SilenX IXG-80HA2 Review

» Discuss this article (4)


I installed the IXG-80HA2 onto a Sapphire HD 4850 video card using the included thermal paste. With experience, replacing the factory cooling solution with an aftermarket product is a relatively uneventful process. As with most tasks, the first time can be a little frightening but don't fret. The installation guide is well written and shepherds you through the process step by step. 

After powering down my computer, I removed the video card from the motherboard. This consisted of removing the back panel screw and detaching the six pin power supply connection. I placed the card on a clean, flat desk and gave it a quick inspection to locate the mounting screws and fan connection. In this case, I removed the four screws that secured the reference design heatsink to the PCB and disconnected the two pin fan cable. You can see the 4850 graphics processor is relatively small and is surrounded by eight black memory chips. I suggest cleaning off the old thermal paste with ArctiClean before adding a new coat and installing the IXG-80HA2. 











Moving on to the next step, I mounted the included RAM heatsinks. I was only able to use four heatsinks as the rest of the memory chips are underneath the main heatsink and come in contact with the copper heatpipes. I placed thermal pads on these chips. I would suggest doing a couple of test mounts to make sure you are using the right amount of memory heatsinks.    



After spreading thermal paste over the graphics chip, I lined up the holes on the cooler with the ones on the video card. Using the included O-rings, bolts, and screws, I installed the GPU heatsink with no problems. Only after installing the card into the system did I find an issue. Once you've connected the 6-pin PCI-e power connector to the card, it is difficult to remove it due to the cooler's length. I had to use a screwdriver to squeeze the release tab on the power connector but it's not a deal killer in any sense, just an inconvenience. 



Even with its massive size, the videocard and SilenX cooler combo remains a dual slot solution. The IXG-80HA2 is actually a couple of inches longer than the 4850 and gives the card an intimidating look.
