    Need a cooler desperately for Asus F3SV

    Hi all,

    Just got my laptop back from being repaired under warranty, apparently the problem was a few components had burnt up and stopped working properly due to overheating. I've therefore been advised to get a laptop cooler. A simple enough task it would appear...

    The problem I've got is simple. From what I've read, some coolers draw hot air away from the underside of the laptop and push it out the bottom/sides. Other coolers do the opposite, pushing cool air into the bottom of the laptop. Now which one do I choose?

    I've heard it depends on whether your laptop draws cool air from the underside and pushes it out the back/sides, or if it takes in cool air from the back/sides and pushes it out the bottom.

    Laugh if you will, but I can't seem to work out which category my F3SV fits into! It has one exhaust vent at the back on the right, which is where the graphics card is. The only other vents are on the bottom, one underneath the graphics card, and a larger one in the centre. There appears to be a slight cool breeze coming from the exhaust port on the back, which is where the graphics card is, and this has led me to believe that cool air is taken from the bottom of the laptop and pushed out the back, and as such, I would need a cooler that pushes air into the laptop. However, the fact that there is the other larger vent on the bottom with no matching vent on the back would suggest that blowing cool air into the bottom vent, with no where for it to go, would not be a good idea...

    Any ideas?

    cheers

    I have an ASUS F3Sv sitting on the desk next to me. It has one fan. That pushes are out the vent on the back-left side. The air is drawn in from the other vents in the laptop and any cracks between the case parts. The vents underneath are placed so that most of the air comes in this way and is drawn across all the components before getting to the fan.

    Before you do anything, you want to check what temperatures the laptop is actually seeing. Get HWMonitor. It will show the CPU, GPU and drive temperatures. Unless these are constantly going above 90C, there isn't really a problem. But, if there is a "slight cool breeze" coming from the vent, then the temperatures are very unlikely to be a problem.

    I don't use a cooler, so I can't advise you on one. There are two things you can do:

    - Make sure the fans and vents are clean. The fan is under one of the access panels on the bottom so it is easily reached.

    - Try undervolting following the guide http://forum.notebookreview.com/showthread.php?t=235824.

    Between the above two things, I dropped my idle temperatures from about 55C to 45C and the maximum from the 85C to 70C.

    There is a cooler buyers guide and a cooling guide here that should help.
