I posted about a BSoD episode I had on Monday.(Sorry it won't let me link back as this is only my 5th post here) As I mention in that thread, There have been no other Issues. Just a while ago I had to crawl under my computer desk because I dropped a cigarette lighter. While I was under there I noticed that my CPU Fan seemed to be blowing warmer than usual air out the back of my computer which is unusual.

I installed SpeedFan and here are the readings as of now on speed fan

Ambient 38C
Remote1 38C
Remote2 119C
HDD 39C
Core 31C

I made the Remote 2 bold because I did the conversion from Fahrenheit to Celsius and the reading in Fahrenheit is almost 240! degrees..When I increase the speed on speed Remote1 the fan doesn't get faster, however when I Increase the speed on Remote2 I can hear the speed on the CPU fan increase. I'm guessing that Remote1 is the power supply fan on the rear of my PC?

If this is the case then why does the speed on the power supply not increase or decrease when I toggle the settings on Fanspeed?

Lastly, Could this have been the cause of my BSoD as contained in the link I posted above?

Hi charlie

Overheating can definitely cause a BSOD. Power supply issues / driver issues / faulty RAM or Motherboard / processor / conflicting devices are other causes. BSODs occur to prevent any further hardware damage as the system believes this might well happen if it allows things to proceed. As to whether what you did or overheating caused your specific BSOD, I'm unable to say. If it occurs again, post a few dumps and we'll have a look at them.

Thanks Spyder. As I said in my other thread "Unusual BSoD Incident" The next morning after the BSOD, i was able to boot up as normal.

I did Memtest--no Errors
There were no errors in my device manager
I made sure all my drivers and software were up to date and they were except for Internet Explorer (I never use IE, I always use firefox)

Is there a tool that I can use to test my CPU.& Motherboard
and what can you tell me about the results I got from Speedfan?

Also can dust inside the CPU and inside the fans cause overheating?

Hi charlie

The Remote1 and Remote2 identify remote probes that are connected to hardware on the computer. To identify the type of hardware on each of the Remotes you have to go into the BIOS (press Del on startup) and compare the temperature settings given by SpeedFan to the hardware devices identified by those temperatures. I don't think you have anything to worry about with those temperatures.

To find the CPU Temp, let your PC idle for a few minutes so that the temps drop ... then go to 100% usage for a while .... the temperature that rises fastest is your CPU temperature. Not sure of how to test the Motherboard .... HDD = Hard Disk and Core = Graphics card as far as I know .... everything seems fine in terms of temperatures.

Thanks Spyder. I will restart and go into bios (it's F1 on my computer) and find those settings, I do know that I need to get some dust out of my case...I'm getting some canned air when I go to the store later today

I went into BIOS and it shows my system fan reporting as 0 RPM. I know thats not right because I see the fan turning....it showed my CPU Fan as 2348 RPM.

Try using Everest to check your system whenever you need. It gives you temperatures of the CPU, Graphics Card, and HD .... Also tells you the speeds of the cooling fans installed. Much more comprehensive program than SpeedFan in my opinion.

You can get it here .... http://www.softpedia.com/get/System/System-Info/Everest-Home-Edition.shtml .... let me know what you think.
