Is it an or thermostat?

Are you getting coolant in your oil or vise versa

 

Nope, changed the oil.. thick

 

Make sure it's fully burped. Can be a pain to get all the air out on these cars.

 

This, 100%.

But also, I'm not quite sure I understand your problem. If the car is idling for an extended period of time, the fans should kick on. That's normal.

From my experience, with a 180deg thermostat (standard), a peak idle temperature of 205deg is also quite normal.

Regarding the intake temperature... this is generally uncorrelated to ECT.

 

Hopefully the radiator explode wasnt caused by a head gasket problem

 

Seems unlikely the rad would give without other symptoms so you're probably safe there

 

205f is normal it will get up there. Also check for bubbles on the plastic clear coolant overflow reservoir and if you see bubbles while it's idling then it could be that the head gasket has been breached. Sometimes you have to get into boost and then check for bubbles while it's idling.

 

I don't think it's HG, I've always checked the reservoir after driving long periods of time or after a WOT while letting the car cool off... I don't do any of that. Before I could hit peak boost at 17+ now it barely wants to reach 16 which is also wierd to me now.

 

Pressure requirements for rad cap? If your cap is not the right pressure coolant won't flow properly. Atleast that's what I found out with my 2011 wrx. The turbo coolant reservoir is a different psi than your rad cap. I don't know if this helps. Also could have air in the system which will need to be "burped"
