Just finished my first custom loop! I used Light Wings LX 140mm PWM high-speed fans for the top and rear, and Silent Wings Pro 4 fans for the front. The rear fan is configured for intake, and while I can tolerate the way it looks, I'd prefer to use a reverse fan here. Is there any potential for a reverse variant of the Light Wings LX 140mm fan to be released? I know there's already a reverse variant of the Light Wings 140mm fan, but I'd prefer to use an LX fan here.

I like the two-tone aesthetic, but there isn't enough silver imo. I'll probably either remove the silver fittings for all gold ones when maintenance time comes around, or I'll replace the gold fittings coming from the reservoir with silver ones; haven't decided yet. Probably should have rendered out my 3D mockup before I finalized the fittings.

Temperatures seem nominal; CPU idle temps in the mid 30s, although I haven't overclocked anything yet. Coolant temp. is around 33°C. Not sure if I need to calibrate the flow sensor (haven't read the manual) but the flow rate is around 210 l/h at 100% rpm. Not sure what the GPU temperature is under load, but I got the achievement in 3DMark for staying under 65°C during a DX12 stress test, so everything is probably alright.

I read some comments stating how the High Flow Next might potentially make noise if not given enough tube length on either side, because of turbulence. This doesn't seem to be the case in my instance despite my somewhat peculiar placement, so I'm not sure what to think in that regard.

Here's the loop order:

• Reservoir → Front Rad. → Top Rad. → CPU Block → GPU Block → Reservoir
