Big 6 Pipe Dell 'Radiators' Make PCs Quieter  =)

For OptiPlex 'MT' (Mini Tower) PC Models:
GX620, 330, 740, 745, 755, 760, Etc.

Dell HeatSink Model = 'E521'
Shroud Models = J9761 & D9729 (? Copied Info. =)

 

Note: Shrouds are included within Dell OptiPlex 755 MT & Dell OptiPlex 760 MT PC cases so not needed unless there is some smaller incompatible shroud version installed I am not aware of. Be sure the shrouds are the same type pictured with 6 holes for the pipes, etc.
