May we begin discussing the new RTX 3080 and 3070 in the DAN A4?
Just eyeballing it here and beginning to consider: how best to achieve proper airflow with these new dual slot 'flow-through' cards?
(and yes, check the rear of the 3070 – while both of its fans are front-mounted, it too features a pass-through vent on the back side)
Speculative ideas follow:
1. Rotate the PSU around, using its fan and airflow to assist in exhausting the GPU's. This would require trimming back the included plastic film.
Obvious concern: these cards will already be driving significant power consumption. Would flowing part of that heat through the PSU wreck PSU thermals? How would one even measure this – is there a thermal sensor in PSUs one can easily monitor?
2. Physically lower the PSU in the case. With low-profile modular cables and some standoffs from the top bracket this might be possible. Then mount a small fan above the PSU to pull up and exhaust both PSU and GPU heat.
I wonder how much clearance this might open up for rearward GPU airflow. One could fashion some additional shrouding to direct the heat and keep it from leaking over to the motherboard side of the case – a home-made chimney of sorts to keep the PSU (and GPU) exhaust exiting through the top of the A4.
Obviously, either of these schemes assume air cooling for the CPU and a standard SFX (not SFX-L) power supply.
Thoughts?
