  1. Hi all,

    I replaced my P4 standard CPU fan with a quieter one, its called a cooler master. Only thing is my PC now overheats, i had got a program called Inter Active Monitor and i can view the RPM of the fan, when it gets hot it does not speed up to cool the system down it there a way of sorting this out?

    Thanks

    Paul

    Usually, more quiet means fewer RPMs. Your fan may be maxed out at whatever speed you are seeing.

    Its very difficult to find the right cominbation of cooling and silence.

    Would it help if i fixed a fan to the casing on the back to suck the air out or fix one to the front to blow the air in?

    What is your current air flow setup.

    Most systems benefit most from an intake fan (usually found mounted at the bottom front of the case) and an exhaust fan (usually found mounted at the top back of the case). These don't have to be high rpm fans, Having a flow of air through the case without excessively tangled cables can result in lower running temperatures without having to get a high rpm fan on the CPU heatsink and suffering noise levels comparable to a jet engine ;)

    See the basic patronising image attached for details :D

    Basically cold air in from the front and as hot air rises the fan at the back pulls it out. So the system should have a flow of cool air passing through it. Often the PSU unit has fans as well which assist further in exhausting the hot air.

    If your PSU has 2 fans (one on the bottom to pull air into it as well as one at the back of it) then the best addition would be to have a bottom front case fan attached. An 80mm one at around 2000rpm-2500rpm should be enough.
