E6600 overheating madly!

August 18, 2007 3:26:19 AM

First of all, here are my specs:

Intel C2D E6600
2GB PC2-6400
ATI X1900XT
535W ENERMAX
All at stock speeds

Now, the problem I have is that my CPU is running extremely hot and I have no idea why this is happening. I have checked the temperature of it with many programs, including Core Temp, SiSoftware Sandra, RightMark CPU Clock and TAT, and they are all showing that the temperature is around 75-80. I have looked around in my case and the airflow is fine and is fitted with 2 120mm fans and 1 90mm fan with the stock heatsink. The air is cool inside but when I touch the heatsink, it is boiling hot and I have no idea why. Can someone help me out with what I can do to resolve this problem, perhaps get new 120+90mm fans and heatsinks, if so, any reccomendations? Thermal paste? I really don't know..

My knee-jerk reaction is that your HS is not mounted properly, or if it was, it has come loose.

Is this a new build? If so, reseat your HS. Take the mobo out if thats what it takes to do it properly. If it was running cool then lately has goten hot I would definatly say the HS came loose in a move of the case or something. Have you taken or moved the case lately?

I mean really the only think that makes your temperature too hot is poor cooling. Case ventilation is not going to drop you 20C which is where you really want to be. So you need to examine the HS mounting very carefully.

It's not really a new build (around a year old I guess) and now is really the only time I started monitoring temps and stuff as I was wanting to do some overclocking. I have already checked that the heatsink is mounted properly and it seems that it is on securely.

Ohh wait one more thing. Are you running ALL those programs at once or are you checking then shutting down each program individually. I have read about problems arising when running several temp monitoring programs at once.

Also try one more program. run SpeedFan (by itself) and what does it read. You also didnt mention if these were "load temps I assume".
August 18, 2007 3:49:29 AM

You say its stock, so it not a matter of high voltage or OC. That basically narrows it down to roughly 3 possibilities:
Improper cooling

Improper software readouts: TAT and coretemp WILL read 15C too high on my E4300

bad thermal diodes

well bad diodes is not really an option since ther is NO WAY for software to directly access the CPU's thermal diode. The CPU doesnt have the capability. period. Also the fact that your "touch" of the HS tends to indicate that the HS is hotter then hell, and so therefore the software readouts (approximate guesses) are roughly correct.

So is the HS's fan operating? Are the fan or HS fins dirty? If not, I HIGHLY recommend removing, cleaning, reapplying thermal paste, and remounting the HS.

If its a matter of software, ie TAT or coretemp reading 15C too high then -15C would put you at about 65C which ....ehhhhen might not be unreasonably high for loads with stock cooling. 65C is a bit warm. Check BIOS to "BE SURE" your core voltage is at 1.325 or whatever stock V. is on a E6600.
August 18, 2007 3:50:20 AM

No, I'm running them all seperately, closing, then running a different one. I've tried speedfan and it comes up with the same temperatures again. These temperatures are just normal temperatures when I have nothing running.
August 18, 2007 3:53:01 AM

Yeah, the HS fan is operating fine and the fins look fine but I guess I will give it a quick clean and find some thermal paste to re-apply. What should I use to clean the HS? Also, is the CPU recieving damage thanks to this immense heat or is it fine?

clean it with some isopropyl alcohol. Use a 90% minimum if you can.

Your CPU will throttle back before it damages itself but the high temps certainly cannot be good. It does have an internal "shut down" threshhold temp to prevent temp burnout. 70+C idle temp can only be cause by improper heatsink somethingl.

Do you have a digital camera? Pull the HS and take a picture of both the CPU and HS bottom.

Its got to be a bad contact between the CPU and the HS. Either from bad or non-existant thermal paste, extreme concave of either or both CPU or HS, or in all likelyhood one or more of the plastic mounting pins is compromised.

Its gotta be a bad mount. There really isnt anything else that I have ever heard of that causes extreme temps.

you clean the dust? u need to post more specs - your voltage must be high? or amps high?

