New Video card cooling

Hello all, I am currently running an 8400GS 512MB PCI in my Celeron D. I have a question about cooling. I currently am using a fan that I salvaged from an old AMD 450MHZ CPU. It plugs into an IDE power connection. As of now, it seems to be cooling it ok. It fits right on the heat sink. This is a Sparkle Computer Card, and really my first REAL accelerated GPU. I switched this with an Nvidia 32MB that ran better than the onboard 64MB. Anyway, I aquired a larger fan out of a power supply. The power lead fits the card and I have devised a way to fashion it to the heat sink. My question is what is the voltage and amperage levels for the fan connection on the card? The Fan I want to use, is made by Protechnic. It is a MAGIC. power specs are DC12V 0.24A. If I plug this into my card, will it function properly. I also should be able to control the speed with Nvidia tools or FanSpeed if it is plugged into the card. Like I said before the fan I am currently using for the GPU is a fan that connects right to the IDE power supply. Gimme a reply, I am new at all of this, but all of my experements have worked so far. Email me at darthrtviets@aol.com

I would highly reccomend paying for an aftermarket heatsink insted of playing too much with additional fans on the graphics card. While bigger fans make small difference, a bigger better heatsink, with higher quality/conductivity contact material (copper) makes a HUGE difference. Also the way the heatsink contacts the processor on the graphics card is very important, thousands of PC modders apply "Artic Silver 5" to the bottom of the graphics card heatsinks(where it contacts the processor) and have large drops in temperatures. The compound costs about five to ten dollars, and most neighborhood radioshacks have it in stock.
If your interested in getting a new heatsink: (See GPU heatinks at newegg.com) 

Just make sure its compatible with your particular card.

Does the DG31PR motherboard support Geforce 8400GS 512MB PCI-E?


Yes, but check your BIOS and make sure the PCI-E slot is enabled.

Also, when you say doesn't start, you mean just the screen? Right?

About geforce 8400gs gen2 tc1g 64bit ddr2, it is okey to run in window7 32bit. i already install and run but only read 512mb.


There should be no reason why this card won't work with Windows 7 32bit, it could be as simple as your Graphics drivers are out of date. I recommend downloading the latest Windows 7 drivers for your card at the Nvidia website.

Just remember graphics RAM and SDRAM are two completely different things so they don't add up.
As far as I know the 8400GS is a 256MB card.
