E6300 a bit hot

[ChrisR]

Hello!

I have an E6300 (cooled by Arctic Freezer 7 Pro) paired up with an Asus P5B Deluxe and 1 GB DDR2 667 Geil Ultra 3-4-4-8 (1 DIMM).

BIOS is 0804 and I have the following settings:


CPU Frequency: 430
DRAM Frequency: 533
Pci Express Freq: 100
Pci Clock Sync Mode: 33.3
Memory Voltage: 2.15
CPU vCore: 1.325 (stock)
FSB Termination Voltage: 1.40
NB vCore: 1.50
SB vCore: Auto

Multiplier is set to 7
Q-Fan is set on "Optimal".
Memory is set to 5-5-5-12

The system is Orthos stable, but when I run TAT (full load on both cores), I find the temperature spectacular high:

What can I do to drop the temperature a bit, without sacrificing FSB?

What kind of case cooling do you have?

 

[ChrisR]

I have 2 fans mounted in the case, one near the power button, and one under the power supply. Not sure about the dimensions (about 8x8 or 9x9 cm).

Definitely sounds like bad airflow...

...what are your ambient temperatures?

Try dropping the Vcore.

Those temps do seem quite high. I had a similar problem, and no matter what I did I couldn't drop the temperature. Anyway I read up on Intel's site and undervolting. The E6300 should be able to run with a Vcore of between 0.8v - 1.35v (roughly that range).

My motherboard set a stock of 1.325v too, so I dropped it. Eventually I got it so low that it wasn't stable (not enough power for the chip). But I got mine down to around 1.15v running with a 400Mhz FSB.

The less volts going through the processor the cooler it'll run. That dropped my load temps by about 12C. Try dropping yours if you can and see if it makes a difference.

Also a fan over the Northbridge helps. It keeps it cooler and moves the air in and under the cpu's heatsink. I used the Vantec bracket and a 92mm fan. The side of the case restricted the fan from pulling air through properly though, so I drilled a few holes in the side of the case.
