Modern computers are devices rather "greedy" on the part of electricity.Power consumption of a typical desktop computer gaming with modern monitors with LED-backlit, even at rest, often more than 100 W, and during the game (ie, when the load on all components dramatically increases), this figure increases at least 2-3 times.
consumption of mobile computers, of course, much smaller.This is due, on the one hand, the need for a long time on a laptop in standalone mode, and on the other - is problematic discharge a large amount of heat from the components, packed in tight plastic (usually) body.
In many cases, the reason for choosing a laptop instead of the usual desktop is a need for mobility, or simple lack of space for a full-fledged computer.And in fact, and in another case, the user is often forced into the work / play / reading keep the laptop on your lap.Which is sometimes the most "laptop" good was hot.And strong heating affects not only the comfort of working at the computer.The higher operating temperature of the "iron", the less battery life.In the case of a hard disk prolonged exposure to temperatures above 50 ° C may even be fatal.To reduce the likelihood of such sad consequences, the user handy gadget such as a cooler for the laptop.Stand
cooler laptop (namely, this form factor is used in these refrigeration systems) may be made both of metal and of plastic or of a combination of these two materials.Advantages of metal obvious: durability, lightness, a presentable appearance.Besides laptop cooler made of aluminum itself it is a kind of heat sink, cooling the bottom of the computer even without active cooling.However, such devices tend to have greater value as compared with plastic counterparts.
Another parameter that characterizes the notebook cooler - size.It is obvious that for computers with screen sizes 13.3 "and 17" rack need different sizes.Too much the device will be overweight, and too small will not be qualitatively perform its core function - the cooling of the bottom housing and convenient placement of your computer.In addition, the notebook cooler is too large can not banal way to get into the bag, which also is adjusted for the size of the mobile computer.
next important parameter - the type of cooling.It can be passive or active.Passive cooling - absolutely quiet, becauseno moving parts.Notebook cooler off device of this type, first, through contact with the bottom nouta and secondly, due to the appearance of the gap between the housing and the surface.Active cooling means that one or more fans that encourage air flow under the bottom of the computer.Fans can be of various sizes - from small high speed and extremely noisy "Carlson" in diameter 40-50 mm massive 200-250-millimeter products.This type of cooling is definitely much more effective passive, but it has two minuses:
- noise and vibration.Many stands are equipped with manual speed control, manufacturers used instead of plain bearings, hydrodynamic bearings are used to increase the diameter of the fan, thus lowering their momentum, but to get rid of noise and vibration is impossible.
- fans require additional power supply.Usually it is served on the laptop through a USB-cable.According to it, you can pass a current voltage of 5 V, and the power of up to 0.5 A, which is enough for the "valve", require 1-2 watts.But this is an additional load on the battery.
Some stands have built-USB-Hub, PC Speaker, lights, and sometimes even space for an external hard drive (usually the size of the disk is limited or 1.8 "or 2.5").To support these features may require additional power, which is provided by an external power supply.Even eminent manufacturers often "forget" to put it in a box, so the user has to buy additional power supply separately.
from the model something concrete is difficult to recommend becausemanufacturers regularly update their product line.The main advice - to avoid the production of well-known Chinese firm NoName.Among the most significant players in this market should be noted Zalman, Cooler Master, Antec, Xigmatek, Logitech.Many manufacturers of computer peripherals second tier, such as the Trust, Canyon, Belkin also has in its range of notebook coolers.Do not disdain the release of these gadgets, and some manufacturers noutom.
