Looking for 12v 80mm fan recommendations - WITH remote temp sensor if possible

Ziggidy · January 8

Good morning LTT users,

I am looking to see if anyone can recommend an 80mm 12v 3 pin fan. It is for an application which cools a custom engineered (not by me) setup of 16 TO-3 transistors which are used to convert a PWM signal into straight DC. The transistors are mounted to 2 pieces of non-ferrous C-channel that I think is aluminum that is then held together with brackets to make a square tube. The 80mm fan mounts to one end of that tube to cool the transistors when they are in use. The current fan mounts to 1 end of the 'tunnel' to keep the components cool. The current fan has a 2 wire temp probe which connects to a 2 pin socket on the fan to vary speed.

Are there any quality fans that would fit the bill for a replacement? The existing unit is approaching 15 years old, and I don't plan to redeploy it when the unit is rebuilt for deployment.
