CPU temp / fan problems.

April 9, 2013 at 07:39:36
Specs: Windows 7, Intel (R) Core (TM) i7-3820 CPU @ 3.6 GHz
Upon startup, my computer is making a few loud beeping noises followed by a black screen with the heading 'American Trends'. Following this is a list of my specs then two errors. They read as follows:

"CPU Fan Error"
"CPU Over Temperature Error"
Press F1 to run setup.

When I run setup (or BIOS mode), everything looks normal with the exception of the CPU temperature bar, which reads 86 degrees celsius. This is obviously excessive and I have no idea how to lower it.

The Fan Speeds read:
CHA_FAN1 RPM: 1016rpm
CHA_FAN2 RPM: 740rpm

Both bars are blue indicating no problem.

As a final note, originally the only issue was with the fan, (on startup it only read the CPU fan error line). I disregarded this and exited and continued to startup the computer. It was not untill I opened the game 'Far Cry 3' my whole computer froze on a black screen. I manually restarted the computer by holding the power button than pressing it again. These errors then occurred.

My computer is custom built, I don't have. the specific names of all the parts handy, apologies.

When is the last time you opened the case and cleaned out all of the dust? I would start with opening the case and using canned air to clear the dust out of all of the heat syncs and fans. Be sure to stick your finger in the fan so it doesnt spin out of control and damage the bearings while you're blowing it out.

Bios doesn't recognize CPU fan, only two case fans are recognized.
Open the side panel & make sure CPU fan is connected to the CPU fan header & not system fan header.
If the CPU fan is bad buy another inexpensive cooler or repair it if u can.
List complete system specs.

You know the real meaning of peace only if you have been through the war.

This may happen when you dont have anything installed in the fan header labeled CPU_FAN. It is required to boot. If you have one installed, leave the side case open and turn your computer on. Make sure it is spinning and working

Sounds like your fan failed as a result of dust or the other items mentioned above. The problem is you used the system with out a cooling fan which may have resulted in the Thermal Interface Material (TIM) drying and shrinking leading to the second error of your CPU over heating. I would try the first post, clean the fan, see if it spins up and if not replace the fan. If after this, you are still get the second error, try replacing the the TIM. If you are not sure on how to do this I would consult YouTube on how to clean and replace CPU TIM.
