Dimension 3000: P4@2.8GHz. NOISY - alway has been. Want to remove green shroud permanently, add quiet 80mm thermistor-controlled fan to CPU stock heatsink (without exciting a BIOS temp alarm), replace...
As for the green shroud, I would not recommend removing it. The computer case is designed to correctly circulate the air through the system and safely out. As for replacing the fans you can replace them with anything you like, just make sure the new fans are the same dimensions they come in szies 40, 60, 80, 92, 120, 140 and a newer 200 mm form factor so you can just measure them if you don't know the correct size. Next look at where the fans plug in, if it is a three pin plug then they fan's are kept at optimal speeds via the motherboard and bios. So they are already controlled by heat sensors / thermostat so to speak. If they are 2 pin then they just run full speed usually. For the back fan just make sure it is the right size and pin out. You can hook a 3 pin fan to a 2 pin fan plug on the board it will just run full speed all the time. For the CPU fan buy a combo fan/ sink and just make sure the sink is the same as the existing one so it will fit on the motherboard. You could probably get rid of the green shroud if you went with a really high end fan / sink for the CPU but that's up to you. For the thermal paste it is easiest to put a small blob in the center of the CPU and then use a plastic card, such as a drivers license to spread it out to cover the entire CPU, thinly and evenly. Add small amounts if you need to to cover the entire surface. Try not to have a bunch oozing out the sides although it won't really hurt if it is.
