Initially i had inno 3d 256MB Nvidia GTS graphics card. I also had another Big FAN above the processor (Vendor put in quad core) In that card there was one cable which was joined with that FAN.

Now i have changed the CARD to 1GB Nvidia GT9600 . But there is no pins to join the fan with that card.

Is it ok . i don't know why old card was joined with FAN

Unless you have some mad water cooling system where everything is connected, there is simply no need.

Your CPU should have a heat-sink with a fan and so should your graphics card, they should be separate and not touching or integrated.

If you think this is wrong, please post a picture of the inside of your case, as you must have some weird setup I haven't seen.

I can't say it was wrong as it was running for almost 2 years. But now my FAN is ruiing all day and night and its not stopping. If it runs can it do any harm to processor – Mirage Dec 17 '09 at 0:38
No - the fan should be on 24x7, just running slow when your machine is not at full load. – William Hilsum Dec 17 '09 at 1:09
If it runs at full load all the time will it be a problem. i am using heavy application running 24x7 – Mirage Dec 17 '09 at 1:17
It won't technically be a problem, but when you say full load - make sure it is connected properly and you have a 4 pin fan (that has variable speed control)... Simply, it should work, but you may find the life of it go down hill. – William Hilsum Dec 17 '09 at 9:46
