I switched my components from a hp slimline s5760uk into a bigger case, and upgraded to a 500w PSU. My computer is really loud, by the looks of things its coming from my CPU cooling fan. I never noticed the noise as I was transferring it but i didn't have the side of the case on then, nor was it loud in the old slimline case. Now, Is it because its just vibrating the airflow onto the opposite side of the case, and because there is ALOT of space, is just magnifying the sound, or is it another problem. I have tried to slow it down using SpeedFan, but I can't seem to be able to actually slow it down. Basically I can hear my fan going round but its loud, currently running at 1422RPM
Thanks
