Cooling Duct

Keep in mind, I wrote the following on 07-12-2005, So it's abit out-dated (new hardware) but the concept is the same.

------------------------------------------------------------------------------------------------------

I've been looking around to overclock my AMD Sempron 2400+, and found this little Mod. looked fun, so I whiped up a version of it and... Bugger... me... dead...

http://www.overclockers.com/tips1187/

for an air cooling duct, its the best I've used - AND FREE (well... sorry mother

stole her cutting board...)

for the duct itself, I just used one of those weird-ass cutting boards, you know the type that you can roll up? (ask a woman, maybe your mother

)

For those of you who are lazy... page two is where the party starts. This is the basic mod itself.

As you can see, the CPU fan has basicly been blocked so it cant suck its own exaust air back in. Thats what causes alot of heat. So this duct allows the exaust fan to suck ALL the air out, FIRST time. not fourth, or fifth pass through the CPU heat sink.
(more zoomed out pic, so you can get your bearings)

(these are pictures from the Mod tut, not my PC)

I was running: (three temp sensors, dont ask where. I forgot to check which sensor was where.)
44C
38C
54C

Now I get
30C
24C
45-46C

Thats a 10C drop (or close) everwhere, cant complain with that.

HDDs have no change, but their running around the mid to low 30's, so I'm not worried.

My setup: (07-12-2005)

Original air-flow. As you can see, the air around the CPU heatsink actualy gets reused a few times, before getting sucked out the exaust.

And heres the flow with the duct installed. (got bored... played with CorelPhotopaint)

EDIT:
Here's some temps I just took. I'm currently running an AMD Athlon 64Bit 3200+ (939) Overclocked at 2.13GHZ (Stock 2.00)

New hardware, so It's all running on stock cooling.

Wow thats cool. How did you get so creative?

Creative?

What are you refering to? I was just bored, so I desided there had to be better ways to cool my PC without strapping a watercooling system to it. Did abit of searching, and found a story of exactly what I was thinking of.

Oh Ok. I thought it was pretty neat. I would of not come up with anything like that.

Cooling is a bigger issue when overclocking; why not just get a better processor

But yeah, nice setup; and yes it is creative... Otherwise you would have gone and got a Water Cooling setup or a bigass retail fan/exhaust system
