Cool-stick is specifically designed to solve the problem of quietly cooling flat-panel displays recessed into walls or cabinets. While no one device is suitable for ventilating every installation cool-stick is the answer to many problems. Damage to expensive displays from heat is a real possibility. Cool-stick can help you avoid this problem with its 16 quiet fans blowing stream of air across the back of display panel. With mounting brackets that gives the installer flexibility in mounting. Cool-stick is small enough to squeeze behind, below or above displays in all but the tightest situations. Minimum 1-inch gap above and below the display is required. Cool-stick has sixteen fans, two power supplies and two thermal switches for high degree of reliability through redundancy. Miniature power supplies are used to ease installation in crowded enclosures. Shorter version cool-stick 18 is also available. Supplied with a single power supply and thermal switch, cool-stick 18 is useful for mounting behind components in tight quarters such as between closely-spaced shelves.
