Oh so you have your 90mm exhausting out of the case underneath the gpu? Would have thought it would be better to intake and blow directly over the nvme and board. I've got both of mine as intakes to bring some cool air in which helps cool the top rad and also the VRM. I've mounted a small 40x20mm noctua fan that runs around 4400rpm (surprisingly quiet) which keeps my vrm's cool as im running a clocked 9900k. Keeps those vrm temps below 60c.
Haha its not that bad, once you get use to it its actually fairly easy. Just test mount everything before diving in, make sure all the areas that need covering are covered and contact is made properly over the die, memory etc.
The little decals were a final touch, think it needed it but not sure whether to keep the ones over the FLT's just yet. Kinda wish they were transparent...
I'm still fine tuning the RGB, think theres abit too much light still. Need to dim it down a little in some areas.
