i use an hp with bullseye7-386 and it does not support pwm. what can i use
instead of pwm because it gets very hot


Computer model? Processor? Does it have the factory heat sink and fan? Is the motherboard CPU fan pin header 3- or 4-wire? Is the fan 3- or 4- wire?


Does the computer have factory chassis fan(s)? Are the headers 3- or 4- pin? Are the fans 3- or 4- pin?


Boot the computer into Setup and reply with all available fan control settings for all fans.


Very hot under what operating conditions?


Have you cleaned the chassis air filter(s) and the processor heat sink with a vacuum cleaner?
