Irregular Overheating Problem

I have a P4E 3.2 overclocked to 3.6. My mother board is an Asus P4C800-E Deluxe and 1024 Corsair XMS TwinX. My system is liquid cooled using a Koolance case and Antec power supply.

I can run my computer indefinetly with a temperature range of 105 - 115 F. The problem comes when I reboot/shutdown my system. Upon boot up my processor's temperature sky rockets. I know that the temperature being posted is true, because I have external probes monitoring my CPU temperature that roughly collaborate my mother boards monitoring. I have resolved that it is not my cooling or cooling interfaces, but I am unsure if the cause is coming from the motherboard or the processor itself. At this moment I have clocked my CPU back to manafacturing specifications. I have also noticed that only warm reboots give me problems. I'd like advice on what is the likely problem so I do not waste money solving it.
 
I've seen some BIOS screens run the CPU really hot (I don't know if it's just poorly programmed and makes the CPU use 100% or what), and how hot does it get, and does it turn off from overheating, or what is the actual problem?
 
The over heating problem seems to be unrelated to processor load. Upon power up and even before I have entered the bios or started booting the OS the motherboard starts posting alarms regarding the processors temperature. However I have a short period of time where I'm able to watch voltage being delivered to the mother board. The power being supplied looks within normal operation requirements for 12V, 5V, and Vcore, which makes me believe that it is not related to voltage regulator on the mother board, but I'm unsure.
 
Are you sure it is not your cooling? Some cooling systems (fan and liquid cooled) stop during boots/reboots. In most cases, this halt is only for a few seconds, but a few seconds is enough to make temps skyrocket. Of course, they will come back down, but it can still be alarming. Check into this. i know my fans slow down for a few moments during reboots, so you could be having a similar thing going on with your cooling!
