Cooling advice needed.

[amiga4001]

It seems the temperature im my A4000 tower (elbox tower model) is getting to high for my ppc.

As soon as I close the tower the ppc freezes after a minute or 10 while playing wipeout or decoding mp3.
I already removed a 5 1/4 plastic cover on the frontside to let some fresh air in..but this is not enough.

If I close the tower fully even the PSU (antec quite new) blowes out very warm air after a hour or so.
This warming up of the psu has gone away since I removed the plastic cover of a 5 1/4 drive case.

Only if I keep the cover of the tower the ppc side has no problems with wipeout and mp3 decoding on the same time for several hours.
I removed the heatsink on the ppc and cleaned it... put new heatpaste on it(coolermaster paste)
Also the fan on the ppc is a 12V.... quite new.

Should I put a fan on the backplane of the tower to blow fresh air in?
Or should I buy even a better fan for the ppc which is now covered by a normal 12 V fan.
Or perhaps a fan in a 5 1/4 case in the front???

Any advice would be nice.

@robert17

Where did you purchased your heatsink?
Did you also placed a better fan on top of the heatsink?

Don't want to cut in the cases actually.
Was looking and there are some holes internal just after the plastic frontcover.
Maybe I'll put a fan there to suck air in.
Replaced the cyberstormppc fan with an adapter from 40mm to 60 mm fan nice..
Also put on a 80 fan on the backplane which sucks air out.
Now maybe the fan on the front and it should be right me think.
