Many of us have extra parts which are gathering dust.
This may be an interesting solution to reuse an old socket 478 heat sink and fan.
Hear are some socket 478 coolers from my junk drawer a OCZ, CoolerMaster Aero and a standard Intel.
I used one of these Thermalright LGS775RM kits shown here
After installing on the motherboard, I noticed the brackets prevented installation of any of the 3 heat sinks. The problem was they prevented the heat sinks from seating on the cpu. In all fairness the kit is for Thermalright SI/XP-120 and XP90 models. To make them fit I used a hand grinder and ground off the 4 areas which were in the way. In the following pic I am holding an unmodified bracket over the finished one.
I installed the Cooler Master Aero after the bracket mod ...
Here it is again in the finished system. The e6300 cpu is running at 32C idle and up to 43C under load. I lowered the rpm of the fan to 2700 RPM from the 3900 RPM top speed.
