Since the nortbridge on the Gigabyte GA-MA78GM-S2H is so powerful with its integrated GPU you would think that Gigabyte had placed a desent heatsink to cool it down. But many owners of this HK are conserned that the temperatures of the northbridge are too high. I tried to put my finger down on the HS but after a second i had to retreat and I saw a clear mark at my finger for where the fins are. And that was when the PC just idled and I looked at the BIOS-menus! So, in advance, I bought a Thermalright HR-05/IFX to help with the cooling..
So here are my tools for the job. It’s the cooler in the brown ugly-but-somewhat-proffesional-looking box. A bunch of cotton-buds and Artic Cooling cleaner kit
The cooler came with good instructions and many bits and pieces:
- Three types of springs
- 2 pairs of washers
- a pair of J-hooks
- a pair of screws
- a pair of spring-clips
- two nuts
- a syringe with some thermal compound
- a foam spacer
- a pair of fasteners to a 80mm fan
First step: Remove the old HS. Just use your fingers or a nose-pliers on the back of the MB to loosen the plugs that hold the HS. Then twist the HS a tiny bit to either side, and lift up.
Second step: Rinse off the old thermal compound.
Third step: Use the pad that was included with the new HS. This was too big for the chipset so I had to cut it to fit. I used the old HS for measurements.
Fourth step: Apply some thermal compund and mount the HS. Sounds easy right? Well, first I had to remove the CPU-cooler – it was to much in the way.. Then I put the screws with the washers in place. The spring that I should have used wasn’t long enough to reach to the holes, so I had to use the tallest, the one that normaly is used for the J-hooks, so the screws was a bit short. They weren’t too short, I just had to use some force to hold the spring down so I could screw the nut on. It wasn’t easy, but doable.. Here are some finishing shots:
As you see the PCI-e 1x slot is useless, and to use a VGA-card with passive cooling on the back could be a challenge.. It’s a shame, but it’s not a problem for me at the present time..
