The stock heatsink is not good enough... reaching 80 degree Celcius...

THat's not much more than the 8800GT. Have to say tyhe 4870 has a much
better HSF design though as it exhausts the heat out of the back of your
case. 4850 doiesn't and dumps the heat in your case. If you are going to
change it look for one that exhausts the heat out of the case. Arctic
Cooling makes those but not sure if they have one for 4850.

Thanks. I just noticed that the stock fan speed was not at 100%. How
could I make the fan to always rotates at max speed via hardware? Asus
has a software solution, but I don't wanna bet on it.

I remember seeing a thread somewhere about new firmware that changes the fan
profile.
 
jumper. Best way is to plug the fan directly to the 12V line from your PSU,
or to a motherboard fan header. You will need one or two cable adapters:

You sure that it's 12V? :P
You may want to first run the fan at 100% using Rivatuner or ATT, to make
sure the noise is tolerable...

Now using Asus' SmartDoctor to run the fan at full speed.

Actually it is. I have a stock XFX 8800GT that maxes out at exactly 65C
and idles at 50C. Considering that the 4850 has a chip limit of like
90+ before it stops working, the high temperatures are something to be
concerned about. Also high temps tend to shorten a chip's life greatly.

I'm waiting on revised 4870's with new coolers to replace my 8800GT. I
really like the new 4800's and it's a shame they have such an easily
fixable flaw.
