V.

Regarding RPM monitoring, do the fans need anything on them... Normally you want a fan with the 3-pin connector to get RPM readout. This means that the fan takes its power from the fan header on the motherboard. Most 120mm fans are quite powerfull, so they might not be designed to take power from t...

ADDA makes some great fans. Panflos are also great, and usually the panaflos are at a lower price. At the same speed the noise from the ADDA and Panaflos should not differ much. I guess that you are probably better off by lowering the speed of your ADDA fans than to replace them with Panaflo fans. T...

From the specs of that computer you should be fine with any high quality 300W PSU. So the power of your current PSU should not be a problem. It seems much more likely that there is a problem with your RAM. Measuring the 3.3V seems like a good idea. I recommend that you run Prime95 or similar program...

If you want a quiet CPU cooler stay clear of the Gigabyte heatpipe cooler. They go for original looks and a fast and noisy fan to get good performance. It is not aimed for silent cooling. AeroCool HT-101 is a good cooler. Be aware that it can only be mounted in one direction, so check how the CPU so...

Cooling 100W of CPU heat is hard, so it will be a bit noisy. (Actually a bit more then 100W since Intel underreports the CPU heat. There is a special thread ab...

It should work fine to control a transistor from the PWM signal and take the feed from a molex plug. I would suggest to use a NPN Darlington transistor with reduced voltage to control it and put the transistor on the ground side.

Putting a capacitor 1uF or 2.2uF in parallell with the Panaflo fan does help a lot to reduce PWM noise. It will however also lower the tourqe of the fan, so the minimum starting voltage should go up a bit. This will more or less smooth out the PWM so it becomes something in between PWM and Linear re...

AeroCool does make very good coolers with great performance at low fan speeds. Heatpipe coolers efficiency increase with higher heat, so if you compare to a regular heatsink and use a high speed fan to keep temps real low they will not give favourable results. If you run a very low speed fan or no f...
