Corsair H55 on a 6950

I have just (successfully) overlcoked a 6950 with a H55 water cooler.

This has been done before with the higher model coolers but i though i would give it a try with the H55.

What you need:

Corsair H55 Hydro cooler
Your GPU with simular mounting holes
A s**t load of cable ties (just in case)
Additional (quiet) 120mm fan
Nail varnish remover (to remove the old tim!)
Not to be tired!

Before the water cooler was added, the clocks were 900/1375. With the cooler it has reached 980/1375; 80mhz over a 6970 lightning.

Here are my images and annotation:

Above is the H55 water cooler (£49.99 PC World) with some Akasa Thermal Tape (£6.99 Maplins) and a 3 pin fan adaptor (£3.99 Maplins).

Above is my MSI r6950/70 with the H55 boxed and ready to open.

Here is the water cooler un-boxed; I was surprised at the size.

Bellow is the Twin Frozor II MSI cooler which has done a fantastic job so far at cooling! (You only need to remove the back 4 screws to remove the cooler!)

Above is the fully cleaned chip of the card which was cleaned with nail varnish remover.

As you can see I have kept the memory cooler on and later added some heat sinks for extra thermal output.

I added the cooler on carefully, ensuring the cable ties could firstly fit through the socket holes of the card. I then tied them tight making sure that the sink was flush with the chip. (You need to make sure you tie to main cable holding the other around above the middle of the block, otherwise it will slip off!)

I have added push/pull fans as this seems to be the best solution.

And finally, installed in the case (looking good! Besides the tidying of cables!)

The load temps were 40c idle / 75c load with the MSI Twin Frozor II. Its now running 30c idle and 50c load with the H55.

Any questions, let me know :cool:.
