Q9450 Thermal Sensors?

Alright, so i just got a new Q9450, seems like a pretty good one, i had a VID of about 1.15, at least that's what CPU-Z told me.

Unfortunately, i think my thermal sensor are either whacked or i did something wrong when installing the heatsink.

Speedfan reports my temperatures at idle (after calibration) to be 39 39 37 36. This is while speedstep is in effect, while i have 2.66ghz, 2.8ghz, or 3.2ghz.

At stock speeds my load was ~51 C

Right now i'm priming at 3.2ghz, with 1.20 V in bios, (1.184 according to CPU-Z) and i have an average of 59 C. Is this ok? Do you think i've done something wrong when installing the heatsink?

I have a Xigmatek S1283 (with the bracket) and a P5Q-E motherboard (latest bios). Oh, and i also have an Antec 1200 case with all the fans on full blast, so i would think that would help a bit...

And to get the VIDmax you need to disable EIST.

Your temps are a little warm, but not a problem. There are other things that can affect temps e.g., ambient temp, case air flow etc. I would test temps with Real Temp and compare them with other temps found on Google. Be sure to take account of the additional variables when comparing with other temps.

My Q9450 runs in upper 30's to low 40's idle on Water, about 50c Prime 95'd up, while at 3.4.

Not a lot of temp difference from 2.66 till 3.5, then got hot!

Quite a difference from my e6750 @3.8, running 40c at Prime.

Still about 8c lower than the Q6700 I had in before.

My vid is at 1.267ish at load.

Hmm, i think i may have done something wrong, becuase i've got my Q9450 at 3.4ghz with 1.25V (LLC not enabled) and while running Prime 95, im getting an average of 69 C

It shouldn't be this high should it? Espically with a Xigmatek S1283.

Edit: Do temps go down as you progress in Prime 95? Because when i began it was an average of 69 C, but now the average is about 63 C

I have my X3350 at 3.6 on air with the Zalman 9500 and prime at around 60-62 RealTemp. Your temps are good. It also depends on the room temp. If your room is 85F then you CPU will be higher. I would keep your temps below 65C under load.

RealTemp is the way to go. You can test sensor movement.


Edit: Check you heatsink pins make sure that are in, If you don't have the screws and bracket(get it if you don't).

Yes i am using Realtemp, and yes i am using the bracket.
Also, im doing Prime 95 Small FFTs
Lastly, i also retested, it seems that only during the 8k length part of small ffts do my temps rise above 65 C, the rest they are under 65.

Edit: My room is about 72 F or 22 C about

i wouldn't worry about it as long as TM1 & TM2 are enabled. if then you see performance degradation during your applications then it's time to bump down the voltage and over clock

First post after lurking without registering...

Anyhow, I got my new system put together the other day, only part that is used is my 3870 from my last system.

I have a Q9450 and I have a gigabyte galaxy II water cooling system running. I just got my system stable last night because it had a bad display driver and i had used coretemp and it showed that each core was around 50c.... i thought this weird because minutes before I'd been in bios and my pc health section had my cpu @ 15-20c

Last night I got realtemp and it showed the cores at around 37-40c avg which i still think is hot for stock settings...

i really don't want to rma the cpu if this is just a known issue w\ the sensors.

i guess thats a bad point about moving to the 45nm.

I thought they were supposed to run cooler, especially moving from an amd 6400+ @ 125w.... when i first got it w\ stock heat sink it was running at 75c and i found that out because i felt alot of heat coming up where my mouse was on my keyboard tray...

zalman 9500 got that down to 40 or so but now its almost 50 all the time.
