#pcbuild #RTX5080 #asuspcdiy - It's big, it's bold and certainly cools. It's time to enter the HAVN HS 420 VGPU for some epic airflow action!

Timecodes, though I don't recommend skipping for visual narrative reasons!

The HAVN HS 420's have been requested on the channel ever since their launch, and whilst it's taken a little time to get there, I'm stoked to finally share with you my latest RTX 5080 build with the VGPU version.

It goes without saying that there are few cases on the market which can truly rival the cooling potential with this one. I built with eight 140mm Phanteks fans (four in, four out) which gave this system more airflow than it could ever need. It's crazy to think that there was still space for a further three 140mm fans if needed on the side panel too!

HAVN have truly embraced something a little different here. The bottom intake fans came into their own with directing the flow of air towards the GPU which was evident during testing. We didn't anticipate the ROG Astral to exhaust through the cable management holes however, but that was really awesome to see!

As a new challenger to the table, HAVN have made an incredible entrance to the PC DIY space. With 50 series GPU's now slowly entering the market, this one will certainly hit the spot for keeping low temps with huge hardware visibility thanks to that massive curved glass panel. Very excited to see what HAVN come up with next!
