I want to build a PC with Ryzen 7 1700 and build in the boxed cooler Wraith Spire. it is a 160mm kind of CPU fancooler (I'm sure it is) and the case that I want is 200mm wide. Now my question is, if the air that is blowing out of the cooler horizontaly and there is a ca. 40mm wide space for the air to be pushed to the side, is it enough space? or will it cause problem with the cooling or damage the window like my case ?
Thank you for help!
The Fan works the other way around., it doesn't push air out it draws it in.
Ideally you want > 3" (76mm) Clearance … but no less than 1" (25mm).
This said you know the Wraith Spire is only ~80mm Height (110x110x80mm), like half the height you think it is.
The Wraith Prism is taller at 95mm and Wraith Ripper is 140mm (although as a note the Ripper is a Vertical Airflow as opposed to Horizontal).
200mm Clearance should frankly be fine for any fan.
