So I got a graphics card (9500 gt ddr2) and I overclocked it. It has never had a replacement of thermal paste and was only used for about 1 year before the motherboard apparently stopped reading hardrives and sat in a dusty computer for about 3 years.

I cleaned it with canned air when I got it and overclocked it.
Without overclocks it gets about 70 C max and with overclock it gets about 75 C max (550 MHz to 715 clock and 400 MHz to 520 memory| Highest it can go in msi afterburner and stable also). I also changed fan speeds to by the time it gets 75C it maxes out fan since it had it at 50% all times.

The airflow in my case isn't that great also. Would new thermal paste help a bit and how much would you say? I'm planning on getting it so I can replace the thermal paste for my CPU (been about 11 months) and was thinking I could use some on my old GPU.

I'd like to point out I am using the 9500 GT DDR2 because it plays games slightly better then my APU's graphics and i'm planning on upgrading in a few months or so.

It may help a bit, but I wouldn't expect more than a ~5C difference. If you replace it, get a non-conductive TIM. I recommend Arctic Silver MX-2.

What is the difference? I didn't know there is conductive and non conductive thermal paste.

You want a non-conductive TIM in case you get some on your PCB or other components. If you get something like Arctic Silver 5 on there, you could end up shorting out your card, as it is capacitive and that can cause problems.

At 75C you really aren't near the thermal threshold of the card, you have another 15C to go. Changing the thermal paste could go poorly because many cards have thermal pads in there that you likely won't have replacements for and can't just swap thermal paste in for so you could end up with worse temperatures in the end than you began with. Not being close to max temp also means there is nothing to be gained from reducing temperatures, it isn't going to increase your max OC at all since you said its due to stability so why go to the effort?

Depends entirely on how dry and badly heat is being conducted with the current paste. If its really bad (like it often does with cards this age) it can make a huge difference.

Arctic silver 5 is not electrically conductive.

I didn't say it was conductive, I said it is capacitive.

From your link:

Arctic Silver 5 was formulated to conduct heat, not electricity.
(While much safer than electrically conductive silver and copper greases, Arctic Silver 5 should be kept away from electrical traces, pins, and leads. While it is not electrically conductive, the compound is very slightly capacitive and could potentially cause problems if it bridges two close-proximity electrical paths.)

I was saying it is stable at this overclock. I can't push it farther because MSI afterburner will not allow it for some reason.

Also I don't get what do u mean by thermal pads?

Also it's because Icannot monitor my heat of my CPU (using software at least) and there is bad airflow in my case.
