Still unable to upgrade, as usual, and instead of only one bend, I have more bends, changed few fittings as some of them seemed to have worn out, also uses all ek fans this time. Not all of them uses the same fitting series because the local distributor ran out of stock when I needed them 😅

I don't know why, but when I installed the side radiator using the vardar fans, 2 of the bottom fans always hit the screw holes of the case when turned on. previously I was using the noiseblocker fans and had no problem, maybe because its fan blade design? So I decided to put some sort of spacer between the fan and the case and problem solved.
