This feels like a SilverStone endorsement being pushed by Tom's Hardware SilverStone cooler, case, and PSU really now? sorry that's "not" coincidental at all
Thanks, but I'll stick with my Seasonic X 400w fanless PSU it's received better praise then the SilverStone PSU in testing.
I'm also context with my choice of a Sunbeam CR-CCTF 120 mm Core-Contact Freezer w/o the fan that I picked base on it's temperature results on FrostyTech for at low fan rpm speeds because at the time I bought it at least it tested better in that regard then any other cooler on the site meaning it was exceptional passive cooler because it handled low case airflow better then the other coolers.
My case could be better, but the one I would recommend for a compact case as the best would be a COOLER MASTER HAF XB RC-902XB-KKN1 because it provides the best unobtrusive airflow for heat to escape through to provide optimal natural convection for case in that form factor in a slightly bigger form factor the Xion XON-570 case is a strong recommendation as well.
For a case you want one that can "breathe" well for hot air to escape since heat rises you don't want your case to be like a hot air balloon with heat trapped inside in a passive cooled PC it's that simple it's basic logic.
You can call me crazy if you like, but I've actually built a 0db passive PC that I've had for 2-3 years now and encountered no problems with it thus far in usage and don't have a quite obvious unethical ulterior motive Brand product placement like this Tom's Hardware article clearly does here which irritates me a bit as the site use to be more about benchmarking then product placements.
