Asus P5Q Pro CPU/MB temp issue(with speedfan screenshot)

[geek101]

Motherboard temperature hovers around cpu temperature and reaches 40C for idle and 50C for 100%. CPU varies from 40C idle to 70C at 100% load (prime test).

Also at some point the CPU temp sensor reports 125C but all the cores are only at 60C.
This was really troubling, the CPU did not shutdown so somehow the MB sensor freaked out?

First of all the motherboard temperatures seem to be high considering CPU is at the same level for idle. Is this because of MB temp sensor placement and the GPU I have ?. Radeon HD 4850 runs hot usually around 60C to 80C.

I have not done any overclocking infact speedstep is enabled and having intel stock heatsink for now. My case is Lian Li PC-7B plus II. It has two 120mm fans for intake and exhaust.

This is my first build and I am planning to overclock the CPU using a lapped Arctic Cooling Freezer 7 Pro. Do you guys think I have to work on my MB temps first before heading on to overclocking?.

Any input is helpful.

I have a P5Q-E and am having temperature problems I think. First, Asus released a new bios that was supposed to fix cpu temp reporting. I have been running Prime95 for 25 minutes now and Asus probe, as well as speedfan is showing mb temp of 42, cpu temp of 30 but the cores are varying between 54 and 59 degrees. I assume that if the mb was reporting temps properly and the core temps are correct, the cpu temp should be reported around 46 - 48 degrees.

I am running a q6600 with a Zalman 9500 cooler. I OCd the cpu to 3ghz by raising the fsb to 333. Nothing else is overclocked. When I started to run Prime95, the core temps shot up to 67 so I went back to no overclocking.

I know the bios is screwing with the cpu temp for sure but could core temps be off as well? I am not comfortable with temps in the high 60s. I can try reseating the cooler but don't know what else to do.

The sensor is malfunctioning. I've seen the exact same issue. Anyways, I pretty much just disregard the "CPU" reading and go with the Core 0 / Core 1 readings that SpeedFan and CoreTemp show.

The sensor error seems to happen somewhat randomly. In my screenshot, you can see that I'm running Prime, but I have had the sensor shoot up to 124C while the rig was idling too.

I did find that rebooting sometimes put the cpu temp more in line with what it should be. I haven't seen the huge 120+ temps for cpu though. My concern is more the core temps in the high 60s. I don't want to fry the cpu.

My Setup is
Antec Designer 500 with 120fan to blow out and 2x92mm front Arctic Cool fans to blow in through HDD,
CPU is E7300 running at stock clock speeds of 266x10 @ 2.67Ghz

HDD WD 400GB ----- @ 36C
HIS 4870 ----- @ 71C Idle - 75C Load (normal),
Asus P5Q-Pro ----- @ 45C Idle - 52C Load (is worry),
CPU with Stock Fan ---- @ 30C Idle,
CPU Core0 ----- @ 52C Idle - 60C Load (is worry),
CPU Core1 ----- @ 52C Idle - 60C Load (is worry),

Do you guys think that I should be worying about MB and CPU???
Any help is appreciated.
