Windows 7: Help With Laptop CPU Overheating!

Help With Laptop CPU Overheating!

I have a sony vaio with windows 7 that I purchased 4 years ago. the specs are:
- i7 CPU quad-core
  • Max clock speed: 1734MHz
  • Current clock speed: 1734MHz
  • External Clock: 133Mhz
  • L2 Cache size: 1MB
  • L2 Cache Speed: MHz (doesn't show number. just says "MHz")
  • L3 Cache size: 6MB
  • L3 cache speed: 0 MHz
  • Current voltage: 1.4v
  • Load percentage: 5%
- 8GB DDR ram
- 500GB HDD
- NVIDIA GeForce GT 330M video card

My problem is actually a couple things. First of all, my laptop IS SO UNBELIEVABLY LOUD every second it is on no matter what. The fan never turns off even if I have no program open it is going full blast most of the time and is so freaking loud. Secondly, my CPU is constantly at 180 degree's Fahrenheit according to SpeedFan software. The speedfan software says my CPU, GPU, System, Temp1, Temp2, Core 0, Core 1 are always each around 180 degree's Fahrenheit. From what I read, that doesn't sound good! Also, the corner of my laptop where the CPU/fan is will literally burn your finger if you touch it for too long....

Other notes:
- When I monitor my average CPU/Memory usage, my CPU Usage is below 10% and Memory shows around 2.75GB. Also it shows 328MB paged memory and 147MB nonpaged memory.
- I have always had my pc optimized for best performance and I have disabled so many "crap" programs/services from running as well as nothing at startup so please don't mention anything about programs being an issue because it happens with no programs even open(even in safemode).
- A couple of times the computer restarts out of nowhere with no warning or blue screen. just literally restarts immediately. I think this might be some mechanism to protect overheating?
- I have optimized my pc with Windows 7 Manager which initially helped the problem but now the problem is non-stop.

Some questions:
1. Is there a setting to stop the fan from being on constantly?
2. Is the fan on constantly because of the heat I can feel near the fan/cpu, or is the heat I feel near the fan/cpu CAUSED by the fan being on non-stop?
3. There is no visible dust/blockage on the fan/cpu. I have not opened it up but I have used co2 shots to clear way and that did no good..

any help is greatly appreciated!

180 F is about 82 C, which is quite hot, but not at the critical level. Laptops are rarely cool.

Do you get the same temp readings from multiple temperature-reading programs?

If those temps are accurate, I would expect the fan to run non-stop.

Do you know if your fan RPMs are higher than they have been historically?

Laptops have small fans. Small fans have to spin at high RPM to do anything worthwhile. Is the fan noise louder than it was 6 months ago or 2 years ago?

What is "Windows 7 Manager"?



I seriously doubt the fan running at high speed is causing any significant amount of heat.

Is the high heat a recent development? If so, your fan may be failing and not able to cool as it had done before. If not, the fan be in good shape and just reacting to heat as you would want it to do.

You should also clean your laptop out with a can of compressed air. Blow the air into the intake and output vents for the fan. Be sure to keep the compressed bottle upright and blow some of the air out before blowing it into your laptop as their could be a little bit of liquid built up in the nozzle and you don't want to blow that in your laptop. Also, don't let your fan spin up to a super high RPM when blowing out by blowing the air in short bursts. This should help with your laptop heat.

thanks for the info. I forgot to mention that I have also been using "cooler master" laptop stand which has two big fans that blow into the laptop from underneath. Yes multiple programs report the same 180F temp. As far as fan RPM, I don't know anything about that. Is there any place in windows 7 to adjust fan RPM or even see the current RPM?

As far as blowing compressed air, do I do it while the laptop and everything is on? The part of the laptop that is the hottest is where the power cord plugs into and if I look in through the vent there I can see a bunch of copper. do I blow in there?

Yes, you blow out the vent on the bottom where you can see the fan underneath and blow out the exhaust vent where you can see copper. As for controlling/seeing fan RPM, if your laptop let's you do this, you should be able to tinker with that using SpeedFan: Download SpeedFan - Access temperature sensor in your computer

Laptop overheating
Hi all, I work on a DELL laptop. It sends out very heat air from its vents. I think probably there is some (or large amount of) dust on hardware devices inside it. I know that best way is to open it and clean those pieces by (say) an air compressor, but there are two points here: 1- Do you...
