Looking to subtract 2-3C from your temps? Instead of investing in a $12 80mm hairdryer, take a look at the ducting mod by ThermalTake. It's a simple, cheap mod that my friend is using for his Athlon. He's running at about 2C cooler and it cost him $10 bucks at a local store but you can find them cheaper elsewhere I'm sure. For one, it reduces back pressure, the fan spins faster and with less noise because nothing's pressing up against it. I'm going to get one as soon as I figure out how the hell I'm supposed to mount one on an SLK-800u.
Your post got me thinking......
I, like you, have an slk-800u. After thinking about this for a while I figured out a good way to mount one of these to your heatsink:
Take an old 80mm fan that you are not using and cut out the motor assembly leaving only the outer shell. Mount that with your heatsink clips and bolt the duct mod to the 80mm shell.
Well I looked around a bit and found somebody has already done that, except not for this duct mod.

I remember a lot of discussion about the effect of the dead spot in the middle of traditional fans and wonder if raising the fan to help eliminate the dead spot is really the benefit of the duct mod...
I have a TT SmartFan II ordered and will receive it this week. I think I am going to try this out and see if it helps.
I have also thought about using one of these Overclockers kits from SVC mounted to one of my intake fans to bring the coolest air directly to my HSF.

My current temps aren't severe, but any improvements are always welcome.