3 thinkgs no cooling, too high volts or too high amps - possible rouge programs making your cpu run all day

any new programs reinstall or try a roll back to pre problem
August 18, 2007 1:54:17 PM

I took out the heatsink and it had a lot of dust inside it, so I took out much of the dust and put it back in, however I didn't have any thermal paste to put on. I've run some of the programs and they are now at 85/83 for CPU0/CPU1. What the hell?
How would I go about posting the specs for voltages / amps?
August 18, 2007 1:59:39 PM

If it's a problem with the heatsink, can't I just get a new one to replace the stock one and then clean the CPU, re-apply thermal paste and put on the new heatsink? I was reccommended the Thermalright Ultra-120 heatsink, do you have to take the motherboard out to put this heatsink in? I was also thinking of getting a couple of Zalman ZM-F3 120mm fans to replace my stock fans which are kinda crappy. This would surely sort my problem?
I just checked RightMark CPU Clock and it's saying CPU core overheat detected - 99%....
August 18, 2007 2:34:11 PM

Turn off your computer right away and do not turn it on again until you get some thermal paste! You could ruin your processor by running it without thermal paste. Clean heatsink fins with a vaccum cleaner or air compressor and clean the base and the heat spreader on your cpu with 90% alcohol. Apply your new thermal paste according to the instructions included with it. Make sure that the pins on the heatsink are properly engaged to the motherboard. They can be a pain in the butt to get them locked down properly.
August 18, 2007 2:51:48 PM

I have just ordered a new heatsink, the Thermalright Ultra-120 with a couple of new case fans, some thermal compound and a CPU/heatsink cleaner to get rid of the current thermal compound on the CPU. Am I correct in thinking that I should first remove the stock heatsink, then clean the thermal compound on the CPU (how am I meant to do this correctly? remove the CPU from the bit it's in then clean it softly? how would I dry it?) After this I put some fresh new thermal compound on the CPU and place the new heatsink on? If someone could confirm this order to do it in for me, I'd greatly appreciate it. Thanks!
August 18, 2007 3:14:43 PM

Just take a soft cloth and dampen it with the alcohol or cpu cleaner that you ordered and wipe off the top of the cpu. Do that a couple of times until the cpu is cleaned.The cleaner will evaporate on its own. You do not have to dry it. You do not have to remove the cpu from the motherboard to clean it! Other than that it looks like you pretty much have the proper order for replacing the heatsink. That Thermaright heatsink is awesome from the reviews I read (go to Frostytech website for review) your temps should drop by at least 50% if not more!

just gonna toss in my 2 cents here. make sure there is no fan control on.
since most boards do not read from the core, they read from the socket(LGA in this case) they read much cooler. then fan controls keep the fan slow and let it warm up.

Hell my quad fan wont even spin up until the system get going(i am gonna fix this, but the temps where stupid low then, like 27-30c cause the room was 18c and speedstep is on).
August 18, 2007 4:14:50 PM

You need to list your BIOS settting in regards to your CPU settings ie. FSB, CPU multiplier, core voltage. You say stock but have yet to list what "stock" is on your board. We need to know this information before any definative answers can be given. But I still think its a mounting problem with your HS. I mean everyone "thinks" they mounted it correctly, but there are thousands of threads just like this from people who in fact did not mount the HS correctly. Hell Im a rock solid 6'4" 225 and I had a hellofa time snapping the plastic push pins on my ninja down. I thought for sure I was going to break them or the board for sure.
August 18, 2007 5:07:59 PM

Thanks for all the great help guys, I really appreciate it! I'm going to have another go at pushing the pins of the HSF into the motherboard, I guess I may have not been using enough force, does it make a difinitive click once it's been pushed in correctly? As I really want to be able to use my computer before the stuff arrives on Tuesday-Wednesday. Does anyone have any experience with the Thermalright Ultra-120? Do you need to take out the motherboard to install it or not? Also, you have to install a 120mm fan onto that particular HSF, is that correct?
Thanks again for all the great help.
August 18, 2007 5:11:35 PM

Oh and yes, I have listed my specs in my first post and I haven't done any OC/ing or anything so they should be at stock settings, whatever the stock are for them.

