Hey guys  
Do you know if there is enough room for this fan to sit on top of this Poe hat?

# Smart Cooling Hat For Raspberry Pi 4

SKU: DFR0672 Brand: [DFRobot]

With this

# Power over Ethernet HAT (E) for Raspberry Pi 3B+/4B, 802.3af-compliant

SKU: WS-23285 Brand: [Waveshare]

Thx!

Hi @Robert164578

Looking at both of those hats from your post I would say there is better options for having PoE and also active cooling, being either the [Raspberry Pi PoE+ HAT](https://core-electronics.com.au/raspberry-pi-poe-hat-48803.html) or [Waveshare Power over Ethernet HAT (D) (Pi 3B+/4B)](https://core-electronics.com.au/waveshare-power-over-ethernet-hat-d-pi-3b-4b.html).

Thx Dan…  
I forgot to mention…the only reason I chose that hat,is RGB

Otherwise I do have other cooling options, but extra rgb is always nice 🙂

Let me know when you can if it’ll work

I have a few old those PoE hats, and the gpio pins from the pi do not protrude out from the PoE area which covers the first top 6 pins, (1-6 5v, 3v gnd etc), so how would this hat receive power? Is a crazy work around even possible?  
😁

Hi Robert,

Being that the headers don’t protrude from the PoE hat you would need to look at using something like [PoE+ HAT Push-Fit Extra Tall Header Kit](https://core-electronics.com.au/poe-hat-push-fit-extra-tall-header-kit.html) give you some extra pin length through the PoE hat.

That’s some big pins.  
I think that’ll do the trick!

Thx!
