I bought 2 years ago an HTPC with an AOpen Box which included a Radeon HD5450 graphics card with no fan but a passive cooling system. Now the HTPC crashes after 20 minutes or so.
Doing my own research I've noticed that the graphics card reaches more than 100º C, not playing, not even watching videos. Just with the MS Windows desktop started it reaches such temperatures and shortly after the computer crashes, starting up again after a variable period of time (I guess after returning to safe temperatures).
I guess there's a problem with the card cooling system, and maybe I should buy a new one. However most of new cards are too tall for this HTPC box (about 9 CM toll, so it needs about 8 cm or less for the card) .
Then my question is, any suggestion for a new card short enough to fit in my HTPC? or s tehre any kind of solution for overheating issue?
Thanks in advance
