AIO of my itx build died, so needed a new cooler. Considering the limited lifespan of AIO and the amount of waste afterwards, it seems like the low profile fan coolers is the better option.
I was originally going for the Alpenfohn Black Ridge but it's OOS at PCCG (while too expensive elsewhere).
Noctua prices especially in Australia are baffling.
Ships from Taiwan. Claims to deliver in 5-17 days for most of their customers.
(EDIT: My order just shipped, and it's being couriered by DHL.)
Same reason i bought the Alpenfohn Black Ridge. My AIO died in a little over a year and I decided to move to the air cooler for my ITX build.
Both this Noctua and the Alpenfohn are great ITX coolers.
I still use CTR to undervolt the Ryzen CPU to reduce heat load as these coolers will still struggle with a high power draw cpu.
