Hello everyone,
I own a Dell XPS studio 8100 series desktop w /an I7 chip and Windows 7 64-bit and believe there is a problem with the PC's fan. The other day I noticed the PC was very quiet, there was no sound coming from the PC at all, I thought the PC had gone into sleep mode but it hadn't, the system was active. I downloaded SpeedFan, and the output is listed below:
Fan 1:912 RPM
Fan2: 925 RPM
Temp1:261 F
Temp2: 72F
Temp3: -53F
I'm not familiar with this application, I'm assuming Temp1 is the CPUs temperature? I googled normal operating temperature for an Intel I7 chip and it's listed at 149°F under a full load. A friend checked the PC and said he could feel air blowing out of the back (disabled, can't do it myself) near the fan but 912 RPM seems very slow. I followed the instructions at

and was able to increase the fan speed to 4470 RPM and the PC now sounds like it used to, maybe a bit louder. Thing is, the Temp1 reading is still 261°F, and the core0 through core3 temperatures are changing from 93°F to 105°F. I believe the core zero temperature reached as high as 120°F before I increased the fan speed. So, my question is how did my fan speed get changed on its own? This type of thing never happened in the 10 years since I've owned this PC. What are the correct case and CPU fan speeds for this PC? I tried searching Google but couldn't find it listed. I used SpeedFan to set both fan1 and fan2 to 100% speed, is that okay for them to be running that speed 24/7? Thanks in advance for any info you can provide!
