The cpu fan is a 4-pin connect system. The fan sits atop the cpu and has 4 plastic pins that go through the matching holes in the mobo, when you push down on the black plunger running down the center of these pins it is supposed to push the pin through the hole, then expand the little barbed end of the pin once it is through the hole and secure the fan to mobo and make it snug to the cpu (so heat sink is in contact with the thermal paste and surface of the cpu).
It is a mickey-mouse setup - some of the pins will not snap at all and others go in but then pop loose. I've tried adjusting the pins - some are in and some out, so for the time being I have the rig laying on its side with the mobo and fan facing up instead of in their normal position which would be sideways when the case is in its upright position. Using gravity to keep things where they belong until I can fix this annoyingingly simple and stupid problem.
Most of the 775 fans use this pin system... my fan is a Thermaltake 775D with heat pipes on the side. Seems like a good fan except for dorky hardware.
This has been a long and hair raising process of building this system... all along the "LCD Poster" - a little thing that looks like a tiny digital clock with a wire that connects to the mobo - was apparently the culprit. Connected I get no post, not even a beep - take it out and all is well. So far I haven't found a word in the manual that tells what this dingus is supposed to tell you. So far I've resisted the urge to smash the demonic doo-dad to smitherines.
Thanks again for the support and help to all-a-y'all (pardon the southern dialect)
