BE QUIET BK021 Dark Rock 4 135 mm Silent Wings Fan CPU Cooler - Black

BE QUIET BK021 Dark Rock 4 135 mm Silent Wings Fan CPU Cooler - Black

Q: Can I use this on a msi 970 gaming with a fx8350? Cheers

Hi, Thanks for the query. Yes, this should be compatible. Kind regards, Ebuyer Tech Support

Q: Would this cooler stop or restrict access to any of the memory slots on a msi mag b550 tomahawk (atx) (corsair vengeance lpx memory) ?

It will depend greatly on fan placement. I have a MSI B550 Carbon Wifi ATX board with Corsair Vengence RGB ram in slots 1 & 3. I have the cooler fan mounted on the right side (ram side) in a push configuration and sits over the 4th ram slot and you would not even fit low profile ram underneath. However if I moved the fan to the left of the cooler in a pull configuration then there would be enough room to populate all 4 slots. This is assuming that the Mag B550 is similar enough to the Carbon B550

Q: Does this come with a mount for the alder lake socket ?

Yes it does. It even came with an LGA1800 mounting bracket. I was surprised as far as I know it's not even announced yet.
