I've never ever used a splitter on any of my Commander Pro, ever. Only used splitters on my extension fan card. What I'm saying is, the product should have the strength to handle the juice, because the Commander Pro is more oriented for advanced users, who generally uses big fans. Now that I know that I can either ask for a refund or a replacement, I'm choosing the second solution and I will split the load between the Commander Pro & my extension card. I just hope their V2 of the Commander Pro (if one is planned) will be more solid.

Well the fun fact is: I used to run 6 Noctua Industrial (3 120 & 3 140) (3x2 with splitter) on a simple extension fan card (from Asus), I'm not even counting the other fans connected to the motherboard, and I've never had any issue with that card, at all. (used this setup for more than 2 years on my previous setup without any issue) And I'm still using it with my current configuration, since I have to return another Commander Pro. The Commander Pro is supposed to be a premium product compared to that extension card, you can expect to be capable to run 6 fans without toasting a port. My VRM fan draw 0.18A for information. And yeah, 2400 rpm used to exhaust the huge amount of heat produced by a i9 7900x OC at 4.6Ghz during a workload. (I'm considering to delid it but... warranty you know..) But yeah, on my next Commander I'm just gonna plug 1 NF-A14 on the Commander, because I need it to be tie with a probe, the other ones will be on the extension card.

NF-A14 Industrial 3000 PWM to be exact. I'm not letting the fans spinning at more than 2400 rpm (mainly to avoid too much noise and the cooling is less impacted) and all my fans are using a custom curve. Also I've tried to setup the correct fan type (4pin or 3pin) in the Commander Pro settings (I was using Auto on the old one) to see if it makes any difference, but nop. Every time I've lost a port my PC was idle (so no huge power draw), It's hard to tell what is causing the issue. Note : It happened after the update of the firmware (to the version 0.8.210) but I don't think it's related.

Welp.. I was not expecting to see so many people experiencing this issue with the Commander Pro. My first Commander died recently (full shutdown, toasted circuit smell...) and not even 24h after receiving the new one I've already a fan port dead.. (it took more than 1 month to lose my first fan port on the old one) Apparently the Commander Pro does not like the Noctua NF-F14 (or F12) at all, since it's always a port with this fan that die first, and now same story on my second Commander... For information I've never used a Splitter. On my first Commander Pro I was using 4 probes, 2 RGB (4led strip + 2 fans), 5 Fans (3 NF-14 and 2 Corsair HD140) On my second Commander Pro I have the same settings, except I've just added a small 3-pin fan (0.18A) used to cool the VRM of my watercooled GPU. I guess the sixth fan was too much. My computer was not even in load when it died. So I guess I'll have to open a new ticket and will not connect more than 3 fans on the new one I suppose... With such failure rate, the only solution seems to be a Commander Pro 2 with a better circuit board.
