Hello.
I just built my computer and checked to BIOS to see what the running temperature was.

What is a safe temperature for a Intel Quad Core Q9550?
Right now I'm at a constant 70-73.
August 29, 2008 6:39:20 PM

That's a bit high for idle temps and about as high as you'd want to see it go under full stress testing, even with the stock Intel cooler (which is fine for a non-overclocked processor but you'd want something better for overclocking).

If you are using the stock Intel HSF check to verify that everything is copacetic with the installation and that all the push-pins are fully seated. However, if you have to fiddle with it at all you'll want to pull it off and clean off the thermal compound properly and re-install it, properly, with completely fresh thermal compound.

...and if you're going to do that you may as well spend ~$30 on a decent HSF, such as a Xigmatek S-1283

Yeah, this is a tall recommendation without knowing the particulars of your scenario but your issue is rather common amongst the forum and the prescription is typically the same.

HTH, cheers.

Hmm.
Thanks.
I don't know, when I put in all the push-pins, two went in fine but the other two wouldn't get pushed in.

Why is this?

...and therein lies the problem. Your exsiting HSF is not making full contact with CPU's heat-spreader. Do yourself a favor, if you can, and consider something like this:

No, it's not free but it will offer very good performance and a secure installation.

I would expect your idle temps to be right around 50C. Go with Halcyon's idea...a good heatsink is nice to have to get temps within their expected range. I would suggest staying away from the heatsinks that use the push-pin method of securing them to the mobo. Some heatsinks, like the Xigmatek S-1283 have push-pins, but also have an option to buy the mounting bracket for the back side of your motherboard. Make sure you have room in your case for it though, it is a very tall unit.
August 29, 2008 8:24:17 PM

I would say replace your thermal paste. If that doesn't lower your idle temps, I would get a new HSF and maybe add some fans to your case. I got the Xigmatek HDT-S1283, a new intake fan, some artic silver 5, and the retention bracket for the Xigmatek. It only cost about $50 and it lowered my idle CPU Temperature by 53C (80C -> 27C). My CPU is the Q6600.

see it is things like this that gets me worried, i have a new Q9550 sitting behind waiting for tomorrow to be installed. also, problems follow me when i mess about with these things.

recently redid my thermal paste and then put the cpu fan on the wrong way round and couldn't understand why my temp were ~5C too high.

well i can always buy a new one, my AMD one has been a champ the last couple of years.


Ya, I found quad cores to produce a lot of heat. I wouldn't install it until I got an after market heat sink and some AS5 (if I had to do it again). However, I think if you just take your time, you can figure it out. It took me quite a while to solve my heat issues, but now I'm glad that I did.

I upgraded from a Pentium D -> Quad Core. The difference is amazing it was definatally worth it.
August 29, 2008 9:10:03 PM

StrangeStranger is a genius and knows it, he's being humble...but if he's having a weak moment we've got your back.

No matter what I do and what HSF's I spend money on and what TIM I use I cannot get my Q9450 idle temps lower than ~46C at idle, even when I have it underclocked to 1.6Ghz. ...but its been a solid processor and has delivered on its promise of providing exceptional performance. ...and your Q9550 is faster at stock yet...so enjoy. If you do need to buy an aftermarket HSF it'll give you some overclocking headroom that you may, one day, find quite useful.

So...Cheers.
August 29, 2008 9:21:05 PM

Really? Is that a core temp or tcase temp of 46C with the stock fan?

My Q6600 is idle at 2.4ghz (400x6) and my idle temps are 28-35C (edit* Tcase) depending on the ambient temp with a ZeroTherm NV 120. (1900 rpm)
August 29, 2008 9:42:12 PM

Its a Core Temp, and I'm getting that with a TjMax value of 95C from both Everest and RealTemp. So, if that TjMax estimate is good it could be that I'm an idiot and just can't install a HSF properly. My ambient temps are about 24C.

I've used a Xigmatek S-1283, a lapped TRUE, and now a OCZ Vendetta2 with OCZ Freeze TIM.

If the chip dies/fries I'll just get something else, but the processor is not in any danger so I've no excuse to spend more $$, oh well.

Anyways, back to the OP...who needs to either re-install his HSF or get something new that's decent....
August 29, 2008 9:50:23 PM

I wouldn't trust idle temps for the cores. But thats just me, and what the message says when you use realtemps test sensors.

Also since I've switched MB with the exact same CPU, I was using tjmax of 95C on my P6N (NV650i) which seem to be the right setting, and now on my DFI (P35) MB I have to use the 100C tjmax. If I use the 95C tjmax, my core temps are lower then my tcase. So that is one reason why I don't even trust core temp readings anymore.

