Q9450 Heat

[ViperThreat]

Hey guys, Just yesterday i noticed that my processor was hitting some pretty high temps, so I took a deeper look. Using a couple different programs at ilde, i got these numbers:

Real Temp
Core1: 56 Sensor Movement: 11
Core2: 55 Sensor Movement: 10
Core3: 56 Sensor Movement: 10
Core4: 56 Sensor Movement: 09

Core Temp
Core1: 61
Core2: 61
Core3: 61
Core4: 60

Speed Fan
CPU : 47
Core1: 62
Core2: 62
Core3: 62
Core4: 60

So I shut down my system, unplugged all my goodies, and pulled the processor/heatsinc out. I thouroughly cleaned the processor and heatsinc with alcohol, and rebuilt. Numbers havnt changed. Im goin nuts here!
System is

Q9450
Zalman S7000C CPU Heatsinc
Nvidia 780i
2g Corsair DDR2
500w Ultra PSU
X1900XT
2x 500g HDs

Any Ideas?

need more info. are you running the chip at stock clocks/voltages? what is the ambient temperature? mounting mechanism for the CPU? thermal compound used? what case are you using and how is the air circulation? method of applying thermal interface material? these things are important.

btw welcome to AT . you might be able to find more information if you read some of the overclocking guides here as well. stop by the cases and cooling section while you are at it. if you are overclocking your CPU your cooler is probably inadequate. zalman coolers tend to be best for quiet rigs.

 

[ViperThreat]

In the order you asked.

-Stock Clock Settings (no need to OC)
-Ambient room temperature varys between 65-75 farenheit
-Not sure what mounting mechanism means its a 780i mobo, nothing modified
-Arctic Silver
-NXZT Alpha Case, Aiflow is decent, far better then other cases ive had. currently the side of the case is open for excess airflow.
- Applying a thin line across the processor as if to split the processor in half. Previous to my recent cleaning, it was a small dab in the center. Both are giving same results.



Thanks again

Your heatsink is definitely the problem. It was just barely enough to keep an overclocked P4C (Northwood, not Preshott) cool, and those were single core.

 

[faxon]

yea im going to have to say the same. since you are probably looking for something which is easy to install and will still keep things reasonably cool at stock, and is cheap, i would say get an arctic cooling freezer 7 pro. only $26 at newegg and it has free shipping.

if you are looking for something a lot more hefty to learn to overclock with, get yourself a tuniq tower 120. this is (arguably) the best air cooler you can get for a quad that doesnt require any sanding of the base to get the performance required to cool a quad down properly. this cooler made the difference between an unstable 3GHz OC (under a gemini II) and a stable 3.6GHz OC on a G0 q6600 a buddy of mine is using (unlapped). that chip runs hotter than yours (65nm, higher voltages, and OC), and it loads at just above where yours is in coretemp, to give you an idea of performance. you can use the same method of applying TIM to it, but since it uses a bolt through kit i would recommend posting back here if you decide to buy it so someone (aigo?) can post as to the best way to mount one. i myself havent mounted one and aigo is probably going to have some super leet technique for putting it on i havent thought up yet.

Hey guys thanks for the info, i read a few reviews on newegg, and i just put an order in for an AC7, and some more Arctic Silver. Hopefully in a few days ill have some smaller numbers.

In the mean time, im going to relax my use a bit so i dont stress anything.

 

[faxon]

yea if you have another comp (like most of us here do lol), use it for a couple days. my main rig has been out of use for over a month now because i had to RMA my motherboard and i took the chance to do some extreme case mods (full paint job) while i was waiting on the board back. pics as soon as i get finished, my software for pulling pics off my phone (which has a good digicam suprisingly) is on my other comp LOL

 

[ViperThreat]

Hey guys, I just got the AC 7 pro installed, and im still seeing numbers in the hight 50s to low 60s, while idling. As I recall, there is a break in period, which will drop the temps a few degrees in a few days, but im still 30 degrees above where i feel i should be.


Its starting to get frustrating, as my laptop from which i am posting, is old and slow, making homework, work, and anything else a complete drag..

Any other suggestions?


EDIT: Heres a fun one for you.. I took the Fan off of the AC7, while in use, and the temperature didnt move.. Figure that one out for me.

 

[Drsignguy]

Check if you have the latest bios for your motherboard. You just might be in need of a flash.

 

[ViperThreat]

Just flashed the bios to p04, which I believe is the latest, and im still hovering at about 50C idle.

Im beginning to debate if maybe my motherboard is faulty.

The motherboard was purchased discounted for open box, it hadnt been used, and i saw no damage on it. It passed all of my tests once installed, and I figured its fine. who knows.

The Processor is an OEM, Didnt want to wait for the boxxed version. So maybe it could be at fault as well?

 

[Martimus]

This guide may help. After doing the things stated there, my idle temps went from 60-70C to 18-20C.

Your expectations are WAAAAAY to high (or low, maybe?) for a quad-core. Being in the 40s idle is a good place to be on air.

Sorry if you said it already, but is your Vcore on "Auto", or did you manually set it? Some boards over-volt.

WTF your CPU was running at BELOW room temperature? How the heck do you do that without a TEC or phase change cooling? Oh wait, maybe your software or sensors are wrong?

You guys don't just have way too high expectations, but UNREASONABLE expectations. You do realize that if the CPU is running at under 37ºC, it will feel COLD to you, right? Because 37.5ºC is body temperature.

