thing is... when i've got my I-N73HD i tested it with my friend's p4 and the HSF didnt spin, but it works fine on his intel mobo so it wasnt the fan, then i installed my old p4 and the fan spined just fine so i thought wtf!? my friends HSF is a little bugger! but now that i've got my e8400 the stupid fan isnt working either but it spins just fine on my friends intel mobo... and i really dont know what to do now... because the issue its not in the fan!!
Check your bios for smart fan. Chances are, it set to turn on when it reaches a specified temp, say.. 55C. Its just a feature to make your system run quiet.
thats what i thought but i waited till it got over 70C and the fan never woke up, the target temps are in like 50C but when it reached and overcome this temp it just stayed idle... i tryed disabling it too so it spins at 100% but it didnt worked either, i tested my CPU/HSF on my friend's intel mobo and it spins just fine so i know the HSF works it just wont wake on my mobo
so... the c2d HSF had a little difference in the wiring, while the old p4 HSF has a blue, green, black, yellow wiring in both the fan-end and the mobo-end, the c2d HSF has blue, green, yellow, black in the fan-end and a blue, green, black, yellow wiring in the mobo-end so that confused me a bit... so i tried to put the wiring as in the old p4 HSF turn the pc on and then... bah nothing happened, so i got really frustrated since i put my hopes in the wiring issue, so anyway i bought a Coolermaster Hyper TX2 Heatsink to get rid of the doubt of have gotten a dead stock HSF, i plugged in and turn the pc on... again nothing happened so i thought "i ruined the darn CPUFAN1 connector with the wiring experiment, ill try the SYSFAN" but the stupid HSF didnt worked either and then i was really tempted to slam my pc on the floor, i calmed down and plugged the hyper on the AUX1 connector (after i tried turn the FANEQ control off for both the CPUFAN and SYSFAN in the bios) and then the hyper started spinning (at full speed and noise obviously) but i got really upset since neither the CPUFAN1 or SYSFAN connectors work anymore and i really dont know why.
Now i have a really cool system (since the hyper is always at full speed) and a lot of doubts and thoughts of what did actually happend.
thx (NOT "everybody" just Grimmy ) for all the replies.
