motherboard heatsink blocks cpu fan heatsink

Parts:

Mobo: Asus ROG Strix X570-I Gaming Mini ITX AM4 Motherboard

Cooler: Noctua NH-L9i 33.84 CFM CPU Cooler (with adapter bracket for AM4)

 

This small bit of the motherboard cooling system makes it impossible for me to mount my CPU cooler. I've tried pushing it in from the side to no avail, and the screws are too short to even get it on there, though the piece would still be there.

 

What's my best course of action? I can take off the piece of the motherboard heatsink I think, but I've heard that you shouldn't leave it off. I think it's made of metal, so could it be possible to remove it and sand off the little bit I need for clearance? I really am stumped (and frustrated at the design). Thanks in advance.

Yeah it's metal. Friend of mine had a heat sink that was too obstructive for his CPU cooler so he milled it out to accommodate.

 

If you're confident in your handiwork, it would be quite alright to do this. Doesn't look like there's a heat pipe inside this heat sink so you don't have to worry about rupturing anything.

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

Draws 400 watts under max load, for reference.

How many watts do I need? Seasonic Focus thread, PSU misconceptions, protections explainedgroup reg is bad

I think I may have solved it actually. It turns out that the heatsink is asymmetrical, so one side has more clearance than the other, so I rotated the heatsink 180 degrees so that the side with less is on instead. In addition, I screwed in the problematic side first, and it actually seems seated properly. If anyone finds this thread in the future, I hope this helps them as well...
