And since he is blowing the heatsinks out with compressed air every couple of weeks he shouldn't have the kind of blockage that would significantly impair the coolers ability to keep the gpu at a reasonable temp.
It's very common now for card manufacturers to fix the fan speed at a ridiculously low level so they can make noise claims below what might be needed or practical in a real world application. A 5 minute job of raising the fan speeds in Rivatuner is definitely worth a try and won't require dismantling the coolers or dropping a pretty good amount of cash on replacement aftermarket heatsinks.
If raising the fan speeds doesn't work, then you can make your claims that say that we're all wrong and your right.
Actually, I have a HD 3870 in my girlfriends PC Mr. smart guy. And the reason I posted this is because i'm talking from experience. I know because I had to take it apart and clean it out just like I mentioned.
It lowered the temps a little. Then I got rid of that stock HS & Fan and installed the copper zalman that I linked above and guess what? The fan speeds are only on 50% all the time and it doesn't get hotter than 60C.
You're "raising the fan speed" advice simply won't work no matter how cheap it is if the heat sinks inside the plastic cooler is clogged. Which they ALWAYS are based on MY experience with the 6 or so ATI cards I've owned.
I noticed you also advised in another post to buy a new case, aftermarket coolers and a box fan to blow air into the case while he's gaming. So I don't understand why you have to address my post of after market coolers, when you suggested the same thing.
