The short version:
If you build your system using low speed fans (such as the Enermax Marathon 120mm, which runs at 900 RPM) as either CPU or case fans your system may not boot due to a 'detected under speed or no fan'.
The long version:
I stumbled across this nugget in a review of the ASUS M2N32-SLI Deluxe Wireless mobo at NewEgg.com. I would credit the author but I could not find a name on the review.
His mention of a First Boot problem caught my eye and the symptoms were EXACTLY what I am experiencing with my new(now old?) build. I get fans and LEDs, but no beep, no post, and no video.
Since I have an Enermax Marathon 120mm fan mounted on a Thermalright Ultra-120 eXtreme cooler and plugged into my CPU FAN socket I hoped that this might be my problem. No such luck. I tried plugging in a high speed(read noisy) fan but it didn't change anything.
Continue only if you are REALLY bored and have nothing else to read:
I say 'new(now old?)' build because I put it together last September, it failed First Boot, and I've only recently begun to poke at it again.
I know that 'proper diagnostic procedure' is to pull out the mobo and try it outside the case, but for some reason my twisted mind refuses to accept that. After the effort invested in getting it all assembled I just can't bring myself to pull it apart. This is my third build, what the hell is my problem with undoing a few plugs and screws?!
Since the system is now six months old (that's 8 dog years or 80 computer years?) I'm considering just replacing/upgrading the CPU with a quad core unit and new matching mobo.
I know it's crazy, but somehow disassembling the whole system to do an upgrade(to a system that has never functioned :) ) is not as repulsive as tearing it apart to test components.
