Whats too hot for an Asus p5k deluxe?

From the ASUS faq the operating temperature range of the motherboard is between 0 to 65 degrees Celsius.

The reason for the high temperature reading is due to the motherboard temperature sensor being near the Memory VRM area, which has no fans blowing in that area.

I forget the exact location of the sensor, but I think it is above the RAM slot area.

Edit: Found the FAQ
ASUS Motherboard FAQ
 
My P5K deluxe sensor reads around 38C in an Antec Sonata 1.0 which
doesn't have the best airflow so it runs on the hot side.

I'd look at changing your cables and maybe increasing the case airflow by speeding
up an intake or exhaust fan, adding another fan for better airflow,
using a PCI-slot-cooler fan or whatever to get more hot air out of the case.

I don't think 48C is a horrible motherboard temperature at maximum PC
load in a warm room, but I think it is on the high side and can probably
be improved through better airflow if you have a case that's roomy enough
to get things a little more openly ventillated.

If your CPU's staying cool under max load and the system is stable I guess
it's all "OK" but "could be better".

 
Heh, i leave my side door open all the time and such. idunno, iguess im not worrie dabout it seeing as my e6850 is overclocked to 3.8 and runs ad 10c idle and 20c playing Crysis 🙂
 
Don't worry too much about the motherboard temperature. At first I was quite alarmed at the high motherboard temperatures as well (mine idles at 48C in a hot summer room).

That sensor temperature depends too on the type of heatsink/fan you have on the CPU. With a stock Intel heatsink the sensor reads much lower because the stock HSF is "omni-directional" (down blowing) thus there is some airflow to the parts around the CPU socket. Of course, if you have a side-blowing "upright" HSF combo (like an Thermalright Ultra-120) there will be little airflow to the parts around CPU socket since the airflow is not directed in any way towards the motherboard.
 
It's not to hot but unless you have good airflow w/ a down faceing fan on your HSF for the cpu you may have issues w/ this. I'd say about 55C is safe in asus probe if it goes higher then you may want to worry or add something like an Antec spot cool.
