Ghetto-mounted GPU cooling

So my graphics card (Radeon 3870) runs pretty hot, and it normally takes manually adjusting fan settings in SpeedFan to keep it below 50. I was getting sick of this, so I went to see if I had a fan with a 3-4 pin connector anywhere. I didn't, but I did have a proprietary Dell 5-pin fan. So I just stuck it in my case, jumpered the red and black wires to 5V and GND on an Arduino respectively, wired a USB power cable for the Arduino through the back of the case, and put the panel back on. It already seems to be making a difference, but will this actually improve performance at all?

Wont improve performance any, just help prevent it from thermal throttling which would impede it (Wouldn't do that until about 90c though).

Ok, well, I guess that's worth it.

might bring temps down a small amount but thats about it, it wont be getting any additional preformance if its already staying at 50C

I spent $2500 on building my PC and all i do with it is play no games atm & watch anime at 1080p(finally) watch YT and write essays...  nothing, it just sits there collecting dust...

Builds:

The Toaster Project! Northern Bee!

"Here is some advice that might have gotten lost somewhere along the way in your life. 

 

#1. Treat others as you would like to be treated.

#2. It's best to keep your mouth shut; and appear to be stupid, rather than open it and remove all doubt.

#3. There is nothing "wrong" with being wrong. Learning from a mistake can be more valuable than not making one in the first place.

 

Follow these simple rules in life, and I promise you, things magically get easier. " - MageTank 31-10-2016