The tcase works fine for me, and its easier to take a quick glance at it, when I know I need to keep it below 71C. :D 

But each to their own.
August 29, 2008 9:55:09 PM

Hopefully you'll never see 71C Tcase.
August 29, 2008 9:56:21 PM

:sweat: . o O (the highest I've seen for the summer is 64C with ambient temp of 85F)
August 29, 2008 9:58:42 PM

85F is pretty warm so if 65C is that warmest you've seen you're doing pretty good I'd think.
August 29, 2008 10:04:27 PM

Heh.. Just saying what the highest I've seen so far on my Q6600. That 64C was on my P6N when it was working.

61C is actually the highest I've seen on this new DFI MB.

But ya, the main 2 keys are cool air (70-78F) and good airflow. Last night, it did get cold, but the ambient temp near my case was around 75F:



So to me, it really doesn't have exactly how good the HSF is, but how much cool air you can give it. Other then that, its only going to do what it can.

Well, I tweaked the thermal glop a bit and now I'm at around 53-57 idle.
Is that acceptible for a Quad Core? Will it overheat when I play Crysis or something? I'm not planning to OC.

Okay, it's now capping at 65.
Is that safe?
August 30, 2008 1:08:47 AM

Is that cores or tcase?

See thats just it, if people would go by the tcase, it would make things more simple. All ya need to know is the thermal spec from Intel, which would be, 71.4C, and to keep it below that would just be simpler to remember.

As far as core temp on idle.. blah.

How do you find the tcase?
All I'm using is the BIOS temp monitor.
My hard drive didn't arrive yet =(
Is 65-66 idle safe to run or should I tweak with the grease?
August 30, 2008 1:17:33 AM

That would be the tcase sensor, which the bios uses.

So that is abit high 65C.

I can tell you its not the grease, but rather one of the 4 pins you push in that isn't secure. That is if your using the stock HSF.

It should be around 30-36C. 36-40C if your ambient temp is warm (80F+). since its in the high 50 to 60s, its more of a HSF installation problem.

Thanks a lot.
I've just adjusted the pins and added a bit more grease to the actual chip.
I'm still at 54 C.
What else could be the problem?
August 30, 2008 1:29:04 AM

You shouldn't need to add more.

My advice:

1) shut the system down.

2) take the HSF off

3) clean off the top of the CPU and bottom of the HSF

4) Rotate the black handle the opposite of the arrow, ensuring the black pin is out of the white clamp on all 4 pins.

5) Reapply the thermal grease only on the CPU according to the instructions. Only a dab (size bb), then spread out on the IHS evenly is all it should take.

6) when placing the HSF on the CPU, make sure the white camps go all the way through the holes.

7) keep a some pressure (enough but not to bend the MB) on the center fan, and pushing down on the pin that gave you the most trouble first.

8) power up and hope its in the 30-40C.

Edit:

When you've tried that, can you also tell us what the vcore is at? It shouldn't exceed 1.3625V, but it can be well below that.

Well, now it boots at 45C, and the Vcore is the cpu Core I'm guessing?
It's 1.12 V
August 30, 2008 1:48:04 AM

Sounds allot better, I'd say 45C is allot better then what you were at. Perhaps the airflow is not quite adequate enough for the 30's.

Other then that, I'd say its okay now. You just need to get the rest of the system put together.

Thanks.
The temperature rises to about 50 after a half minute though.
I have everything but the hard drive in the case, maybe I have too many cards installed.

EDIT - Is 45C-50C safe for usage though?
I'm scaling to about 55 after a while.
August 30, 2008 1:53:23 AM

Hmmm... might wanna leave the side panel off when you do the actual windows install. Giving the HSF enough cool air should get you on a good start. If you do have allot in your PC case, might wanna work on good cable management, and figure out a good airflow for the fans.

What PC case did you go with?

The CoolerMaster Cosmos 1000.
I'm working on the wires now.
I'll try that, redo the thermal grease, and try again.
August 30, 2008 2:05:50 AM

Ah.. Cosmos.

Its airlfow design may not work well with stock HSF, in my opinion.

But if you want to try this, it's airflow design is mainly bottom up. It does have a rear exhaust as well. But since you have a HS that blows downward on the MB, all you have is heated air from the bottom, since its cool air but heated from other components by the time it gets to the HSF.

Call me crazy, but try using to top exhaust fans as intakes for an experiment. The rear exhaust fan should be adequate if you can turn the top fans to a lower RPM.

August 30, 2008 2:07:20 AM

How would you do that?
Just lower the RPM?
Or reverse it or what?
Lol, I'm a noob.
August 30, 2008 2:08:59 AM

To reverse it, you would need to physically take the fan out and turn it around (basically flip it). If the fan has a controller (some have a knob to turn, or switch high/med/low).

Just experiment with it, just to see what works best for it.

