When I open Chrome Canary (the latest version) it opens on one of my extensions called 'Papier'
It's a note taking extension that I like.
I don't open any other tab and after like a minute, the iMac starts to blow like it's busy doing…
Doing what!?
I deleted all extensions that I didn't need any more, to a stric minimum, but still.
Anyone having an idea on what it could be?
I closed the 'Papier' tab and now I have StackExchange open, still blows like crazy.
I see 'SystemUIServer' in the processes that ask 180% ?!
I only have this behaviour with Canary.

Best Answer
I resolved this issue by doing the following:
I checked my Wi-Fi and Ethernet connexions to spot if there was a problem there and I noticed that there where more than 5.000 mach thingys active and the number kept on growing on the Ethernet connexion.
I first thought that it was some kind of DDos attack...
To be sure, I reset my switch.
Once the switch was back up, the problem was resolved.
Now the 'SystemUIserver' is running at 0.1% and this with like 10 tabs open in Canary.
