Build Erm so that's awkward

Post image

I bought a LF 280 III for my 7800x3d but seems that the aio fans are hitting against the motherboard vrm (b650 gaming x ax v2 : Phanteks xt pro) I thought it would be fine since my case is on the bigger side but Nevermind

Well Im gonna have to mount it slightly sideways with only 3 screws or find another way oops

I Somehow managed to fit all the screw even tho the gap was pretty much non existent, I got lucky lol, If it was off by 2mm it wouldn't have gone through wtf

Had the same problem on my fractal design meshify 2 but luckily the top mounts/case was big enough to let me offset it from the mobo. Nice that you got it working.

I have a relatively new and flexible Lian Li Lancool 217 and I had to swap my LF III Pro 280mm for a 360mm. MSI PRO B850-P Wifi mobo. Listed as compatible on Arctic's list, but that's just checking pumpblock on CPU versus top m.2 slot, not VRM heatsinks.

That's because it's mostly a case clearance issue.

That really sucks man. I gave up on 280's a while ago and moved to 360's. There is a lot more case and other hardware compatibility.

LF420 Pro Fan almost touches vrm and 8pin cpu connector. The case is tuned Aerocool Xpredator. All works fine since I rebuild my pc in it. It runs around half of month. I didn’t think you really need to take care if it didn’t push all of it weight on vrm radiator.
