I took my completely apart when my started getting too hot, thought maybe had too much dust around heat sink, to my surprise it wasn't the case. problem was that both CPU and GPU shared the same heat sink but GPU didn't directly touched and pressed against it, there were around 3mm space between them filled with some foamy material, unlike CPU with was directly pressed against heat sink.
stupid HP hardware design made me to take it all apart including monitor side in order to even get to see heat sink.

other than this gpu cooling issue HPs are great.
don't know if HP managed to fix it in recent years. I bought mine in 2008
