Simple QUESTION for those who know the answer! The fan on my processor stopped working. The original one had a three wire connection and would switch itself off and on, eventually just off, which is why I REPLACED it. I found another one that fitted but had a four wire connection to a power lead inside the computer. This one just runs constantly. Is this okay or do I need to get a three wire one as PER the original?
GRASSHOPPER seeks enlightenment! Thanks of any replies. if this is the 4pin connector you are talking about you can keep it on there,however, it will be on all the time at 100% speed. if you get a fan with this kind of connector, you will be able to hook up the fan to the CPU fan slot on the motherboard. it will then RUN at variable speeds depending on the CPU temp, assuming your motherboard supports this feature.Yes, not as elegant as fan speed based on temperature; however, it's cooling the most important element of the computer, so from that standpoint, 100% isn't bad.

Those members who are better informed will explain further, and correct the error of my ways, which is always welcome...Thanks for the info. I will keep the new fan on there for a while and get a new 3 wire one after Easter.
