Blue wire on cpu fan.

March 6, 2011 at 05:38:28
Specs: Windows 7, AMD Athlon 64 X2 Dual Core Processor 4600+ 2.40 GHz
My cpu fan which is from an ASUS X-Mars Lite (came with the heatsink) has three wires: red, black and blue. It has not been running at full speed since purchase, which causes the cpu to shut down during gaming due to overheating. Can I snip off the blue wire to stop the speed sensing or something? I really want it to run at full speed.

It's got nothing to do with the wire. Like I said in your other thread, you probably installed the heatsink incorrectly. Read the instructions:

I wouldn't cut the speed senor wire, that could stop the computer fro working at all. The BIOS will think that the fan has stopped altogether and cut the computer off as soon as it gets started.

You need to find out what is causing th overheating in the first place. What temperatures are you getting?

When you fitted the heat sink to the CPU did you use the correct amount of thermal paste between heat sink and CPU.

Are you sure it is not the graphics GPU that is overheating? Shutdown during gaming would indicate that as a possible problem.

There you go; two people have told you the same thing independently.

Heat-sinks are very fussy about being installed correctly.

Dude, it is due to gap between processor & heat sink.Use a thermal compound, also known as heat sink compound paste on the heat sink.
