i am looking at a liquid cooler made for a penteum 4 lga 775 socket. will this work on older ones too. in a dell deminsion 4550.
Any particular reason you need a liquid cooler?
The Corsair H50 will work on an LGA 775 board, but its not cheap.
i am looking at this one 109-LC1-003. made for lga775 socket wil it work on a mpga 478b?
Oh, i see what you mean now, i find it unlikely that it would work with socket 478, the intel brackets and holes have changed quite a bit since then and an LGA 775 mounting bracket isnt going to work on a non LGA 775 board.
