An oil is a loosely packed set of particles,which is why they are able to move easily and give you fluid consistency, hence will be lesser in temperature compared to the solid mass of metal.....How much of oil did you touch or pour onto your hand or fingers to know the heat ? I am sure you would have taken a few drops on the dipstick ,touched it and made your observation. First of all heat contained by the small amount of oil will dissipate into the colder surrounding and so when you touched it, it was relatively less hot. If you had drained the entire 1+ liter of oil and pushed your hand into it, you will know the actual heat,by touch(DON'T EVER DO IT).....
2. In the exhaust there is a Cat convertor which works on heat, and then you have the "silencer" and/or baffles which sends the hot gasses through a labyrinth to cool it so it's velocity diminishes and reduce the sound it emits.
The heat in exhaust,and engine will rise if you change to lesser viscosity oil (lesser particles),so engine oil does take heat away..many here have experienced it when they changed to a 20w40 from 10w30 grade oil.
Hope I make sense.

Yes it was just a few drops..
Well I just made a few experiments and some observations and based on your explanation, I could conclude that the oil does its job perfectly on transferring heat and lubricating. Am I correct Sir??
But still I don't feel any decrese of the amount of heat neither from switching from 10W30 HH oil to 20W40 mineral NOR from 20W40 mineral to 10W40 Fully Synthetic(very expensive too).. So still im in a confusion whether to continue use this oil.. Shoul I cover more Kms to make the decision? Already done over 600kms with this oil..
Ant thank you very much for the detailed explanation..
.I seriously fear for the jet force could bend the fins. 
on this things.
