Return the card for a replacement, the fan could be defective. I'm on my third GT220. The first one didn't work at all and was completely dead. The second one had a very noisy fan. The third one was bought at a different retailer and has worked flawlessly for over a year now.

Ok I thought it was that model that was the problem me.. but for returning that and so on that will take me one month or two to get the other one back..

Do you think if I disconnect the fan and put and external fan on the side of the PC will do the necessary for cooling it?

I wouldn't recommend that course of action, pulling the plug of your GPU's cooling fan is like spelling out death for the processor. If a simple side mounting computer case fan would do the trick, than most video card companies wouldn't waste the bucks on producing cooling solutions for their cards, they would just run with the computer case cooling solution option. That small fan is on top of that GPU for a reason, I wouldn't mess around with it!

+1 to what Zen said, bad idea.

Ok I see now..but what can I do then because the noise is too much annoying like a wahsing machine working or a printer at work. I don't know where to get the thermal grease so I can't open and change the fan.

You should be able to get the thermal paste at the same place you got your video card, wherever that is. As for warranty issues when removing the fan/heatsink, that depends on the brand. You said NVIDIA, but who is the manufacturer? e.g. eVGA, PNY, Palit, Gigabyte...

I bought it on ebay but I will try to see if I can get it as computer parts reseller here. The card I don't know there is only Nvidia GT220 written on it..nothing else I was thinking of seeing something like EVGA, PNY but nothing.

Now be advised, if you do the following, you are doing so at your own risk! I will not be held liable and or responsible if something goes wrong!

I've done this twice for overly noisy CPU motors and fans and once for a noisy fan atop one of my old video cards.

Take a very lite amount of traditional "3 in 1 oil, tilt the video card upside down, so the fan in pointing at the floor, with the eye dropper end of the oil dispenser, give the post that the fan is built on a couple lite drips of the oil. Then hold the video card upside down for about 2 to 3 more minutes, then carefully turn the card "right side up", as so the fan is pointing to the ceiling. Watch to make sure the oil now is using the fans post to slip down and get into the motor mechanism. After about 1 minute of the oil sinking into the fans motor and housing turn the card back "upside down", bust out a hair dryer, plug it in and set the fan to blow out a medium amount of cool air. Allow the hair dryer to blow air on the fans post and motor for about 2 to 3 minutes. Confirm there is no longer any active oils on the fan blades, the post and see if you can look where the post meets the motor, confirm there is no active oils there to. Once you feel certain that the oil in the exposed areas is now dry, plug the card back into it's slot inside the computer and "go for broke"!

It should work, it has for me in the past, quiets old and new fan motors and posts down to a gentle whisper.

Good luck....................."Remember, own risk"!

I don't think that's going to help much.
Make sure the thermal compound is not conductive.

Hi,

I bought my new PSU a 450W one and its working fine but the noise still here.. But I see that when I put the fan to 100% the sound didnt change.

I attached some photos and a sound clip recorded from my phone. Hope this may help to solve the problem.

Thanks in advance
