If that's a case fan then yes all cases fans can be replaced just make sure it's the right size don't buy a fan that's way too big or way too small

All fans can be replaced in every PC, you should have checked the DELL site for information regarding your PC.

You will have to remove and examine the FAN to know what to buy as a replacement, they did not all come with just a single size because the Brackets outer size are the same for other series. You could have a 70mm, 90mm or even a 120mm Fan depending on when your PC was made and what was in stock from one of the three suppliers that made the Fan assemblies.

It seems to be a proprietary fan, because it is part of proprietary CPU heatsink.

To OP: why do you need to change it to a smaller one?

It has two fans one on the CPU and one case fan. He never stated the CPU fan nor did I list it because of that but both can be replaced with aftermarket units. Going with a smaller fan on either one might be problematic if your Mount is expecting a certain size. These units are not like a typical ATX design that allows you to use different sizes.

2 fans? Where

Only 1 fan sits between CPU and front panel and acting as intake fan, taking air from the front and pushing through CPU heatsink inside the case, there nothing on the back panel - it is BTX design!?

You would be correct, 1 fan on the CPU 1 in the Power Supply with a Thermal sensor to control the Speed, yes it is a BTX. There use to be a issue with Temps from faulty Thermal sensors so we would install a 90mm low speed fan directly on the back of the Case which would solve that issue if the Sensor failed. I guess I got the 960 and 760 confused on the 2nd post.

I am not arguing here, but you just stated that

It is not factory installed, it is aftermarket solution to improve cooling and OP is asked about changing main, CPU fan I guess.... This small 80mm can be added to any BTX Dell, no matter the model.
