Asus P5K Premium - Low CPU Temp

[RichardU]

I have a brand new Asus P5K Premium running Vista 32. Specs below.

I'm getting an unusually low reading for CPU temperature - ranging from 11 to 13 degrees C. which is colder than the room. My motherboard temp is 35 degrees C.

I get the same readings in the BIOS, with Everest and with PC Probe II, although occasionally PC Probe II alerts and says my Motherboard is 153 degrees C. when clearly it is not.

Has anyone else dealt with this? Should I RMA the board? Seems to work fine otherwise.

Asus P5K Premium / Revision 0102
Intel E6750, Ultra-X Cooler
Crucial Ballistix PC2 8500, 2 gig
EVGA 8800 GTS 640
Antec P190

Over 30 people looked at this and no responses. I guess it's not a common problem.

I called Asus Tech Support and they told me to upgrade the BIOS. I did and now the CPU temp reads about 17 degrees C. which is still colder than the room.

RMA to Newegg.

no no.

there's nothing wrong with the board.

it has to do with the new G0 chips.

for some reason temp software/programs seem to be reading the diode temp or core temp about 10-15C's lower than what it really is.

there are plenty of threads about this in the cpu/overclocking section

Asus tech support told me to RMA the board. I'm glad to know it wouldn't make any difference, except a lot of hassle for me.

Thanks,

ah stupid tech support lol

sounds just like Giga and abit... ALL their boards read this low.
NOW Asus is starting to follow suit.
The low readings on the other boards are blamed on cheap chips and/or bad placement etc.
So Asus is using real cheap stuff too. beats me ( probably ) but I would not worry about it.

does core temp and/or speed fan work any better?

35 degrees Celsius = 95 degrees Fahrenheit so I don't know where that big numbers are coming from.


I would not send it back...that is a pain with asus. I sent one back a few years back...OVERNIGHT charges both ways (work and need it now) they sent it back AND NEVER OPENED THE DAMN BOX

needless to say it didn't work and we had to do it all over again...nice to have a nice tech sheet that showed all the test and work they did on it...I GUESS they have things that do all this thru the box.....DID I MENTION it was NEVER opened?????

I have a similar problem with my Asus P5K Deluxe &E6750.
I suppose I shouldn't use Q fan then as it will not throttle the fan correctly?

Anyway thanks for the posts, it was beginning to bug me cause I plan to overclock at some point.

Cheers.

I have the same problem with my P5K Deluxe Wifi MB (Latest released non Beta BIOS 0404) and an E6850. I have a room temp of ~28C and the CPU shows only ~18C but the MB itself shows ~48C.

What will happen in a overheating scenario, will the CPU shut down ~15 degrees too late!!!

Is there any solution to this problem?

Nothing wrong (re: the temp readings) that won't hopefully be fixed in the next BIOS rev. Two things you can do in the meantime.

1) Turn off PECI in the BIOS. This should cause the reported CPU temp to go up about 15 degrees to a more believable temperature.

2) Use Speedfan to control the fans and use the Speedfan advanced config tab to bias the 2 core temps up by 15 degrees. (www.almico.com)

All this was evidently caused by changes that Intel has made in the G0 chips - the MB manufacturers haven't caught up yet

Thanks for the reply! I read aboput the Tjunction has changed from 85 to 100 for the newer CPU.

1. But is that value derived from the BIOS, that is, it's nothing I can change myself?
2. Can speedfan override the setting from the ASUS Q-fan?

[RoyB]

As far as I know the value cannot be overridden - it's set when the BIOS detects the CPU type.
also AFAIK - Qfan and Speedfan are mutually exclusive (for controlling fans) except that in Speedfan you have the choice as to whether it controls the fans or just displays temps, speeds and voltages.

Thanks for the reply. I will try to elaborate with Speedfan and use it's temp offset.
