It sounds like either your cooling system has failed, or Dell under-engineered it.

How old is the laptop?

Can the system run with say a 50% load on the CPU with the stock cooling without overheating or triggering any type of thermal overload circuit?

Download Prime 95 and set it up to use both cpu cores and run it for at least 30 minutes, and download speedfan, coretemp, or everest. Use one of those to monitor the temperature of your laptop. If the temperature goes higher than 70 degrees celcius, you might wanna get another cooler. If it stays lower than that, forget it.

Just FWI, I killed my laptop's battery running FAH on it 24/7. The temperature got around 67-68. It used to get 2:30 when I first bought this laptop back in may of 2007, now it gets 45 minutes. Heat is the enemy of batteries.

It is, but Li-Ion batteries also lose about 25% of their capacity per year, whether or not they're actually used. Excessive heat can boost this number to 30% sometimes 35%.

Ubuntu and notebook hardware control say my battery's health is at 40%. That's way over the average yearly battery degradation. Good thing is that I got the 3 year warranty on this. I wonder if bestbuy will replace the battery. Probably not, but it's worth a shot.</thread derail>

If you read the fine print, the battery is usually only covered for 90 days.

nvida GEForce 8400 M GS

speed fan is posting 54 degrees with my borrowed cooler (from my 12 inch lap top) under it. Dunno about the high end, but since this thing will see action on weekends when the office hace no AC i want to keep it cool all the time. I'm not really concerned if its over kill i just lie kthe security of over cooling.

So suggestion for a 15.4 laptop cooler?

I believe dell has a speed fan control software( i8kfangui ), besides speedfan which is more on the desktop not on the notebooks.

laptop coolers only provide ample air movement to the exhaust fans to your notebook..they are more likely to provide are air intake to the fans, but its up to the notebook fans to flush out the hot air inside the notebook chasis, even if your cooler cools down the surface under the notebook its still hot inside if the fans wont blow the hot air out, so the key here is to maintain a certain speed for your notebook exhaust fans to keep a certain level of temp. Forcing the fan to run at a constant speed should keep it cooler than having it run on itself..when it hits 60 or 70 deg cel..
