MaxUpgrades is offering the $39.99
for users who want to add Fully Buffered Memory (FBM) modules to their Mac Pros and want to make sure they’re properly cooled.
Memory purchased through the Apple Store and select Mac-friendly vendors arrives ready to install in the Mac Pro, but some memory purchased through third parties may not include sufficient cooling technology to allow the memory to work within Apple’s spec for FBM memory in the Mac Pro. The MaxSink fixes that by providing an aluminum heatsink to dissipate heat, which keeps the temperature of the memory module under operating limits.
The MaxSink features thermal conductive heat pads to optimize heat transfer, and uses a step design to accommodate thickness variation in chips.
