What I haven't told you yet is that I have 2 MDD's.
1. A dual 1.42 Giga Designs Upgrade (no longer available & this will definately void your warranty). This Page.
And......
2. A standard Dual 1.25 from Apple (see Page 3)
I'll deal with the Giga Designs first as this was the first and easier of the two upgrades to do.
One of the base plates supplied with the kit (see picture) fitted this perfectly but needs a copper shim (details on PAGE 9).
I don't own a milling machine but I know a man that does.......
2 finger tapping days later having drawn up carefully my copper shim and were back in business.
The shim covers both processors and needs the usual silver paste. This is held in position by the sticky surround on the Giga and then more silver paste between this & the pump. |
|
The thickness of the shim needs to be 8mm and needs to run the length of the processors, widening in the middle to contact with the full width of the pump base (above left).The purpose of the shim is to make contact with the processors & the copper base of the pump. It acts in a similar way to the heat spreaders you see on Athlon 64's & P4's.
Having run this system for some time using the fan supplied with the Aquagate there was a slight whine from the fan, even though it is adjustable. The standard Giga fan which is slim is the ideal thickness to fit on the hard drive side of the radiator & is quiet. To cut a long story short I opted to fit this fan and an identical fan on the opposite side, sandwiching the rad between the two (see above).
Two small 60mm fans were conveniently left in position, from a previous fan upgrade - see MDD Fan Fitting Page above. These also help with heat extraction although only run at 5v to help keep the noise down.
So all in all works well! |

Giga Dual 1.42, currently running happily and clocked at 1.5 Gig & at a temp of around 33 degrees C.
Soon we'll see how high the venerable 7455B processor will go!
On to the next page an Apple dual 1.25 to be watercooled......
