First of all, portables overheat. That's what they do. Second, I TOTALLY disagree with the conventional wisdom of placing a pea sized blob of paste in the center of the heat spreader and spreading it by applying pressure with the HSF. This concept is advocated by people who don't have the manual dexterity to make a PB&J sandwich. These people should not be working inside a computer case in the first place. The proper way to apply thermal paste is to spread a thin layer evenly over the entire heat spreader with a credit card (or other). Squeezing the pea sized blob creates a circular paste pattern on a square heat spreader totally ignoring the corners of the interface. The lame argument made to support this method is that the heat is concentrated in the center of the heat spreader. It's true that the center is hotter but that doesn't mean that the corners are cool. ANY amount of heat that can be transferred to the HSF will benefit the CPU temp especially in a laptop. Think about it. Why would you limit yourself to less than 80% of the available surface area of the heat spreader just because you're too lazy or too inept to spread the paste?

Be sure to spread the paste as thinly and evenly as possible covering every spec of the spreader.. There was an article on Tom's yesterday about pastes. Arctic Silver isn't bad but there are better.

If this were a desktop I'd say those RPMs were very low but you need to check with the OEM to see how the cooling system is suppose to function including fan speeds.

I just read a review of your ASUS that was 4 years old. If that's a good indicator of the age I would think that ASUS still offers some level of support for it. Give them a call. You might be surprised. Also, I would visit the ASUS forums and see if anybody else is having this problem with that computer.

I don't know. Fans usually make noise when they go bad. It won't hurt to replace it but I think you should compare your brother's BIOS settings to your own. Maybe a setting somewhere is preventing the fan speed from increasing with heat.
