cpu overheat problem.. :-(

[fto dude]

hey guys.. a bit of help if you wouldnt mind...

im a bit of a newbie so please dont take my ignorance as actual ignorance...

i posted up in general about 2 weeks ago about a system i saw for sale on the net.. and you guys pointed me away from the mass retail type system and instead to pay a bit more and get a decent bespoke system from components or a member on here.

as it was.. i found one that satisfied my requirements and stretched the budget a bit and found one from a member here.. here are the specs of the computer...

Intel Core i7 920 D0 Stepping 2.66GHz Retail
Asus P6T Motherboard
XFX ATI Radeon HD 4890 XT 1024MB
OCZ Gold 6GB (3x2GB) DDR3 PC3-10666C9 1333MHz
Corsair TX 650W ATX SLi Compliant Power Supply
Antec 300 Three Hundred Ultimate Gaming Case
Seagate Barracuda 7200.12 500GB SATA-II 16MB Cache
Akasa AK-967 Nero Direct Contact Heatpipe CPU Cooler
Pioneer DVR-216DBK 20x DVD±RW SATA Dua
Seagate Barracuda 7200.12 500GB SATA-II 16MB Cache
Akasa AK-967 Nero Direct Contact Heatpipe CPU Cooler
Pioneer DVR-216DBK 20x DVD±RW SATA Dual Layer ReWriter
Netgear Wireless USB adapter

anyway the pc arrived today and so set about putting the image together. i have windows 7 32 and 64 bit to use.. but i was told it should run 64 bit ok.. so this i shall start with.
the pc arrived and the akasa nero heatsink was limp.. attached by the bottom 2 clamps but the top two and screw had come loose in the case.. so i detached it and re-screwed in the top clamp and then attached to the cpu.

anyway.. sorry to go on.. but basically the pc keeps shutting down and its because of an cpu temp error message..

"CPU over temperature error!
press F1 to continue"

then i press f1 and the windows disc starts again as if it had never installed before..im assuming because when it gets to the part that it needs to restart, this interrupts the installation process....
if i dont press f1.. nothing happens.

so in short. it wont boot up properly because of the cpu heat/temp message

any ideas please folks.. it was fully tested before, and fully working.. i dont know how he cpu could be so hot with 4 fans and not being used under proper load?

thanx in advance

Did you clean both the HS and CPU and re-applied TIM prior to re-attaching it? This could be what causing you issue.

 

[fto dude]

tim?

is this thermal paste?

 

[Ginger-Menace]

it is thermal paste, if the seal has been broker (which it probably has ) you will need to clean and re-apply new paste

 

[fto dude]

ok ill give that a shot thankyou..
i did notice the paste on the surfaces of the heatsink and the cpu... like a grey paste.. not solid.. but very.. well pasty by substance.. so get some and re-apply this

thanx

 

[fto dude]

thanx for the advice... ive re-applied the thermal paste now to heat sync and the chip...
ive re-installed windows 7 64 bit and installed 'core temp' to keep an eye on temp and cpu-z.

my cores are averaging 38-42 degrees... 2 cores are usually about 41, and 2 cores about 38. is this normal would you say?

thanx

[Sayso]

not great temps for stock.

 

[fto dude]

what does this even mean ?? ^^^

 

[wildman]

roughly translated I think it means sayso is saying that for stock speeds your idle temps seem a little high

 

[belial8321]

fto that grey paste is probablic arctic silver thermal paste and i do agree with sayso, that does seem a little high, im experimenting with the stock cooler for my 1055T atm and i have a HEAVY overclock on it (2.8ghz stock -> 4.4Ghz, idling around 27C

The i7 does tend to run hotter than most but I, for example, am running an i7 950 O/C @ 4.2Ghz and that idles at around those temps with the H70 water cooler and I still think thats too high.
You idle temps will also depend on you ambient room temp. The real test is what it's doing under load.
Perhaps run Prime95 ot Intel Burn Test and see what sort of results that give you in Core Temp.

Just noticed that, you only apply it to the CPU, the HS will take care of itself when it comes in contact with the CPU, maybe too much TIM now causing the temp issue? If you applied some to both parts.

 

[fto dude]

oh right.. ok ill have another look and take some paste off.. now the idle is more like 32-35 idle when i turned monitor on this morning.. maybe that still is a bit high for absolute idle.. no problems to report with performance tho...
do they tend to fluctuate between themselves.. ?

thanx for the advice guys..

YOu need to
1) CLEAN OFF ALL TIM using a tim cleaning product or as some use an alcahole based cleaner i prefere personally using AKASA TIM clean
2) re apply NEW thermal past (tim) to JUST the cpu (google how to apply thermal paste it will come up with lots of guides) DO NOT USE YOUR FINGERS TO APPLY TIM use a tiny rice grain blob or like i do an X shape on the cpu

Only apply to the cpu as when the heatsinc fit it will create the bond
i use TX3 NON condutive but i would suggest AC5 for you as it is all new to you and that is easier to use

the problem with seating the block on the old paste is that it wont creat a complete bubble free gap free bond and heat will get trapped between

Hope this helps

Good luck chap

Dont let your fingers touch the mating surfaces in any way and secret is less is more,the mating surfaces want as little gap as possible.
Use Filter paper to clean the TIM off and plenty of elbow grease,put your proc in an old board to clean it as you dont want TIM anywhere near your socket.....heard too many people getting TIM in sockets (god knows how,but they do)
As for the uneven temp,points to heatspots caused by bubbbles...
If your unsure about how much to use,take 2 sheets of glass and try your technique out,draw an outline of your cpu on the glass and try to keep within the lines,hold it up to the light and you should be able to see thru it. Then you get a feel for it,many TIM's have different viscousity and require heavy pressure to spread while others (normally the white sillicone kind) spread very well.

Hang on a minute. With these direct contact heatpipes don't you have to work TIM into the gaps between the heatpipes for them to work properly?

Yes,using a credit card and wiping off the excess.
