Sony Vaio VPCEA24FM resting on a Belkin cooling pad (which is very poor product). CPU heating up quite quickly.
No air coming out of the air exhaust vent tested with the back of hand, tried feeling air on the cheek. Looks like fan is working, noise is quite clearly auidable. Below image of SpeedFan test.

  1. Can I be sure that fan is still working?
  2. If yes, why I cannot feel any exhaust air?

Dust buildup in the heat sink? –  LilCodger Mar 12 '13 at 18:51
    
@LilCodger Amy suggestion for solution? Warranty expired. 3 year old. –  Gaurav Agarwal Mar 12 '13 at 18:54
    
Straight from the horse's mouth: kb.sony.com/selfservice/microsites/… If you're up to it we can check for a service manual and crack the sucker open. –  LilCodger Mar 12 '13 at 19:00
    
@LilCodger Yes..yes I want to do it...i want to open it... –  Gaurav Agarwal Mar 12 '13 at 19:04
    
Having trouble finding that one, as Sony is quite stingy. Here's a Youtube tear-down of one though: youtube.com/watch?v=q3CYuDh-S5A –  LilCodger Mar 12 '13 at 19:20

Given the age and the description, I would guess you have dust buildup in the CPU heat sink.

You can try using a vacuum/shopvac to suck it out, but for best results open the notebook up and clean out everything.

A teardown video is at http://www.youtube.com/watch?v=q3CYuDh-S5A. Sony is unfortunately stingy with the service manuals (money in service).

Have some compressed air, likely a #0 Phillips screwdriver, and if possible some Arctic Silver. Since you'll be in there anyway it's probably worth replacing the CPU thermal grease.
