Sometimes it matters what DOESN’T work as well as what DOES.
I built these ducts out of cardboard and glued the fans into the ends. These and the blower duct were all taped together around the heat sink and precariously anchored to the case. The blower was perched atop a box and taped to the blower duct. The vacuum duct air was also directed away from the intake of the blower. This whole thing was done with the case cover off. You should have seen how goofy it looked!
Now I know this isn’t the most scientific way to test this but I just had to know if it would make a difference.
Well, for the record, it didn’t.
I think the process was working because I saw my motherboard temps go up by about 4 degrees. The air from the heat sink that was usually going out in all directions, was being sucked out through the vacuum ducts. So, if the motherboard thermistor is located near the Northbridge, it wasn’t getting this air dispersion like before.
My final conclusion is that the Taisol aluminum heat sink just could not transmit and release the heat any faster. If the problem was that there was not enough fresh air getting through the heat sink then by pulling the heated air away from the heat sink as well as forcing it into the heat sink would have helped the temps.
At least with this setup, the most benefit would come from using cooler air from the start. And I know in my system, cooler room temp translates to cooler core temps by nearly 1 to 1.
Later next week, when I get my Taisol with the copper base, I may try this again to see if that heat sink would benefit from this idea.
Anyway, it was fun trying.
Questions, criticisms and comments are all welcome!
