I recently assembled a Core2Duo E6600 System with Asus P5B Delux Wifi MB.
Note that I did not changed any params in BIOS.
When I was copying Huge no of files from old HDD(2 Copy process) Asus Probe 2 displayed warning that CPU temp reached 60 deg C.
Is This is a problem?
I was reading several OC forums and come to know that there are several CPU temp sensors.
Is Asus probe reads Temp inside CPU or something else?
Is it possbile to change asus probe so that it reads tem from some other temp probe?
Currently the CoreTemp showing aproximately 58 deg C(under normal browsing work)
and TJunction 85 deg C
I am too worried.
Currently I hv set all the values to min in bios (FSB 266)
I hve reinstall CPU and thermal compound?
Sounds to me like you don't have the CPU cooler fully set. I know you said you just reinstalled it, but I would check again. Those push clips can take a lot of pressure, just be sure to watch how much you are bending the MB when pushing them in.
Well, you need to check some things in BIOS. First, go into Advanced/CPU Configuration and set PECI to DISABLED. Also, check your Jumper Free Configuration in the BIOS and set AI Tuning to Auto and DRAM Frequency to AUTO. Now go to the Power section and select Hardware Monitor (takes a few seconds to read the fan RPM). For now, set CPU Q-Fan Control and CHassis Q-Fan Control to DISABLED. When you reboot, your fans (all of them hooked to the MB) should blow as hard as they can. After you do some experimenting, you can set these back to Enabled. I use the PERFORMANCE profile and it is still quiet.
OK, now you are as cool as you can get. As long as you took the previous advise and double checked your heat sync install. Also check your chassis fans to make sure they are plugged into the motherboard not into the power supply.
Boot up and load Windows. Download Core Temp 0.94b and run it. This is the best indicator of real core temps I have found (I've tried them all). If you want to futz around, intall and run ASUS PC Probe II from the ASUS CD and compare its temps to Core Temp. The ASUS CPU temp is always cooler. At idle it is more off than at full load. If PECI is enabled in BIOS, the ASUS temps will be much less than the Core Temp (as much as 16C less at idle). That's why you see all those posts bragging about 30C CPU temps and I can't get mine below 40C. Anyway, let it idle and see what the temps are. Your fans should be going full blast because you disabled Q-Fan in the BIOS. This is as cold as you can get. Stock, with no OC, I idle at 41-43C.
Now, download Orthos Beta (Stress Prime). Set it to stress CPU and run it. This will put both cores at 100%. Watch the Core Temp data and see where it stabalizes. Mine stablaizes right at 56C with everything stock and the fans at full speed.
Now you can go back into the BIOS and set the fans wherever you want. As mentioned, I use the PEROFRMANCE setting even while I'm overclocked. At 3.2GHz, 400 FSB and stock voltages, I am stable and idle at 48C, 64C full load. That's good enough until the new Scythe Infinity cooler gets here.
As far as I could tell, that settings determines when and how high the fans speed up. It does not effect their idle speed.
I set them to silent and heated my CPU up beyond 60C and the fans never sped up. In performance mode, they start speeding up at 58C and are at full speed at 61C. Never tried optimal, but I would guess it is somewhere in between.
One very important note: Q Fan uses the BIOS reported CPU temp to run the fans. If you have PECI enabled, these will be WAY low compared to Core Temp or TAT (like 16C low). What does this mean? If you are counting on Q Fan to speed the fans up and keep the CPU cool, it will never happen with PECI enabled because the temps never get above 40C (which is completely wrong).
I like Q Fan when I'm running stock speeds. I use it for 1 fan if I am overclocked (my top intake fan, which doesn't contribute much). I have 10 fans total (1xCPU, 1xPSU, 1xGPU, 7 case fans). With all but one on high, I can still here the clock ticking on the wall. I bought some really quiet (and powerful) Scythe fans.
Thanks for the info. Then another question. Any idea why there is such a huge difference between the CPU temp my bios shows (50-51 C, PECI disabled) and the one CoreTemp shows (41-43 C idle)? I'm running a C2D E6400.
