Something else is wrong then as that is not possible on air or watercooling (unless you are using chilled water).

So every temperature monitoring program lied? I find that somewhat unlikely. The whole point of a smaller architecture is lower voltages, thus less heat. When you look at good air cooled 90nm CPUs, which ran at 1.4V stock or so, 40C load with a Lapped Big Typhoon at stock voltages was not unheard of. What makes it so hard for you to believe that a CPU running at lower voltages can get better results?

2C above ambient at IDLE is hard to believe on watercooling...if you are getting that on air under LOAD then it's obvious that they are highly inaccurate readings.

There is no way that an air cooler could dissipate heat that efficiently...even if it had a bajillion fins and thousands of fans, the heat from the CPU cannot transfer to the base of the heatsink quickly enough to get you temperatures like that.

I would say the most likely explanation is that you have faulty temperature sensors...something fairly common with wolfdales. I've had a few like that.

What are you using to measure the ambient air temperature? Because I have a feeling it's measuring heated air. If not, then it's definitely a busted temperature sensor.

Naw, 30 degrees is normal for inside a house, so yeah, it's just the CPU. I get 32 degrees at idle, upwards of 45 under load, under stock voltages with stock settings.

Listen to this person, it's practically impossible to get that close to ambient temperature, that's just not how traditional heatsinks are able to operate.

Thread Starter 
I just reseated the heatsink and cleaned the coolers and put new compounds. Now I was running the Super PI and in the round 10 it said "not exact in round". I just changed my RAM to the dual-channel for better performance and I increased the DRAM voltage up to 1.90V and NB voltage up to 1.20V, CPU voltage is 1.25V, so, more needed?

While running the Super PI:
MB temp: +40`C
CPU temp: 38-42`C

Okay what should be enough, because I don't know how much voltages needed.

CPU Voltage: should I set it at least up to 1.30V or higher?
NB Voltage: 1.20V, more needed?
DRAM Voltage: 1.90V, probably needed over 2.0V?
All other voltages: Auto
FSB: 450
Multiplier: 9

After losing RAM timings, it'll loses a lot of performance, because I've been using 5-5-5-12 and with 5-5-5-15, oh my god, no thanks! Next I'll be increasing the CPU voltage up to 1.30V and check out my temps.

I would try reseating your HSF, though. Getting high temps at 1.3V shouldn't be an issue. Even at 1.35V, my CPU runs 2 degrees over ambient at full load. So, I would definitely check to make sure that your HSF is seated properly if you start to run into any temperature problems in your OCing endeavor.

2c over ambient is impossible
Your sensors are wacked.
Get the latest version of RealTemp and calibrate your cpu:

http://www.techpowerup.com/realtemp/docs.php

When calibrated at these reduced clocks your cpu should be 3-4c over ambient. My ambient below was 24c



Then do a sensor test to see if any are stuck:

and someone was asking about my VID: 1.2000

With these settings in BIOS, I made it to the 4.00 GHz. Super PI successfully ran all tests and also Orthos. I'm very proud of my performance and the system. I would get easily higher with a 1.35V CPU voltage, but no needed and I'm not sure could my NH-U12P handle it, because currently under LOAD, temperatures are around 40`C.

Just because I'm sure you all cared...

I downloaded the newest Realtemp, and ran Small FFT Prime 95. My CPU is currently sitting at 3.78 GHz with CPU-Z detecting the CPU VID at 1.312V, and my load temperature is fluctuating from 47 to 48C. Sorry for my stubbornness, but I figured since my load temperature on my 65nm Brisbane was in this range, that it made sense for a 45nm to be cooler, at a lower voltage, but apparently not.

So yes, it was a sensor calibration thing. Sorry for the confusion.

no worries, glad you got it cleared up.
