COMPUTER COOLING

Namen diplomske naloge je izdelati hladilni sistem, krmiljen z operacijskimi ojačevalniki. Sistem je vseboval štiri temperaturne senzorje, s katerimi smo merili temperaturo. Na osnovi te temperature smo krmilili hitrost vrtenja ventilatorjev. Tako smo omogočili tišje delovanje računalnika ob manjših obremenitvah in boljše hlajenje ob visokih obremenitvah. Temperaturni senzorji so bili nameščeni na procesor, pomnilnik, grafično kartico in trdi disk. Temperaturna senzorja iz procesorja in pomnilnika sta bila priključena na vezje, ki je krmililo en vpihovalni in izpihovalni ventilator. Temperaturna senzorja iz grafične kartice in trdega diska sta bila priključena na drugo vezje, ki je krmililo drugi vpihovalni in izpihovalni ventilator.The purpose of diploma thesis was to produce cooling system controlled by operational amplifiers. The system included four temperature sensors with which, we measured the temperature and on the basis of this temperature was fed the rotational speed of the fans. So we acquired the computer to run quieter at low loads and better cooling at high loads. Temperature sensors were installed at: processor, memory, graphics card and hard drive. Temperature sensor from CPU and memory, have been connected to the circuit, that controls one blow in and blow out fan and the temperature sensor from the graphics card and hard drive to another circuit that controls the other blow in and blow out fan
