I have a Dell Optiplex 755 and it has this large plastic cover that holds the cpu heat sink and directs airflow from the fan over the heat sink. The problem I have is that I want to put an nvidia 460 in and the card is too wide, it won't fit with the plastic cover.
Anyone changed the heat sink/cpu cooler on this model or at least have some suggestions?
The PSU was upgraded to a 500w awhile ago, I forget the manufactor so that isn't an issue.
I currently have a 8800GT and it is having problems which is why I want to upgrade. If I can just find a decent alternate CPU cooler so I can ditch the big plastic cover I am golden. It will be a tight fit but it will work, I only need about 1/4" more space.
There are no alternate Dell HSFs. You can't use an off the shelf replacement, only Dell HSFs. You might be able to modify the shroud and HSF you have with a dremel tool to creat the clearance needed. Or, you can attempt to find a smaller Dell solution at a website like txcesssurplus.com. Good luck!
