Q: The mounting screws for the device seem to be too short to secure the device onto my system, what should I do?

A: For computer cases that have a thick metal sheet, the included mounting screws (M3*2.5L) may not fully secure the device. Please use longer screws (M3*4L) to secure the device or contact us at tech@icydock.com for replacement screws.

Q: Can I replace the cooling fan attached to the device? Will doing that void the warranty?

A:The cooling fan we used has been thoroughly tested with the drive enclosure to ensure it functions properly and supports the fan speed control (for select models). Therefore, we suggest our customers keep the original fan for the best result. However, we understand the stock fan may not be suitable for all the applications, so we elected to honor the warranty when 3rd party fan is using. The warranty may void if the 3rd party fan causes electrical damage to the device, though.

Q:  Which specification should I check before buying the 3rd party cooling fan?

A:The following information is the fan specification requirement and compatible fan models for MB038SP-B


Fan Dimension (LxWxH) 40 x 40 x 10mm 40 x 40 x 20mm
