Left is idle, right is under full gaming load (Helldivers 2). My previous rig (Intel) easily went up to 85-90°C in the same circumstances. Ambient temps are slightly elevated as well since we've been having ~30°C temps daily here for a while now.
To me this is almost ridiculous. I had never dreamed I could get my temps under load under 70. CPU is at stock speed since there is literally no reason to push it any further at this point. Can always choose to up the clocks later if I still want to.
Cooler is a Noctua NH-D15 G2. I don't see myself returning to watercooling any time soon. And Noctua has a new customer for life.
Haven't checked out many of their reviews I'll keep them in mind, at first I had them confused with guru3d who seem to come up often for parts reviews. I always like to find the worst points of a few reviews then if they don't seem too bad maybe the product is acceptable heh. Though you do need a handful to check for sure.
It's good practice to check multiple reviews. GamersNexus has very good reviews though, if I ever had to place my trust in just one review it would be theirs.
