Intel Q9450 Quad Core Temps High?

I’ve been reading around and I’m still not sure if my temps are normal or not…My build is in my sig but I’ll post it anyway.

COOLER MASTER Centurion 5 Case
Intel Core 2 Quad Q9450 Yorkfield 2.66GHz LGA 775 95W Quad-Core Processor
ASUS P5K-E LGA 775 Intel P35 ATX Intel Motherboard (w/o built in wifi)
EVGA 512mb GeForce 8800 GT 512MB 256-bit GDDR3 Graphics Card
CORSAIR XMS2 DHX 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)
Western Digital Caviar SE16 640GB 7200 RPM SATA 3.0Gb/s Hard Drive
CORSAIR 650TX 650W (MFG. by Seasonic)
Tuniq Tower CPU COOLER.

Anways, my original ram was bad and I finally got a new batch so I’ve testing this baby with Prime95,memtest, and many temp progs to see how it performs. I had it on for almost 24 hours and there were absolutely no errors or problems in any of my tests…except one.

I’m using a Tuniq Tower 120 and for some reason I’m still getting high temps. Or at least what I presume is high compared to all of the threads I’ve read. So tonight I tore the entire computer apart, back down to the motherboard on a piece of cardboard and proceeded to clean the heatsink on the tuniq tower and the top of the cpu with Alcohol.

After I was done, I remounted and put it all back together. My results were that my temps improved a few degrees but not much.

My first time mounting I put a lot of Arctic Silver 5 and didn’t mount the tuniq tower very tight. The Second time, tonight, I put a very small amount of arctic silver 5 on the cpu only and mounted it as tight as it would go without breaking the board.

Here are my results in a jpg you can view. Please let me know if these temps are really high for an Intel Q9450 QUAD CORE STOCK (NOT OC’D)

As you can see, my load is zero and when I ran prime95 for a half hour, the temps averaged around 65-67 degrees Celsius on all cores…

For some reason every one of those temp programs tells a different temp and I’ve heard that speedfan is terrible for quad cores so I only added it as another point on my temps, compared to the rest.

I made sure to spread the artic silver 5 very flat using a plastic bag. I stayed away from the edges and only put a rice sized piece right in the center. Only after I put it all back together did I read that I shouldn’t have spread it at all but just mounted the tuniq tower and let it spread by itself.

All the advice, concern, or encouragement you can give will be taken to heart and greatly appreciated!

Thanks in advance for your help!

P.S. I have all of the fans in my case on 100 percent. It sounds like a jet…lol

Edit: Room Temp is 79.5 degrees.

Edit 2: Here’s a pic of the temps after only 7 minutes of PRIME95

Temps are within intel spec.

Saying that however, try and remove the side pannel from your PC and point a fan in it to see if your high temps are due to poor airflow inside your case. If the temps drop down then you need to work out how to get more air through your case.

One thing to remember is that a quad core has, in effect, 2x core2duo chips inside it so double the heat output of a similar spec dual core CPU. Just make sure you have used the correct ammount of thermal compund (remember, to much actually works as an insulator and increases temp) and that the mounting for the heatsink is correct.

Those temps are a bit high, but comparsion to that of other owners of Q9450.

Typically idle temps should be in the 40-43 range with an overclock.

The Tuniq Tower 120 can be a little tricky to mount. I would remove the cooler and re-mount after a fresh application of quality thermal compound.

The application of Arctic Silver is specific for different CPUs. Please refer to the web site for proper application of the Thermal Compound.

Carefully apply Arctic Silver 5 directly to your quad core heatspreader. Only apply thermal compound to the top of the actual CPU heatspreader and not the heatsink. The red line in the photo at left depicts the amount and size of Arctic Silver 5 to use. Be CAREFUL to apply the thermal compound in the CORRECT direction. To apply a thin line of thermal compound in the correct direction, do the following: Make sure to orient your CPU heatspreader with the triangle mark on the chip pointing down and to the left like the photo.

