has anyone tried air ducting? and got simliar results?

"Results of New Heatsink and Ducting

Ambient temperature (the temperature in my bedroom) for all tests was around 28C (82F). This is unseasonably hot for June in Toronto.

Initial results with Chrome Orb (thermal pad):

Case 36C / CPU 46C at 800Mhz, default voltage IDLE (no load test done)

Final Results with ductwork and Evercool ND3 heatsink with generic thermal grease:

Case 34C / CPU 35C at 800Mhz default voltage IDLE

Case 35C / CPU 39C at 800Mhz default voltage LOAD

Case 35C / CPU 39C at 900Mhz max voltage IDLE

Case 35C / CPU 44C at 900Mhz max voltage LOAD"

yea, I read that article and it convinced me to create a duct for my 1800XP. The temps really do come down. I creaded almost and identical duct (120mm on one end narrowing down to 60mm? Cpu fan)

My idle tems before were around 55C
Now the're at 46C!!!

I have a 3 way switch for my fans (12V, 5V, off). At 12Volts and with the duct work in place, the added push of air caused my CPU fan to go from 4600Rpm to 5700 Rpm. At night when I sleep I switch it to 5 Volts and it quites down a bit and the cpu fan slows to 4800Rpm.

I would reccomend!!!!

i managed to find 2 case fans out of no where which connects to the PS cables and not to the mobo.

i've put one at the bottom front blowing air in and one at the top back blowing out.

Idle Temps before: CPU=48C, Case=32C
Idle Temps now: CPU=46C, Case=27C

now i'm happy with the case temp.

gonna make one of those air duct thingy hopefully my CPU temp go below 40C.

Yeah I "ducted" my crappy $30 case about a year ago. All it took was a $10 hole saw drill bit and some PVC pipe and a flange. Since then it's kept the following setups nice and chilled:

Athlon 1.4 @ 1.65 GHz, 2.05V
XP 1800+ @ 1.73 GHz, 1.95V
Dual XP 1800+ @ 1.67 GHz, 1.85V
XP 2200+ @ 2.0 GHz, 1.9V
P4 1.6A @ 2.3 GHz, 2.0V
P4 2.0A @ 2.6 GHz, 1.85V
P4 2.5 @ 2.95 GHz, 1.85V

took me a few hrs to get that hole on the side panel, its my first time making holes
made that cardboard duct thingy, and it failed to drop my cpu temp...dont know why.
so i'm gonna use those aluminium flexy pipe thing, whatever it calls, to lead from the cpu fan all the way to the side panel and no gap. where with the cardboard duct method there's a gap between the cpu and the cardboard ductor.
