The Qiaosibo HX7280, with its 160mm height, requires careful consideration regarding its compatibility with other components in the system, particularly when it comes to memory and motherboard heatsinks. During installation, it has been observed that the height of the memory modules or the heatsink on the motherboard can influence how the fans need to be positioned.

For instance, if a 12cm fan is mounted at the front of the HX7280, the maximum height for the memory modules is limited to 44mm. On the other hand, using a 14cm fan at the front reduces this limit even further, allowing for memory modules with a height of only up to 24mm. This limitation is crucial for ensuring that the fan does not interfere with the memory. Similarly, the compatibility of the rear fan is affected by these height constraints.

In the specific cases of the ASROCK Z790 TAICHI and ASROCK B650E TAICHI motherboards used in the test setups, it was found that to install a 14cm fan at the rear normally, the fan’s position needed to be raised by about 15mm. This adjustment effectively increases the total height requirement to 175mm. Therefore, users need to verify the height clearance of their PC chassis before selecting this cooler, to ensure it fits without any issues.

Given these considerations, users should carefully evaluate their system’s internal space, particularly the clearance around the CPU socket and the height of the memory modules, to ensure that the HX7280 can be installed without hindering other components. This is especially important for those using motherboards with taller memory modules or extensive heatsinks.
