Asustor AS-HK1, M.2 Heatsinks for Flashstor FS67 Series/ FS68 Series/AS-T10G3

Works as expected. Perfectly fits NVMe only NAS. Although I believe it should be included in flashstor NAS

This heatsink is very small in profile but it fits perfect onto the M.2 SSD in my Flashstor FS68. It took less than 10 minute to install (including fishing for one lost screw inside the NAS) the heatsinks. Since they are from ASUSTOR they fit perfectly and because of the two screws they give the M.2 SSD's an additional security against loosening. In combination with the active heatsink (fan) they shout keep the heat down, even during hot summer times.

These were listed as necessary for the ASUSTOR F67 series for the M.2 SSDs I was getting but not for the F68 series. I went ahead and got them anyway assuming the heat management needs would be similar. Shipping took a few days longer on the heat sinks than the NAS, so I did try running my new ASUSTOR F6806X without the heat sinks and 3 drive temps were idling at 45-49°C and hitting 83°C with even a small stress test - well over the 70°C max operating temp listed on the drives. So I waited for what seemed like the longest weekend of the past year, and installed them within about 10 minutes of them getting delivered. Fired up the NAS and started moving larger and larger blocks of data. Now, the 3 drives idle at 39-43°C and the largest spike so far with a roughly 100GB write has been 48°C with 46°C typical. For such basic, low-profile, passive heat sinks, they do a great job at keeping the temperature steady - generally within 3°C of the at-rest temperature. If you're going to drop the cash on a NAS like this, getting these heat sinks is a no-brainer to protect that investment. (On a side note, the three 4TB cards I got came with what was supposedly a graphene layered label that was supposedly for heat management... That did absolutely nothing. Don't believe that if you see it advertised; get a real heat sink like these.)

Fits perfectly

OK, this heatsink should have been included with the asustor SSD NAS but Asus chose to nickel and dime customers and force customers to purchase heatsink. Well, the they fit perfectly and works well. You can't get 3rd party heatsink for Asus SSD NAS. So, this is basically your only option.

I have the FS607T populated with 6 TEAMGROUP MP44Q 4TB PCIe Gen4 x4 M.2 2280 I managed to reduce idle CPU temp about 10 C (from 50s to 40s) by replacing the oem thermal compound on the oem heatsink with Arctic MX-4. ssd idle temps seem constant at about 40 C no matter what. I tried: (1) with no heatsinks (oem graphene ssd labels in place) (2) with heatsinks (oem graphene ssd labels in place) (3) with heatsinks and Arctic MX-4 (heatsink thermal pads and oem graphene ssd labels removed) Not sure about heat transfer under heavy sustained load yet, but at least the heatsinks holds the ssds in place after the Flashtor clips break off.

Install was easy. These are very low profile, but better than nothing. I have not really noticed a significant drop in temps, but I do not exactly work the drives very hard. Single user NAS at the moment. It is mainly storage of common small files, like documents etc. Also stores photos, but they are not accessed more than a few times per week.

just in case i got this one and it seems to work. Not sure if it would also work without. I just got it as all my other devices have heatsins too.

Un peu cher, pour un bout d’aluminium Mais compatible à 100 %

Ben fatti ed efficaci nello svolgere il proprio compito. Prezzo un pò elevato !

Passt hervorragend zu meinem ASUSTOR Flashstor. Eine gute Lösung zur Wärmeableitung. Ich bin zufrieden.

Uitstekende & snelle NAS met uitsluitend M.2 NVMe SSD's. Wel opletten op de verschillende types van beschikbare CPU-lanes: de traagste zijn Gen3x1! Om minimum 2GBps te halen heb je dus maar 10 slots ipv 12. Mogelijkheid tot 10Gbps link aggregatie.

Two of the drives in my Asustor Flashstor Pro were running hot (>70C) under heavy load (like when scrubbing or rebuilding a RAID5 array). Heatsink solved the problem completely (now <60C under heavy load)
