Project Graphetto 6450

post #1 of 5
Thread Starter 
I got this card Asus HD 6450 1gb ddr3 "silent" used for $29 for an upcoming project, I hooked it to my HTPC to test it and got the HW reading, 80C load and 60C idle ohno-smiley02.gif
So I decided to do something about it
I took the heatsink off thinking about getting a heatsink+fan that fits and went to FRYS,




I didn't find what i'm looking for so this is what i got : a 50mm fan and new thermal paste ( please feel free to ignore the tea in the background tongue.gif )



after cleaning :



work finished :



results :



that's about 25 degrees lower load and 17 lower idle thumb.gif

Grats, it's amazing what a little bit of air movement will do to a passive heatsink.

Any reason you chose pull instead of push with the fan though?

I would advice you put the fan on the longer fins instead of right over the core. Would allow better airflow and probably cool better as well.

Because of the heatsink shape i thought if it' was a push most of the air will hit the center all metal part of the heatsink and will not go through the fins

I was thinking of that too, probably will add another fan there in the future and try to overclock this card (my upcoming project).

I would try both just to check it out, would only take a few minutes to swap and test temps again. You may have to move it slightly off center so its not on the flat part like Android said though. If you're really feeling adventurous I bet you could extend the space between the fins into channels(not all the way thorough of course, just channels) with a dremel or something to increase surface area and make it more suited to active cooling. That design was clearly made with passive cooling in mind.

Temps are already a ton better, but there's no harm in always trying to squeeze a little more out of a mod smile.gif.
