Can a 3 pin fan plug into 4 pin?

Apparently a 3-pin fan can plugdirectlyinto a 4-pin socket. Two of thepinsprovide power to the fan, the 3rd provides an RPMpulse tothe motherboard to read the speed. The 4th pin isfor PWMspeed control. If you plug a 4 pin fan into a3pin socket, the fan speed will be controlledbyvoltage and it'll still work.

How many watts does a Molex connector have?

You can combine 2 molex connectors into a 6pinpci-e connector that will provide 72 watts(thesewhere supplied in the box with my evga vid cards). Itwouldbe a bad idea to use a 6 pin to 8 pin aftermarketconnectorbecause it would mean that you aresupplying 75watts where you are supposed to supply150watts.

Will a 4 pin CPU connector work in a 8 pin socket?

The answer is yes. A 4-pin can be put,byitself, into an 8-pin CPU power socket andthemachine boot up and run. It will give it what poweritcan, and if the CPU draws more than that,itwill shut the system down. If it shuts down when youstartdoing intensive stuff, just underclock theCPU.
