Hi folks I am new to this forum. I have next problem. I use an old dell dimension 4700 pc which was always so loud. Fan started running craizy soon after I start using pc. In a summer time even more. I was wondering if I could improve this situation if i replace power supply with more powerfull power supply. Is that a good idea? Will i run into size or electricity compatibility issues or they are all the same? At this time I have to open my balcony door if i want fan not to run a lot and loud. Thank you, Gene.
