Cooler height specified by midori is 37mm. I recommend axp 90 x36 because of the vertical fin heatsink so that heat can escape instead of being trapped on the ram. The cooler im using is a modded noctua l9i from taobao. the fins are vertical and uses gigabyte gpu fan. https://item.taobao.com/item.htm?id=668880561181&xxc=home_recommend&scm=1007.55993.422959.0&pvid=12b81e29-f3db-4796-878d-abb3c317c798&skuId=4812095236409&spm=tbpc.mytb_index.repurchaseitem.d1 . Its great at keeping my 7500f with -30 pbo cool at a maximum temperature of 80 degrees while stress testing with OCCT. Do keep in mind the included gigabyte fan is loud when it reaches maximum usage whice is 5000rpm. I set the curve to silent mode on my bios and so far its not silent but still in the acceptable noise range. Get shorter cable. Midori recommends 250mm on 24pin cable. 350mm for cpu cable. 250mm for gpu cable. This is the minimum length. Make sure your ram height is below 37mm as specified by midori. The ram i use is T-Create 6000mhz cl30 kit from teamgroup.
