My fans really don't make much noise anymore but that's the fault of the overdone loop more than anything else.My days of overclocking and tuning stuff to within an inch of its life at tornado fan speeds for miniscule native res gaming gains are over. For me It's all about power saving, lower heat and as close to stock performance as possible.
My rig passes 30 minutes Cinebench, 1 hour Realbench, full coverage in HCI MemTestPro, done in an afternoon.
My real test is normal usage - hours in sensitive games like GTA V, Warzone, Cyberpunk, all the modern stuff with shader compilation which pushes 100% CPU usage for minutes, etc. No WHEA popping up, no BSODS, runs well. Temps all in acceptable range.
I'm sure there are way more comprehensive tests (and some still believe in the good ol Prime95 for 24 hours) but this worked for me with my previous setup which didn't give me any trouble with gaming and general use. If it crashes I will reevaluate.
Also, I still think opting for Corsair over Gskill was the right choice for my setup. Mainly because even with the improved cooling of the Corsair ram, and with a Corsair 60mm ram cooler at 60-70% fan speed too, I'm reaching 55C in gaming.
Obviously different for another person, if they can get low 50s on GSkill then all good. But for me it would be more difficult due to the big hot 4090 efficiently cooling its core (mid 60s) but venting all that hot air into the case. The CPU also vents hot air in through the front radiator because the top-mounted radiator option would involve all that hot 4090 air going through the radiator which makes cooling an already hot Raptor Lake even more difficult.
If you're happy with your stability then that's cool, but cinebench has never been a good enough stress test to ensure stability.
Having your GPU dumping loads of heat into your case really is a problem because you're running a fan and you're at above 50. My Gskill are all the way down at like 45 with no GPU heat And the air from the front rad doesn't really make it to the ram sticks with my setup.
Edit for clarification: your GPU isn't an issue but might want to look at doing something to cycle some heat out of the case or add more cool air because although not harmful 55C and 60% fan speed would be annoying.
And although I might be biased with my current loop but Raptor doesn't run all that hot. Yes sure Techtubers are having hot runs at stock because at stock there's just way too much voltage being pumped into CPUs vs what they actually need. And during gaming loads there's really not all that much heat.
