Hello,
is it normal for a Fancon to generate so many IRQ? ~1400 per “tick”.
CCR1009, v6.47
Same issue here:

We also notice performance issues. Some VPN clients gets the downlink 10x slower than usually and cannot establish remote desktop connections to internal network hosts. Some other has no such issues. I accidentally noticed this suspicious Fancon IRQ counts. Could it be related?
Is like all at default… ??? 
Is like all at nondeafault…

Yes, this is normal behavior. Depending on the model it can be 1 to 4 IRQ per one fan rotation.
