[SOLVED] Asus ROG Helios Cooling

[Ahxakri]

Well, I have a bit of a possible issue. My CPU is idleing around 40c and I'm trying to get that down at least 5c.

I have replaced fans and was curious if it's a problem with my cooling setup or fan choices.

I have 4 CoolerMaster 140MF fans. 3 on the front of the case as intake and 1 on the back as exhaust. Also, as a side note, they're running at a maximum of 1500RPM when advertised as 1800. They're connected to a hub in the back of the case. All 4 are running from the CPU_Fan header. Should I take 1 off and put it on the CPU_OPT? And/or possible other inputs.

I have the Asus Ryujin 360MM mounted at the top with 3 Lian Li Bora-Digial 120 fans mounted on the bottom of it as intakes.

My CPU is an i9-9900K OC'd to 5.0Ghz on an Asus Maximus XI Hero (Wi-Fi). Ideling at 40c and about 50-60 when playing FFXIV and a couple of other titles. Let me know if anymore information is needed, thanks!

Nothing seems unusual to me. Your case basically needs all the fans just to be an average case thermally, and you have a hot chip that you're overclocking. 35 vs. 40 idle is meaningless and there's nothing remotely wrong with your temperatures at load.

Minor Variations in ambient can vary 5C so you have nothing to be concerned about.
CPU_OPT is a replication of CPU_FAN header. Use a splitter cable to use two fans on each.
You need 4pin pwm fans for control in Bios fan curve control ( some MB's have DC control) 3pin fans require a hub.
Fan connection from the radiator fans to CPU_FAN should be always left at 100%.
