I do not believe the thread is getting "derailed" by including the experience of overheating. Regardless, I'll gather up all the related posts and create a new thread. I'll post the new thread link here when I'm done.

EDIT: Sorry for the delay. Here's the link. Please click HERE.

I wonder which way the fan is blowing? My gut feeling is that it is sucking air in and blowing it over the main chip and also into the hard drive with the output passing the power supply and out. This makes more sense to me than the fan layout of the 622/722s.

Can anyone confirm my suspicion about which way the fan is blowing?


If the fan isn't wired backwards, the picture indicates that the fan is blowing air into the case. However, because there appears to be a lack of a notch in the hard drive tray, a lot of the air flow is probably getting pushed back towards the fan, creating a eddy. This would not be good.

Are you getting this from pictures or have you actually opened up a hopper?

I'm getting it from the way that the fan is attached to the chassis in the picture. Fans usually blow air out from the same side the DC wires come out of the motor. In this case, the wires are towards the inside. So, as long as the polarity of the fan is correct, the fan represents the intake.

I wouldn't relay to wiring of a fun; each fun had marks - direction of rotation and air flow. And some [smart decision] PCBA has silkscreen showing same marks for proper install of the fun. I've seen wrong positioned fun inside of TR-50 [DTVpal DVR].

Elsewhere on the cabinet the paper didn't stay in place.

Thanks,
I guess that is proof that the fan sucks (the air in), which would be logical as you would want the air to exit over the power supply and not enter into the cabinet over the power supply.
