T-Bird & KT7-Raid

I have an AMD Thunderbird 1ghz CPU. It was mounted on the Abit KT7-Raid with a standard heat sink and fan that came with it. It was running at 43C max load. I went to Home Depot and bought two pieces of flex tubing. I took two extra heat sink fans and mounted each one to an opposite side of the heat sink, one blowing into the heat sink and one sucking out of it. I attached each flex tube to one of the two fans and the onther ends of the tubes went to the back of the case. This way the standard fan cools the CPU with air from inside the case. The two other fans suck air from outside the case, through the heat sink, and blow it back out the back of the case. Now my CPU runs at 33C max load. That's a 10C drop in temp. And my system temp. is down 5C. It only cost me $6 for the tubing and I already had the fans. It's worth a shot for a cheap temp drop. Let me know if it works 4 U.
 
good idea... bypass everything but the cpu... vent it... great try that in my next box... whats the easiest way to mount fans on the sides of heatsinks?

you do not strengthen the weak by weakening the strong
 
Great idea...I did something similar with my GPU by creating a foam wind tunnel from my side pnl fan to the
HSF....but the channeled exhaust is an interesting idea.

I'm not in touch with my feeings, and I like it that way!
 
It depends on what type of heat sink and which way the fins are facing. Sometimes you can get a screwto hold right in between the fins of the heat sink. If its facing the other way, you'll need to drill atleast two holes in the heat sink and put screws in the opposite corners of the fan. It actually works very well. Cool air is brought directly to the cpu, cooling it faster. And the hot air is expelled directly out of the case, which doesn't heat up the rest of the machine. The only tricky part was connecting the flex tube to the fan. After a lot of trial and error, I found the easiest thing to do was use a hot-glue gun, or even crazy glue.
 
Just one more thought on the exhaust tubing idea...If the tube is too long for the fan to push hot air all the way through to the exit...it will backup the heat to the CPU again. So either the exhaust tube needs to be short enough
to keep air flowing all the way through...or the fan has to be powerfull enough to do the same. I only point this out because a long tube with an insufficient fan could actaully increase the CPU temp.

That's a good point, I didn't think of that. Both tubes are short in my machine. If you need a long one, you could always add a second fan to the tube to help push the air.
 
can ya post a picture, cause thats a really good idea and i wanna see how u attached the tube n stuff
 
hey gotta comment! how would one 'vent' the exaust from a chrome orb?

Yes, I'm the BOY who got Win98 to load in under 10 sec... ah....
