I felt that my Vostro laptop is overheating. I downloaded a tool named SpeedFan to test my internal laptop temperature. Speedfan gives the following measurements:

Temp1: 75 C
Core0: 70 c
Core1: 71 c 
  1. Are the measurements good, or does the laptop have a problem?
  2. What is the best way to reduce the laptop temperature?

I always put the laptop on a table when using it, for better air flow.

I agree with HopelessN00b, this is not the place for these types of questions. – Dresca Jun 19 '12 at 16:38

If this is the temperature under load, it's quite normal. If not then it's a bit on the high side. First thing to do is to dust the fans out, when dust gathers on the fan the airflow is worse and the cooling element can't give off enough heat.

To dust out your fan, just open the fan cover and use an airduster to clean it out. Be sure to lock the fan in place so it doesn't start spinning (you might break it otherwise). enter image description here

If a table isn't working you can buy a special laptop cooler. It is a plastic pad that tilts the laptop and has some extra fans on the bottom. enter image description here

By "lock the fan in place", is there an actual way to do that or should you just push something up against the blades so they don't spin? That what I always do. – ChimneyImp Jun 19 '12 at 16:54
No you have to hold it manually, pushing it is not good, preferable use a wooden toothpick and stick it between the blades, hold it while you spray it. – Lucas Kauffman Jun 19 '12 at 16:59
That's what I meant, yeah - hold something against the blades. You got my hopes up that laptop fans had a switch or something that locked the fan so you could clean it. – ChimneyImp Jun 19 '12 at 16:59
No that would just cause a lot of overheating laptops because people forget to switch it off :p – Lucas Kauffman Jun 19 '12 at 17:25

My Vostro 3500 was at 75 - 78C. CPU load is 33% and I am not doing anything with my computer. I checked the Task Manager, selected to show all users process and found that the Digital Persona (the fingerprint reader) was using 28% of the load. I killed the process and overheating is gone. Now is in a 45 to 55C range. I will follow instructions to clean the fan.

Hope this helps.
