Can I use my old core 2 duo (E4300) heatsink for my upgrade core 2 quad (Q9450) 45nm bought in eom version ?
It seems like the the E4300 original heatsink fan from intel is a 12volts 0.2A
while i guess the Q9450 should be provided with a 12Volt 0.6A, does it matters ?
in any case both heatsink unit look very similar at a first glimpse
You can definitely use your e4300 heatsink on the q9450. The q9450 does produce more heat (95W vs the e4300s 65W) so I would check the load temps once you have it installed. You want to stay away from 71.4°C on the q9450.
