saint19 said: The problem is that your mobo isn't prepared for a different cooler, so, those components around the socket can be a problem for install the cooler.
saint19 said: You will need a cooler more small almost similar to the stock cooler size.
saint19 said: TX3 maybe, I'm nor sure in recommend you a good cooler because of limitations space in your mobo.
saint19 said: Yeah sorry, forgot that your case is limited space.Check this page: http://www.frostytech.com/top5_lowprofile_heatsinks.cfmYou can find a lot of good low profile coolers than fit inside your case.
saint19 said: Yeah you are right, the capacitor next to the bottom left hole are the problem for install the cooler. My latest option would be buy a cheap used mobo and install the components and new cooler there.
saint19 said: Because Dell think cheap, so, they never think that in future you want better cooling.
