because they needed large amount of power to operate to vacuum values.
In 1946two Americans, Presper Eckert, and John Mauchly built the ENIAC electronic computer which used vacuum tubes instead of the mechanical switches of the Mark I. The ENIAC used thousands of vacuum tubes, which took up a lot of space and gave off a great deal of heat just like light bulbs do. The ENIAC led to other vacuum tube type computers like the EDVAC (Electronic Discrete Variable Automatic Computer) and the UNIVAC I (UNIVersal Automatic Computer).
the eniac and other computers like to give off so much heat because they use thousands of vacuum tubes that took up lots of space and gave a great deal of heat just like a light bulb does.
Oh yes - and for several generations after that. ENIAC, the first mainframe computer, had to be kept in a room with very heavy air conditioning (about 60 degrees) because of the heat generated by all the vacuum tubes.

A heat seeking missile is basically a homing missile, that only searches for heat (there is lava on one side and a computer on the other side. The heat seeking missile will hit the lava because lava is WAY HOTTER than the computer).
No, computer heat will not affect anybody.
ENIAC was designed for one purpose and one purpose only. The human computers at the Army's BRL at Aberdeen were totally overwhelmed computing firing tables for all the new models of Artillery and new conditions in which they operated in during WW2. ENIAC was supposed to do these calculations faster. Work began in 1942 but it was not completed until late 1945, so it was not able to contribute to the war. Its first big problem was simulation of Teller's "Classical Super" fusion bomb from December 1945 through January 1946, which showed that it could not work due to excessive radiative heat loss.
1946: The Eniac Computer is UnveiledENIAC (Electrical Numerical Integrator And Calculator) was originally developed during Word War II to perform complex trajectory calculations for artillary, but the war ended before the machine was operational. But it continued to be used after the war, performing calculations for the design of the hydrogen bomb, weather prediction, cosmic-ray analysis, thermal ignition, random numbers, and wind-tunnel design. The ENIAC contained 17,468 vacuum tubes, along with 70,000 resistors, 10,000 capacitors, 1,500 relays, 6,000 manual switches and 5 million soldered joints. It covered 1,800 square feet of floor space, weighed 30 tons, and consumed 160,000 Watts of electrical power, making the lights go dim in Philadelphia each time it was powered up. On October 2, 1955 the ENIAC was shut down for the last time, but by then inventors John Mauchly and John Presper Eckert had already had the UNIVAC computer on the market for several years.
it helped heat up houses but was more advance than other fireplaces because it gave more heat and produced less smoke
A heat spreader is used to help draw heat from your ram. The average computer user does not need a heat spreader, but someone that has a powerful gaming computer may benefit from using it.
Any individual who has a computer or more than one computer in their household, should be concerned about monitoring the heat of their computer systems to maintain their proper running and overall longevity. The placement of computers in the home can have an affect on how hot they may become; therefore, their placement should be carefully considered. Computer heat monitors are an important factor in keeping up to date with the temperature of the computer system. Some software programs can allow for an individual to see the temperatures of the motherboard, processors and other important components. However, specially designed computer heat monitors which can show more accurate and up-to-date readings, can be bought for home computer systems.
Outdated hardware, heat, high voltage and many other things, I reccomend reading on tomshardware anandtech and many other tech websites if you seek to become more tech knowledged !:)
