    I've had my 7801u since about june or july and like most people here they treat their computers like their own children. I use a can of air on all the vents everyday weekend to remove the dust, and i have the nc2000 laptop cooler. I've noticed though that since i've purchased it the idle temp for my 9800 starts to increase as time goes by. When i first purchased this laptop the idle temp ( sitting for about an hour doing nothing) was about 31-32 C, but over the last couple of months the idle temp has gotten to about 45-48 C. Nothing is obstructing the vents, and i have the laptop cooler sitting flush with the laptop i.e. not moved forward or backwards or turned around.

    I'm using the latest version of the Dox drivers, running win7, and i use an external monitor which the native res is 1920*1080. (no change in temp using just the laptop monitor)

    I'm wondering if its the thermal compound or something else. I'm not sure what i should try. Standard drivers? different cooler? send it to gateway? i'm not sure.


    any tips?

    Thanks in advanced!

    Most likely dust build up and/or thermal compound problem.

    To completely clean the fans you will have to strip the laptop down, but if your not comfortable with that then don't do it.

    Also if the ambient air temperature in your house/flat has increase due to central heating etc, would also cause the temp to go up a bit.

    I had the same thing happen to my 6860, which was very surprising to me as I hadn't had it very long, it had been in a clean environment, etc. I cleared the vents and fans of dust by 1) putting a long thumbtack through the grille and between the fan blades to hold it still, then 2) using air to blow in the fan side, then back through the vent, then into the fan again to work the dust out.

    My temps immediately went right back down to normal and my machine is nice and quiet again :)

    If you don't have a long thumbtack to hold the fan still (it was just handy at the time) you could probably double up a twist-tie for the purpose. Doesn't matter what, as long as you don't let the air spin the fan as that can damage it (and then you can't run the laptop).