Edit:

I use a CM 590 case, and use one of the top fans as an intake for my E4400 setup.

I can't find a switch, so I'll try flipping it.
Thanks.
August 30, 2008 2:26:23 AM

Just to clarify, the switch or knob is to control the rpm or how fast the fan spins, not to reverse the airflow. :oops: 

If you look at the fan bracket, it sometimes shows an arrow on the plastic, indicating how the air travels. Some fans don't.

Usually when you see the open face of a fan, where the sticker on the center spins, that would be the intake side. On the opposite where you see more of the bracket, is the output side:



So you can see that the face of the fan is shown as an exhaust, or air is being pushed out.

Well, I just flipped those two fans so that the air is now coming in.
It doesn't show much of a difference in temperature.
Maybe I'm doomed to failure =(

Well, the negative pressure is now positive, but is negative cooler than positive?

Maybe I just need a better heatsink?

45-60C is high...
As long as it doesn't burst into flames I'm fine. :)

The Thermal Specification is the CPU temperature right?
So as long as it's under 71.4 I should be fine?

Edit - With my air conditioner on, the temperature is slowly going down from 53 to 52 to 51 now.
August 30, 2008 2:49:34 AM

Yes, 71.4C :

Q9550

edit:

I would recommend getting a 3rd party HS with a back plate, which does require taking the MB out of the case.

Thanks for all your help, Grimmy.
I think that although my proc isn't running at an optimal idle 30C, it's running at a safe enough 48-50C.

I just hope it won't blow up during games. :p 
Thanks again.
August 30, 2008 2:54:55 AM

No problem.

The reason why I was talking about Tcase earlier, if you read around the forum, most people end up giving core temps, which is based on a different sensor, and for idle temps, they really can't be trusted. I didn't know you were going by the bios temp. :lol: 

As far as blowing up... Na, it should shut down if it gets too hot. It does have a thermal trip to where the power is cut off from the whole system. If that happens just let it set for about 5 mins, then turn it back on... if you get the far. :p

By the way, the VGA Air duct decreased the temp another 2C.
Just a tip for anyone else who has the Cosmos 1000.

THANKS AGAIN GRIMMY!
August 30, 2008 3:09:54 AM

The other thing I should mention, is when windows is finally installed, you should have even cooler idle temps. Again I'm talking Tcase temp. You can use SpeedFan that shows either CPU or it maybe labeled Temp1/Temp2/ect, you just need to figure out which one it is. The MB app should help indicate that as well, as you can see from the pic I post above for my DFI LAN DK MB.

The reason for that is speed step. So don't freak out if you use CPU-Z and at idle, the CPU speed is 1.9ghz or 2ghz. When you put a load on it, like running a game, it should climb back up to 2.8ghz

Other then that.. GL on the new build. :D

Hi all Guys

Few days ago I've put together xfx 750i SLI + q9550 processor together, everything is ok but temps from cores are different.

I applied MX-2 compound
and cooling fan is Freezer Pro 7


in idle i get
core 0: 37C
core 1: 25C
core 2: 38C
core 3: 37C
core: 37 (that's average temp or what?)
Readings are from SpeedFan 4.37


Can you tell me if above temp are right for this processor with this mobo ??


a b à CPUs
January 4, 2009 4:15:39 PM

Looks about right IMHO, although I would be a little concerned about the sensor for core 1.

January 4, 2009 7:27:04 PM

I can see in Real Temp temperature on core 2 is 38C constant.
Also after i did check of sensors with above Real Temp i can see it showing me 0 value on sensors. It's mean my sensors stuck every time showing me 0 on different ones.



I already thing about returning this processor.

Some advice please guys.

Hy guys i have a quadcore 2.4GHZ cooled with a Zalman cooler with fan speed regulater at 900rpm my temp is at 41c and at 1700rpm it is at 32c-36 c i have a question at what temperature the processor is burned? :ouch:  can someone reply please thx
July 23, 2009 6:23:18 AM

I see it's been several weeks since you asked so I hope you found an answer but if not.....

Your particular processor, the Kentsfield, comes in two flavors; SL9UM and SLACR. Being 65 nm units they both run pretty hot. The max for the SLACR is about 70c and it needs a tdp 95w cooling system. The SL9UM tops out at 60c and requires tdp 105w cooling(or so intel claims).

This doesn't mean that they're ruined if they exceed their max. As the cpu approaches critical temperatures it begins to flood the BIOS with warnings. At a certain point your system will just shut down. To do actual permanent damage your cpu would have to reach about 120c before the power trips.

Your temps really aren't bad but they are a little high. I'd ditch the Zalman, which may look neat but really isn't very effective. A better choice in the same price range would be a Scythe blow-through style. They're hideous in a way only japanese hardware can be but they do work extremely well.
