Temps To High

**Ozzie82** · #1 28th Jul 2008, 10:20

Hi guys , bit of a pickle here.

I own a p&b system running the Quad Q6600 2.4GHz

well i used to have a board in it called the denver10, the cpu temp was always idle at 33c and under load was just around 40>42c which was for me very good.

I now have a new board because old board died.

So i fired it up on saturday after fitting the new board in and started to run core temp

My temps are way higher than they was before and i have even underclocked it to 1.2Ghz but idle temp is still same as it is at max 2.4GHz give opr take a few c*

case temp is a cool 39c and air temp in roon be about 15 > 20c i guess no wthat it sfew hopt days this past while, but if case temp is ok then it must be cpu related

Its at 1.2GHz now atm and temps are 48c 49c 45c 45c at idle and now its at 1.2GHz lo they only go to 52c .

I have tried every way to put on the thermal paste but it wont have any better effect.

I cant figure out why now the temps are much higher than they were before. my idle temps now are higher than my max temps before at full 100% cpu usage.

It cant be case cooling or anything cos the only thing that is changed within the case is the motherboard so if it was showing cool temps before it should still show them same temps.

am very confused and my cpu is underclocked to 1.2GHz just to keep them from boiling up .

anyone have any ideas at all whats wrong?

fan is running normal psu is running fine and no defects anywhere apart from these high temps

there's really no difference between the motherboards tbqh, it has to be the way you reseated the HSF or applied the compound

did you clean all the old stuff off? what did you clean it with?

Hi Carbon

I cleaned it with acetone and a lint free cloth , i have reseated it 4 times now trying all ways of applying the paste over the cores and all ways produced the same high temps

the four ways i have tried are

a vertical line ,horizontal line , tictac drop ,using plastic bag to smear a thin layer over the entire surface. all which produced the exact same high temps.

cant work this out at all :(

Maybe the sensor is not working properly, did you check it the bios to see what temps you are getting, bios temps are generally around 80% load, also try changing the app you are using to monitor your temps

Edit: Just a thought but did you take the fan off aswell? As you may have put it back on the wrong way around

Yep Social , i tried the bios aswell same temp as in core temp proggy, you could be right there, the sensors could be buggered. al have to get some other device to test the temps , i have a had held Infrared Temperature Measurement gun for fridge freezers

so its just a matter of trying to find a way to test the cpu temp with that without the fan on top, hmm could be very risky that but , shows case temp as what the bios is telling me

You could buy one of these, you might be able to find one local to you, then you will know for sure
Give or take 2 or 3c, I would say if you can put it just around the cpu and heatsink

Hi Ozzie:

I'm suffering from a similar problem, although I replaced both my motherboard and CPU. Still I got a 15 degree increase in temps. My current system is running both the motherboard and CPU at anything between 45 and 50 degrees idle.

One thing that sprung to my mind might be the difference in chipset, although my old modo had an Nvidia 650i chip which was known to run fairly hot. As such, I replaced the stock northridge cooler with a passive copper one and even applied some thermal grease. I can't quite believe that that might have been the reason why my system was running so cool...

Luckily for me, my old CPU still works and my old motherboard still has some life in it. I'll be doing some testing tomorrow afternoon in order to see what the old processor does in the new motherboard and vice versa. If you can hang out another 24 hours, maybe the results of my tests might be a guideline for you.

hehe ya , thats a handy device ,Social

i did try that lazer gun and it wasnt showing any hot temps within case at least ,so senors must be ok ,i checked room temp and there is a great difference from 2pm and 2am nearly 10c room temp and thast what i think is causing most of my heat problem but there still higher than what they should be

o bummer man

sry to here that but am glad you posted as now you are dealing with same problem live time

i will be here always post you results if you dont mind doing that ,that would be a great idea and i could relate to your changes. thankyou for that and hope too you get it sorted

mobo is the MS-7366 (P6NGM) wasnt a major buy but just one to get me back up and running as i am still after an asus board sometime in near future.

i think i do have same chipset as you , Desertfish (Nvidia MCP73U/PV/V Chipset)

Finished testing, and I have to say, the results are somewhat surprising...

Mobo-1: Asus P5N-E Sli (Nvidia 650i Chipset)
Mobo-2: Asus P5K Pro (Intel P35 Chipset)

CPU-1: Intel E2160 (1.8Ghz - 800Mhz FSB - 1MB L2 Cache)
CPU-2: Intel E8500 (3.16Ghz - 1333Mhz FSB - 6MB L2 Cache)

Results:

Test-1: P5N-E + E2160 (CPU Temp = 31c / Mobo Temp = 30c)
Test-2: P5N-E + E8500 (CPU Temp = 32c / Mobo Temp = 31c)
Test-3: P5K Pro + E2160 (CPU Temp = 40c / Mobo Temp = 38c)
Test-4: P5K Pro + E8500 (CPU Temp = 41c / Mobo Temp = 39c)

I would have thought that the difference in CPU speed would have generated a bigger temperature difference between the E8500 and E2160... However, after running the above combinations for about 30 minutes each, the average temperature difference between the 2 CPU's is only about 1 degree C... It seems that the motherboard itself if the main factor in causing temperature differences...

(Note: All temperature measurements were carried at idle speeds using the Asus Probe II utility that came with both the motherboards. CPU fan speed was the same in all cases: 2776 RPM).
