Sony laptop overheating

by dkowalske / February 15, 2008 10:20 PM PST

Hi,
I'm sure this isnt the first time someone has had questions about this. It seems to be pretty common. I need to take the whole fan out of my laptop. I am able to open the laptop up and I can see the fan unit. I just cant tell how you take it out of the computer.
Maybe it just pops out. I'm a little nervous about pulling on it becaue it looks like it is attached to a heat sink?
Thanks for any info

Sony Vaio

Usually a blast of the compressed air (more)
by R. Proffitt Forum moderator / February 15, 2008 11:22 PM PST

After I place a wood stick in the fan to keep it from turning a few blasts for the compressed air can usually gets the dust and lint out. I rarely remove the heatsink fan combo.

Bob,
Thanks for your reply. I did clean out the fans with compressed air,
and the fan is still running non stop, and it overheats within an hour of heavy use. Is it easy to pull out the fan unit?

The bottom line is this is a PENTIUM 4 laptop.

It will overheat. This is a well known bad design so all you can do is add a laptop cooling pad to extend the time till it overheats.

If you have followed my advice over the years you may have seen me slam this CPU as a "never a good idea" for laptops.

Bob,
Thanks for the help, the laptop was bought in 2003. Wish I would have seen your post before I bought it.

Any time extender is to get more air space under the laptop to let the air move more freely. I used some big old pencil.

I have taken the fan off a similar VAIO once
by double_clutch / February 16, 2008 8:21 PM PST

Hi, a few years back a friend of mine with a very similar looking VAIO (also P4) was overheating and fans were going full tilt. By taking off the panel around the keyboard and taking out the dust pads, the laptop didn't even need fans when started up again. In your case it could be that there are two fans, as on the one I cleaned, and the fans can be taken out without force. So if you get the other one cleaned out, I think that should do it. Also, the two fans I'm referring to are not on the CPU heatsink. If in doubt you can take some pics, hopefully we'll be able to do some remote surgery Happy

Thanks for the info. Do your remember if you just pulled the fans straight up and out of the board?

I vaguely remember there was one small screw on the plastic grille of the fan. It was in plain sight so it should be easily accessible. Generally with computer components, and laptops especially, some force may be needed, but of course within reason. I accidentally broke the little bit to screw the fan down, but even without it the fan went back into the system with no problem.

fan removal

There is actually a metal casing around almost half of the fan blades with the middle open. This metal casing has four screws that I tried backing out. They seem spring loaded. I know it sounds weird. I was nervous so I didnt loosen up any of the other three. Maybe I should try to get the cover of that off. not sure.....

If you're not comfortable with removing the fans, then don't

In reply to: fan removal

The reason I would recommend taking the fans out would be to make sure all of the dust is removed. If you think you've gotten the dust out, just leave the fan. Try to look if there isn't a second fan or if there is dust blocking airflow somewhere.
