I recently opened my computer and noticed that my CPU fan is no longer working. I am not sure if it is the fan itself, or the power slot on the motherboard. I don't have any other problems with the motherboard, so its probably the former. Regardless, I have been running my computer with no CPU fan for somewhere between 1 day and around 6 months. It seems to run just fine, and when I first noticed the problem, it had been running for several hours, but the CPU was only at around 40 C, which is well short of the maximum temperature listed for my cpu here: The Heatsink Guide: Maximum CPU temperature
I have an Athlon X2, and a pure copper heatsink (the heatsink fan is what does not work, here is what I have: Newegg.com - ZALMAN CNPS7700-CU 120mm 2 Ball Cooling Fan - CPU Fans & Heatsinks
), and 3 other working case fans for circulation. Anyway, the question is: what are the implications of continuing to run without a CPU fan? I have never heard of a desktop PC with no CPU fan, but then again I don't have that much experience with hardware. Also, since the case fans are still working, will the CPU fan plug fit on to case fan pins on the motherboard? Will the fan work (assuming the motherboard is the problem) if I do that, or will that cause problems? I would prefer to sacrifice one of the case fans if it means getting my CPU fan working. This feels like a really bad question, and the obvious answer is to just get a new motherboard or fan, but I think I will be buying a new computer within the next year, so I prefer not to buy anything I don't have to. Since the machine seems to work fine....
