I have a Sony Vaio VPCF1, It is overheating, I downloaded speedfan and according to it Fan#2 in not working. The CPU fan is running 5160rpm. the CPU cores are at 180 degrees and the GPU is at 175. What is Fan #2 and can it be replaced? or is my computer done. I noticed this problem after the DC power port was replaced, is it possible the fan was not plugged back in or not inserted properly? Please Help

I am sorry i did not give enough info. I have been using a laptop cooling pad on a desk or my coffee table. and I am still getting the high temps.However, I no longer get the shutdown I was getting before the pad. While gaming, I play mostly Fallout New Vegas on medium settings, back when the computer was new the fan speed would change with the load on the GPU and I could play on high settigs. It would get pretty loud too, nothing that concerned me. Lately, I haven't been hearing it. I did take the keyboard off and the fan is spinning. I also noticed that there is not a second fan. I dissasembled it while I waited on a reply to my post. I tried to update the Bios but I am alreadyup to date. Any Ideas, I am thinking the fan is going bad, but want to make sure before I spend the money on a new one.

Also I was reading on the internet that it could be the thermostat on the mobo that is bad, can that be fixed?

Well, I am assuming those temps are in Fahrenheit, if the system does not have a header that would be described through speedfan as "Fan #2", then it will not present any value for it; i.e., it is looking for fan #2 but because your laptop does not have one, it says it is not working. Just my guess, if ^ is actually from Sony just ask them!

I called sony support and all I got from them was "Your laptop is out of warranty, Bring your laptop to a sony service shop" I decided to take it in to my local computer repair shop. I'll pay the $49.99 diag fee to find out what it is and then fix it myself. Every place I called seems to think is a dust problem, and the fan and cooling fans are clogged with crap. I wouldn't have that kind of luck though. It will be somthing that requires a motherboard replacement probably. At best, the fan is going bad and that would need replacing. I will find out next week.

I found the problem. Even though my fan and heat sink did not look like they needed cleaning that was the problem. I used a canned air and cleaned out the heat sink fins. Now my laptop works like it did when it was new.

I had the same problem in my VAIO. The reason sppeedfan reports no speed for fan #2 is that there is no such animal; just a CPU fan. This is where the problem lies. Actually 2 problems. Over time, the exhaust from the fan accumulates dust inside the box where the fan blows the hot air out. The second, I suspect larger problem, is that the thermal paste SONY uses, to put it blumtly, sucks.

You need to remove the cover from the laptop to get inside but this wasn't as bad as IO thought it might be. Lots of help here on the web. There are about a dozen small screws, just don't lose any.

Once that's done, you need to remove the fan/heatsink; another dozenish screws. You will have already bought: Arctic Silver thermal compund and cleaner ($12.99 at Amazon). Follow the directions and use the cleaner and surface prep liquids to thourouhly remove the old compound between the copper heat sink and the processor. While the fan is off, use the brush attachment on a vacuum cleaner to remove all the dust accumalted at the exhaust port. Now apply the Arcic Silver, sparingly (a dab'll do ya), reinstall the fan/heatsink, put the box cover back on and and be cool, VERY COOL!

Oops, forgot to mention, my VAIO now runs 30C (almost 100F) cooler and I can't hear the fan anymore because it's turning so much slower; it no longer needs to turn fast. Between this fix and the SSD I replaced the hard disk with a while back, this puppy is cool, silent and fast.

I'm sure they can clean it but it's really not hard to do it yourself.
