All fans are blowers. You want a radial fan; your example was an axial fan. Good terminology helps.
I’ve personally only ever seen axial fans like that.
Thank you for the responses, apologies for any confusion, I was only going by the terminology that I have been exposed to from my current suppliers and manufacturers.
Essentially I need to cool RAID controllers, at least 2 in the same system, in 45 degree Celcius ambient heat. I have had to change case due to other requirements so I am reviewing how to cool these components effectively.
I was thinking along the lines of this, but with a thermistor:
In case you are open to DIY, search for “Digital Temperature Controller”. Those would then allow you to use any fan you see fit.
Or, if you are open for more DIY (or space constraint), using an ATtiny85 with a K-Type is pretty straight forward, just add a voltage regulator, some passive components and a MOSFET.
