HEAT ISSUES on M645-S4050

When I first purchased this laptop I thought it was an incredible machine.
It did everything I wanted it to do and more.
Now, ~6-7 months later Im experiencing a lot of heat issues.
If I use it for anything but office apps, light web browsing, and light photo editing the thing BSODs on me.
Best guess it that the GPU is getting too hot on the count of the fact that the screen will freeze and I get a buzzing sound from the speakers just before the BSOD.
I checked the PC Health Monitor and it reads as:
CPU 60+% on the temp scale
FAN 70+% on the speed scale

SpeedFan reads as:
GPU 115F
HDD 93F
Core 0 124F
Core 1 115F

Recently I adjusted the the power setting to have the CPU to run at 50% and the GPU to run on battery optimized even when plugged in.

Ive noticed only a small improvement on the readings.

Could someone please advise me on how to fix this problem

thanks in advance

Blow out the fans and heatsinks. You need to blow the stuff back the way it came in otherwise it just gets jammed in the heatsink fins. I have a Dell XPS1730 that needs blowing out several times a year. Its amazing how much dust comes out and how much cooler it runs after.

 

I've tried to blow out the fan.
there's a vent over the HDD, a vent over the memory and a vent underneath the sound ports.
there's what looks like a vent under the fan but I cant see any real holes in it.

please advise on proper blow out procedure.

 

I dont know your exact model, but you may have to take the laptop apart to clean it. Do you have any warranty?

 

Are you sure it's a heat issue ? I have the same exact laptop (i5 4GB) and my cores run all the way upto 149 F under full load. The room temperatures here in the SF valley can get upto 80F + and, while I was initially worried I confirmed that mobile CPUs run safe up until almost 100C (at which point they start showing problems). I think 124, 115 F are fairly normal temperatures for your CPU. Your area of concern might be something different such as the graphics driver or a hardware issue of some kind.

Here's a thread confirming what I mentioned earlier :

I did receive a driver update yesterday. That may fix the problem. I guess I can check by turning up the performance settings and see if it still BSODs.
