Have been able to install the cooler on an Asus B 350M motherboard without an additional adapter or kit.

Ja, für AM4 ist alles dabei. Motherboard Compatibility Intel: Socket LGA 775/1150/1151/1155/1156/1366/2011/2011-3/2066 AMD: Socket AM2/AM2+/AM3/AM3+/AM4/FM1/FM2/FM2+ http://thermalright.com/product/macho-rev-b/ http://thermalright.com/backup/installation+2066/Macho%20RevB/Macho%20RevB.pdf

All I can say about the product digitec offers is that it is great, it doesn't make too much noise, you can add a second fan and with one it's not bad at all. I installed it on an i7 7700.

In my case, the distance from the mainboard to the cooler is just 28 mm, so that there is no room at all for RAM in one of the 4 RAM slots (even slimmer RAMs without coolers do not fit there). Depending on the design of the mainboard, the fan can also be mounted on the other side of the cooler (if there are no tall components on the mainboard blocking the space). Apart from that, I can highly recommend the cooler. It has good cooling performance and is very quiet. Many greetings Martin

no, it blows from left to right, you are looking for top down fans, c series from noctua is also recommended.

My mistake - I see it was included in the box contents

I think it's quite possible that you'll get a fan without an AM4 compatible socket (i.e. if you get a model that shipped before March). In this case, it should be possible to order a free upgrade kit directly from Thermalright. I did this about a month ago with my 6-month-old fan (costs 3 euros shipping) and received the parts in the mail after about 10 days.

I have the cooler on the ASUS Z170-A, here there are no problems with the RAM (a little tight for installation, but fits).

Yes, should not be a problem.
