my computer run smoothly and quietly when I run windows applications but when i run a game like GTA San Andreas the fan rotates at high speed and I am able to hear the noise very well. I have no graphics card. This is my computer configuration
Pentium 4 D 3.4Ghz , 945G Intel Motherboard , 512MB DDR RAM , Windows XP SP2, 160GB HDD.
should i buy a graphics card if so what card ?
Do you have another fan you could try it with, or has it done this with other fans?
Yeah get some software to monitor your systems temperature to make sure everything is running smoothly. As for a gfx card i would recommend an ATI Radeon 9250 256mb it's value for money. Can run most latest games with a processor like yours. I currently have an ATI Radeon 9250 and the gfx are breath taking, although it does depend on the game you are playing also, Electronic Arts tend to make games with good gfx like Need For Speed Underground Series.
9250 is old chipset
i have a 9600XT 128MB from Radeon but it is AGP card but my new motherboard supports only a latest PCI eXpress card
They won't affect the performance in any shape or form. I think they are good value for money as i currently own one having to have a low profile gfx card in my desktop pc so i have no choice but to use one.
Change the paste, try another cooler...
And for graphics card I'd choose Radeon 9550, 256 mb.
I used it myself for two years (until last month), and it still works fine with all games.
