Cpu fan and optical drive fav spinning at full speed.
Well good news I have one of my macs up and running with the new ssd drive in it. It took a new graphics card, and new backlight card, and I had to switch out the motherboard, butt it think the original board was fine. My temp cables set up. I used a lcd temp sensor wire and taped it on my ssd drive. On start up. My system is using mavericks and starts up normally but the CPU and optical drive fans are very noisy from the get go. I checked my speeds and temp and all seam way low enough. Funny thing is it says my cpu fan is 0 rmp and I know it is not it is the one making the. Most noise. I know I can enter a command in the terminal to reset these fans to a lower rpm, butt I want a more permanent fix. Can some one help?
Это хороший вопрос?

Is it always that your mac boots up with loud fan noise? Or it happens randomly?

Hey it is always loud as soon as I turn it in till about a minute after it goes to sleep. I have installed smc it says my cpu is at 0 rpm. I am sertain it is at full speed.
Also about the shorting the hdd temp sensor. I have read some posts that say to do that and some that say you don't kneed to.
In any case would not having a hdd sensor cable cause the optical drive and cpu fan to spin at full speed?

Also my mac doesn't feel warm at all actually kind of cool and my temps say they are all under 50 deg c

At first start up smc says odd 1000 rpm, hdd 2502 rpm, and cpu 0 rpm. Hdd temp is 22 deg c, odd temp is 22 deg c, and cpu is at 22 deg c.
