Hey there. I just got a second nvme for my pironman 5 max. I originally had an arctic nvme cooler on the first drive and already have a second on order. I found that with the heatsink on the one drive, I cannot insert the second drive into the nvme slot; they’re just a tiny bit too close together. Is there a different nvme heatsink that’s a narrower profile that’ll work with both drives? Or did you modify the heatsink so 2 will fit side by side? Thanks guys 
It is possible that the larger size of your Arctic NVMe heatsink is occupying some of the space allocated for the other SSD, preventing SSD2 from being installed properly.
We recommend purchasing a heatsink or heat sink that is the same size as your SSD.
hi, can you please share some heatsinks for small sized nvme 2230 and/or others probably with link or company names?
i am looking for them in India..
also, isn’t the pcie interface pcie 3.0? so nvme 990 pro or others work in compatibility with 3.0?
For the heatsink: You can search for an “M.2 2230 heatsink” directly on Amazon.
Example search: Amazon.com : m2 2230 heat sink
Regarding PCIe compatibility: The Raspberry Pi’s PCIe interface supports PCIe 3.0. However, the Pironman 5 Max Dual NVMe uses a PCIe 2.0 switch, which means it is limited to PCIe 2.0 speeds.
The problem is that the two nvme drives are flush to eachother; there’s not 2mm of space between them to allow for a m.2 cooler on either drive when two are installed, let alone both. I was wondering if anyone found a cooler that does work, because much like the Arctic cooler, every m.2 heatsink I’m finding encases the m.2 drive, which means it won’t fit.
That is correct. It is indeed incompatible for installing the Arctic heatsink.
It is recommended that you install a regular heatsink.
The following product is for your reference:
