PSU Shroud vs triple front fans
These are some GPU Load tests I did a few months ago as I was putting together a new triple fan setup in my Corsair 4000D case…I’ve changed my fan profiles since then, so take what you will from these results…
1 front fan actually provided the best temps for some reason - I didn’t have a room temperature meter on me then, so the ambient temp may have impacted things…
Anyway, hope it helps…
