I’m a bit irritated as I find different recommendations concerning the fan for the heatsink of the Ryzen AI Max+ mainboard. I plan to build my Desktop myself, so I only ordered the mainboard.
When reading the FAQs for the Desktop, it’s stated, that the fan should at least offer >100 m3/h airflow and >3mm H2O static pressure.
On the page for the mainboard, the recommendations are different: “For the 120mm fan, we recommend a minimum of 85.1 CFM air flow and 3.82 mmH2O air pressure.”
That’s quite a difference, and I’m wondering what recommendations to follow …
I aggree with JTrevail. You are probably overthinking it. If you are unsure which fan to get, just get one of the two officially recommended ones. They are easily available in most markets and are also among the most silent ones that still perform.
If you don’t want to spend the money for a Mobius 120 or a Noctua NF-A12, a reasonable budget alternative would be the Arctic P12.
100 m³/hour = 58.9 CFM on the framework desktop spec page, vs the 85.1 CFM spec on the mainboard spec page. Yeah, it’s a big difference, and a typo/information with missing context on Framework’s part. I’d pick the bigger number and move on.
Be aware that the Phanteks T30-120 is thicker than standard 120 mm fans. (30 mm, as its name suggests, instead of 25 mm). I don’t know if the Framework Desktop case supports that extra thick fan.
I would recommend staying with fans of the same physical dimensions as the two officially recommended fans which is 120x120x25 mm.
You are right of course. I just wanted to highlight this aspect because some may not have it on their radar that mainstream 120 mm fans can come in different heights.
Thanks for all the helpful replies. Yes, I’m aware, that the Phanteks T30 is thicker than the average 25mm. Right now, I’m waiting for the specs of the upcoming Noctua NF-A12-25 G2 – maybe that one is going to be a good solution …
