Thermally Advantaged Air Duct

I just replaced the Athlon 64 3200 (A8V Deluxe motherboard) with an X2 4600. I'm using the stock heatsink (the large one with four heat pipes) and built-in thermal pad. Lightly loaded for Web surfing it runs at 44 degrees, about seven degrees warmer than the old 3200. Running some Photoshop filters I've seen it get up to 48 degrees (SpeedFan indicates the temperature). No overclocking, no AMD dual-core CPU driver or Cool and Quiet. The case temperature is 31 degrees.

I have a two year old Inwin "thermally advantaged" case (not sure of the model number). It has a plastic tube air duct attached to a grille on the side of the case that's supposed to fit over the CPU fan. With the old CPU the duct didn't align perfectly with the fan. With the new CPU, a bit less than 2/3 of the tube is over the fan.

Is the duct/tube doing anything for me? Would I be better off removing it? I don't understand what it's supposed to do anyway. Would I benefit from installing the AMD Dual Core CPU driver, which is supposed to adjust the clock and fan speed according to load?
 
I would remove it and mount a 80mm instead. Yes, you will benefit from installing that driver (at least I did when I went from a 3200+ to an X2 4200+) as well as the dual core optimizer.

I've only seen the dual core optimizer mentioned in connection with games. Does it do anything useful if you're not playing games?
 
Hi,

The "thermally advantaged" duct only heklps is the case temperture is really high.

Assuming your room is somewhere above 20C, and with the case at 31C, the thermal advantage will be worth at most 2 or 3C in your CPU temp.


And your temps are fine anyway.




The AMD CPU driver does a number of things. One of them (just one) is to ensure the two CPUs run at exactly yhe same speed. Some games depend on the CPU always running at the same spped for timing events (they should not, but they do) and can crash if there are two CPUs available but running at slightly different speeds.


Other things the driver does may be of benefit - I run it on principal; but all the machines I built before I started installin gthe CPU driver worked exactly the same as far ai I could tell.


I don't run CnQ BTW, on the grounds that it only makes the machine run cool under low load; and frankly any fool can make the machine quiet in idle.

I installed the driver and enabled CnQ. The CPU now runs at 31 degrees most of the time (with case temperature 30 degrees). I also installed the AMD Power Monitor, which also provides a convenient way to disable CnQ (by selecting a power scheme other than "Minimal") should I ever need to.
