Does a side case fan only have little effect on GPU cooling?

After putting a 120mm side case fan, my Video Card temperature only dropped about 0.5° to 1°.



The side fan is at full power is blowing directly at the side of my Video Card where the Heatpipes, heatsink and fan are located, maybe about less than 3 inch apart.|||Fans either suck in cool air, or blow out hot air.

Fans help a lot, but I don't know if adding more and more fans will help that much, so 1degrees may be fair. However, I bet if you used a little ingenuity you could place the fan in a better position to either suck in cool air, or blow out hot air. Hope that helps.|||I assume you were measuring temperature when the card was under load such as playing a game? This is when you would see the biggest difference from improved cooling. If you were measuring when the card was idle,like just displaying the desktop, then temperatures would already be low so could never be reduced much further no matter how good your cooling.



If you already had case fans installed and they were already doing a good job of moving air through the case then adding more fans wont help much. there comes a point where adding more and more fans has little of no effect.



Steve|||Most likely, the fan had little effect because the video card was already running cool. It probably just caused the controller to spin the fan on the graphics card more slowly.|||you want your side fan expelling the hot air that the GPU fan is kicking out. blowing the air back into it is defeating the purpose.|||I think the best way is to elevate your computer so that you can get it exposed to more places so it can cool faster.|||u can't expect a massive drop in temp juts from a side fan dude. if u really want to improve temps dramatically u gotta get liquid cooling.|||have an intake and exhaust case fan, and also fan blowing air to your GPU's heatsink and components
