I personally find it easier to pour water straight on the keyboard, everything becomes much cooler at that point. But really, I am wondering or should I say I would like to verify or at least make sure I am not doing something wrong before I hit that precipice. Every now and then my macbook becomes too hot for me to touch. This is me playing games or running DVD creation software, nothing out of line, not something that i do normally. But since it is summer, my macbook seems to be at a constantly higher temperature and runs the fans more often than during the winter. ( I did leave windows open during part of the winter for ventilation) So I came on an idea, which really is a stop gap. I take a drop of water from a cup and wipe it on the handrest/ wrist area and it is cooler because the heat is transfered to the water which then evaporates. I never put water down in significant quanitities, nor do I let it sit there. I spread it out over the surface so that it does not fall down into the area of the keyboard. I know that the area where the handrest is where the battery and harddrive are located, not the cpu or motherboard. I have never wiped water over any part of the keyboard even though that is where the heat is coming from. So am I a big fool who has already voided my contract with water damage (even though no damage has occured) or is it benign as long as it never goes and touches the electronics itself and keep to a minimal amount.
