I would use distilled water, and it used to be pretty easy to buy at the store. I remember it being available where rubbing alcohol and contact lens solutions is, but I haven't looked recently. You could make your own, by catching the steam from boiling water. Deionized water is looking to get ions,...

I think that center punches and center drills could be found at home depot. I haven't looked for them there though. I don't think you need any specific type of drill, unless you are really doing a lot of drilling. Typical types are HSS (high speed steel) and carbide. General purpose are porbably HSS...

The best thing is to have some resistance against the back of the surface you are drilling. So using wood is good since you can drill into wood without problems. Perhaps you can use bricks or something to raise the wood and push it against the surface. The best way to make precise holes is to use a ...

I don't think there is a power supply like that, well at least I'm not sure it would be practical to try something like that. But if you get some normal ATX units you will have larger quieter fans and temperature speed control on them. A tray would just be a shelf with the bottom and sides only. If ...

I'm thinking that the water pump will be pretty loud. Using a ~1/2 hp industrial pump which is only able to do about a few gpm, it's very loud. I assume these are 1U or maybe 2U cases? You could move the power supply outside the case and get low noise power supplies. Perhaps some kind of 80 mm fan s...

That would not be a thick enough piece of copper to transfer the heat. The cross section is way too small. You would need a cross section of probably 3 square inches to avoid overheat. I had initially thought of doing this, but I realized the copper part would need to be like 2 x 2 inches. That woul...

I suppose Dell doesn't use thermal paste, but they must be using a thermal pad if not paste. The pads are quicker and easier to deal with for volume manufacturing. Really what you want is an ideal contact between the two surfaces, and just enough grease to fill any voids. If you put too much and don...

You should look at a passive thermal switch like below. Normally open then closes at a higher temperature. I assume this would work fine by just putting it in series with the fan and it will come on once the temp rises high enough. http://www.selcoproducts.com/cfm/ProductDetails.cfm?Action=Close&Sub...

Well one thing to realize is that most of these units, except higher end ones, assume a fixed emissivity. I see normally it is assumed to be 0.95. Which means it is calibrated for measuring temperature on a surface such as a black anodized body. Measuring other items will be less accurate unless the...

The metal on the racks tend to vibrate depending on how thick they are. Usually they are intended to function where no people normally work. The AC fans generally don't have any speed control (on or off). Closed door are likely to generate more of an echo sound if the speed is fast enough, although ...

It is a BX, so it's not the quiestest, but I haven't found the best 120mm fan yet, and I'm not spending time on that now. The main issue for 120mm fans is the clicking or scuffing sound, but it's okay in my config as the fan is on the side of the case away from me. Right now my hard drives are the l...

Useful fan configuration
I've found the Noisemagic NMT-2 coupled with the Zalman fanmate to be very good. http://www.siliconacoustics.com/nmt2.html Since the NMT-2 only goes down to 5V, you can drop that down even more by adding a fanmate. I'm getting a 120mm Panaflo to run at around 450 rpm, which is the benefit of the ful...

I believe that there were some designs for aircraft props which changed pitch of the blade. The pitch changed to either increase thrust which increased noise, or to decrease thrust and lower noise. If there were no pitch on the blade then you wouldn't get any (or very much) flow, but by angling the ...

Athlon 64 3000+ 512kb cache pretty good deal
Well apparently they are selling Athlon 64 3000+ with 512kb cache for a little over $200. That's half the price of the 1mb cache versions. Looks like AMD is really going to push 64 CPU's into the market. That seems like a good deal to me.
