Air Cooling Tweak!

post #1 of 11
Thread Starter 
I came up with another air cooling idea to lower you processor temps. My last guide involved ducting air to the processor using 3-4" aluminun ducting (from hardware store). For me, this dropped by temperatures 5C. My next guide is to cut a whole in the bad of you case directly behind the processor. Then mount a 80mm fan there. You can further aid the cooling by using a buffer that eliminates the dead spot from the fan. I used the top of a pack of CDs. This addition tweak has lowered my CPU temp another 4C.

Nice, I had been thinking about how hot the back of the motherboard must get, and that mod seems rather simple, especially since I've got these 6 masscool fans just sitting around that I got from newegg.

Only problem is that on some motherboard you will also have to use your dremel tool to cut through the mobo rack. One of my cases was ok, but the other one needed the additional cutting. Turned out to be rather simple also... Only took about 30 minutes. You have to take out the motherboard though

The back of the motherboard dosent get all that hot, as the die is insulated by the chip pcb and the air gap in the socket, or on 939-40(dont know intel though i would assume lga775) the centemeter of plastic of the socket. The only way this mod would lower temps is that it would move air a bit around the case. It would lowe case temps probably if it were an intake. I dont see it having much use as an exaust.

Try it as both an intake and an exaust, I'm intrested in the results.

I testing both methods, and having the fan blowing on the mobo was most effective.

I think you are wrong. When I touched the metal tray that the socket was directly on top of, it was hot to the touch. The mobo was also hot under the socket after I cut out the tray metal. Also, 4C drop is processor temp if proof enough that it works.

I have my mobo siting out on my desk running, and when I touch the bottom of it (done by shutting it off and lifting it up) its warm, about 2-3C° above room temp.

As for the woking part its likely that just the intake of cold air was helping.

Maybe its the difference between Intel and AMD. I would say mine was about 35-40C

4 degrees isnt enough for me to hack up my nice thermaltake case. now my ghetto case on the otherhand... hehe, dont have anything to run in it though.