I just don’t understand why the temps are so high on mine. As I said, I completely stripped the system last night, put a very small amount of Arctic silver on the chip, used a credit card to make it as flat as possible, mounted the tuniq tower pefectly, and mounted it as tight as it would go and no matter what, my temps are really high. I even removed the side cover and tested it with no change. The tuniq tower doesn’t feel warm at all. I don’t know what’s wrong but it’s really bothersome…

Edit: Idling with a fan blowing into the case the temps are: 39,36,43,43. Still not that great…

I thought the tuniq tower was supposed to stay around 29-36 degrees…?

If your room temp is 80 deg then I would expect higher temps. Ambient temps have a lot of influence on the CPU temp. Next time you have your cpu cooler off you may want to check and see if your cpu and heat sink surfaces are flat. If there is a dip or void it will not dispate the heat from the CPU properly. Also is there anyway to mount a 120mm fan to that cooler?

Well, there is a 120mm fan inside the Tuniq Tower. It’s turned on all the way to 100%. I could probably find another way to mount another fan to the cooler but I don’t know if it would help because I placed my fingers on the Tuniq Tower, where it connects to the CPU and it was only slightly warm.

Next, I oc’d the cpu to 3.2ghz on all four cores to see if there was a temperature change and it only went up about 1 or 2 degrees celcius. Oc’d these temps are somewhat normal. I went to the thread Nemesys posted and a few people on there were reporting temps very close to mine. The majority who had really low temps (20s-30s) had water cooled systems. I don’t think 44 degress celcius is all that bad for an oc’d cpu on idle, do you? The max temp it’s reached in one hour oc’d on Prime 95 is 65, 59,62, 61. That’s still 10 degrees celsius lower than Intel’s specifications.

I think I might just try to water cool this setup sometime in the near future. And considering the fact that it stays pretty close to around 55c on most of the time. That’s okay isn’t it?

Are you running small FFT’s because that is what will create the most heat. If you increased vcore for 3.2 Ghz it sounds like the Tuniq Tower is doing it’s job if your temp only increased slightly.


So first of, you can’t compare your temps to those in xsystems unless your using the same temp program they are using. this is because each program can use a different Tjmax value. Your coretemp prog uses 105C as Tjmax, which is the highest of all of them, so the temp it calculates will also be the highest. Also note that the people on xsystems don’t tell you what type of cooling their using, usually you can tell if they are using water but not always.

Your PC is already very fast, so I wouldn’t be in such a rush to OC it right away. Maybe do more reading on it to understand using the fsb: dram dividers and the limitations of stuff, so that you don’t fry your ram and such.

I don’t think your temps are high, since others have the same temps, and I think this is a limitation of the software used to calculate the temps. So I think the actual temp is much lower, maybe 20-25C lower than what its reporting.

If you want to water cool it sometime in the future, check out
They have great customer service and good prices/selection too.

Hey thanks guys! Yeah it’s 7 and a half hours later and my temps haven’t changed at all since what I reported earlier and Prime95 is still running strong.

I don’t ever plan on ocing any more. 3.2 is what I was after and I am completely satisfied with it. Right now, my Fsb:Dram is 1:1 or in synchronous mode. Here’s the readings from cpu-z and Realtemp:

Anyways, let me know what you think…


Looks good, enjoy it :smiley:

When the q9450 price drops and a new stepping comes out I think I’m going to get one. :cool:

Thanks alot eric93se! Yeah it went strong for 9 hours and 20 minutes and I finally stopped it. ZERO ERRORS, ZERO WARNINGS. PERFECT.

So I checked the temps and they dropped almost 20c instantly. That’s pretty good. I love this pc and I do think you should get one when the price drops. It was a little expensive but I am completely satisfied. It runs all my games perfectly without any glitches, my video editing, etc. Awesome PC. Thanks for your help building it man. You rock!

If you already have a good PC then I would wait till the end of the year. Intels new chip is out then and is supposed to be 30% faster clock for clock plus it supports hyperthread and will come in 2, 4 and 8 core (4, 8 and 16 threads) when fully released so should be a good performer, shame it will mean a new mobo and new ram for most people (new socket and DDR3 ram only with dual or tri channel)

I don’t think the consumer parts will be available till '09, probably server stuff will surface the end of 08.

What we really need is better operating systems. Not the garbage microsoft keeps dishing out. Linux keeps getting better and better while MS products are getting slower.
