Yes- I always do?Have you connect antenna to this card?
Overheating may be caused by high SWR ... check if your antenna system is OK, that cables are OK, connectors are in good condition and soldered/crimped in a proper way and there is no obstruction close to the antenna that may cause high SWR ...Weird that they are so hot, maybe this is one of their properties and is this normal.
Attach a XR5 card to 433AH board onto a test antenna or dummy load (tried two other 433AH )and it runs nice and cool but put back R5SHPn and tried two others and they all run hot?Overheating may be caused by high SWR ... check if your antenna system is OK, that cables are OK, connectors are in good condition and soldered/crimped in a proper way and there is no obstruction close to the antenna that may cause high SWR ...Weird that they are so hot, maybe this is one of their properties and is this normal.

Extra cooling never hurts right I said.A fan mount is a good thingI started using R5SHPn cards, but it heats a lot. I just wanna ask, do You use fans in outdoor cases ? Does fan affect on cards and signals ? Whats Your opinion? Thank You