Thats my point. It seem that YOU dont even know what your setting are. Hell your core voltage could be at 1.7V and you wouldnt even know it. You need to go into the BIOS and get that information and LIST IT HERE:

Hell for all we know your brother got mad at you and sabotaged your BIOS so as to fry your computer. How the hell could we possible know any different until you actaully tell us what all the freq's and voltages are
August 18, 2007 6:19:02 PM

Ok, I'll go and check that out, but I thought I should keep my computer off until I sorted this temperature problem out? Or is that just for people who want to be extra extra careful? Would it be OK for me to use the computer at this state? And FYI, I don't have a brother. :p 
August 18, 2007 6:25:47 PM

Also, can you tell me what I should list from the BIOS so then I can come back here and post exactly what is needed.
Thanks.
August 18, 2007 6:29:25 PM

What motherboard are you using? I know that some asus boards are known for over-estimating Vcore and will sometimes run a bit hotter with all setting to auto. I recommend you set everything manually in the bios, gives you a way better idea of where the levels are compared to the auto setting.

I definitely agree with everyone that you should re-seat your heatsink and properly use TIM.

August 18, 2007 6:49:33 PM

Could be a faulity sensor on ya mobo, did u apply thermalpaste?
August 18, 2007 8:03:45 PM

start with:
FSB
CPU mutiplier
V. Core (CPU voltage)
August 18, 2007 8:09:21 PM

I'm using the ASUS P5W DELUXE motherboard. OK, I will go check out all the things you have mentioned and will post back here.
August 18, 2007 8:20:34 PM

OK, I just went and checked the BIOS for the settings which you told me to check.
FSB - 1066mhz
CPU multiplier - Auto
Vcore - Around 1.3V

I also saw that before I entered the BIOS, it said CPU fan error; press F1 to continue.
I also saw that CPU Q-Fan control was enabled as I heard this effects your fans badly or something.
August 18, 2007 8:29:22 PM

So your FSB is set to 266Mhz in BIOS? what does speedfan say your V. Core is or use some other program.
But it apperars everything is normal and you simply have to get your HS either cleaned properly or seeated properly.
August 18, 2007 8:38:49 PM

artic sliver 5 is the recommended Thermal paste by be (and most ppl)

it sound like CPU HSF fan ios dodgy or not connected properly or more likely you feed it too much voltage. it should be around 1.3, if so and you have contiuning problems lower it.
August 18, 2007 8:42:08 PM

It says my Vcore is around 1.3V, fluctuating from 1.2-1.3V mainly. This is the question I mainly need to know;
Will the new heatsink (ultra-120) and thermal paste and new fans fix this problem for me? IE get my temperatures down to what they should be? (40degrees and less?)
August 18, 2007 8:51:43 PM

Assuming you do not have a defective IHS, your current stock HS should be able to keep your idle temps at or just above 30C
August 18, 2007 9:04:06 PM

What does IHS stand for? We still haven't been able to work out why my CPU is running so bleeding high.. <_<
August 18, 2007 9:58:24 PM

The Integrated Heat Sink on the CPU. Its the metal plate on top of your CPU with all the CPU info etched into it.

