Overclock of Pentium D 920

[SonofKrypton]

I just got a 920 for the price because I wanted to upgrade later to the conroe. With my custom watercooled system I got it to 3.6GHz at the 4-4-4-8 DDR667 and the temp of my cpu is 10°C and 12°C under load (7°C at standard operating speed). Has anyone else gotten these kind of temperatures with just water cooling.
I know that a closed system under vacuum can make the temperature of the water lower than that of room temperature and that the 5% Zerex coolant helps lower the freezing point (room temp is about 20°C ~66-67°F), but can it lower it by almost 13°C or is my temp probe not reading right on the CPU from the motherboard

I have seen many near this with air cooling...with water cooling that is actually kinda low....The problem with Prslers unless you spend near 200 dollars and get the Asus mobo you will have a hard time getting much past where you were...It is a mobo issue and not the chip....

I was getting strangely low temps with that with my 920 when it was running at stock speeds, on more than one motherboard(anywhere for 15c-20c). My second 920 is running @3.43ghz on a P5P800 SE and it getting around 35c full load on water cooling. 3.6ghz is nothing for a Presler even on air, but like Duvie said, the only people that I've seen hitting high overclocks are either on the Asus P5WD2 premium(955x), or P5WD2-E premium(975x). My 805 is running at 3.7ghz, but still hitting over 55c load on water.

Temps are reading wrong. Unless you got a miracle chip that gets colder, that vacuum theary would only be for a short amount of time, eventually the water would heat up to normal temps.

def bad temp readings, wish the intels really ran that cool
