i5 661 , DH57DD , Over heating voltage regulator temperature

120mm front fan 1200rpm
120mm front fan 1200rpm
rear fan 2200rpm
cross-flow rear fan 3000rpm
totally aluminum case
no video card
one hard-drive
very efficient 500w power-supply
good air flow no obstructions
fans are set to full blast
All my settings are stock default.
I am not over clocking.
I’m not gaming just word processing and other light load work.

All other temperature sensors are far below the threshold and in the green.
All my power voltage indicators are in the green and stable.

Upper = 60C or 140F
Is the upper threshold of the voltage regulator temperature set to low?
I haven't found any documentation on the temperature threshold for the voltage regulator of the 661 or DH57DD.

I'm going to try a video card to see if taking the load off the 45nm on board video will help. If it does the maybe there is something wrong with the 45nm video chip. If anyone has tried this let me know.

If anyone knows how to spot where the temp senor is that would be helpful so i can see if it is a hot spot.

What is causing the heat?
iron choke
Transistors (MOSFET)
Capacitors

There are no heat sinks worst case scenario I can put a mod heat sink on the Transistors.
I will never purchase a board without heat sinks on the voltage regulators again.

My conversation with Intel Tech support.

->Daniel: Hello. Thank you for using the Intel Customer Support chat service. We are glad to be of service. How can I help you today?
you: Can someone post the correct upper threshold for the voltage regulator on the DH57DD. Many people are having difficulties with this we would like to know what to set it to manually. The current upper threshold is 60C. Please see the posts below for more information. http://communities.intel.com/message/95040#95040 http://communities.intel.com/message/92432#92432
you: Either 60 is to low or the sensor is off. People are getting warnings regularly.
->Daniel: checking...
->Daniel: Change the Intel® Desktop Utilities threshold to 90
you: Ok can someone official post that on both the forums i listed? So everyone has the information.
->Daniel: I will post on the forum, I will proceed with further research
you: Thanks for your help

Intel tech support told me the voltage regulator should be set to 90C it is currently set to 60C.

Intel® Desktop Utilities > Options > Set Sensor Threshold > Voltage Regulator Temperature > Upper > 90C
From : 60C 'or' 140F
To : 90C 'or' 194F

That sounds a bit on the high side to me. It sounds like you are just disabling the sensor warnings all together.

Can anyone post a picture of where this sensor is actually located on the board?
If anyone knows how to spot where the temp senor is that would be helpful so I can see if it is a hot spot.
What is a normal temperature reading for this type of voltage regulator?

I upgraded to the newest version of Intel Desktop Utilities. V3.1.1.012 i saw no change in the temperatures. I looked at the release notes for all of the Bios upgrades there is no mention of temperature sensors, thresholds, or voltage regulators.
