Computer Fans

Computer Noise

Executive summary about Computer Fans by Michael Arcand

computer cooling fan

Computer noise is normal … somewhat. Your computer has at least two fans, one on the CPU (central processing unit, or the brain of the computer) and the other on the power supply unit.

Two more things that generate noise on your computer are your CD-ROM (and DVD-ROM) drives and your floppy drive (if you still have one!). Any noise that appears abnormal from these devices probably indicates a problem with the device. For example, a grinding noise in the floppy drive may indicate a bad floppy disk, or a bad drive.

It will sound exactly like any other fan bearings that you might have heard go out … from an air conditioner unit to a box fan … the fan bearings all sound the same when they start to fail.

Get to know your computer! Some noise is normal … but excessive noise from any component on the computer usually indicates excessive wear and tear, not to mention possible eminent failure.

Taming Your Very Noisy Computer

Executive summary about Computer Fans by Victor Epand

Does your computer drive you crazy with all of the noise? There is a simpler solution than having to purchase a complete computer. Check out these ultra quiet cases. They are much cheaper than a new computer and they are the quietest on the block.

The first case we reviewed was the Nexus Clodius Ventilation Pro Series. This quiet case has it all. It not only solves the problem of noise, it also solves the major problem you are having with heat if you are using your computer very much.

This quiet case will also allow you to mount an extra 80, 92 or 120mm fan on the top of the case as well as one on the bottom of the case. With all the ventilation holes on the top as well as the bottom, the airflow of your computer is totally solved.

Ventilation Pro Series quiet case has anti- vibration rubber feet which prevents resonance from the case.

SilverStone SST-TJ10B is based on the Temjin TJ09 chassis. It has totally perfected the fusion of a classic tower case with the newest technology around for a chassis.

This case has a mid-section air duct which does the job right by bypassing the hard drive cage with a 120mm fan. This 120mm fan draws the cool air from the room which offers additional cooling for those extended length graphics cards.

The Antec Sonata III is a very popular quiet case. The Sonata case is can be optimized with your choice of Nexus power supplies and Nexus 120mm case fans. Other features are the chassis air duct that will keep all the graphic cards and CPU running cool.

Custom Computers

Custom Desktop Computers

Executive summary about Custom Computers by Marcus Peterson

custom built computers

Personal computers today are custom-made for various uses. One can buy media center PCs that are solely built to watch movies, rip music, edit movies, and the like.

Gaming enthusiasts can also get desktop computers that will enhance game play and provide high-quality graphics so that every game can play itself to its fullest worth.

The cheapest way to go about getting a desktop computer is to purchase individual computer components. In doing so, you can get a fabulous desktop computer, assembled for your needs without straining your budget.

There are many manufacturers out there who custom make desktop computers for users. Also, hunting for individual computer components is easy, and you can assemble your own PC.

Today, if you mix and match you will get the perfect fit - and if you want the perfect custom-built desktop computer, you have got to mix and match. It is also recommended that if you are going to invest in a custom desktop computer, invest in quality parts.

How to Build a Custom Gaming Computer

Executive summary about Custom Computers by Chris C. McCann

The key elements when it comes to building a custom gaming computer are a muti-core processor, high end memory and lots of it, and a very powerful video graphics card with lots of video memory.

Most of the garbage computers that buy off the shelf at the major electronics stores are just not adequate for gaming. They are really built for word processing and surfing the Internet. So obviously the bulk of the computers for sale at these big retail stores are built for simple tasks.

If you truly want a high end gaming system you are going need a custom built computer. You can call around to your local computer companies. I would suggest you research the parts you want, get the exact spec’s that will perform the way you want, purchase these parts individually, and then assemble the computer yourself.

Laptop Power Supplies

Solar Power for Notebook and Laptop Computers

Executive summary about Laptop Power Supplies by EM Beck

hp laptop power supply

The solar cells that you see on calculators and satellites are photovoltaic cells or modules. Photovoltaics, as the word implies (photo = light, voltaic = electricity), convert sunlight directly into electricity.

The energy knocks electrons loose, allowing them to flow freely. For example, the current can power a calculator. This current, together with the cell’s voltage (which is a result of its built-in electric field or fields), defines the power (or wattage) that the solar cell can produce.”

As energy costs and energy conservation continue to garner interest as mainstream issues, we should see the rapid development of solar integrated design features.

Hand Held Solar Kits

Solar kits combine solar cells, rechargeable batteries, and a wide selection of cables. These won’t power a portable laptop yet unless it’s a miser on energy, but they will keep you connected with a limitless power supply for your cell phones, Smart phones, PDAs, and smaller devices.

Portable Solar Power Docking Stations

The idea of using solar power in remote situations is nothing new. The question for us is how well, and how fast, a solar power station will power up your notebook or laptop.

There are very few winners in the category of a portable solar power docking station to efficiently run a laptop computer. One that does get good reviews on the subject is the “PowerDock System”.

PowerDock Systems are relatively expensive, and range in price form a few hundred dollars on up to $450. The PowerDock is an attractive product design an weighs in from 5 to 13.5 pounds.

Another potential winner is the Notepower Solar Laptop Charger from Sierra Solar Systems. The 3 lb. Notepower is not designed with a storage battery, but the 20-30 watts of power will charge and run most laptop computers, according to the specs.

You may not consider the Notepower as a true solar docking station, but it is an attractive portable solar package for a temporary power solution. Originally priced around $250.

Commercial and Military Grade Solar Power Systems

Some of the best remote solar power systems are designed to meet military standards. Energy Technologies, Inc. in Ohio, USA makes a wide assortment of military standard power equipment for field use.

Things like field deployable inverters, converters, UPS, engine-generators, along with solar power stations with the trade name Tactical Solar Products.

We have looked at several of the many possibilities for solar power, and going “green” with remote computing. Some of the solar power resource websites you might want to keep an eye on include: Altapower.com, RadioLabs.com, and CTSolar.com. As computing devices become smaller and more mobile, and with nascent technology soon to push the boundaries of wireless networks, solar power could prove to be a factor in your computing future.
