Скачать или смотреть Noctua Was Right: Top Exhaust Fans Can *HARM* Thermals

** If you enjoyed this video, please consider checking out my smaller second channel too:    / @shortertechoverwrite  

Since hot air rises, it's always been recommended to set your top case fans to EXHAUST - y'know, to remove all the warm air from your CPU and GPU. But I recently tested this, and this case fan configuration can actually harm your computer's thermals.

Which sounds counter-intuitive, but as I show off in this video, it actually sort of makes sense when you see the airflow analysis results (I used smoke matches - which are really fun to mess around with, by the way!).

I also done some stress tests with Prime95 and Furmark to record the exact thermal differences for four different fan configurations:

Fan Config #1 - both top fans are set to exhaust
Fan Config #2 - one top fan is intake, the other is exhaust
Fan Config #3 - both top fans are set to intake (not a good idea)
Fan Config #4 - zero top fans (I taped up the top fan grill)

For reference, you can find Noctua's airflow guide here - https://faqs.noctua.at/en/support/sol...