I used to live in the desert, and on occasion the outside temperatures were close to 120ºF. That puts it at... 49ºC.

Aren't Core 2 Duo chips designed to be functional up to 85ºC or so?

 

[disports]

lol 18-20C? lowest I'm idling cause it's cold in my room is 28C

It was actually 15-17C for room temperature, so it wasn't exactly under room temp. But I highly doubt the thermocouples on the processor are meant to be accurate at that temperature range anyway. Even so, the coretemp measurments went for 60+ to 18-21 C at idle when I upgraded to a Freezer 64, but they went down to high 20's before that (with the old zalman) just by doing the steps outlined in that guide.

 

[Gillbot]

17 degrees Celsius = 62.6 degrees Fahrenheit

Is your room in a meat locker? I would say 21C is a fairly average room temp so an aggressive idle temp would be around 23-25C.

 

[Martimus]

I kept it at 62 during the winter, when I was having those problems.

Either way, I don't understand why people jump at low reported numbers. The thermocouple isn't calibrated for room temperature anyway, so why would you expect it to be accurate there?

Even if it is good to +/- 1-2C, you keeping your thermostat set to 62F doesn't mean an AIR heat sink can achieve AMBIENT temps.

 

[ViperThreat]

Well.. my last system, had a 4200+ X2 it, and it would idle at about 30-35C, Under load, it would be at about 45-50, and under extreme load (prime 95 etc), it would hit 60.


Since I seem to be idling at 60C, thats why im a bit concerned. With all of my previous builds, as far as I am concerned, 60C is something I should never hit, and considering the lack of stress on the system, im concerned about what stress might do.

Ill also add that my previous systems held these low temperatures, and were almost silent. Currently, my computer sounds like a small jet with all the fans on high.

@ Ocguy31
I have no need to overclock, so I have left the bios settings stock, besides my cpu fan speed, which I locked at 100%. I dont feel that my expectations are too high, 30C is 86F, which is 20F hotter then my rooms average temp. At idle, I dont see why thats unreasonable.


40C idle would make me happy, however im still quite a ways from that.

FYI - My Q66 @ 3ghz idles @ 35-40 loads @ high 40's with the ACF7pro, however, the HSF is isolated in a wind tunnel. Your 45nm CPU should be at least be low 40's @ idle depending on your weather conditions....

More importantly I think, is what is your load temps?

 

[ViperThreat]

Ok. i just completed a load temp Marathon, with just ventrilo, and world of warcraft running, i was steady in the 65-70 area.


Beddie bye time for me for now.

I'm just telling you what was reported by CoreTemp. I don't know what it is now, since I haven't had issues with heat since (So I don't measure it on a regualr basis). I read that the temperature sensor was only designed to be accurate within 5C at the thermal maximum. Who knows what it would be at ambient. Plus, who knows how accurate coretemp is? I used it as a tool to help me with my overheating problem (It would shut off after about 10-15 minutes consistently when I updated from a single core to a dual core.) It worked for that purpose. Yes, it gave me values far below what I expected. Enough that I actually overclocked my chip for the first time in years. But I never even thought that the values were spot on accurate, so what makes you think so? (also the value would jump from 17 to 21C, so it only had a precision of 4C anyway, each temp increase on the monitor was 4C, IIRC)

So then why are you believing those idle temps to begin with?

 

[ViperThreat]

Well.. i hate to revive my old topic, however just for closure, and anybody who may happen across this thread with the same problems:

about 2 weeks ago, my system froze, and upon a reboot, would not post, troubleshooting and all, simply no response. After testing the parts on other systems, i was left with the motherboard and cpu giving me trouble. a few calls to Intel and EVGA later, both my CPU, and motherboard are on a trip for RMA, both have been approved under defective product.

Both Intel, and EVGA reps told me:

The overheating of the cpu could have been a defect within the cpu, which eventually led to a core burning out (i didnt know individual cores could burn out.. learn something new every day). Anyhow, its possible that the core burning out caused ir-repairable damage to the Motherboard. According to the EVGA rep, the Motherboard should not have taken damage, however my troubleshooting said otherwise.

On another level, after describing the overheating Issues, the rep told me that i should see temps in the high 30s to low 40s at idle, with low to mid 50s under load. This is with the stock heatsync not included with the OEM processor. Intel does not support aftermarket heatsyncs (which in fact void the warranty. Mental note, buy OEM from now on.)

The good news for me is that the store i purchased the CPU from (Microcenter) no longer carries the q9450, however they have a 1 year warranty on the OEM processors. So they handed me a $350 gift card with which i promptly snagged a q9550, and still have $30 on the card. Cant beat that. My motherboard should be arriving here in 2-3 days, and hopefully all of my problems will be solved.

[polarbear6]

dude if the problems doesnt solve (like what happened with me) try undervolatging ur processor

it is recommended to run at about 1.225 volts something like that
i run at 1.218 volts
earlier even at idle it used to be around 50c (i dont use Fahrenheit ) now idle is arnd 40c

and on oc and on stress test it is arnd 58c for 3.0ghz to 3.4 ghz again mine is a dual core so try ur luck urs mi8 not be as gud as mine

ahhhhhhhhh chahahaha ALL THE BEST WITH THE NEW PROCESSOR
