So, I have a Sony Vaio that very recently the fan started running continously. Before, the far would run upon start up and then stop. Occasionally, it would kick on and then off again but now it runs all the time. It seemed to start after my nephew downloaded a Lego game. After reading online about some of the possibilites I ran Adaware and also I looked at my cpu to see if anything was amiss there. The Adaware came back with nothing and the cpu looks fine. Any other ideas of what could cause this? Should I be concerned? TIA.

Run this app and let us know what the temps are...

Core Temp

I cant see your temps since im at work and its blocked but here is my guess. Your pc is probably dirty inside(dust). Its probably causing your chip or video card to run hotter than it should.

Or maybe you added a program that is taking up more cpu power running in the background or something like that.

One last thought. You can try elevating your laptop to clear the inlet vents and/or change your power settings.

How technical are you? When my fan starts running loud/constantly I pull the keyboard off and clean it out. I can do a much better job that way than just blowing it out with compressed air.

Also, you might try researching Sony message and support forums. There could be some weird known issue causing the fan to kick on.

I am just a tad handy really. I just may try taking the 8 screws out of the bottom and see how it goes.

"It seemed to start after my nephew downloaded a Lego game." Some flash games are brutal in the way they use processor cycles, just the way some DOS apps keep a continuous polling going for no other reason than that was the way the coding worked. I would suspect some part of the game or component running in the background. Cleaning your fans and keyboards won't hurt, but if the problem doesn't go away, look towards that download as the next possible cause.

Cleaning a keyboard won't do anything to cool the cpu. I think the person who wrote about removing the keyboard was simply saying for his laptop that removing the keyboard gave him access to the cpu cooling related parts that needed cleaning.

I think simply using compressed air should be sufficient.

The TjMax is the maximum CPU temp defined by the manufacturer of the CPU.

Looking at other forums concerning your system the values are OK...

Safe Operating Temperatures (Sony Vaio CW)

Have you noticed any unusual smells coming from the system?

Checking for debris inside it won't hurt...

Some excellent video's on taking apart your system (don't know which model you have)

NFN, assume it's a Windows system...

Have you tried bring the system up in Safe Mode and let it sit to see if the fans stop? Would indicate something heavy is running in the back round in normal mode if they do...

I decided to uninstall the game which really didn't help much. After that I took compressed air and blew into every opening on the side of the laptop. Not sure if its my imagination or not but after this and rebooting the fan is running what seems to be normally. I think ill keep my eye on it and go from there.
