Installation (continued):
I had some issues with the
Thermalright HR-05 IFX SLI chipset cooler using the stock hardware. Since the M3 nuts were not open at the top, they would only screw down to a certain point. The cooler did not feel totally secure, and I could wobble and twist it all around, as shown below.
To fix the issue I used two other washers, (not included with the product) and replaced the rubber washers underneath the motherboard and put another under each M3 nut. This held the chipset cooler down much better; it will still twist with some force, but not like before without the larger washers.
With the Thermalright HR-05 IFX SLI secured to the nForce4 chipset, it was time to install my SLI setup again. If you take a look in the next two pictures you can see the new cooler's base fits under the top PCI-E card and the heat pipes and fins have enough distance from the video card. But, if you look closely you might notice a potential problem.
The problem is that the top nut can actually be touching the top video card. There is a chip right above it and some solder joints right next to this screw. Regardless of the beefed up washers this could be an issue, but some simple electrical tape wrapped around the nut will prevent any shorting.
Before testing the cooling performance of the Thermalright HR-05 IFX SLI, I plugged in all of the necessary connections, one being the 4 pin connector on the motherboard right above the nForce4 chipset. It is rather tight with the new cooler, but it does fit (it just rubs on the fins a little while plugging it in). Obviously, there is no chance to fit a 80mm fan on the cooler. I put a Enermax Enlobal 120mm fan blowing air in the direction of the cooler, as shown in the bottom right image.