See the actual "die" (silicon waffer piece that comprises the actual CPU) is underneath the IHS, and the IHS makes contact with the die underneath so as to transfer the heat to the heat sink that you mount on top of the CPU.
August 18, 2007 10:13:59 PM

Cheers for that.
Well, lets all hope the new heatsink sorts out the problems, eh? Do you think it's likely to do so?
August 18, 2007 10:23:22 PM

My recommendation is to figure out the problem before simply throwing hardware at it. If that means taking the MOBO out and inspecting the HS clips..... thats what I would do. My point is that if your not able to mount the stock fan correctly or diagnos the issue with it, what makes you think you will have better results with a different HS? Have you removed the mobo and inspected all 4 mounting points so as to know if they are working for sure or not?
August 18, 2007 10:29:04 PM

I will take out the MOBO and inspect when the stuff comes, so I wont have to do it twice. If there is a problem with the mounting points, how would I resolve that? Is the only way RMA'ing and getting a new one or?
August 18, 2007 11:13:19 PM

OK, first thing to realise is that if the Heatsink is HOT, then the thermal interface material, and the bond between the HS and CPU is AOK.

When the CPU says "OUCHIES HOT" but the heatsink is NOT hot, then that is the indicator that it is mounted badly, and/or the thermal interface compound is badly applied.

The hotter your Heatsink is the better. The only time your heatsink should be cool is when the CPU is idling.

If your heatsink is hot during idle (i.e. under 5% CPU usage) - then you have a problem, and a tricky one.

One thing which forced me into an XP rebuild recently was a rogue Windows Update which left the system using 95% of the CPU - even though Task Manager reported 5% CPU usage! Using CPUMON - a third party CPU measuring tool, it consistently reported 95% usage...

Damn weird, I know. It could also have been a virus or scumware which could not be identified by Norton, McAffee, Adaware or Spybot...

Under normal circumstances the onylo way a CPU *AND* heatsink can be hot is when the CPU is running hard.

Have you activated speedstep - or whatever the CPU throttling software is? Is it on by default? I know my athlon runs cooler in normal mode when the throttling is enabled: it drops from 2400 MHz to 800 MHz when it's not working hard. I have a totally passive Thermaltake Sonic Tower cooler and it is cooler in idle mode when the CPU is at 800...

Crumble, Mobius has the right of it. If your Heatsink is too hot to touch then it is making correct contact with the Integrated heat spreader.

From everything you have mention in the above posts you have correctly seated your stock heatsink. If you are running that hot at idle there are only two things that could be causing that. 1. Your system is running close to 100% with a low fan speed. 2. For some reason the processor is running with a very high voltage, much higher than what you have been reading.

If you have a digital thermometer that you can stick on the heatsink and take a direct reading that would give us a actual positive number for how hot the heatsink is getting.

If your processor did overheat then it would cause the board to turnoff. You would get a thermal shutdown. Since you have not seen that you have not reached that temperature. That does not mean that the processor has not used the Halt clock command to reduce heat either.

I am really interested in how hot your heatsink is getting.
August 19, 2007 11:54:25 AM

I am hopefully getting someone to check all this out for me over the next few days, ready for when I change over some parts, then I will report back here with my knowledge.
Thanks alot.
August 20, 2007 12:13:31 AM

Way back in the day I had a huge airbubble under my heatsink. I mean it prevented contact on like 75% of the middle of the heatsink. And what was happening was that the CPU was running very hot. The HS would eventually get super hot also. But it just took a long time for the HS to heat up but eventually it heated. Its like the small amout of contact was preventing the CPU from dissipating its heat fast enough so there was a heat build up in the CPU. But after like 10 minutes or soo the HS would finnally heat up to a high temp also.
August 20, 2007 8:06:07 AM

My temps were almost identical to yours when my heatsink got loose.

Like others said you should probably use a cleaner to take the paste off your CPU, however I just used a plain paper towel and my temps are fine (considering my computer is in a 80 + degree room with no air flow, 35 is pretty good :p ).
August 20, 2007 9:43:44 AM

All I have to do is remove the thermal paste from the CPU? Not put any more on?
August 20, 2007 3:16:29 PM

I meant remove the paste already on the CPU and put some fresh thermal paste on then the new heatsink?
August 20, 2007 3:59:38 PM

remove the old and replace with new. Yes.
August 20, 2007 5:55:13 PM

Alright thanks.
