<h2>{{ .Title }}</h2>
<p>While working on my main X58 SLI build, I wanted to test some RAM in a known good motherboard. I had enough spare parts minus a PSU and GPU to assemble another working system, so I picked up an old EVGA GT 630 and Fractal Design Define R5 Window. The case will be another entry, as I have a lot to say about it. Unfortunately, the GPU runs its fan at almost 100% at all times which is extremely annoying. While fine for testing, my end goal with this system was to be a media center PC since my DVD player is pretty bad and I didn't want the main SLI system to run just for video playback.</p>
<p>I tried re-pasting the GPU die, and that didn't do anything. Temps reported 39°C, not that warm... stopping the fan with my hand for a minute only brought the temp up a few degrees, definitely within reasonable opperating temp. Some further reading has lead me to believe that manufactures of these low end cards only baked in two speeds, low and high.</p>
<p>I found a video where someone soldered in a fan control potentiometer. Since it was run at full resistance, it could be replaced with a single resistor, but I have a spare controller on hand.I thought about soldering but didn't want to modify the card or the controller, so I just forced the fan connector into the controller... Not ideal, but the pins sort of fit.</p>

<p>After some testing to make sure it was working, it was time to install it. Luckily, the mounting hole was perfect for fitting it to the PCI slot I/O bracket.</p>

<p>At the lowest setting, the fan is about equal to the sound of the case fans, which is perfect. After playing back a DVD and streaming YouTube for an hour, the temps stayed at 45°C even with the significantly lower fan speed. It should work out quite well.</p>
