Just bought this and now they say there is a PRO version 14.99?

That will give you fan control. THAT SHOULD BE INCLUDED IN A UPDATE. Instead I sent and got MAC FAN CONTROL - a FREE APP that will let you control your fans. I use this app (4.99) to view temps) I use the Mac fan control (free) to control the fans. I no longer have a fps drop as my CPU was getting hotter. I just programmed the free app to increase fan speeds as CPU temp went up.
5 stars - if not for trying to sell me a PRO version for 11.00 more! shame on you.
