Q: Can you recommend an add-on card that works with MB720MK-B V2?
A: The following add-on cards are compatible with MB720MK-B V2. We highly recommend using the official cable for the best compatibility.
We are currently certifying our NVMe enclosure with the major add-on card manufacturers. We will be adding compatible add-on cards to the list.
You can click here to report a compatible add-on card/cable. If you want to check the compatibility of add-on card(s) that are not on the list, please click here.
Q: The system does not detect the M.2 SSD I installed in the ICY DOCK enclosure. What should I do?
A: Since the M.2 SSD is not designed for hot-swapping, we highly recommend powering off the device/system before inserting or removing an M.2 SSD. If the system is still unable to detect the drive, follow the steps below to scan for new hardware manually:
Windows 11 / Windows 10 / Windows 8 – In the search box on the taskbar, type device manager, and click it from the menu. Once the device manager window pops up, right-click on the disk drive icon, and click scan for hardware changes.
Windows 7 – Right-click on the computer icon on the desktop, select properties, click device manager, right-click on the disk drive icon and then click scan for hardware changes.
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 MB720M2K-B V2
| Fan Dimension (LxWxH) | 40 x 40 x 10mm | 40 x 40 x 20mm |
| Connector Type | 3 Pin Wafer | |
| Rated Voltage (VDC) | 12V DC | |
| Rated Current (A) | < 0.12A (127mA) | |
| Screw Specification | Phillips Flat Head - M3 x 15mm - Steel (Not Included) |
Phillips Flat Head - M3 x 25mm – Steel (Came with stock fan) |
Compatible fan models
(without test, use it at your own risk)
Q: I'm having the difficulties closing the lid of the drive tray and unable to insert the drive tray all the way to the drive enclosure after placing the M.2 SSD onto the drive tray.
A: Make sure to lock the M.2 SSD with the adjustable M.2 locker. The tray lid will not close properly if the M.2 locker is not fully secured. If you are having difficulty secure the M.2 locker or close the cover, the M.2 SSD you are using may not follow the standard M.2 SSD thickness, which is less than 1.5mm height for each side with a total height that does not exceed 3.8mm. Using the M.2 SSD with non-standard thickness will cause improper tension on the M.2 locker and tray lid and make the M.2 connector misaligned. If you are having issues inserting the drive tray to the enclosure, please stop the operation immediately and check the drive thickness to ensure it follows the standard M.2 SSD thickness - less than 1.5mm height for each side and less than 3.8mm for total height.
Note: Some M.2 SSD uses a metal heat dissipation sticker that causes each side's thickness more than the 1.5mm. Remove the sticker will solve the problem, but do it at your own risk (might void the warranty of SSD)
ICY DOCK enclosure is design to be compatible with M.2 SSD that has standard thickness. We highly recommend checking the drive thickness before purchase, and please refer to the incompatible M.2 SSD list below for further information:

Please contact tech@icydock.com if the problem persists so we can resolve the issue as soon as possible.

Q: I feel that the drive tray's upper and lower metal spring is stuck when inserting the drive tray. What should I do?
A: Remove the drive tray from the enclosure and reinsert the tray without putting excessive pressure on the metal mesh sheet in front of the tray. Excessive force on the front metal mesh sheet may bend the top and bottom metal spring, causing difficulties when inserting the drive tray. Therefore, please do not forcingly insert the drive tray when this happens as it may cause damage to the metal spring.

| Please DO NOT put excessive pressure on the metal mesh sheet as shown |
