MacBook A1181 White

I hava a old MacBook A1181 White (2007) which i recently turned into a media center connected to my HDTV. so far so good, it plays 1080p like a charm!

my only concern at the moment is temperature. when it plays full hd it stars to cook. also I have plex server running at all time, itunes running at all time. air server running at all time. so it gets a little warm when its on for a long while. at the moment i'm putting to sleep every time but I would prefer it to be on.

i took the display assembly completely off and i have raised the computer to allow more airflow. but not much difference


any tips, suggestions, deep thoughts?

 

if I keep the machine on with the services running:

exhaust fan: ~1798-1846rpm
HDD: 96-99*F
CPU: 142*F
Heatsink: A: 139*F
Heatsink: A: 142*F
Mem Bank: 126*F
Northbridge: 135*F

its warm, fans are nearly silent. = i guess its normal
------------------------------------------------------------

when i play 1080p videos:

exhaust fan: ~6270rpm
HDD: 98-99*F
CPU: 155*F
Heatsink: A: 139*F
Heatsink: A: 142*F
Mem Bank: 126*F
Northbridge: 135*F

fan is loud, and if i keep this for 2hr+ the machine is very HOT! i dont think its healthy... however I never had playback issues, lags or anything.
------------------------------------------------------------

so 13*F difference is making the fans go crazy

i might get a simple laptop cooler and see if that helps.

No audio will pass since its a DVI

so im using to feed my reciever: http://www.monoprice.com/products/p...=10229&cs_id=1022902&p_id=1557&seq=1&format=2

I get full 1080p with 5.1 DTS, DD & AAC
