Ok, this thing is driving me crazy...
First off, the system :
- Asus P5B (without -E, -Deluxe, -whatever)
- Core 2 Duo E6600 at stock
- Zalman CNPS9700 led
- Corsair Twin2X 1024-6400C4
- Enermax Liberty 400W
- Asus 7600GS-Silent (passively cooled) (****ty, but I'm waiting for my 8800GTS to arrive)
- X-Fi Extreme Music (in second PCI slot)
- Maxtor 300GB SATA II
- Lian Li 767 case, Adda 12cm intake fan, Enermax 12cm rear fan (both to be soon replaced with two Noctua 12cm, I'm after a silent system)
Ok, here's the problem, at stock speeds, the system idles at about 40 °C, and so does the E6600 (Tc, as per Speedfan and Probe II). TAT reports about 30-31 °C for the first core, and 27-28 °C for the second one.
The CNPS9700 fan is at about 1900 rpms.
Now, I think the temps are somewhat high, and what is really puzzling me is the about 10 °C difference between the cores and the Tc.
Under load (Orthos + TAT, 100% on both cores), the Tc goes up to 56-57 °C, and the cores (as per TAT) up to about 42 °C.
Here's a graphic of the run (data from TAT) :
56 °C on Tc isn't what I'd call a good temperature for stock, even if AS5 is still not cured (I just reapplied it, this time with the credit card method
), and even 42 °C on the core is quite high, but what's really strange is that huge difference between the cores and Tc...
Any idea ? Suggestions ? I would like to overclock it to at least 3.2 GHz, but given these temperatures I don't think confident, at all...
