Need some help fast

Ok i was repairing my brothers Xbox its a 1st gen xbox so i really didn't have much hope but i got it to work but there is one problem.

The fan is blowing the air out the back of the xbox not towards the heatsinks. Its blowing air out the back and the Xbox will 2 red ring (overheat) in like 30 seconds. i don't know if this is normal for a 1st gen xbox but u don't know what to do? any help is appreciated thanks.

That sounds right it should pull the air across the heatsinks and out the back.

Ok its really hard to explain but like if i put my hand near the heatsink i cant feel any air being pulled through or anything?

If the box powers off within 30 seconds the heatsinks are not good positioned OR
the thermalpaste is too thick onto the chips.

Ok now its not overheating and turning off i can feel air going through the xbox but it stops loading the the xbox symbol comes up i guess there is something wrong with the gpu.

EDIT: got the secondary Error code 0011

E05: CPU over heating - If you are receiving this error after disassembling your console make sure to all 8 of the heatsinc screws are tightened securely to the board/heatsink holes.
